Noob Question: Number of unique addresses are back to almost pre Jan 2017 level. I am not sure what it exactly means. My guess is that they only count wallets with non-zero bitcoins. Doesnt it mean we lost almost all the users that we had gained over last year. Please correct me what I am missing.

Bitcoin Fullnode Install Guide for Dummies ;-)

Bitcoin Fullnode Install Guide for Dummies ;-)
Feel free to stop at Level 0 or Level 1, which is fine. More advanced configs are offered to those with more tech savvy. This guide, obviously assumes a Windows 10 install, but other OSes work fine, just find a different guide. BTW, the "For Dummies" is a callback to a set of "tech" books in the 90's intended to be as easy as possible. It is in jest and not intended to insult the reader. Finally, if you dislike the formatting, a well formatted copy can be found here
There is a fairly small subset of Bitcoin users that run a full node. I think the idea of running a full node has gotten a bad rap over the years since there is so much talk about running on a Raspberry Pi, or getting zippy SSDs. Although all of this can be fun, it is often not really required at all. Here are some ways to run a full node starting with the very simple. I'll get into more complex configs, but these are all optional.

Tech Skill Level: 0 (the basics)

  1. Download Bitcoin Core
  2. Launch the downloaded installer and install the app
  3. Launch the installed "Bitcoin Core" app and let it run overnight
In many cases, thats it. If your running a new machine with a fairly good internet connection, 8 or 9 hours will be enough to complete the "Initial Block Download" (IBD). This may fill up your drive a bit, but again, on most new machines, 300 GB of space isn't that hard to come by.

Tech Skill Level: 1 (encrypted wallet)

One thing we left out in the level-0 exercise is encrypting your wallet. It's easy enough to do well, but a bit more difficult to do right. The main challenge is that humans generate really poor passwords. If you want a good password, the best way is to use something called "diceware". Basically, you just grab 4 or 5 dice and each throw of the dice represents a certain word on a special list. The throw {1,4,5,3,1} for example would be the word camping on the EFF-diceware-wordlist. So you repeat this a few times until you have a list of 8 or so words which becomes the passphrase you use to encrypt your wallet. Write it down, it is always hard to remember at first. So at level-1 your list becomes:
  1. Download Bitcoin Core
  2. Launch the downloaded installer and install the app
  3. Launch the installed "Bitcoin Core" app and let it run overnight
  4. Choose Encrypt Wallet from the Settings menu
  5. Enter your 8 word (or so) passphrase generated using the Diceware method

Wallet Encryption Dialog

Tech Skill Level: 2 (enable pruning if needed)

Though I said "300 GB of space isn't hard to come by", some times it actually is. If space is an issue, a simple way to fix it is to tell bitcoin to simple take less space. This is called "pruning" and can take that number from 300 GB down to below 5 GB. If you can't find 5 GB, then you'll have to read ahead to level-4 to add USB storage. But the good news is, enabling pruning is pretty easy, we just add another step to our working list:
  1. Download Bitcoin Core
  2. Launch the downloaded installer and install the app
  3. Launch the installed "Bitcoin Core" app and let it run overnight
  4. Do the wallet encryption steps here if you wish
  5. Choose Options from the Settings menu
  6. Choose Prune block storage to: and select the max size for the blocks to use
  7. Exit and restart the bitcoin application for the changes to take effect

Pruning Dialog
Note, even setting this to 1 GB will still leave you with about a 4.5 GB install. The blocks take up a lot of space, but the chainstate and other folders eat up at least 3.5 GB and they can't be pruned. Also, be aware, to disable pruning requires you to perform the entire IBD again. While pruned some other functions my be disabled as well, so just know that pruning does limit some functionality.

Tech Skill Level: 3 (verify the installer)

Although this is arguably something that should be done at level-0, some find the intricacies of comparing hash (thumbprint) values to be tedious and beyond the scope of a beginner. You will find these types of hash compares suggested quite often as a way to prevent running tainted programs. Programs are often tainted by bad disk or network performance, but most often, taint is malicious code inserted by viruses or malware. This is a way to guard yourself against those types of attacks.
What I cover here is a very basic comparison on the certificate, but a more thorough verification advised by mosts uses a program called Gpg4Win, and is beyond the scope of this beginners guide. But regardless, most users should strive to do this minimum level of validation.
  1. Download Bitcoin Core
  2. Launch the downloaded installer
  3. When prompted "Do you want to allow..." click Show more details
  4. In the details section select Show information about the publisher's certificate
  5. In the certificate window select the Details tab
  6. In the Details tab Subject should start with "CN = Bitcoin Core Code Signing Association"
  7. Ensure Thumbprint in Details reads ea27d3cefb3eb715ed214176a5d027e01ba1ee86
  8. If the checks pass, click OK to exit the certificate window and Yes to allow the installer to run.
  9. Launch the installed "Bitcoin Core" app and let it run overnight
  10. Do the wallet encryption steps here if you wish
  11. Do the optional pruning steps here if you wish

Certification Validation Windows
Note: The certificate used to sign the current Bitcoin installer is only valid from March 2020 to March 2021. After that point the thumbprint on the certificate will change. This is by design and intentional. If your reading this post after March 2021, then it is understood that the thumbprint has changed.

Tech Skill Level: 4 (use secondary storage)

We glossed over the "new machine with fairly good internet" part. Truth be known many people do not have fairly new machines, and find the IBD to take longer than the "over night" best wishes. For most people the slowdown is the disk access when calculating what is called chainstate. This requires fast random reads and writes to the disk. If you have an SSD disk, this will be no problem, but if you have a non-SSD "spinning" disk, random writes are always slow. Though an SSD will speed things up, they are pricey, so a nice middle ground may be a simple high-end USB key drive. You can get some with 10 to 15 MB/s random writes for $20 on Amazon. This is usually a order of magnitude faster than a "spinning" disk. And with pruning (see level-2), a small USB drive should be fine.
Once you decide on a drive, the tricky part will be to enable external storage. It requires editing a configuration file and adding a line. First, we want to create a directory on the key drive. You will need to determine the drive letter of your USB key drive. For the sake of this example, we will assume it is D:, but you must determine this yourself and correct the example. Once you know the drive letter, create a blank folder on the drive called Bitcoin. So for this example, creating Bitcoin on drive D: will create the path D:\Bitcoin. Once done, assuming that D: is your drive, here are the new steps including the edit of the configuration file:
  1. Download Bitcoin Core
  2. Launch the installer, verify it, then run it
  3. Launch the installed "Bitcoin Core" app and let it run overnight
  4. Do the wallet encryption steps here if you wish
  5. Do the optional pruning steps here if you wish
  6. Launch "Notepad" by typing "Notepad.exe" in the windows search bar then click Open
  7. Type the line datadir=D:\Bitcoin (depending on your drive letter) in the blank file
  8. Choose Save from the File menu in notepad
  9. Type %APPDATA%\Bitcoin\bitcoin.conf (note the percent signs) in the File name box
  10. Select All Files from the Save as type dropdown
  11. Click the Save button and overwrite the file if prompted
  12. Exit and restart the bitcoin application for the changes to take effect

Save As Dialog
Now that you've reached this level of technical expertise, there are many new configuration options that you can begin to modify if you wish. Most configuration data is contained in the bitcoin.conf file and learning how to maintain it is a key step for a node operator.

Tech Skill Level: 5 (all other customizations)

Here's a short list of various things you can ADD to your bitcoin.conf file. You generally just add a new line for each configuration settings.
  • addresstype=bech32
  • changetype=bech32
The addresstype / changetype allows your wallet to use the native-segwit (bech32) format. This is the most efficient and inexpensive way to spend bitcoin, and is a recommended configuration. The default uses something called p2sh-segwit which is more compatible with older wallets, but more expensive to spend.
  • minrelaytxfee=0.00000011
Changing the minrelaytxfee setting allows you to help propagate lower fee transactions. It will require more memory but TXN memory is capped at 300 MB by default anyways, so if you have enough memory, it is a good setting to choose.
  • dbcache=2048
The dbcache setting controls how many MB of memory the program will use for the chainstate database. Since this is a key bottleneck in the IBD, setting this value high (2048 MB) will greatly speed up the IBD, assuming you have the memory to spare
  • blocksdir=C:\Bitcoin
  • datadir=D:\Bitcoin
In level-4 we discussed moving the datadir to a fast external storage, but the majority of the space used for bitcoin is the blocks directory (blocksdir). Although you should always use for fastest storage for datadir, you are free to use slow storage for blocksdir. So if you only want to consume a small amount of your SSD (assumed D:) then you can keep your blocks on your slow "spinning" drive.
  • upnp=1
One of the harder challenges you may face running a node, is to get incoming connections. If you are lucky, you may find that your firewall and network HW support the uPnP protocol. If they do, this setting will allow bitcoin to configure uPnP to allow incoming connections to your node. Other methods exist to make your node reachable, but they are well beyond the scope of this guide.

