Bitcoin Forks

Bitcoin’s development has included several important upgrades known as forks. These forks can be categorized as soft forks or hard forks:

Soft Forks

Soft forks are updates that are compatible with older versions of Bitcoin software. They make changes without splitting the blockchain into different versions. Some key soft forks include:

  • Segregated Witness (SegWit): Activated in August 2017, SegWit increased Bitcoin’s transaction capacity by separating transaction signatures from transaction data. This change helped reduce transaction fees and improve scalability.
  • BIP 66: Implemented in 2015, BIP 66 introduced stricter rules for transaction signatures to ensure they follow the correct format, improving security and reducing the risk of certain types of attacks.

Hard Forks

Hard forks are major changes that are not backward-compatible, resulting in a split in the blockchain. This creates a new version of Bitcoin that differs from the original. Notable hard forks include:

  • Bitcoin Cash: Created in August 2017, Bitcoin Cash increased the block size limit from 1 MB to 8 MB to allow for more transactions per block. This fork was intended to address scalability issues.
  • Bitcoin SV (Satoshi Vision): Launched in November 2018, Bitcoin SV resulted from a split from Bitcoin Cash. It further increased the block size limit and aimed to restore Bitcoin to what its proponents believe was Satoshi Nakamoto’s original vision.
  • Bitcoin Gold: Introduced in October 2017, Bitcoin Gold was a hard fork designed to make Bitcoin mining more accessible by changing the proof-of-work algorithm from SHA-256 to Equihash. This aimed to allow more people to mine Bitcoin using regular computer hardware.

Technological Changes

Bitcoin has undergone several important technological updates:

  • Lightning Network: Launched in early 2018, the Lightning Network is a technology designed to make Bitcoin transactions faster and cheaper. It operates on top of the main Bitcoin blockchain, allowing for quick transactions between users without congesting the main network.
  • Taproot Upgrade: Rolled out in November 2021, Taproot enhanced Bitcoin’s privacy and efficiency. It introduced more flexible and efficient scripts, improving Bitcoin’s smart contract capabilities and overall network performance.
