History
- 2009-01-03: Bitcoin launched with the mining of the genesis block (i.e. block number 0).
- 2012-11-28: Bitcoin reward halved from 50 BTC to 25 BTC at block number 210 000.
- 2016-07-09: Bitcoin reward halved from 25 BTC to 12.5 BTC at block number 420 000.
- 2017: The BIP 148 UASF movement occurred to oppose a takeover by merchants and miners of the Bitcoin blockchain.[1].
- 2017-04-05: Gregory Maxwell publishes an analysis suggesting BitMain halted adoption of SegWit due to the soft fork's incompatibility with the ASICBoost mining technique that exploits how SHA-256 hashing is implemented when mining block headers.[2] [3]
- 2017-12-16: Bitcoin price hits a local maximum of about 19 000 USD/BTC
- 2018-12-10: Bitcoin price hits a local minimum of about 3 400 USD/BTC
- 2020-05-11: Bitcoin reward halved from 12.5 BTC to 6.25 BTC at block number 630 000.
- 2021-11-09: Bitcoin price hits a local maximum of about 68 000 USD/BTC.
- 2022-11-22: Bitcoin price hits a local minimum of about 15 480 USD/BTC, coinciding with the collapse of FTX.
- 2024-01-09: A short-term price spike occurred due to a false announcement by a compromised SEC Twitter account post regarding a decision on whether Bitcoin ETFs are allowed. The decision was expected to be published on 2024-01-10.[4]

Accessed 2023-11-11. “The general idea of this attack is that SHA2-256 is a merkle damgard hash function which consumes 64 bytes of data at a time. ¶ The Bitcoin mining process repeatedly hashes an 80-byte 'block header' while incriminating a 32-bit nonce which is at the end of this header data. This means that the processing of the header involves two runs of the compression function run-- one that consumes the first 64 bytes of the header and a second which processes the remaining 16 bytes and padding. ¶ The initial 'message expansion' operations in each step of the SHA2-256 function operate exclusively on that step's 64-bytes of input with no influence from prior data that entered the hash. ¶ Because of this if a miner is able to prepare a block header with multiple distinct first 64-byte chunks but identical 16-byte second chunks they can reuse the computation of the initial expansion for multiple trials. This reduces power consumption.”

We can also confirm that the account did not have two-factor authentication enabled at the time the account was compromised.”.
