Bitcoin Enchancment Proposal 110 entered its mandatory-signaling section at block 961,632 on Saturday, with miners signaling assist in simply 51 of the previous 2,016 blocks, or 2.53%, effectively under the 55% threshold required for early activation, in accordance with the BIP-110 monitor.
Beginning at block 961,632, nodes imposing BIP-110 started rejecting blocks that didn’t set model bit 4, whereas odd Bitcoin nodes continued accepting each signaling and non-signaling blocks. A minority BIP-110 department subsequently emerged, however shortly fell behind the dominant chain.
The low signaling fee makes a sustained rival chain unlikely with out considerably higher miner participation. With comparatively little mining assist, a BIP-110 department may advance slowly or cease producing blocks altogether.
The milestone exams whether or not supporters can advance a contentious consensus change with out broad miner backing, probably separating imposing nodes from the dominant chain and escalating a dispute over how Bitcoin’s block area needs to be used.
BIP-110 seeks non permanent limits on Bitcoin knowledge
Written by pseudonymous developer Dathon Ohm, BIP-110 proposes further consensus restrictions lasting roughly one yr.
It could restrict most new output scripts to 34 bytes, cap OP_RETURN outputs at 83 bytes, limit sure knowledge pushes and witness parts to 256 bytes, and quickly restrict a number of Taproot options. Unspent transaction outputs created earlier than activation can be exempt.
Supporters stated the restrictions would discourage inscriptions and different non-monetary knowledge that improve storage and bandwidth prices for node operators.
The proposal’s critics, together with Technique Government Chairman Michael Saylor and Blockstream CEO Adam Again, have argued that the proposal may divide Bitcoin and trigger nodes to reject transactions permitted beneath the community’s current guidelines.
The proposal makes use of model bit 4 for miner signaling. Its deployment schedule units blocks 961,632 by means of 963,647 as a mandatory-signaling window, throughout which nodes imposing BIP-110 reject blocks that don’t carry the sign.
The specification defines block 963,648 as the start of its locked-in state and block 965,664 as the purpose when its transaction restrictions take impact.
BIP-110 proponents have additionally mentioned a extra in depth fallback. On Aug. 1, Bitcoin developer Chris Guida rebased preliminary code for a proof-of-work change initially written by Bitcoin Knots maintainer Luke Dashjr.
Guida described the code on the time as a contingency if miners opposed BIP-110, however stated no activation date had been set.
