Bech32

Bech32 is a segwit address format specified by BIP 0173 and BIP 0350. This address format is also known as "bc1 addresses". Bech32 is more efficient with block space. As of October 2020, the Bech32 address format is supported in many popular wallets and is the preferred address scheme.
See the page Bech32 adoption to track adoption.
=== Examples ===
Examples of the address format being used on mainnet are the TXIDs 4ef47f6eb681d5d9fa2f7e16336cd629303c635e8da51e425b76088be9c8744c and 514a33f1d46179b89e1fea7bbb07b682ab14083a276979f91038369d1a8d689b. And addresses bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq and bc1qc7slrfxkknqcq2jevvvkdgvrt8080852dfjewde450xdlk4ugp7szw5tk9.
== Creating a Bech32 address ==
A Bech32 address is created from a public key as follows:
1. Having a compressed public key (0x02 or 0x03 followed by 32 byte X coordinate):
0279be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798
2. Perform SHA-256 hashing on the public key:
0f715baf5d4c2ed329785cef29e562f73488c8a2bb9dbc5700b361d54b9b0554
3. Perform RIPEMD-160 hashing on the result of SHA-256:
751e76e8199196d454941c45d1b3a323f1433bd6
4. The result of step 3 is an array of 8-bit unsigned integers (base 2^8=256) and Bech32 encoding converts this to an array of 5-bit unsigned integers (base 2^5=32) so we “squash” the bytes to get:
in hex:
0e140f070d1a001912060b0d081504140311021d030c1d03040f1814060e1e16
in numbers:
14 20 15 07 13 26 00 25 18 06 11 13 08 21 04 20 03 17 02 29 03 12 29 03 04 15 24 20 06 14 30 22
5 bits binary:
01110 10100 01111 00111 01101 11010 00000 11001 10010 00110 01011 01101 01000 10101 00100 10100 00011 10001 00010 11101 00011 01100 11101 00011 00100 01111 11000 10100 00110 01110 11110 10110
5. Add the witness version byte in front of the step 4 result (current version is 0):
000e140f070d1a001912060b0d081504140311021d030c1d03040f1814060e1e16
6. Compute the checksum by using the data from step 5 and the H.R.P (bc for MainNet and tb for TestNet)
0c0709110b15
7. Append the checksum to result of step 5 (we now have an array of 5-bit integers):
000e140f070d1a001912060b0d081504140311021d030c1d03040f1814060e1e160c0709110b15
8. Map each value to its corresponding character in Bech32Chars (qpzry9x8gf2tvdw0s3jn54khce6mua7l) 00 -> q, 0e -> w,…
qw508d6qejxtdg4y5r3zarvary0c5xw7kv8f3t4
9. A Bech32_encoded address consists of 3 parts: HRP + Separator + Data:
bc1qw508d6qejxtdg4y5r3zarvary0c5xw7kv8f3t4
The final result from step 9 is the same as example in BIP173.

Betcoin.co Pool

Betcoin.co Pool, also sometimes referred to 'Somebadger's pool', is a mining pool.
Betcoin's Mining Pool uses an anti cheating scoring system.
Older shares (from beginning of the round) have a lower weight than newer shares, which serves to demotivate a cheater from switching between pools inside a round.
Balances accumulate on the server, and are sent out when a user-set threshold balance is reached or the user or manually requested.
There is a fee of 1% for the 1st block and this will be awarded to the person who finds that block.

Bets of Bitcoin

Bets of Bitcoin is a prediction market where users can bet on the outcome of future real world events.
Bet results are decided by the site moderators. The winners will get their wagers back plus will earn the wagers from those that lost (less a small commission paid to the site).
The returns will vary for the winners though as bets are time-weighted and there is a premium earned for those who place their wagers earlier versus those place a bet later.
Anyone can create a bet statement, though new bets are vetted to eliminate bets whose outcome can't be easily determined or is easily manipulated and for bets that the site moderators would rather not see listed. The site pays half of the commission it receives to the person that created the bet statement.
When adding funds to the account with the site (an EWallet), deposits are credited after three confirmationsHow many confirmations.
==History==
The service was launched on August 14, 2011Bets of Bitcoin - Bitcoin betting on real world events. On April 18th, 2012 there was nearly $5,000 USD worth of open bets on the site.
==Criticism==
The site does not offer a profitTop requests on Uservoice or bet payout calculator, and there is no way to recover a forgotten password.
Some betters disagree on the site's decision that a certain betButterfly Labs will not ship ASIC-based Bitforce SC products before April 2013's outcome was too ambiguous to judge.
Others hold a position that the site should be more careful in accepting bets with ambiguous terms in the first place.