Everyday info sec, hardcore info sec, and DNMs

Edit: Since first post I have updated a few sections with additional information.
I recommend reading it all even if it is very long, I might have placed some relevant info in different sections while thinking about what else needed to be added, plenty of steps remains mostly the same except when I comment directly on it. It is not necessary to do 100% security all the time, unless you absolutely need it, combining some high and some lower security ideas for a balance of security and convenience is useful.
I will base this mostly on Windows, Linux users probably know this, and I have no idea how apple machines work (tho many things in here are still relevant for other operating systems, as they are just general tips)
Disclaimer: There are certainly other steps that can make you more anonymous or safer, however I think for most people this will surfice. Any software I recommend should be independently verified for security, and examples of software are not to be taken as endorsements. I simply use examples and give recommendations when I believe it necessary, or helpful.
I will not really differentiate between anonymity and security, they are often the same thing. As such the word security can mean either more anonymous, less vulnerable, or both.
Everyday Simple Info Sec:
-There could be a hidden administrator user on your PC, make sure to change its password
(Snapchat msgs, reddit dms, discord msgs, are just a few examples of msgs that are never encrypted)
-Any info even send in encrypted msgs (and obviously non encrypted) should still be kept with possible deniability, don't say "I'm gonna do MDMA", say "I'm going out with molly."
-DO NOT STORE ANY PASSWORDS ON GOOGLE, IF GOOGLE LOGIN IS AUTHENTICATED IT WILL AUTFILL ALL PASSWORDS IT HAS SAVED (same with other similar services) (This means if you are logged in to chrome and someone has access to your machine, they can auto fill passwords without entering a single password)
-use a rememberable passphrase, especially for your master key ring aka password manager A long sentence that is memorable makes an okay password (decent example,: "I met my wife at Little Ceasers for the first time on 07/09/20" better even if it's just something you know, if its impersonal, and if you can add special characters or numbers that you won't forget) (A better example for a passphrase is: "There is 0nly 0ne letter that d0esn’t appear in any U.S. state nameQ")
-Purge your internet activity frequently, there's a reason why I only have one post, and a few comments appearing in my account, but thousands of kama. Exposing information needlessly is not good.
-Never post private information publicly, and if you do, do it vaguely as possible. (Example: Not "I'm 15", say "I'm a teenager") Do not post any vital information ever, no birthdays, mother's maiden name, age, or anything you have ever seen in a security question. Never post your current activities while they are ongoing. You going on a vacation? Don't announce it to the world, taking picture there? Post them when you are home.
-Rethink how you do security questions. Many answers to security questions can be found in your internet history. One could use the first word of the security question as an answer, or a different sceme that will mean you always remember it. (Security question need to go, the amount of personal info an average person puts on the internet makes it easy to attack anything using security question)
High level crimimal information security:
The motto here is, "All the Security, All the Time" As one fuck up can end with you leaving a lick of traceability, and you could be fucked.
Pre Note: All of your software should always be up to date. Also even perfect info sec does not guarantee you are completely safe, a new zero day (exploit) can still fuck you, but good info security makes you significantly safer, by eliminating as many attacks as possible.
-Get a new device (or make a already owned device seem like you never owned it, do this only if you know how to, there's a lot of stuff that goes into that, like changing your mac adress etc) buy with cash, and your face covered, preferably far away from where you live. (Do I need to specify to not bring your phone or anything else that tracks your location to anywhere you want to go anonymously?) (Be aware that even hardware can have vulnerabilities, many cpus have known vulnerabilities, I can't list them all, do some research before buying)
-If you know how to use Tails (A linux distro designed for Info sec) use that, preferably on a USB. (Or learn how to use tails, its better, but complicated) Otherwise a clean copy of windows (make sure its not in any way associated with you) can do the job too, tho not as well. (Using a VM might give extra security, since VMs usually erase all data and RAM they were using on shutdown)
-Get a non tracking VPN, Enable the kill switch (a setting that disables all traffic that doesn't go through the VPN) (change your firewall settings to only allow the traffic from the VPN, windows guide (Change settings so only traffic from the tor application is send) Edit: (Due to complaints: do not use vpn over tor, use tor over vpn. tor over vpn has no notable downside, if the VPN logs it makes no difference, your ISP will always log anyways, and vpns remove other attack vectors and also provide backup security should tor fail. Again even if the VPN tracks you only change the people doing the tracking, but now you are further removed making it more anonymous and also with less vulnerabilities)
-rember privacy settings, cookie cleaner, and antivirus, password (There could be a hidden administrator user on your PC, make sure to change its password)
-Always use the device on a non admin account
-Ideally use this device only on networks that are not connected with you. Such as public networks (try to never use the same public networks twice, move around) (a home network should be fine now, as it should never be exposed, but more security is always better) (Its just a conveniences vs security trade)
-Never use accounts that have been exposed to lower security on higher security machines
-your browser is now TOR (or your preferred security focused browser, if you dont plan on using onion ) Make sure you get the standalone version of tor not the addon build (the standalone is safer, because there are less settings and options to tweak)
-Change your tor settings, to safest mode, enable a bridge (to my knowledge there's no difference in security between the build in bridges in tor), enable automatic updates, set duckduckgo onion as your primary browser. Set dark.fail onion page as your home page. (Or your preferred privacy search engine and onion directory)
How to use dark net markets (DNMs)
If you finished your High Security setup, we can dive right in. Otherwise go do that. This is where all that is essential.
Quick info on Tor, and onion sites. There is no search engine. It's all based of directories and addresses you are given by others. Tor will likely not be very quick, it has to pass through multiple networks to get to the destination. DNMs sometimes exit scam, an exit scam is when a market shuts down completely and takes all the money, this is a risk when using DNMs, it's not too common but happens maybe 0-4 times a year. The admins of thoese servers need to get out at some point, before they get jailed, so they exit the game, and scam everyone out of their money.
-A very useful onion directory is dark.fail it has a lot of links, for all kinds of stuff. News, email, DNMs, Psychonautwiki (harm reduction website), forums etc. (Other directories also exist)
-Pick a market, preferably one that handles secure connection server side instead of requiring you to establish the secure connection. Then create an account. Your account once created should include an entry box in your profile for a pgp key, post your PUBLIC key in there. (Verify the link is not a scam, most markets should provide a pgp signature)
-Next is currency setup. All major cryptocurrency exchangers can be used, I can recommend coin base but there could be better ones out there. Unless you find a small non U.S., exchange, they will always ask for your identity. So unless you can find a trustworthy exchange that doesn't ID, you will need to give it to them. (Side note, all major crypto exchangers report to the IRS, if the IRS asks you if you bought cryptocurrency and you bought while having IDed yourself SAY YES, DO NOT COMMIT TAX FRAUD WHEN THEY KNOW YOU DID)
-Transfer (monero you can send directly, btc you should scramble) to your wallet. There are two options a cold wallet (physical) or a software wallet. Software wallets usually dont cost anything so I recommend them, even if often less safe. Electrum is easy to use, and pretty safe. You can also do your own research and find a wallet that fits your needs.
-now you are ready to buy, only buy using escrow (it means the money is held by the market as a middle man until the product is delivered, they will also handle any issues like wrong quantity, cuts, etc), judge the reviews for a product, and if available look at the history of the vendor, until you find a product from a vendor you trust. (I recommend to buy within your country as much as possible, so it doesn't go through customs, it's very rare that something is found, but it can happen)
-now you get to buy, depending on market, you either have cryptocurrency stored in their wallets (not recommend, you will lose it in an exit scam) or you can send it every order. When you send your delivery adress (or the one you want it to go to) encrypt the adress using the sellers public key. Make sure the adress is correct.
-wait for the product, make sure to extend the escrow until the product arrives, if you can't extend it anymore dispute the order, and a moderator will step in
-test the product, use it, and leave a review. PLEASE LEAVE A REVIEW, DNMs only work because of reviews.
Edit: Didn't imagine I would write over 15000 words. Oh well, it was fun. Hope it helps, if you have any questions feel free to ask.
No idea how long this will stay up, I might purge it in 7 days, or never.

The greatest wealth transfer of this century! An analysis: British-US-Chinese Empires: Gold, Silver, Bitcoin, Ethereum!

"Inflation makes you pay 50 dollars for the 20 dollar haircut you used to get for 5 dollars when you had hair!"
Let's embark on a journey that made the United States the number 1 economy of the world.

1. Despite the British Empire's claim that it would for ever remain the leading empire,history can serve as a harbinger for what's to come...

