Bitcoin Optech: Eclair Fix & Node Feerate Analysis
Bitcoin Optech reports a critical Eclair vulnerability and a comprehensive scan of full node fee settings. The disclosed flaw in older Eclair versions allowed attackers to broadcast outdated commitment transactions and steal channel funds. Users should upgrade to Eclair v0.12+ immediately. Additionally, the fee-filter study of 30 000 full nodes shows that 88% use the default 1 sat/vB relay rate, 4% adopt the upcoming 0.1 sat/vB default in Bitcoin Core 30.0, and 8% did not respond. A minor subset set a high 10 000 sat/vB filter when syncing behind the chain. This Bitcoin Optech newsletter also covers OP_RETURN policy changes, Bitcoin Core 30.0rc1 release, and updates across Lightning and Bitcoin infrastructure projects.

The Eclair vulnerability was responsibly disclosed and patched in v0.12+, mitigating a direct security threat for channel users. The node fee-filter analysis confirms stable relay policies across the network, reducing unexpected fee spikes. Upcoming Bitcoin Core 30.0 features and OP_RETURN adjustments affect infrastructure maintenance but have limited impact on trading volumes or price movements. Compared to past incidents where unpatched channel flaws or major Core upgrades caused temporary volatility, this news reassures traders of continued network resilience without triggering significant market shifts.
