Capacity improvements. 5 proposals.
- BIP 102: Block size increase to 2MB: Closed. Proposed a single, simple increase in the maximum block size from 1 MB to 2 MB to allow more transactions per block. Being a change that older software would reject, it would have required a hard…
- BIP 103: Block size following technological growth: Closed. Proposed gradually increasing the block size limit at a rate meant to track improvements in hardware and internet bandwidth. The goal was to allow more transactions while keeping it practical for…
- BIP 105: Consensus based block size retargeting algorithm: Closed. Proposed a mechanism for changing the maximum block size based on votes or consensus among network participants rather than a fixed number. It aimed to let the limit adapt over time without repeated…
- BIP 109: Two million byte size limit with sigop and sighash limits: Closed. Proposed doubling the block size limit from 1 MB to 2 MB, alongside new caps on signature checks and data hashing to stop specially crafted blocks from overloading nodes. It was associated with the…
- BIP 141 (SegWit): Segregated Witness (Consensus layer): Deployed. Defines Segregated Witness (SegWit), which moves signatures into a separate "witness" section of each transaction while remaining compatible with older nodes. This fixed transaction malleability,…