At the peak of its power, in 1913, "the empire on which the sun never sets", controlled 25% of the planet's land mass and about the same percentage of the world's population. Britain was both the naval an imperial power of the 19th century, and between 1812-1914, its dominance resulted in relative peace in Europe and the rest of the world. The industrial revolution transformed Britain into the workshop of the world.
By the start of the 20th century things changed as both Germany and the United States started to challenge Britain's economic and influential leadership. As often happened during human history such challenging lead to war and although Britain achieved its largest territorial influence after WW1, the war had destroyed much of its economic strength, with losses in industrial and military power marking the begin of its demise.
During WW2, Japan occupied Britain's colonies, and after WW2, India, Britain's most valuable and populous possession, achieved independence. Much of the British Empire's influence is now enshrined in the Commonwealth Charter, stating shared values like democracy, human rights and the rule of law.
The United Kingdom's pound sterling was its world's reserve currency during its reign and by controlling the supply of money, Britain was able to influence its global power.
"Permit me to issue and control the money of a nation, and I care not who makes its laws!" Mayer Amschel Rothschild

2. The US Empire repeats this blueprint by claiming the U.S. Dollar's reserve currency status as its birthright!

The Federal Reserve Act.
The Panic of 1907 triggered many American's belief that The Federal Reserve Act, passed by the 63rd United States Congress and signed into law by President Woodrow Wilson on December 23, 1913, was necessary for financial and economic stability. The law created the Federal Reserve System, the central banking system of the United States.
The Bretton Woods System.
The FED ended immobile reserve issues and the inelastic currency problems and successfully internationalized the U.S Dollar as the global reserve currency. The usage of the prior nationally used U.S. Dollar expanded a first time when the Allies agreed to the terms of the Bretton Woods System, establishing the rules for commercial as well as financial regulations among the United States and its allies. Canada, Western Europe, Australia and Japan accepted the U.S. Dollar, which was backed by a gold exchange standard, making the U.S. Dollar "as good as gold". This was only possible because the United States controlled two thirds of the world's gold reserves.
Soviet representatives, who claimed that institutions like the IMF and the International Bank for Reconstruction and Development (IBRD) were Wall Street branches, didn't participate in Bretton Woods and later proved to be right, as the United States printed too much money (not backed by its gold reserves) to wage war on Vietnam, destroying a big part of the value of the U.S. Dollars held by its allies, due to the inflation of the U.S. Dollar money supply.
Yet, the initial demand for U.S. dollars created the American way of life: a consumer driven economy fueled by products made outside the U.S. in return for U.S. Dollars. As the Allied countries couldn't really buy any "Made in America"-products, due to the fact that the United States' elites rather outsourced their manufacturing, they instead invested their hard labor into U.S. Treasuries.
On August 1971, President Richard Nixon announced the unilateral cancellation of the direct international convertibility of the United States dollar to gold, in a response to halt the Allied countries' continuous attempts to exchange their U.S. Dollars for Gold. By 1973, the Bretton Woods system was replaced by the current freely floating fiat currency system.
The petro dollar system.
The second wave of U.S. Dollar adoption was the result of the petro dollar, making the global trade of oil U.S. Dollar denominated. Every country on this planet needed and still needs oil to operate and grow its economy, creating an enormous growth in U.S. Dollar demand and like mentioned before, those dollars had to be earned. Especially China served the United States consumer model by producing almost everything Americans can buy in Wall Mart and other stores. By relying on the U.S. Dollar reserve currency status, the American elites have made the mistake of outsourcing manufacturing to China, as often predicted by Donald Trump in the 1980's. The y figured it was easier to just print wealth.
The tradewar.
President Donald Trump, decided it was time to bring jobs back to the U.S. and started an ongoing trade war with China, the country that supplied the U.S. consumer driven economy, and proud owner of $1.07 trillion in Treasury holdings. The trade war has negatively impacted the economies of both the United States and China and will most likely result in the decoupling of both economies.
What is to come? My personal insights.
I see huge problems for the U.S. and the rest of the western liberal democracies. But especially the United States, who's currency amounts to no less than 60% of all the world's reserve assets, is vulnerable if and when China who only accounts for 1 or 2 %, says it is time for change. Most likely we will experience another banking crisis, with or without Covid-19, and unfortunately a bigger one when compared to the 2008 dissaster. Did you know that the global debt tripled since then? Many economists and politicians advocate the end of the U.S. Dollar reserve currency system and predict a reset. Every financial system has a limited lifespan similar to a human live: it is created, it grows, it matures, and unfortunately, it ages, weakens and dies. It happened to the Brittish Pound Sterling, and I am afraid that the days of this financial hegemony are numbered as well.
And I did write "afraid", why?
History tells us that these transition periods are particularly dangerous and have often led to full-blown military conflicts if not world wars. The current wealth transfer, the result of manufacturing outsourcing to mainland China, impoverished the United States and destroyed its middle class. President Donald Trump's analysis that the U.S. needs a strong manufacturing base is correct, yet without its allies the United States will not be able to turn the tide.
It took China decades to build its manufacturing base, and President Trump doesn't have the privilege of having the political luxury to design five year plans, as the United States capitalistic and political model specializes more on presidential campaigning and less on economic planning, which is exactly China's strength.

3. The Chinese 'digital' empire.

China is ideally positioned to become the new global power: it produces many of our products and dominates most supply chains. It has been hoarding gold and mines most of the Bitcoin. It might just have the right reserve assets to back its DCEP, the digital Yuan, which will be pilot tested during the 2022 Winter Olympics hosted by China. Despite the fact that the United States and other western nations might not want to adopt the Yuan or allow it to be part of the world's reserve assets, China can demand payment in Yuan for its products. It's that simple! This is why outsourcing is such as stupid economic voluntarily yet fatal policy. If you only print money and don't produce goods, how long will the world play ball?
One of the results of Trump's trade war is that China and other countries such as Russia and Iran no longer want to be vulnerable to U.S. sanctions that come in the shape of being denied access to the financial system through Swift. The United States can indeed destroy a big part of Iran's economy, but Iran is now becoming a big cryptocurrency player. In other words, bullying those countries might work in the short-term, but in the long-term they will simply adopt a new standard: and I believe that the Yuan will likely play a major role in the financial system they will adopt.
This trend means that the expansion of the demand in U.S. Dollars will stop and reverse, when countries no longer want to use the currency whose issuer can economically destroy them through sanctions. The alternatives for such countires are cryptocurrencies like Bitcoin, Ethereum and many others, national CBDC's (Central Bank Digital Currencies), and the adoption of the digital Yuan.
This digital Yuan will be attached to the One Belt, One road initiative, finding adoption whilst developing huge infrastructure projects that will lead to a Eurasian trading zone. If the U.S. Military leaves the Middle East, as Trump brings home troops, this will create the right conditions for China to emerge as the victor.

4. Surveillance Capitalism - Insights on the DCEP (Digital Currency Electronic Payment, DC/EP):

  1. This centralized digital financial system works on blockchain and cryptographic principles and aims to increase the circulation of the RMB, in the hope it can become a reserve currency like the U.S. Dollar.
  2. Created and sanctioned by the Chinese Government, it is the only legal digital currency in China.
  3. The system offers Chinese regulators better monitoring abilities and will be an efficient tool against anonymous counterfeiting, money laundering and illegal financing. At the same time it reduces costs involved in maintaining and recycling bank notes and coins.
  4. As mentioned above, China aims to bypass Swift, which it regards to be a U.S. entity, and will be able to collect real-time data related to money creation, bookkeeping, essential information for the implementation of monetary policies.
  5. The pilot institutions for DCEP, China Construction Bank, Agricultural Bank of China, Bank of China and Industrial and Commercial Bank of China, will serve as a production test for China's new currency system, after which the DCEP will be distributed to large fintech companies such as Tencent and Alibaba to be used in WeChat Pay and AliPay. Transfers will not go through bank accounts, but through electronic wallets.
  6. By mandating that all merchants who accept digital payments must accept DCEP, the DECP will become the most accepted digital currency in the world.

5. Sings of hope.

If the United States adopts blockchain and issues a CBDC (Central Bank Digital Currency) backed by Bitcoin, they will have a reasonable chance to offer the western democracies a new type of dollar standard that can be an anchor versus the coming RMB. If not, I fear the worst is yet to come for the U.S. Dollar and its economy.
Many smart American economists and Wall Street goeroe's have finally figured out the remarkable strength of Bitcoin, the world's first and most favorite digital form of gold.
Some of the smartest investment capitalists like Ray Dalio and Warren Buffet have allocated more money into gold, a clear sign of trouble. Bitcoin might be a step too far for Warren Buffet, but rest assure that Wall Street investment management companies have figured it out by now, have you?
You can expect more institutions to allocate a % of their portfolio's wealth into Bitcoin and other cryptocurrencies, as a hedge against the systemic risk in our global financial system, which will inevitable start feeling the effects of the trillions that have been printed.

What I currently use for privacy (after almost 2 years of long investing into it)

