Michael Saylor Says BIP-110 Fork Has Failed to Gain Bitcoin Miner Support

Highlights:

• Michael Saylor says almost all Bitcoin miners rejected the BIP-110 fork, leaving it with only 0.15% hashpower.
• The BIP-110 branch has mined just two blocks and is now more than 80 blocks behind Bitcoin.
• BIP-110 aims to temporarily limit extra data stored on Bitcoin, but it still needs strong miner support.

Michael Saylor says the BIP-110 fork has received very little support from Bitcoin miners. In an August 9 post on X, Saylor said about 99.85% of Bitcoin’s total mining power remained on the main Bitcoin network. In comparison, the BIP-110 branch had mined only two blocks and was already more than 80 blocks behind.

Saylor said the result showed how Bitcoin’s open system works. Anyone can create a new version, or fork, of Bitcoin, but miners and users are not required to support it. According to Saylor, the BIP-110 branch currently has only about 0.15% of Bitcoin’s total hashpower, showing that almost all miners have stayed with the main network.

BIP-110 Fork Struggles with Very Low Hashpower

Hashpower refers to the computing power miners use to process transactions, produce new blocks, and secure the Bitcoin network. A blockchain with very little hashpower can struggle to produce blocks quickly, especially when its mining difficulty was set for a much larger network.

Saylor said the BIP-110 branch still needs to mine another 2,015 blocks before reaching its first difficulty adjustment. Bitcoin normally adjusts mining difficulty every 2,016 blocks to keep block times relatively stable. However, with only around 0.15% of Bitcoin’s hashpower, Saylor estimated that the BIP-110 branch could take about 25 years to reach that adjustment if the current mining rate continues.

“Anyone can fork Bitcoin,” Saylor wrote. He added that a fork without enough security, utility, capital, and users has little value. “Consensus is earned, not declared,” he said.

At ~0.15% of Bitcoin's hashpower, BIP-110 must mine 2,015 more blocks before its first difficulty adjustment. At today's rate, that is ~25 years. Anyone can fork Bitcoin. Without security, utility, capital, and users, a fork is irrelevant. Consensus is earned, not declared.

What Is BIP-110?

BIP-110, called the Reduced Data Temporary Softfork, was first drafted on October 24 last year, and was officially assigned as BIP-110 on December 3. The proposal aims to temporarily limit how much non-payment data users can place on the Bitcoin blockchain. In other words, it would restrict some ways people use Bitcoin transactions to store extra data instead of simply sending Bitcoin.

One part of BIP-110 would limit OP_RETURN outputs to 83 bytes. OP_RETURN is a feature that allows users to add small amounts of data to a Bitcoin transaction. The proposal also sets limits on several other methods of adding larger amounts of data to the network. These rules would apply temporarily rather than becoming permanent changes.

For activation, BIP-110 uses a modified version of BIP9, a system that allows Bitcoin miners to signal support for proposed network changes. The proposal requires support from 55% of miners during a signaling period. It also sets a maximum activation height of 965,664, expected around September 1. If the proposal activates, its additional rules would remain in place for about one year before expiring.

Saylor Points to Bitcoin Network Consensus

Saylor’s main point was not about whether BIP-110 is technically useful. Instead, he focused on how little miner support the separate branch has attracted. Based on the figures he shared, almost all Bitcoin miners have stayed on the main Bitcoin network. The situation also shows how difficult it is for a Bitcoin fork to gain real traction. A new branch needs more than software rules. It also needs miners, users, capital, infrastructure, and market support.
