Bitcoin BIP-110 signaling starts with just 2.53% miner support

Bitcoin just tested one of its most contested rule changes yet — and the numbers suggest it isn’t going well for the proposal’s backers. At block 961,632, the network entered mandatory signaling for BIP-110, a soft fork designed to curb non-financial data on the blockchain, but the Bitcoin BIP-110 signaling effort arrived with miner backing stuck below 3%, far short of what it needs to force real change.

Key takeaways

  • BIP-110 entered mandatory signaling at block 961,632 with miner support at just 2.53%, well below the 55% threshold required for activation.
  • Nodes enforcing BIP-110 began rejecting blocks that didn’t signal with version bit 4, splitting a minority chain off from the dominant Bitcoin network.
  • The breakaway chain quickly fell behind the main chain, and low miner participation makes a lasting rival chain unlikely.
  • BIP-110 would impose roughly one year of restrictions on output scripts and certain Taproot features to discourage inscriptions and reduce storage costs for node operators.
  • Critics including Strategy’s Michael Saylor and Blockstream’s Adam Back warn the plan could split Bitcoin and cause valid transactions to be rejected; developers have also prepared fallback proof-of-work code as a contingency.

BIP-110 Begins Mandatory Signaling With Miner Support Under 3%

BIP-110’s mandatory-signaling phase kicked off at block 961,632 on Saturday, following backing from miners across only 51 of the last 2,016 blocks — a 2.53% rate, according to the BIP-110 monitor. That’s nowhere close to the 55% threshold the proposal needs to lock in early. CoinDesk reported that the signaling phase began at around 19:35 UTC that day, with support “seldom exceeding 2.5%.” Crypto Briefing similarly noted that signaling for the proposal has fluctuated between 0.3% and 2.6% in recent periods, with no major mining pool publicly backing it.
