Eclair, ACINQ’s Lightning node software program, has merged two repairs for gaps that could make a node lose Bitcoin via extreme mining fees throughout channel funding and splicing. One limits a peer’s fee-bump calls for when Eclair contributes funds; the opposite checks transactions from a compromised Bitcoin backend whereas Eclair retains the signing keys. The…
Lightning Development Kit (LDK), a library for constructing Bitcoin Lightning wallets and fee purposes, has patched a flaw that would let a malicious channel peer steal the worth of a forwarded fee by mendacity after reconnecting. Affected utility builders want to include the repair into the software program they deploy. The October 1-dated v0.2.7 and…
Core Lightning, software program for operating Bitcoin Lightning payment nodes, has launched v26.06.9 with security fixes and a restore for a regression that might delay channel visitors on busy nodes operating v26.06.8. GitHub lists the new release as revealed Oct. 7, whereas its versioned changelog carries an Oct. 6 date. The replace provides operators who…
A newly disclosed unfunded-channel flaw could depart Eclair, a Bitcoin Lightning implementation, crashing repeatedly with out an attacker spending BTC on-chain. The flaw affected reachable nodes operating v0.14.0 and earlier, with saved channel data making a restart inadequate to revive service. Researcher Erick Cestari printed the persistent-crash finding Sept. 30 and defined it alongside a…
Electrum’s newest safety replace fixes a Lightning backup defect, but some Bitcoin pockets customers nonetheless want to switch saved backups. Older backups from wallets with non-deterministic Lightning keys lack data wanted to reclaim funds from anchor channels, a Lightning channel kind, after a distant shut. Version 4.8.2, dated Sept. 11, stays the newest launch listed…
Core Lightning, a Lightning Network node implementation, mounted a channel-close flaw in v26.06.7 that could let a peer broadcast an previous, revoked channel state with out triggering the penalty for dishonest. Bitcoin Optech’s Sept. 25 explanation of the now-public patch makes the chance concrete for operators nonetheless operating older builds. Related Reading Onslaught of AI-found…
Even if Bitcoin ultimately adopts post-quantum protections for on-chain outputs, 5 components of the Lightning Network’s off-chain cost system would nonetheless want separate upgrades, in line with a Sept. 12 research preprint. Related Reading Bitcoin exchanges can reduce quantum exposure before a network upgrade The paper proposes PQLN, a hybrid post-quantum extension applied as a…
Lightning Development Kit, a toolkit for constructing Bitcoin Lightning purposes, launched v0.2.6 on Sept. 9 with fixes for bugs that would divert small quantities of a node’s funds or stop saved channel state from loading. LDK packages a Lightning implementation as a software program improvement package for makes use of together with cellular wallets and…
Bitcoin’s Lightning Network capacity has declined from over 5,400 BTC in late 2023 to around 4,200 BTC by August 2025, a roughly 20% drop, per mempool.space data. While the raw figures imply a contraction, analysts and developers suggest the shift reflects structural evolution in routing and protocol design rather than a retreat in adoption. Lightning…
