A draft BIP would standardise which Bitcoin outputs expose their keys
Published estimates of quantum-exposed supply range from about 25% to over 34%. The author argues the gap is definitional and proposes four levels with a fail-closed rule.

Eclair 0.14 fixes two bugs that let any peer knock a node offline
One came from parsing feature bits one at a time, the other from zlib channel queries BOLT 7 retired four years ago. A fuzzer found the first, AI-assisted variant analysis the second.
Open challenge cuts GPU cost of a quantum-safe bitcoin spend to about $67
One week of public optimisation took the QSB construction from roughly $320 to an estimated $67 in compute. StarkWare still calls a soft fork the better long-term answer.
A post-quantum Lightning proposal would cost nodes ten times the bandwidth
PQLN adds ML-DSA and ML-KEM to Lightning's gossip, transport, invoices and onions without a consensus change. The on-chain parts stay classical, and the author names bandwidth as the real price.
BIP-375's DLEQ challenge was not reduced modulo the group order
A three-line change to bip-0375/deps/dleq.py applies % GE.ORDER to the challenge and adds two lines to proof verification. Small diff, cryptographic surface.
BIP-138 widens its recipient set to every distinct key in the backup payload
The merged change redefines the keys used by the wallet-account backup scheme: distinct public keys across all descriptor and policy sets and all content items, rather than one descriptor's keys.
BIP-371 drops the finalizer clause from a Taproot PSBT field
The per-output description of PSBT_OUT_TAP_BIP32_DERIVATION no longer refers to what a finalizer must do.
A PSBT test vector arrives because a bug got past the old ones
BIP-174 gains a combiner vector for the sighash type, plus an instruction to run the existing vectors in both orders - because Combine is not commutative and the tests were.
BIP-138 encrypts the part of a wallet backup that is not the seed
A new draft BIP defines a compact encryption scheme for output script descriptors, wallet policies and other metadata. The payload is forbidden from containing private key material.
The descriptor BIPs are reclassified from Standard to Specification
A merge into the BIPs repository moves BIP 379 through BIP 390 to the Specification type introduced by the revised BIP process.