First of all, my threat model: I'm just an average person that wants to AVOID the maximum I can to be monitored and tracked by the government and big corps, a lot of people out there REALLY hate me and I've gone through lots of harassment and other stuff, I also plan to take my activism and love for freedom more seriously and to do stuff that could potentially lead me to very high danger or even put my life on the line. That being said, my main focus is on something that is privacy-friendly but also something with decent security (no point having a lot of privacy if a script kiddie can just break into it an boom, everything is gone) anonymity is also desirable but I'm pretty aware that true 100% anonymity is simply not possible and to achieve the maximum you can of it currently you'd have to give up A LOT of stuff in which I don't think I really could. So basically, everything that I said + I don't want to give up some hobbies of mine (as playing games etc)
Here's what I use/have done so far, most of it is based on privacytools.io list and research I've done.
Google Pixel 3a XL running GrapheneOS
Apps: Stock apps (Vanadium, Gallery, Clock, Contacts etc) + F-DROID, NewPipe, OsmAnd+, Joplin, Tutanota, K-9 Mail, Aegis Authenticator, KeePassDX, Syncthing, Signal, Librera PRO, Vinyl, Open Camera and Wireguard.
I also use BlahDNS as my private DNS.
Other smartphone stuff/habits: I use a Supershieldz Anti Spy Tempered Glass Screen Protector on my phone and I also have a Faraday Sleeve from Silent Pocket which my phone is on most of the times (I don't have smartphone addiction and would likely advice you to break free from smartphone addiction if you have it). I NEVER use bluetooth (thank god Pixel 3a have a headphone jack so yeah, no bluetooth earphones here) and always keep my Wi-Fi off if I'm not using it.
I have a desktop that I built (specs: Asus B450M Gaming, AMD Ryzen 3 3300X, Radeon RX 580 8GB, 16GB DDR4 2666Mhz, 3TB HDD, 480GB SSD) that is dualbooted with QubesOS and Arch Linux.
Qubes is my main OS that I use as daily driver and for my tasks, I use Arch for gaming.
I've installed linux-hardened and its headers packages on my Arch + further kernel hardening using systctl and boot parameters, AppArmor as my MAC system and bubblewrap for sandboxing programs. I also spoof my MAC address and have restricted root access, I've also protected my GRUB with password (and use encrypted boot) and have enabled Microcode updates and have NTP and IPV6 disabled.
Also on Arch, I use iptables as a firewall denying all incoming traffic, and since it's my gaming PC, I don't game on the OS, instead, I use a KVM/QEMU Windows VM for gaming (search "How I Built The "Poor-Shamed" Computer" video to see what I'm talking about) I also use full disk encryption.
E-Mails: I use ProtonMail (Plus Account paid with bitcoin) and Tutanota (free account as they don't accept crypto payment yet, come on Tutanota, I've been waiting for it for 2 years already) since I have plus account on ProtonMail it allows me to use ProtonMail Bridge and use it on Claws Mail (desktop) and K-9 Mail (mobile) as for Tutanota I use both desktop and mobile app.
Some other e-mails habits of mine: I use e-mail aliases (ProtonMail plus account provides you with 5) and each alias is used for different tasks (as one for shopping, one for banking, one for accounts etc) and none of my e-mails have my real name on it or something that could be used to identify me. I also highly avoid using stuff that require e-mail/e-mail verification for usage (e-mail is such a pain in the ass tbh) I also make use of Spamgourmet for stuff like temporary e-mail (best service I found for this doing my research, dunno if it's really the best tho, heard that AnonAddy does kinda the same stuff but dunno, recommendations are welcomed)
Browsers/Search Engine: As mentioned, I use Vanadium (Graphene's stock browser) on mobile as it is the recommended browser by Graphene and the one with the best security for Android, for desktop I use a Hardened Firefox (pretty aware of Firefox's security not being that good, but it's the best browser for PC for me as Ungoogled Chromium is still not there in A LOT of things + inherent problems of Chrome as not being able to disable WebRTC unless you use an extension etc) with ghacks-user.js and uBlock Origin (hard mode), uMatrix (globally blocking first party scripts), HTTPS Everywhere (EASE Mode), Decentraleyes (set the recommended rules for both uBlock Origin and uMatrix) and Temporary Containers as addons. I also use Tor Browser (Safest Mode) on a Whonix VM on Qubes sometimes. DuckDuckGo is my to-go search engine and I use DNS over HTTPS on Firefox (BlahDNS as my provider once again)
browsing habits: I avoid JavaScript the maximum I can, if it's really needed, I just allow the scripts temporarely on uBlock Origin/uMatrix and after I'm done I just disable it. I also generally go with old.reddit.com instead of reddit.com (as JavaScript is not required to browse the old client), nitter.net for checking twitter stuff (although I rarely have something peaking my interest on Twitter) and I use invidious.snopyta.org as youtube front-end (I do however use YouTube sometimes if a video I wanna see can't be played on invidious or if I wanna watch a livestream) and html.duckduckgo.com instead of duckduckgo.com other than avoiding JavaScript most of my browsing habits are just common sense at this point I'd say, I also use privatebin (snopyta's instance) instead of pastebin. I also have multiple firefox profiles for different tasks (personal usage, shopping, banking etc)
VPN: I use Mullvad (guess you can mention it here since it's PTIO's recommended) paid with bitcoin and honestly best service available tbh. I use Mullvad's multihop implementation on Wireguard which I manually set myself as I had the time and patience to learn how.
password manager: KeePassXC on desktop and KeePassDX on my smartphone, my password database for my desktop is stored on a USB flash driver I encrypted with VeraCrypt.
some other software on desktop: LibreOffice (as a Microsoft Office substitute), GIMP (Photshop substitute), Vim (I use it for multiple purposes, mainly coding IDE and as a text editor), VLC (media player), Bisq (bitcoin exchange), Wasabi (bitcoin wallet), OBS (screen recording), Syncthing (file sync), qBitTorrent (torrent client) and Element (federated real-time communication software). I sadly couldn't find a good open-source substitute to Sony Vegas (tested many, but none was in the same level of Vegas imo, KDENLive is okay tho) so I just use it on a VM if I need it (Windows VM solely for the purpose of video editing, not the same one I use for gaming)
router: I have an Asus RT-AC68U with OpenWRT as its firmware. I also set a VPN on it.
cryptocurrency hardware wallet: I store all of my cryptocurrency (Bitcoin and Monero) on a Ledger Nano S, about 97% of my money is on crypto so a hardware wallet is a must for me.
I have lots of USB flash drivers that I use for Live ISOs and for encrypted backups. I also have a USB Data Blocker from PortaPow that I generally use if I need to charge my cellphone in public or in a hotel while on a trip (rare occasion tbh).
I have a Logitech C920e as webcam and a Blue Yeti microphone in which I never let them plugged, I only plug them if it's necessary and after I'm done I just unplug them.
I also have a Nintendo Switch Lite as a gaming console that I most of the times just use offline, I just connect to the internet if needed for a software update and then just turn the Wi-Fi off from it.
Other Habits/Things I've done:
payments: I simply AVOID using credit card, I try to always pay on cash (I live in a third-world country so thank god most of people here still depend on cash only) physically and online I try my best to either by using cryptocurrency or using gift cards/cash by mail if crypto isn't available. I usually buy crypto on Bisq as I just don't trust any KYC exchange (and neither should you) and since there aren't many people here in my area to do face to face bitcoin trade (and I'm skeptical of face to face tbh), I use the Wasabi Wallet (desktop) to coinjoin bitcoin before buying anything as this allows a bit more of privacy, I also coinjoin on Wasabi before sending my bitcoins to my hardware wallet. I also don't have a high consumerism drive so I'm not constantly wanting to buy everything that I see (which helps a lot on this criteria)
social media/accounts: as noted, aside from Signal and Element (which I don't even use that often) I just don't REALLY use any social media (tried Mastodon for a while but I was honestly felt it kinda desert there and most of its userbase from what I've seen were some people I'd just... rather don't hang with tbh) and, althoug not something necessary is something that I really advise people to as social media is literally a poison to your mind.
I also don't own any streaming service like Netflix/Amazon Prime/Spotify etc, I basically pirate series/movies/songs and that's it.
I've also deleted ALL my old accounts from social media (like Twitter etc) and old e-mails. ALL of my important and main accounts have 2FA enabled and are protected by a strong password (I use KeePass to generate a 35 character lenght password with numbers, capital letters, special symbols etc, each account uses a unique password) I also NEVER use my real name on any account and NEVER post any pictures of myself (I rarely take pictures of stuff if anything)
iot/smart devices: aside from my smartphone, I don't have any IOT/smart device as I honestly see no need for them (and most of them are WAY too expensive on third-world countries)
files: I constatly backup all of my files (each two weeks) on encrypted flash drivers, I also use BleachBit for temporary data cleaning and data/file shredding. I also use Syncthing as a substitute to stuff like Google Drive.
Future plans:
learn to self-host and self-host an e-mail/NextCloud (and maybe even a VPN)
find something like BurneHushed but FOSS (if you know any please let me know)
So, how is it? anything that I should do that I'm probably not doing?

Some newbie questions about Trezor device and bitcoin wallets

I have never owned bitcoin before, but I studied how it works, so I think I have some understanding. I also studied options and it seems hardware wallet is the way to go for safety reasons.
So, question number One, am I correct that:
Unlike a bank account, where you keep one account usually, with bitcoin you keep generating new addresses, so if you own 1 bitcoin, you don't store it on one address, rather, you own many addresses, each containing part of your bitcoin, and when you spend, you just expend some of the addresses and throw them away, and when you receive, you generate new addresses for every transaction, so you accumulate these addresses that each are like a banknote of sorts, each having their own nominal value, and then you spend those banknotes and never use those addresses again. Right?
Question number Two, am I correct that:
All the addresses are generated from a certain big number, "master key" of sorts, which is private to me, which can be written in a form of "seed" which is what the device will give me when initialized, which is what I can use to recover my master key if I lose or break the device?
Question number Three, who does the address generation for bitcoin wallets for new incoming transactions? I assume it's the online wallet Trezor uses, right? So the device does not store any addresses of bitcoin wallets, right? It only stores my master key?
Assuming all are correct, can you please explain, in simpliest terms, how do I restore these addresses themselves, should Trezor online wallet be unavailable? I mean, it's hardly a possibility, but assume I have my seed, or even my Trezor device, but Trezor online wallet is unavailable. Assume I made hundreds of bitcoin transactions and my bitcoin is stored in hundreds of small pieces on different addresses. How do I recover all those? How do I know when to stop, when I have recovered them all? Assuming I don't know the amount I totally own by heart, so I cannot know when to stop (When I found all my bitcoin)?
I mean, it's unlimited, right, the amount of bitcoin addresses that can be generated from my "master key" of my Trezor? So how do I know which of them contain bitcoin? Like, say I have used 200 of them and 100 of them still contain bitcoins, and I lose the device, and have to restore from seed, how does it know that it has to generate only those 200, like, how does it know it doesnt have to generate more addresses, maybe those other addresses contain some bitcoin on them too?
Or does it, generate them always in the same order, so if it sees only blank unused addresses, it assumes it's time to stop? Like, if address 0-200 are all used but 200-300 are all unused still, it assumes it's fine to stop checking?
Also, on an unrelated note, how can I be sure I made no mistake in recording the seed? Can I just wipe the device and restore it from seed right after initializing it and receiving a small bitcoin transaction, to test it and be sure that I can recover my bitcoin in case I lose it? Is the device unlimited in terms of how many times it can be wiped and restored?
Thanks in advance!

