(Winston Chen/Unsplash)SummaryShow- A miner utilizing Ocean's DATUM protocol opted not to signal support for the contentious BIP-110 fork, proceeding to mine block 961,634 on the main bitcoin chain.
- Simple Mining's choice highlighted that BIP-110 garnered merely 2.6% of hashrate support, significantly below the 55% threshold required to limit non-financial data in transactions for a year.
- Following the rejection of non-signaling blocks at height 961,632, the forked chain managed to produce only two blocks before stalling, while the primary bitcoin chain advanced over 200 blocks ahead.
A bitcoin miner decided against supporting BIP-110 on Sunday, leveraging a tool from its mining pool that allowed it to decide the contents of its block independently.
Simple Mining announced that it successfully mined block 961,634 on the main chain, surpassing the point where supporters of BIP-110 split off.
"Hashrate is a vote you cannot fake, and we determined the proposal wasn't worth pursuing," Simple Mining conveyed on X.

The block did not signal support for BIP-110.
Support peaked at 2.6% while the proposal needed 55%.

This decision is noteworthy as Ocean, the mining pool utilized, had switched to signaling for BIP-110 by default in July and was responsible for nearly all of the limited support for the proposal prior to the split.
BIP-110, or Bitcoin Improvement Proposal-110, aims to prevent the storage of images, text, and other non-financial data within bitcoin transactions for a year.
Simple Mining's ability to diverge from the pool's default stance was facilitated by its use of DATUM, a protocol from Ocean that grants miners autonomy over the blocks they create.
Mining pools generally aggregate the computational power of multiple operators to discover blocks more frequently and share the rewards. Typically, the pool dictates which transactions are included in the blocks and what signals they convey.
DATUM shifts that decision-making authority back to individual miners. An operator can assemble its own block using personalized bitcoin software while still contributing computational power to Ocean and enjoying the pool's rewards.
Simple Mining exercised that authority to exclude the BIP-110 signal from block 961,634.
"We opted not to signal, and the chain continued on our block," the company stated.
This also clarifies why Ocean has appeared on both sides of the split over the weekend.
A miner affiliated with Ocean mined the first block accepted by the BIP-110 branch on Saturday, according to fork tracker Mempool. Subsequently, Simple Mining, using the same pool, made a contrasting choice, producing a block for the prevailing bitcoin chain.
Computers running BIP-110 software began to reject blocks that lacked its signal at block 961,632, after miner support peaked at around 2.6%, which is significantly lower than the required 55%.
The minority branch has faced difficulties since, managing to produce blocks 961,632 and 961,633 before stalling, while bitcoin continued to generate blocks roughly every ten minutes.
By Monday, a live tracker reported the main chain at block 961,725, leaving the BIP-110 branch trailing by over 200 blocks.
