Bitcoin Unlimited is an attempt to upgrade Bitcoin Core into a client that processes bitcoin transactions into blocks with a potential maximum size greater than the Core's hard-coded limit of one megabyte. The one megabyte block size limit was added in 2010 by Satoshi Nakamoto as a temporary anti- DoS measure.

The following are forks of the software client for the bitcoin network: Bitcoin XT 1. A fork initiated by Mike Hearn. The current reference implementation for bitcoin contains a computational bottleneck. The actual fork was preceded by Mike Hearn publishing a Bitcoin Improvement Proposal (BIP 64) on June 10, 2014, calling for the addition of "a sma...
Hard forks splitting bitcoin (aka "split coins") are created via changes of the blockchain rules and sharing a transaction history with bitcoin up to a certain time and date. The first hard fork splitting bitcoin happened on 1 August 2017, resulting in the creation of Bitcoin Cash. The following is a list of notable hard forks splitting bitcoin by ...
The fork fixing the value overflow incident was controversial because it was announced after the exploit was mined. It was assigned CVE-2010-5139.
Taproot
Taproot is an agreed soft fork in the transaction format. The fork adds support for Schnorr signatures, and improves functionality of smart contracts and the Lightning Network. The fork was installed in November 2021. The upgrade adds privacy features.Taproot includes Bitcoin Improvement Proposal numbers BIP340, BIP341, BIP342. Advantages: 1. Complex transactions, such as those requiring multiple signatures or those with delayed release, are indistinguishable from simple transactions in terms...
Two hard forks were created by "protocol change" definition: 1. March 2013 Chain Fork (migration from BerkeleyDB to LevelDB caused a chain split) 2. CVE-2018-17144 (Bitcoin 0.15 allowed double spending certain inputs in the same block. Not exploited)
Bitcoin XT, Bitcoin Classic and Bitcoin Unlimited each supported an increase to the maximum block size. On 1 August 2017, the day when BTC forked, the BTC blockchain split into two separate blockchains: one maintained in accordance with the rules currently valid for Bitcoin, and the other maintained in accordance with the rules ...
Bitcoin is a cryptocurrency, a digital asset that uses cryptography to control its creation and management rather than relying on central authorities. [1] . Originally designed as a medium of exchange, Bitcoin is now primarily regarded as a store of value.
Nakamoto owns between 750,000 and 1,100,000 Bitcoin. [needs update] In November 2021, when Bitcoin reached a value of over $68,000, his net worth would have been up to $73 billion, making him the 15th-richest person in the world at the time.
A diagram of a bitcoin transfer. The Bitcoin protocol is the set of rules that govern the functioning of Bitcoin. Its key components and principles are: a peer-to-peer decentralized network with no central oversight; the blockchain technology, a public ledger that records all Bitcoin transactions; mining and proof of work, the process to create ...