How to buy bitcoin instantly (Please read description!!!!)

Okay, so im 17 in Canada and I turn 18 in 3months but really want to buy a crypto currency before 2020 because i know the price will rise. What my plan was is to find a site where you don't need id verification phone number verification and buy directly with visa or PayPal and i store them on a phone wallet until i can move them to a ledger wallet but this proved to be a pain in the ass so PLEASE PLEASEEE if you know any sites where i can buy cryptocurrency with a visa card or PayPal instantly let me know
I already tried the following which didnt work for me
-Bull bitcoin

Fun with low fee TXNs on Mainnet

Here's a 0.493 sat/vB TXN I put on mainnet today. You'll have to use the SoChain block explorer to see it though. I give it a 3% chance of getting confirmed, but we'll wait and see. The TXN is a donation to [email protected] since I use their seeder for my network herder.
So last month, I voiced the unpopular opinion that node operators should lower the minrelaytxfee setting to allow low-fee TXNs to propagate more freely throughout the network. Then I asked why miners weren't mining 0.999 sat/vB TXNs during idle periods since it should be more profitable than mining no TXNs at all. Finally I wrote a node herder to walk the network looking for node operators that were running minrelaytxfee below the default (1000 sat). After walking about 26% of the network, turns out about 5% of nodes are allowing low fee TXNs.
So in that vein of discussion, I decided to just sign some low-fee TXNs and send them to the 5% of nodes I found and see what happens. To my surprise it showed up on one of the 23 block explorers I tried after broadcasting it. Surprisingly, that comes out to about 5% of explorers accepting low fee TXNs as well. So hopefully 5% or so of the miners will confirm low fee TXNs. We'll see.
BTW, to do this, this is what I did.
  1. Pair my HW wallet to Electrum
  2. Use the paytomany Electrum API to craft a TXN below 1 sat/vB
  3. Import the TXN to sign in Electrum
  4. Ran a full node with minrelaytxfee set to 1 sat (0.001 sat/vB)
  5. Walked the network to find a good number of low-fee peers
  6. Use bitcoin addnode API to herd my node to the low-fee peers I discovered.
  7. Use bitcoin sendrawtransaction API to broadcast TXN
Wait and see if it can propagate to a miner and if a miner will accept it.
BTW, there is a PR to lower the minrelaytxfee in core, but it's dragged on for years. The setting was lowered about every year or so in the early days, but hasn't been touched for many years now.

Technical: Taproot: Why Activate?

This is a follow-up on https://old.reddit.com/Bitcoin/comments/hqzp14/technical_the_path_to_taproot_activation/
Taproot! Everybody wants it!! But... you might ask yourself: sure, everybody else wants it, but why would I, sovereign Bitcoin HODLer, want it? Surely I can be better than everybody else because I swapped XXX fiat for Bitcoin unlike all those nocoiners?
And it is important for you to know the reasons why you, o sovereign Bitcoiner, would want Taproot activated. After all, your nodes (or the nodes your wallets use, which if you are SPV, you hopefully can pester to your wallet vendoimplementor about) need to be upgraded in order for Taproot activation to actually succeed instead of becoming a hot sticky mess.
First, let's consider some principles of Bitcoin.
I'm sure most of us here would agree that the above are very important principles of Bitcoin and that these are principles we would not be willing to remove. If anything, we would want those principles strengthened (especially the last one, financial privacy, which current Bitcoin is only sporadically strong with: you can get privacy, it just requires effort to do so).
So, how does Taproot affect those principles?

Taproot and Your /Coins

Most HODLers probably HODL their coins in singlesig addresses. Sadly, switching to Taproot would do very little for you (it gives a mild discount at spend time, at the cost of a mild increase in fee at receive time (paid by whoever sends to you, so if it's a self-send from a P2PKH or bech32 address, you pay for this); mostly a wash).
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash, so the Taproot output spends 12 bytes more; spending from a P2WPKH requires revealing a 32-byte public key later, which is not needed with Taproot, and Taproot signatures are about 9 bytes smaller than P2WPKH signatures, but the 32 bytes plus 9 bytes is divided by 4 because of the witness discount, so it saves about 11 bytes; mostly a wash, it increases blockweight by about 1 virtual byte, 4 weight for each Taproot-output-input, compared to P2WPKH-output-input).
However, as your HODLings grow in value, you might start wondering if multisignature k-of-n setups might be better for the security of your savings. And it is in multisignature that Taproot starts to give benefits!
Taproot switches to using Schnorr signing scheme. Schnorr makes key aggregation -- constructing a single public key from multiple public keys -- almost as trivial as adding numbers together. "Almost" because it involves some fairly advanced math instead of simple boring number adding, but hey when was the last time you added up your grocery list prices by hand huh?
With current P2SH and P2WSH multisignature schemes, if you have a 2-of-3 setup, then to spend, you need to provide two different signatures from two different public keys. With Taproot, you can create, using special moon math, a single public key that represents your 2-of-3 setup. Then you just put two of your devices together, have them communicate to each other (this can be done airgapped, in theory, by sending QR codes: the software to do this is not even being built yet, but that's because Taproot hasn't activated yet!), and they will make a single signature to authorize any spend from your 2-of-3 address. That's 73 witness bytes -- 18.25 virtual bytes -- of signatures you save!
And if you decide that your current setup with 1-of-1 P2PKH / P2WPKH addresses is just fine as-is: well, that's the whole point of a softfork: backwards-compatibility; you can receive from Taproot users just fine, and once your wallet is updated for Taproot-sending support, you can send to Taproot users just fine as well!
(P2WPKH and P2WSH -- SegWit v0 -- addresses start with bc1q; Taproot -- SegWit v1 --- addresses start with bc1p, in case you wanted to know the difference; in bech32 q is 0, p is 1)
Now how about HODLers who keep all, or some, of their coins on custodial services? Well, any custodial service worth its salt would be doing at least 2-of-3, or probably something even bigger, like 11-of-15. So your custodial service, if it switched to using Taproot internally, could save a lot more (imagine an 11-of-15 getting reduced from 11 signatures to just 1!), which --- we can only hope! --- should translate to lower fees and better customer service from your custodial service!
So I think we can say, very accurately, that the Bitcoin principle --- that YOU are in control of your money --- can only be helped by Taproot (if you are doing multisignature), and, because P2PKH and P2WPKH remain validly-usable addresses in a Taproot future, will not be harmed by Taproot. Its benefit to this principle might be small (it mostly only benefits multisignature users) but since it has no drawbacks with this (i.e. singlesig users can continue to use P2WPKH and P2PKH still) this is still a nice, tidy win!
(even singlesig users get a minor benefit, in that multisig users will now reduce their blockchain space footprint, so that fees can be kept low for everybody; so for example even if you have your single set of private keys engraved on titanium plates sealed in an airtight box stored in a safe buried in a desert protected by angry nomads riding giant sandworms because you're the frickin' Kwisatz Haderach, you still gain some benefit from Taproot)
And here's the important part: if P2PKH/P2WPKH is working perfectly fine with you and you decide to never use Taproot yourself, Taproot will not affect you detrimentally. First do no harm!

Taproot and Your Contracts

No one is an island, no one lives alone. Give and you shall receive. You know: by trading with other people, you can gain expertise in some obscure little necessity of the world (and greatly increase your productivity in that little field), and then trade the products of your expertise for necessities other people have created, all of you thereby gaining gains from trade.
So, contracts, which are basically enforceable agreements that facilitate trading with people who you do not personally know and therefore might not trust.
Let's start with a simple example. You want to buy some gewgaws from somebody. But you don't know them personally. The seller wants the money, you want their gewgaws, but because of the lack of trust (you don't know them!! what if they're scammers??) neither of you can benefit from gains from trade.
However, suppose both of you know of some entity that both of you trust. That entity can act as a trusted escrow. The entity provides you security: this enables the trade, allowing both of you to get gains from trade.
In Bitcoin-land, this can be implemented as a 2-of-3 multisignature. The three signatories in the multisgnature would be you, the gewgaw seller, and the escrow. You put the payment for the gewgaws into this 2-of-3 multisignature address.
Now, suppose it turns out neither of you are scammers (whaaaat!). You receive the gewgaws just fine and you're willing to pay up for them. Then you and the gewgaw seller just sign a transaction --- you and the gewgaw seller are 2, sufficient to trigger the 2-of-3 --- that spends from the 2-of-3 address to a singlesig the gewgaw seller wants (or whatever address the gewgaw seller wants).
But suppose some problem arises. The seller gave you gawgews instead of gewgaws. Or you decided to keep the gewgaws but not sign the transaction to release the funds to the seller. In either case, the escrow is notified, and if it can sign with you to refund the funds back to you (if the seller was a scammer) or it can sign with the seller to forward the funds to the seller (if you were a scammer).
Taproot helps with this: like mentioned above, it allows multisignature setups to produce only one signature, reducing blockchain space usage, and thus making contracts --- which require multiple people, by definition, you don't make contracts with yourself --- is made cheaper (which we hope enables more of these setups to happen for more gains from trade for everyone, also, moon and lambos).
(technology-wise, it's easier to make an n-of-n than a k-of-n, making a k-of-n would require a complex setup involving a long ritual with many communication rounds between the n participants, but an n-of-n can be done trivially with some moon math. You can, however, make what is effectively a 2-of-3 by using a three-branch SCRIPT: either 2-of-2 of you and seller, OR 2-of-2 of you and escrow, OR 2-of-2 of escrow and seller. Fortunately, Taproot adds a facility to embed a SCRIPT inside a public key, so you can have a 2-of-2 Taprooted address (between you and seller) with a SCRIPT branch that can instead be spent with 2-of-2 (you + escrow) OR 2-of-2 (seller + escrow), which implements the three-branched SCRIPT above. If neither of you are scammers (hopefully the common case) then you both sign using your keys and never have to contact the escrow, since you are just using the escrow public key without coordinating with them (because n-of-n is trivial but k-of-n requires setup with communication rounds), so in the "best case" where both of you are honest traders, you also get a privacy boost, in that the escrow never learns you have been trading on gewgaws, I mean ewww, gawgews are much better than gewgaws and therefore I now judge you for being a gewgaw enthusiast, you filthy gewgawer).

