The leaders of the BIP-110 initiative withdrew the rule change after a vulnerability was discovered in the Coldcard wallet.

In any case, the change could not have been adopted, as miner support stood at only 2.53% .

Node operators were advised to roll back to the previous version, up to block No. 961,632.

The developers who had been promoting the BIP-110 rule change on the Bitcoin network have canceled its implementation. They attributed this to the industrys reaction to a security breach in the Coldcard wallet, which made it easier to steal users funds.

Udi Wertheimer announced the postponement, urging everyone using BIP-110 software to revert to the standard Bitcoin (BTC) node. He did not specify a new date.

BIP-110 is a temporary rule change known as a soft fork. It would have limited the amount of data users can include in Bitcoin transactions.

Supporters argue that excess data is crowding out regular transactions. Critics believe that Bitcoin should not regulate what its users store. LINE_BREAK The restrictions would remain in effect for one year. The rules were developed by participant Daton Ohm, and their implementation is handled by the Bitcoin Knots software.

Miners began voting on December 1, 2025. Debates over spam in Bitcoin blocks have already divided the community.

Later, another problem arose.

On July 30, Coinkite disclosed details about a bug. Its COLDCARD wallets generated seed phrasesthe master key underlying the walletwith much less randomness than promised. Approximately 72 bits instead of 128.

This difference makes it significantly easier to guess the seed phrase. Wallets running firmware released since March 2021 were found to be the most vulnerable.

Updating the device does not fix a seed phrase that has already been generated. Coinkite advises owners to withdraw their funds.

Attackers have already emptied wallets linked to this vulnerability. The company did not disclose the amount of the losses.

Wertheimer described the delay as a matter of timing, not doubt.

in light of the Coldcard incident, the BIP-110 community leaders have decided to POSTPONE ACTIVATION. A new activation date will be announced later, he wrote.

Miners support the rule change by marking their blocks with the corresponding flag. Adoption of BIP-110 required 55% of blocks over a two-week period. This is equivalent to 1,109 blocks. The real-time monitor counted 30.”,”detected_source_language”:”RU
