  "account": "Bitcoin Improvement Proposal 110, known as BIP-110, is currently in the mandatory-signaling phase with miner support at just 2.53%, far below the 55% threshold required for early activation. The proposal, written by developer Dathon Ohm, aims to restrict transaction outputs and increase transaction fees by limiting output script sizes, OP_RETURN outputs, data pushes, and Taproot features. Nodes enforcing BIP-110 will start rejecting blocks that don't signal support as of block 961,632. While a minority branch has emerged, it quickly lagged behind the dominant chain and has little mining support, making a sustained rival chain unlikely. Supporters argue the restrictions would discourage non-monetary data, while critics, including Michael Saylor and Adam Back, warn the proposal could divide Bitcoin and cause nodes to reject transactions under existing rules. A more extensive fallback has been discussed, but no activation date has been set.",
  "summary": "Bitcoin Improvement Proposal 110 (BIP-110) has entered its mandatory-signaling phase, with miners signaling support in only 51 of the preceding 2,016 blocks, or 2.53%. This is well below the 55% threshold required for early activation, according to the BIP-110 monitor. The proposal, which aims to limit the size of output scripts and OP_RETURN outputs, as well as restrict certain data pushes and witness elements, is being tested to see if enforcing nodes can sustain the change amid limited miner signaling. The low signaling rate makes a sustained rival chain unlikely without substantially greater miner participation.",