Taproot and Your Contracts, Part 2: Cryptographic Boogaloo

Now suppose you want to buy some data instead of things. For example, maybe you have some closed-source software in trial mode installed, and want to pay the developer for the full version. You want to pay for an activation code.
This can be done, today, by using an HTLC. The developer tells you the hash of the activation code. You pay to an HTLC, paying out to the developer if it reveals the preimage (the activation code), or refunding the money back to you after a pre-agreed timeout. If the developer claims the funds, it has to reveal the preimage, which is the activation code, and you can now activate your software. If the developer does not claim the funds by the timeout, you get refunded.
And you can do that, with HTLCs, today.
Of course, HTLCs do have problems:
Fortunately, with Schnorr (which is enabled by Taproot), we can now use the Scriptless Script constuction by Andrew Poelstra. This Scriptless Script allows a new construction, the PTLC or Pointlocked Timelocked Contract. Instead of hashes and preimages, just replace "hash" with "point" and "preimage" with "scalar".
Or as you might know them: "point" is really "public key" and "scalar" is really a "private key". What a PTLC does is that, given a particular public key, the pointlocked branch can be spent only if the spender reveals the private key of the given public key to you.
Another nice thing with PTLCs is that they are deniable. What appears onchain is just a single 2-of-2 signature between you and the developemanufacturer. It's like a magic trick. This signature has no special watermarks, it's a perfectly normal signature (the pledge). However, from this signature, plus some datta given to you by the developemanufacturer (known as the adaptor signature) you can derive the private key of a particular public key you both agree on (the turn). Anyone scraping the blockchain will just see signatures that look just like every other signature, and as long as nobody manages to hack you and get a copy of the adaptor signature or the private key, they cannot get the private key behind the public key (point) that the pointlocked branch needs (the prestige).
(Just to be clear, the public key you are getting the private key from, is distinct from the public key that the developemanufacturer will use for its funds. The activation key is different from the developer's onchain Bitcoin key, and it is the activation key whose private key you will be learning, not the developer's/manufacturer's onchain Bitcoin key).
Taproot lets PTLCs exist onchain because they enable Schnorr, which is a requirement of PTLCs / Scriptless Script.
(technology-wise, take note that Scriptless Script works only for the "pointlocked" branch of the contract; you need normal Script, or a pre-signed nLockTimed transaction, for the "timelocked" branch. Since Taproot can embed a script, you can have the Taproot pubkey be a 2-of-2 to implement the Scriptless Script "pointlocked" branch, then have a hidden script that lets you recover the funds with an OP_CHECKLOCKTIMEVERIFY after the timeout if the seller does not claim the funds.)

Quantum Quibbles!

Now if you were really paying attention, you might have noticed this parenthetical:
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash...)
So wait, Taproot uses raw 32-byte public keys, and not public key hashes? Isn't that more quantum-vulnerable??
Well, in theory yes. In practice, they probably are not.
It's not that hashes can be broken by quantum computes --- they're still not. Instead, you have to look at how you spend from a P2WPKH/P2PKH pay-to-public-key-hash.
When you spend from a P2PKH / P2WPKH, you have to reveal the public key. Then Bitcoin hashes it and checks if this matches with the public-key-hash, and only then actually validates the signature for that public key.
So an unconfirmed transaction, floating in the mempools of nodes globally, will show, in plain sight for everyone to see, your public key.
(public keys should be public, that's why they're called public keys, LOL)
And if quantum computers are fast enough to be of concern, then they are probably fast enough that, in the several minutes to several hours from broadcast to confirmation, they have already cracked the public key that is openly broadcast with your transaction. The owner of the quantum computer can now replace your unconfirmed transaction with one that pays the funds to itself. Even if you did not opt-in RBF, miners are still incentivized to support RBF on RBF-disabled transactions.
So the extra hash is not as significant a protection against quantum computers as you might think. Instead, the extra hash-and-compare needed is just extra validation effort.
Further, if you have ever, in the past, spent from the address, then there exists already a transaction indelibly stored on the blockchain, openly displaying the public key from which quantum computers can derive the private key. So those are still vulnerable to quantum computers.
For the most part, the cryptographers behind Taproot (and Bitcoin Core) are of the opinion that quantum computers capable of cracking Bitcoin pubkeys are unlikely to appear within a decade or two.
For now, the homomorphic and linear properties of elliptic curve cryptography provide a lot of benefits --- particularly the linearity property is what enables Scriptless Script and simple multisignature (i.e. multisignatures that are just 1 signature onchain). So it might be a good idea to take advantage of them now while we are still fairly safe against quantum computers. It seems likely that quantum-safe signature schemes are nonlinear (thus losing these advantages).

Help! Hacked , get no help from coinbase!

Hello .
For a week ago i got totally hacked, I am from Denmark. My card was used to purchase for 3 x 2000 eu. (I am a single father) Got it stopped, but ofcourse with troubles. But the "hackers" managed to sell ALL my investments in my coinbase wallet, where i kept all my long term buys. Its not a lot now, just around 200$ worth, but i send and buy bitcoin often also. Know i lost all my investments, they got converted to BTC, and just before they send the btc away , I managed to block my account..
Now I tried three times filling a form, email , calling 100 times, but no number on their support site has people answering. I can´t log in to my account, I dont know whats happening with it. I get no emails, nothing in response.. What should I do ? Furthermore I am about to sell my house, and wanted to invest larger amounts of money in crypto, but now I an affraid, is this the support people normally get?

Sorry for grammar, English is not my native language :)

Zano Newcomers Introduction/FAQ - please read!

Welcome to the Zano Sticky Introduction/FAQ!

Hopefully any questions you have will be answered by the resources below, but if you have additional questions feel free to ask them in the comments. If you're quite technically-minded, the Zano whitepaper gives a thorough overview of Zano's design and its main features.
So, what is Zano? In brief, Zano is a project started by the original developers of CryptoNote. Coins with market caps totalling well over a billion dollars (Monero, Haven, Loki and countless others) run upon the codebase they created. Zano is a continuation of their efforts to create the "perfect money", and brings a wealth of enhancements to their original CryptoNote code.
Development happens at a lightning pace, as the Github activity shows, but Zano is still very much a work-in-progress. Let's cut right to it:
Here's why you should pay attention to Zano over the next 12-18 months. Quoting from a recent update:
Anton Sokolov has recently joined the Zano team. ... For the last months Anton has been working on theoretical work dedicated to log-size ring signatures. These signatures theoretically allows for a logarithmic relationship between the number of decoys and the size/performance of transactions. This means that we can set mixins at a level from up to 1000, keeping the reasonable size and processing speed of transactions. This will take Zano’s privacy to a whole new level, and we believe this technology will turn out to be groundbreaking!
If successful, this scheme will make Zano the most private, powerful and performant CryptoNote implementation on the planet. Bar none. A quantum leap in privacy with a minimal increase in resource usage. And if there's one team capable of pulling it off, it's this one.

What else makes Zano special?

