Nodes enforcing BIP-110 split from Bitcoin's main chain at block 961,632 on Saturday, rejecting the first non-signalling block — a one-sided defection that immediately stalled, the minority chain producing two blocks while the main chain added dozens. Foundry's customer vote resolved No, with non-responses counted against and support never near its 51% bar. Ledger and developers warned the fork carries no replay protection: transactions can be copied across chains, so claiming fork coins risks moving mainnet BTC. Update, Aug 9: fork remains frozen at two blocks — ~0.15% of hashrate enforces it, meaning most signalers aren't mining it, and a first difficulty adjustment would take decades"

BTCPay Server confirmed attackers stole funds from merchant Lightning nodes through the critical flaw patched Friday, with Foundation and Citadel21 among named victims, per multiple outlets. The exploit captured node credentials on servers running outdated versions rather than breaking any cryptography; operators were again urged to update, rotate credentials and move hot-wallet funds. Some coverage framed the incident as part of a broader wave of exploits hitting Bitcoin infrastructure projects.
