It is not a trust request. It is a verification package. All CI badges track the dev branch — the active development branch where all work happens. Releases are tagged on main only when explicitly authorized by the repository owner. --- What this repository contains - Core engine — CPU/GPU/embedded secp256k1 implementation ( src/cpu , src/cuda , src/opencl , src/metal ). - Compatibility shims — opt-in API-compatible paths for existing projects ( compat/libsecp256k1 shim , compat/libsecp256k1 bchn shim ; not API-identical — see FAQ §drop-in for migration notes). - Bindings/FFI — language integration surfaces ( bindings/ ): C, Python, Node.js, Go, Swift, Rust, Java, Dart, C#, WASM, Android. - CAAS — continuous audit and evidence system ( audit/ , ci/ ); not runtime code. - Reviewer docs — scoped evidence, known limitations, replay commands ( docs/ ). Bitcoin Core PR candidate — scope: the proposed Bitcoin Core integration is the CPU ECDSA / Schnorr (BIP-340) verify + sign backend only — a compile-time secondary backend selected behind the existing libsecp256k1, not a replacement . Explicitly out of scope for that PR (and reviewed/used separately): the GPU backends (CUDA / Metal / OpenCL), WASM, embedded (ESP32/STM32) targets, the non-C++ bindings, and the protocol extensions (FROST, MuSig2, adaptor si","default_branch":null,"files":null,"tree":[],"storefront":"/r/shrec","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/shrec/UltrafastSecp256k1/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