You mean aside from having "the Godfather of CryptoNote" as the project lead? ;) Actually, the calibre of the developers/researchers at Zano probably is the project's single greatest strength. Drawing on years of experience, they've made careful design choices, optimizing performance with an asynchronous core architecture, and flexibility and extensibility with a modular code structure. This means that the developers are able to build and iterate fast, refining features and adding new ones at a rate that makes bigger and better-funded teams look sluggish at best.
Zano also has some unique features that set it apart from similar projects:
Privacy Firstly, if you're familiar with CryptoNote you won't be surprised that Zano transactions are private. The perfect money is fungible, and therefore must be untraceable. Bitcoin, for the most part, does little to hide your transaction data from unscrupulous observers. With Zano, privacy is the default.
The untraceability and unlinkability of Zano transactions come from its use of ring signatures and stealth addresses. What this means is that no outside observer is able to tell if two transactions were sent to the same address, and for each transaction there is a set of possible senders that make it impossible to determine who the real sender is.
Hybrid PoW-PoS consensus mechanism Zano achieves an optimal level of security by utilizing both Proof of Work and Proof of Stake for consensus. By combining the two systems, it mitigates their individual vulnerabilities (see 51% attack and "nothing at stake" problem). For an attack on Zano to have even a remote chance of success the attacker would have to obtain not only a majority of hashing power, but also a majority of the coins involved in staking. The system and its design considerations are discussed at length in the whitepaper.
Aliases Here's a stealth address: ZxDdULdxC7NRFYhCGdxkcTZoEGQoqvbZqcDHj5a7Gad8Y8wZKAGZZmVCUf9AvSPNMK68L8r8JfAfxP4z1GcFQVCS2Jb9wVzoe. I have a hard enough time remembering my phone number. Fortunately, Zano has an alias system that lets you register an address to a human-readable name. (@orsonj if you want to anonymously buy me a coffee)
Multisignature (multisig) refers to requiring multiple keys to authorize a Zano transaction. It has a number of applications, such as dividing up responsibility for a single Zano wallet among multiple parties, or creating backups where loss of a single seed doesn't lead to loss of the wallet.
Multisig and escrow are key components of the planned Decentralized Marketplace (see below), so consideration was given to each of them from the design stages. Thus Zano's multisig, rather than being tagged on at the wallet-level as an afterthought, is part of its its core architecture being incorporated at the protocol level. This base-layer integration means months won't be spent in the future on complicated refactoring efforts in order to integrate multisig into a codebase that wasn't designed for it. Plus, it makes it far easier for third-party developers to include multisig (implemented correctly) in any Zano wallets and applications they create in the future.
(Double Deposit MAD) Escrow
With Zano's escrow service you can create fully customizable p2p contracts that are designed to, once signed by participants, enforce adherence to their conditions in such a way that no trusted third-party escrow agent is required.
The Particl project, aside from a couple of minor differences, uses an escrow scheme that works the same way, so I've borrowed the term they coined ("Double Deposit MAD Escrow") as I think it describes the scheme perfectly. The system requires participants to make additional deposits, which they will forfeit if there is any attempt to act in a way that breaches the terms of the contract. Full details can be found in the Escrow section of the whitepaper.
The usefulness of multisig and the escrow system may not seem obvious at first, but as mentioned before they'll form the backbone of Zano's Decentralized Marketplace service (described in the next section).

What does the future hold for Zano?

The planned upgrade to Zano's privacy, mentioned at the start, is obviously one of the most exciting things the team is working on, but it's not the only thing.
Zano Roadmap
Decentralized Marketplace
From the beginning, the Zano team's goal has been to create the perfect money. And money can't just be some vehicle for speculative investment, money must be used. To that end, the team have created a set of tools to make it as simple as possible for Zano to be integrated into eCommerce platforms. Zano's API’s and plugins are easy to use, allowing even those with very little coding experience to use them in their E-commerce-related ventures. The culmination of this effort will be a full Decentralized Anonymous Marketplace built on top of the Zano blockchain. Rather than being accessed via the wallet, it will act more as a service - Marketplace as a Service (MAAS) - for anyone who wishes to use it. The inclusion of a simple "snippet" of code into a website is all that's needed to become part a global decentralized, trustless and private E-commerce network.
Atomic Swaps
Just as Zano's marketplace will allow you to transact without needing to trust your counterparty, atomic swaps will let you to easily convert between Zano and other cyryptocurrencies without having to trust a third-party service such as a centralized exchange. On top of that, it will also lead to the way to Zano's inclusion in the many decentralized exchange (DEX) services that have emerged in recent years.

Where can I buy Zano?

Zano's currently listed on the following exchanges:
It goes without saying, neither I nor the Zano team work for any of the exchanges or can vouch for their reliability. Use at your own risk and never leave coins on a centralized exchange for longer than necessary. Your keys, your coins!
If you have any old graphics cards lying around(both AMD & NVIDIA), then Zano is also mineable through its unique ProgPowZ algorithm. Here's a guide on how to get started.
Once you have some Zano, you can safely store it in one of the desktop or mobile wallets (available for all major platforms).

How can I support Zano?

Zano has no marketing department, which is why this post has been written by some guy and not the "Chief Growth Engineer @ Zano Enterprises". The hard part is already done: there's a team of world class developers and researchers gathered here. But, at least at the current prices, the team's funds are enough to cover the cost of development and little more. So the job of publicizing the project falls to the community. If you have any experience in community building/growth hacking at another cryptocurrency or open source project, or if you're a Zano holder who would like to ensure the project's long-term success by helping to spread the word, then send me a pm. We need to get organized.
Researchers and developers are also very welcome. Working at the cutting edge of mathematics and cryptography means Zano provides challenging and rewarding work for anyone in those fields. Please contact the project's Community Manager u/Jed_T if you're interested in joining the team.

Got to meet an online friend for the first time yesterday.

So how I met this guy,
4 years ago I wasn't in a good position. Had got a back injury at my place of employment, and after diagnosis was pretty much told they didn't have work for me.
Was able to file FMLA and was on workman's compensation, short term disability, and got all the state help ...well 9 months passed and that shit was all dried up, and I was still not able to work.
I kept a log of every visit, each morning, and every phone conversation on another site like reddit. Now the reason I did this was for my records, and for others to know it isn't just as easy as "sue them".
Well after that 9 months with meds, and costs we were broke....I mean broke. To top it off they had a guy following me gathering evidence to prove their case.
It was just demoralizing to say the least.
Well on that other site I said that we were worried about finances. On average 1000 people viewed each submission, and while it never got comments people did read it.
Someone suggested that I make a Bitcoin wallet. So I did and the site admin said to post my wallet id....I didn't think anything of it, and mind you this site has become (now) one of the most infamous for racism and hate known on the net now, but I been there since it started.
It's free speech mind you.....so because you don't like it doesn't mean they can't say what they want.......
Soon as I posted the link to my wallet people began to send shit....5 bucks here 10 bucks there. And then one guy sent 15 bucks. He messaged me and asked if I got it.
I did after a few and confirmed.....then he said ok wanted to be sure.
I looked again a few minutes later and suddenly a half a Bitcoin was in there.....9,000 usd. I asked if he did that, and he confirmed he did.
Got his number and called him crying, wife was too.....so we got to know him....very introvert too. We found out he like Xbox and we showed him ark survival.....he been playing it ever since.
We just became great firends and he never wanted repayment....just someone to help is all.
Yesterday I got to finally meet him. Shook his hand....showed me where he lives, and I said let's go to the range. He only ever fired a gun once.....we changed that lol.
Afterwords I took him to dinner at outback steakhouse.
He makes the 6th person I met in person from that site, and the 20th from here and there combined.
I try to make a difference in real life with people as well as what I can do here or there. It lets you know that it's actually people you talk to.
Gives you some relationship if you will......if you can I highly suggest it as you can make a difference for others when they need it.
Plus.....gun range! Controlled setting with no expectations. I just let someone get used to it...know what it feels like to hold a gun and what to expect.
So yeah....was a good day.

Running My Own Tor Bitcoin Lightning Node

I've been using my own bitcoin lightning/full node for about a month now and would like to share my findings as well as ask a few questions to the community.
For those that might be curious as to my setup, I am using a Lenovo M900 ThinkCentre with a 1 TB Samsung SSD and 32GB of ram. I'm actually running several VM's on it, for different reasons. One of which is the full Bitcoin/lightning node using Ubuntu Desktop in which I dedicate 8 GB to (more than enough) and most of my disk space to. I wanted a power efficient setup so that I could keep it running 24/7 and this is about as good as it gets short of a Raspberry Pi. When I only have my Bitcoin VM running, I'm consuming ~10 Watts. With everything else running it's ~30 Watts. I bought all of the equipment used (apart from the ram) so it was very cost effective.
What I've learned in my experience:
Any info would be appreciated. If anybody has any question that they would like to ask me, feel free to ask!

ALL of my stored cryptocurrency has been STOLEN from my Ledger Nano S!

Hey everyone... I recently logged into my account in Ledger Live expecting to see a great increase with the price of Bitcoin moving up. Instead of seeing what I expected to be about $13,000.00 worth of Bitcoin, Ethereum, Bitcoin Cash, and Ethereum Classic, I see $0.00 balance on everything! I am absolutely blown away, saddened, and disappointed. I purchased the Nano S over two years ago BECAUSE of security. Now, it seems I have lost literally everything, and there is no phone number to contact this company, only through emails, which they have not responded to. I can clearly see all of the funds from every crypto I was holding were sent out to different addresess which have now all been confirmed on the blockchain. Does anyone here have any ideas at all as to what could have happened, or what I can do here? The only way I know of, that the funds can be accessed, is with the 24 word recovery phrase, and that has been written down on the card, by me 3 years ago, and been kept safely in a burn safe box all this time. So how in the world does something like this happen!? I heard about their data breach, and leaking customers info a couple weeks ago and I am wondering if somehow, someway, that access was gained to my wallet with info that was exposed? Can somebody help me here, or has this happened to anyone else in the last few days? Thanks.

