Overview
- From block 961,632, expected around Aug. 9, nodes running BIP-110-capable software will begin rejecting blocks that do not signal support, creating a mismatch in which blocks different nodes accept.
- Public miner signaling for BIP-110 is extremely low at roughly 2.6%, far below the 55% (1,109 of 2,016) threshold needed to lock in the upgrade via miner support.
- Because the proposal does not enable its reduced-data rules until block 965,664 in early September, any split before then would lack automatic replay protection and signed transactions could move coins on both chains.
- Developers warn that selling coins from a possible minority BIP-110 chain could let buyers replay those transactions on the main chain and drain the seller’s real BTC, so non-experts are advised not to move funds.
- The fork’s outcome depends on economic coordination among miners, exchanges, wallets and large holders; some bitcoin-only exchanges are preparing temporary deposit and withdrawal pauses as a precaution.