BidForCoin

Bid for Coin is a reverse auction bidding site that auctions bitcoins to benefit bitcoin-friendly causes and non-profits. 
The service is located at https://www.bidforcoin.com.
Participants bid small amounts of bitcoin to win larger amounts of bitcoin. The site is distinguished from many Bitcoin gaming sites in that there is no randomizing element. The contests are played by humans against other human opponents in a purely strategic reverse auction game. 
Bid for Coin's style of reverse auction is called a lowest unique bid auction, where bids start at 0.001 BTC and increase in increments of 0.0002 BTC. Participants purchase these bids in secret, and the lowest bid that was purchased by exactly one player wins.
After the total of all purchased bids exceeds the prize amount, the prize is awarded to the lowest unique bidder, and the remainder is split evenly between the site operator and a specified cause or non-profit. 
Currently, these beneficiaries include the Bitcoin Foundation, the Free Software Foundation, and the Internet Archive. 
Any Bitcoin-accepting non-profit can create auctions with a valid Bitcoin payment address.

Binance

Binance is the world's largest cryptocurrency trading platform (exchange) by daily trading volume, with over 350 cryptocurrencies and tokens, surpassing competitors such as Coinbase and Kraken. It offers a wide range of financial services related to cryptocurrencies worldwide, with support for 18 different fiat currencies.
== History ==
Binance was founded in 2017 in China by Changpeng Zhao, who had previously founded Fusion Systems in Shanghai in 2005. The company developed trading systems for brokers. In 2013, Zhao joined Blockchain.info's cryptocurrency wallet team. He also worked at OKCoin as CTO, a platform for spot trading between digital assets and fiat.
In 2017, Binance moved its servers and headquarters from China to Japan ahead of the Chinese government's ban on cryptocurrency trading. A year later, in March 2018, the company had established offices in Taiwan. It is currently headquartered in the Cayman Islands, on Mahé Island, Seychelles.
Over the years, Binance has faced legal challenges in various countries. In 2021, Binance came under investigation by the United States Department of Justice and the Internal Revenue Service for allegations of money laundering and tax crimes. Additionally, in June 2021, in the United Kingdom, the Financial Conduct Authority ordered Binance to halt all regulated activities in the territory.
Binance announced that it would cease support for its BUSD stablecoin starting on December 15, 2023. The New York Department of Financial Services (NYDFS) ordered Paxos, the issuer of BUSD, to stop minting new BUSD tokens due to regulatory concerns. It follows allegations by the U.S. Securities and Exchange Commission (SEC) that BUSD might be an unregistered security.Binance Encourages Users to Convert BUSD to Other Stablecoins Prior to February 2024 | Binance Support

==API==
Bisq offers a trading API
==Features and Philosophy==
Unlike traditional online exchanges, Bisq is designed to be:
*Instantly accessible – no need for registration or approval from a central authority.
*Decentralized – there is no single point of failure. The system is peer-to-peer and trading can not be stopped or censored.
*Safe – Bisq never holds your funds. Decentralized arbitration system and security deposits protect traders.
*Private – no one except trading partners exchange personally identifying data. All personal data is stored locally.
*Secure – end-to-end encrypted communication routed over Tor.
*Open – every aspect of the project is transparent. The code is open source.
*Easy – we take usability seriously.
Bisq is for those who do not want to forfeit control or privacy to a central authority in order to trade with other individuals. We regard financial transactions as a form of private speech that should be protected from surveillance by banks, governments, and other institutions.
==DAO==
Bisq is a distributed open source project with no company or institution in control. Decisions are made via a DAO in which users and contributors vote with BSQ tokens on major decisions.
== Atomic swaps ==
Bisq has pioneered Bitcoin based atomic swaps. It is currently possible to exchange Bitcoin to BSQ atomically. BSQ is Bisq's native token built as a Bitcoin coloured coin.
The atomic swap protocol used by the Bisq DEX goes one step further in reducing counterparty risk: not only are users not exposed to exchange counterparty risk (since DEX holds no user funds) but it also eliminates the possibility of a buyer or seller failing to pay. The transaction is instant, automatic and final (once confirmed in a Bitcoin blockchain block).

BitBargain

BitBargain is a marketplace for bitcoin sales in the United Kingdom that facilitates fast and secure GBP to bitcoin transactions using instant payment methods such as bank transfers, Pingit or Ukash.
===Offers===
Sellers create offers. An offer includes an item (Bitcoin), a payment method (bank transfer, Pingit, Ukash) and some other settings (minimum, maximum amount per transaction, price formula, trust).
===Buying process===
No direct communication is established between buyer and seller. The buyer makes a request and the seller has a very short time to accept it (100 seconds currently). The buyer then gets the details necessary to make the payment. After receiving the payment, the seller releases the buyer's coins which are immediately moved to the buyer's BitBargain wallet, ready to be sent to any bitcoin address.
===Trade speed===
Countdowns, sound alerts and SMS notifications speed up the trade.
