The bitcoin-ml mailing list is a good venue for making proposals for changes that require coordination across development teams. Workgroups have been set up to assist developers to coordinate and seek peer-review. For those wishing to implement changes to the Bitcoin Cash protocol, it is recommended to seek early peer-review and engage collaboratively with other developers through the workgroups.
Every 2,016 blocks (approximately 14 days at roughly 10 min per block), the difficulty target is adjusted based on the network's recent performance, with the aim of keeping the average time between new blocks at ten minutes. In this way the system automatically adapts to the total amount of mining power on the network.[3]:ch. 8 Between 1 March 2014 and 1 March 2015, the average number of nonces miners had to try before creating a new block increased from 16.4 quintillion to 200.5 quintillion.[80]
Bitcoin (BTC) is a cryptocurrency which is regarded as the world’s first decentralized digital currency. It was created by a pseudonymous person or persons named Satoshi Nakamoto in 2009 and has since gone on to become the world’s most popular cryptocurrency by market cap. Bitcoin is a deflationary currency whose issuance is capped at a total supply of 21 million coins. Each Bitcoin can be divided into one million units, with the smallest unit of 0.00000001 known as a satoshi in homage to its creator. The distributed public ledger that Bitcoin uses to record transactions is known as a blockchain and Bitcoin can be spent at over 100,000 online merchants and can also be held as an investment. Bitcoin is traded for fiat and other cryptocurrencies on various exchanges but can also be used to facilitate p2p transactions. Each transaction incurs a small transaction fee to cover the cost of sending Bitcoin over the blockchain ledger, with the fee going to miners tasked with keeping the network secure.

In December 2013, Overstock.com[87] announced plans to accept bitcoin in the second half of 2014. On 5 December 2013, the People's Bank of China prohibited Chinese financial institutions from using bitcoins.[88] After the announcement, the value of bitcoins dropped,[89] and Baidu no longer accepted bitcoins for certain services.[90] Buying real-world goods with any virtual currency had been illegal in China since at least 2009.[91]

On 24 August 2017 (at block 481,824), Segregated Witness (SegWit) went live. Transactions contain some data which is only used to verify the transaction, and does not otherwise effect the movement of coins. SegWit introduced a new transaction format that moved this data into a new field in a backwards-compatible way. The segregated data, the so-called witness, is not sent to non-SegWit nodes and therefore does not form part of the blockchain as seen by legacy nodes. This lowers the size of the average transaction in such nodes' view, thereby increasing the block size without incurring the hard fork implied by other proposals for block size increases. Thus, per computer scientist Jochen Hoenicke, the actual block capacity depends on the ratio of SegWit transactions in the block, and on the ratio of signature data. Based on his estimate, if the ratio of SegWit transactions is 50%, the block capacity may be 1.25 megabytes. According to Hoenicke, if native SegWit addresses from Bitcoin Core version 0.16.0 are used, and SegWit adoption reaches 90% to 95%, a block size of up to 1.8 megabytes is possible.[citation needed]
Google Trends structures the chart to represent a relative search interest to the highest points in the chart. A value of 100 is the peak popularity for the term “Bitcoin” and a value of 50 means it was half as popular at that time. A score of 0 indicates that the term was less than 1% as popular as the peak. It’s amazing how the searches relating to Bitcoin have spiked in the past few years.
In the blockchain, bitcoins are registered to bitcoin addresses. Creating a bitcoin address requires nothing more than picking a random valid private key and computing the corresponding bitcoin address. This computation can be done in a split second. But the reverse, computing the private key of a given bitcoin address, is mathematically unfeasible. Users can tell others or make public a bitcoin address without compromising its corresponding private key. Moreover, the number of valid private keys is so vast that it is extremely unlikely someone will compute a key-pair that is already in use and has funds. The vast number of valid private keys makes it unfeasible that brute force could be used to compromise a private key. To be able to spend their bitcoins, the owner must know the corresponding private key and digitally sign the transaction. The network verifies the signature using the public key.[3]:ch. 5
Bitcoin is one of the first digital currencies to use peer-to-peer technology to facilitate instant payments. The independent individuals and companies who own the governing computing power and participate in the Bitcoin network, also known as "miners," are motivated by rewards (the release of new bitcoin) and transaction fees paid in bitcoin. These miners can be thought of as the decentralized authority enforcing the credibility of the Bitcoin network. New bitcoin is being released to the miners at a fixed, but periodically declining rate, such that the total supply of bitcoins approaches 21 million. One bitcoin is divisible to eight decimal places (100 millionth of one bitcoin), and this smallest unit is referred to as a Satoshi. If necessary, and if the participating miners accept the change, Bitcoin could eventually be made divisible to even more decimal places.

Bitcoin's origin story sounds like something out of science fiction: It was launched in 2008 on the heels of a white paper published by the mysterious Satoshi Nakamoto, whose real identity – and country of origin – are unknown. Nakamoto conceived of Bitcoin as a currency that was 1) encrypted; 2) decentralized, i.e. it was ungoverned and did not belong to any nation; and 3) a digital "distributed ledger," such that everyone can verify online the legitimacy of transactions.
Illiquidity. This is mostly moot due to Bitcoin’s $47 market cap but it still makes users sweat. It’s highly unlikely that Bitcoin’s price would plummet and you’d be unable to take action, but it’s still unsettling.  As more investors invest, however, illiquidity becomes a negligible risk, as there will likely always be a buyer for Bitcoins waiting.
The domain name "bitcoin.org" was registered on 18 August 2008.[15] In November 2008, a link to a paper authored by Satoshi Nakamoto titled Bitcoin: A Peer-to-Peer Electronic Cash System[5] was posted to a cryptography mailing list. Nakamoto implemented the bitcoin software as open source code and released it in January 2009.[16][17][10] Nakamoto's identity remains unknown.[9]
