Since #29058, several types of manually configured connections will attempt v2 connections when `-v2transport` is enabled, except for the `addnode` RPC, as that one has an explicit argument to enable...
This implements a safegcd-based modular inverse for MuHash3072. It is a fairly straightforward translation of [the libsecp256k1 implementation](https://github.com/bitcoin-core/secp256k1/pull/831), with the following changes: * Generic for 32-bit and 64-bit * Specialized...
### Current logic Since #3370, our logic for deciding which chain is active has been: 1. Among chains for which all transactions have been received, and are not known to...
While investigating an issue with a non-propagating transaction with @TheBlueMatt, it occurred to us that it can be a problem for a node to get its transactions relayed when it's...
Built on top of #1118, this adds API calls to the ecdh module to support x-only ECDH. When pubkey decompression is included in the ECDH benchmark, it's roughly 10% faster...
Algorithm by Peter Dettman, with original comments: > Changes to _divsteps_59 (_30) that give maybe 4% speed improvement to const-time modinv on 64 bit. I see a larger gain on...
This merges the `BuildDiagramFromChunks` and `CompareFeeRateDiagram` introduced in #29242 into a single `CompareChunks` function, which operates on sorted chunk data rather than diagrams, instead computing the diagram on the fly....
Feerate comparisons in the recently (#29242) introduced `FeeFrac` type rely on multiplications between 32-bit and 64-bit integers. On 64-bit systems, hardware can do this natively. On GCC and Clang we...
The linear mapping tables for squaring/squarerooting/solving x^2+x+a/converting between field representations are currently all encoded very compactly in the C++ code, and get expanded at compile time (through `constexpr`) into full...
