Key facts
- Bitcoin Improvement Proposal 110 entered mandatory signaling at block 961,632.
- Miner support for BIP-110 is currently at 2.53%.
Bitcoin Improvement Proposal 110 has entered its mandatory signaling phase at block 961,632, but miner support is below 3%, far from the 55% threshold. This development raises concerns about a potential fork, with developers warning that Bitcoin holders could lose BTC through replay attacks if they sell new coins. To mitigate risks, users are advised to avoid transactions until early September.

Bitcoin Improvement Proposal 110 (BIP-110) has entered its mandatory signaling phase, beginning at block 961,632. However, miner support for the proposal is significantly low, with only 2.53% of blocks signaling in favor. This figure falls far short of the 55% threshold typically required for such proposals to proceed smoothly. Proponents are now advocating for a user-activated soft fork (UASF) as an alternative path to implementation.
The low miner adoption has heightened concerns about a potential Bitcoin fork related to BIP-110. Developers are warning that Bitcoin holders face the risk of losing actual BTC if they engage in transactions involving new coins generated during a fork. This risk stems from potential replay attacks, where a transaction valid on one chain could be replayed on another, leading to unintended coin transfers. To safeguard their holdings, developers are advising Bitcoin users to refrain from conducting any transactions until early September, a period suggested for increased safety.
The situation highlights a common tension in Bitcoin's development between miner consensus and user or developer-driven changes. BIP-110, if implemented, would introduce specific changes to the network, but the lack of miner buy-in suggests a divergence in priorities or a lack of perceived necessity for the upgrade among a significant portion of the mining community. The push for a UASF indicates that a segment of the community is willing to bypass miner consensus if sufficient user support can be garnered.
Further developments are expected as the signaling period continues, though the current low support suggests a challenging path for BIP-110. The advice to avoid transactions until early September implies that the potential for a fork and subsequent replay attacks is considered a near-term and serious threat by some within the development community.