Okay, after reading through all these comments, and everybody saying I must have entered my passphrase on my computer or phone at some point, you guys are right. I forgot, that 3 years ago, when I purchased the Ledger, I wrote down the recovery phrase, and it's been in the burn safe since. BUT, I also, can't believe I'm saying this, but I did enter it into my phone, and sent it to my own email address, where it has been ever since, I guess thinking if I ever lost the paper with the 24 word phrase, or it was stolen, I would have it there, so I could recover my assets. Well, I guess that means somebody else can recover my assets too. :( This IS MY FAULT, and I take full blame for it. I guess I just never thought, without somebody having access to my e-mail that anyone would ever possibly be able to get access to it. It's just so weird, that it's been 3 years, and the assets were just now stolen. I've had close to that amount in there for a couple years now. Again, I thank you for your help and research, i'm to blame here. $13,000 lesson learned. NEVER INPUT YOUR RECOVERY PHRASE INTO DIGITAL FORMAT. Still wish there was something that could be done, but I know once it's gone, it's gone in crypto. Such a shame now that it looks like Bitcoin is beginning it's bull run.

Not sure why this wasn't posted before: Olaf Carlson on Eth's crazy gas situation. DeFi choked every Dapp sector out, but Polkadot welcomes them.

For any new guys, Olaf Carlson runs the biggest crypto VC fund, Polychain Capital. He is bullish on Polkadot.
Interviewer - "Let's talk about the fee issue on Ethereum. At the moment a simple trade on Uniswap can cost something like $40 and more complex transactions for yield farming are even more expensive. Do you think Ethereum will scale in time to retain all its market share in DeFi considering that the explosion is already here and already pushing Ethereum's limits?"
Olaf - "In short, I don't think it will be able to scale fast enough. Whether that just slows down the market or whether aspects of the market go to other chains its too early to say. DeFi is very exciting for Ethereum but in a weird way is actually really really bullish in my mind for systems like Polkadot or Dfinity that are from an engineering perspective just candidly far ahead of Ethereum. They don't have the network effects, users, wallet installs, or anything that Ethereum has, but Polkadot is live and working and scalable right now, today. And so I do think we'll see a lot of DeFi migrate from Ethereum to Polkadot in maybe the short term. Long term I'm hopeful that Ethereum can scale and upgrade and change. But that all said, what's much more exciting to me about these new systems launching that have either better scalability features or like Web Assembly or WASM based virtual machine compatibility so you can write programs in many different programming languages all of these sorts of features are exciting not just to narrowly compete in DeFi. It's exciting to me because it will enable new types of applications that simply aren't possible on Ethereum today. Much in the way that Ethereum enabled all sorts of applications that weren't possible on bitcoin. Today we know that what's exciting about Ethereum is not that it narrowly competes with bitcoin's value proposition but rather expanded the scope of what was possible for the entire crypto universe. And we got things like stablecoins, things like lending contracts, ICOs, DeFi. And I think that systems like Polkadot are going to once again expand the universe of what is possible. Its not a zero sum game where its narrowly like which chain is gonna win DeFi. I think that's a very myopic view and it shows a lack of imagination about how many different types of applications these smart contract type structures will affect. So I'm very optimistic about scalability across the entire ecosystem but I'm less confident about the short term timeline of Ethereum. I just think that DeFi is moving way faster - like by over ten times at least - maybe closer to 50 or 100 times faster than Ethereum core protocol development. And I see no reason for that to change. I don't think Ethereum core protocol development has ever been fast and I don't see any reason to think that it will get faster. And DeFi has always been fast and I don't see any reason that it will get slower. So you add that combination of factors and yeah I do think that you will see applications migrating to more scalable chains. [...] I'm having conversations now with teams that have yet to launch on Ethereum that are saying should we launch on Ethereum or should we launch on another chain? Because the fee situation is completely - its really bad - like I don't think... it's not like this is a bump in the road. It is existential for the entire landscape of applications we're talking about. Right now you have to be transacting at least a thousand dollars per transaction for any of this to make sense from a fee perspective. And I would say that's the absolute baseline [...] more realistically you have to be using five or ten thousand dollars to really accept the kind of fees we're talking about. And a lot of people are using five or ten thousand dollars but obviously that's pricing a huge number of people out of this market."
Some examples:
Due to insane gas prices, Trial of the Gods card minting and trading will be deferred until the release of Immutable X
I tried to buy 2 cards, worth $0.24 each. After gas, my transaction is $6.80!
Hi, new player using Metamask to buy a couple dollars worth of cards on the marketplace, but everytime the gas price is something of >$15.
$25 fee to buy a $2 card
$50 transaction fee to roll the dice
Minimum bet is now 3 ether to reduce gas cost as a %
Overall, all the fees came up to about $140. Fees for Coinbase was about $2 and the fee to create the bet was like $130
Some dapps like God's Unchained and Augur are looking into L2 solutions, but those come with massive risks from a company perspective. See the Lightning Network's astounding lack of adoption as the primary example. Other dapps are just calling it quits:
Incorrect Assumption #2: Scalability wouldn’t be a problem This was an explicit assumption in our presentations: usability was more important than scalability, and given that there were so many deployed L2 solutions on the market (like xDai), as soon as scalability became a problem we would all move there. This turned out a deadly assumption: as soon as we had our email sign-in solution ready, gas fees on Ethereum made the whole process unworkable.
Reading between the lines: Even if L2 solutions were perfect today, most (non DeFi) dapps are still dead if they stay on Ethereum. Users need to pay upwards of $20 to enter and exit that L2, and I'm not sure if that's changing anytime soon. Gas fees are just not viable for the vast majority of dapps until Eth 2.0, and the part of Eth 2.0 that brings scalability is not happening until 2023~

Getting started as a bitcoin cash merchant

So I've spent some time looking into various APIs and services, trying to get a basic merchant setup working usable for development, with a working testnet. The quality of the services offered and documentation is lacking, to say the least.
So I've taken a step back and decided I would try to get this working from "first principles", basically setting up a node and using the related APIs. I first tried the BCHD node which was looking promising, until the testnet version of it got into a loop where it kept complaining about some invalid transactions over and over and never seemed to recover.
The I tried "Bitcoin Cash Node", which is an awful name for search engines btw. It could really need a more unique and searchable name. After some struggle and careful reading of startup options and configuration files, I managed to get nodes up an running (testnet and mainnet) and in such a state that they answer to REST and JSONRPC calls.
I have transferred some bitcoin on testnet to a know address, using a public "faucet" that works (also a bit hard to find). I know that I managed to get that part working, as I've successfully looked up the balance of that address using a few of the public blockchain lookup tools.
What I havent' quite figured out is how to look up that address on my locally running node. Most of the API deals with transactions, not addresses. There aren't many APIs that accept addresses. scantxoutset might work, but it uses terms as "scan", which indicates it's not a "low cost" operation (which I would expect).
So I'm wondering, does this really mean that most bitcoin nodes really isn't usable for looking up addresses?? Or to turn it around, can anybody recommend bitcoin cash nodes that offers an easy to use API for looking up payment related things, like addresses?
Final note, I know how wallets etc work. The reason I'm trying to implement similar functionality from scratch is to understand all the details. And because a merchant typically can't just accept the current limited functionality with wallets, which seems focused on a single user's need, not what a merchant would need (gap issue etc).
And fwiw, I've also tested the "bitbox" API (which does not have a working testnet) and "fullstack" API (which has a working testnet, although documentation isn't complete). So I know about other ways of doing similar stuff. I'm just trying to minimize the number of external things I need to depend on while also figuring out how this can be done straight from running nodes.

[21:12, 24/09/2020] Scumm: Please make sure you send confirmation immediately
So finally I did not send him payment proof,I sent him a spoofed link to fetch his IP with a link to "payment proof" and got his IP and location (cant showr a real link bc it has my IP in it...) And was like " oh hey how is the whether in Irele, Nigeria??"
Needless to say he blocked me straight away after I called him a disgraceful sc*m but hey..... I still called the corresponding banks, the UK Fraud Action and the FBI just to make sure and shared all of the details without any editting :)
Have fun "mate"! If they can freeze only 1 $ and return it to a likely victim, I am more then happy
Cheers dont get scammed!
TL/DR: Scammed a Nigerian scammer into sending me real accounts, names and details in UK and US (mules) to forward to the police and may or may not have donated 500 to charity.

What is my BTC address? Your BTC address is a string of 26-35 letters and numbers that identify your Bitcoin wallet. BTC addresses begin with either a 1 or a 3 and are case-sensitive.. When you want to receive funds, this is the information that you provide to the person paying you. To find an old bitcoin wallet, you’ll simply need to retrace your steps. We know that it sounds like common sense but it really is the only way to find them. If you really say that you were into BTC as much as you say you were, then there should be traces of information all over your computer, phone, email, etc. The Bitcoin wallet is in fact a file that we need to send and receive bitcoins; it may be stated that this “document” “contains” our Bitcoins, though in fact what it comprises are cryptographic keys (personal, unique, unrepeatable and secret keys) which make us owners of our bitcoins and let us authorize payments (move possession of the bitcoins). All Bitcoin Core (BTC) addresses will start with the number "1" or "3". What can make things a little confusing sometimes, is that Bitcoin Cash (BCH) addresses can also start with either a " 1 " or " 3 " if being displayed in the old " legacy " format. This bitcoin address checker will lookup the selected bitcoin address and review multiple factors to give an overall wallet score. Taking into account the account balance, the amount sent, the amount received, the number of transactions and other factors this bitcoin wallet address checker will help you to know if the address you are planning ...
