However, the described + protocol is interactive and requires cooperation among all the signers and involves + the presence of an untrusted coordinator to reduce communication complexity. + The coordinator role can be taken by any of the signers participating in the process. + + The process is divided into two rounds: + + 1. Each signer starts the signing session by computing a secret nonce + (`secnonce`) and a public nonce (`pubnonce`). `pubnonce` is sent to the + coordinator, which aggregates them (`aggnonce`) and sends the result back to + signers, together with other pieces of information. + + 2. Each signer computes a partial signature using the secret key, `secnonce`, + the message to sign, and the information provided. Partial signatures are then + sent to the coordinator, which aggregates them in a single 64-byte signature. + + According to Jahr, one of the possible applications of the proposal would + be [cross-input signature aggregation (CISA)][topic cisa], a change to Bitcoin + consensus that would reduce size and thus on-chain fees of multi-input transactions. + However, the author specified that the consensus change is outside the scope of this BIP. + + The draft BIP, which is now referred to as BIP459, is currently being discussed in [BIPs #2210][] + and the proposal is gathering feedback from the community. ## Changes to services and client software @@ -46,4 +73,5 @@ FIXME:Gustavojfe {% include snippets/recap-ad.md when="2026-07-28 16:30" %} {% include references.md %} -{% include linkers/issues.md v=2 issues="" %} +[aggr ml]: https://groups.google.com/g/bitcoindev/c/TF5mPfy58RQ/m/vAk1Mfg2AwAJ +[news351 dahlias]: /en/newsletters/2025/04/25/#interactive-aggregate-signatures-compatible-with-secp256k1 From fb4e4425ab949c4565b5a835f6b0186661c423b8 Mon Sep 17 00:00:00 2001 From: Mike Schmidt Date: Wed, 22 Jul 2026 06:59:54 -0500 Subject: [PATCH 3/5] News415: add client services segment --- .../en/newsletters/2026-07-24-newsletter.md | 49 ++++++++++++++++++- 1 file changed, 48 insertions(+), 1 deletion(-) diff --git a/_posts/en/newsletters/2026-07-24-newsletter.md b/_posts/en/newsletters/2026-07-24-newsletter.md index 70a7e3210..36c0d6033 100644 --- a/_posts/en/newsletters/2026-07-24-newsletter.md +++ b/_posts/en/newsletters/2026-07-24-newsletter.md @@ -48,7 +48,44 @@ and summarizing notable changes to popular Bitcoin infrastructure software. *In this monthly feature, we highlight interesting updates to Bitcoin wallets and services.* -FIXME:bitschmidty +- **Wasabi Wallet 2.8.0 released:** + Wasabi Wallet [2.8.0][wasabi 2.8.0] downloads [compact block filters][topic compact + block filters] directly from the P2P network, removing the previously + required centralized backend server.

The author reports roughly double the hashing throughput in + isolated benchmarks and about a 5% reduction in one chainstate-reindex run. + +- [Bitcoin Core #35766][] enables [BIP324][] [v2 p2p transport][topic v2 p2p + transport] by default when first connecting to addresses from DNS seeds and + the compiled-in fixed seeds. Experimental support for BIP324 shipped in + Bitcoin Core 26.0 and was enabled by default in 27.0. Since these seed + mechanisms provide addresses without service flags, Bitcoin Core previously + treated the peers as v1 only and a node's earliest automatic connections + never attempted encrypted transport.

If this assumption + is incorrect for a given peer, the node simply reconnects using v1. + Connections made through the `-seednode` option and address fetching + already attempt v2 by default. + +- [BIPs #2075][] clarifies [BIP174][]'s description of how [PSBTs][topic psbt] + are combined. The specification had asserted that combining independently + updated PSBTs is unconditionally order-independent, but this only holds when + the participants add distinct fields. When two PSBTs contain the same key + with different values, a combiner may pick either value or refuse to combine, + so the specification now notes that in this case the result is not + commutative. + +- [BIPs #2204][] updates the draft [BIP440][] and [BIP441][] Great Script + Restoration specifications (see [Newsletter #400][news400 gsr]). It + introduces `wordspan` notation, which rounds up the byte length of a stack + element to the next eight-byte boundary, and reworks numerous operation cost + formulas so that operations that process data in 64-bit words are charged by + `wordspan` while those that work on the exact bytes stay costed by `length`. + The update also corrects the definition of `OP_RIGHT` and clarifies costs + and range checks for several other opcodes. + +- [Core Lightning #8935][] fixes a bug that could cause a node to repeatedly + [RBF][topic rbf] a transaction, even after a replacement had already + confirmed. CLN stores pending transactions in an `outgoing_tx_map` keyed by + the original txid, but it replaces the transaction object with each + higher-fee version without changing the key. The per-block + `rebroadcast_txs()` loop checked for confirmation using the stale original + txid, which was never mined, so it kept invoking the rebroadcast and + replacement logic even though the latest transaction had confirmed. Since + the txid serves as the hash-table key and cannot be updated in place, the + loop now computes the current transaction's txid with each iteration and + uses it for confirmation checks. + +- [Core Lightning #9324][] fixes a `Renepay` regression (see [Newsletter + #263][news263 renepay]) present since v26.04 that built [HTLCs][topic htlc] + with CLTV expiries roughly one block height too far in the future. Renepay's + route data already incorporated the current block height into each hop's + CLTV value, but `route_sendpay_request()` added the block height a second + time when passing the route to `sendpay`, roughly doubling the expiry. + Forwarding nodes could then reject the onion with `expiry_too_far`. + +- [libsecp256k1 #1765][] adds an optional `silentpayments` module that + implements the elliptic-curve operations defined by [BIP352][] [silent + payments][topic silent payments]. For + senders, one function combines the sender's input private keys, the + transaction's lowest outpoint, and the recipient's published scan and spend + public keys to derive the output keys that the transaction should pay. For + receivers, full-node scanning detects which of a transaction's outputs + belong to the recipient and returns the tweaks needed to spend them, working + from only the recipient's scan secret key and spend public key so the spend + private key can stay offline. Separate functions manage labels, an optional + [BIP352][] feature that lets recipients derive distinguishable variants of + their address to tell incoming payments apart and flag their own change. + Light client scanning support was deferred to a later PR. + +- [Rust Bitcoin #6317][] updates its [compact block relay][topic compact block + relay] decoding to reject `sendcmpct` messages whose boolean announcement + field is not exactly `0` or `1`, as required by [BIP152][]. Previously, Rust + Bitcoin decoded the field with a non-zero test, accepting any non-zero value + as true (high-bandwidth mode). This PR mirrors the hardening equivalent in + Bitcoin Core (see [Newsletter #412][news412 sendcmpct]). + +- [BTCPay Server #7457][] adds the ability to import [wallet labels][topic + wallet labels] in [BIP329][] JSON Lines format, complementing the existing + export functionality. Previously labels were effectively lost when moving to + another server, and label files produced by BIP329-aware wallets such as + Sparrow or Envoy could not be loaded at all. The importer reads the format's + `tx`, `addr`, and `output` records and maps them to BTCPay's transaction, + address, and UTXO objects, skipping any records it can't apply. + +- [BLIPs #71][] adds a `dnssec_error` response to [BLIP32][], the protocol + that resolves [BIP353][] human-readable payment names by carrying DNSSEC + queries and proofs over Lightning onion messages (see [Newsletter + #306][news306 blip32]). Previously the protocol only defined `dnssec_query` + and `dnssec_proof`, so resolvers that could not respond had no standardized + way to indicate this to the requester, who would continue to wait.
