We still have #19263 open but this should not stop us from updating here. |

Ran the subtree linter locally, manually checking hashes: Also as an exercise, ran the same update exercise, code matches: ACK 894fb33 |

Looks like this bump unconditionally forces Valgrind calls on systems with Valgrind headers. Opened bitcoin-core/secp256k1#813 to address. |

@luke-jr Nothing about this PR changes behaviour with respect to valgrind (see my comments on the linked issue). [The line change at https://github.com//pull/19944/files#diff-54d0bb117d455c49976ee2aa20b140eaL102 is just changing it so that the standalone constant time test binary doesn't link openssl if openssl is being used by the test for comparison testing.] |

ACK 894fb33. Any Valgrind concerns will be addressed upstream, see discussion in bitcoin-core/secp256k1#813, and if necessary, can be pulled into our tree prior to the 0.21.0 branch off.

As it adds BIP340 support (see bitcoin-core/secp256k1#558), this is a prerequisite for bitcoin#17977. In particular, it contains: * A few generic library improvements * Support for x-only public keys as used by BIP340. * Support for "key pair" objects, making signing more efficient by using a precomputed public key. * Signing support for BIP340 Schnorr (single-party) signatures. * Verification support for BIP340 Schnorr signatures. * Support for verifying tweaked x-only keys, as used by BIP341's Taproot construction. Things that are not included: * MuSig, nor any kind of multisignatures, threshold signatures, ... on top. * Batch verification. * Support for variable-length messages in BIP340 (which are still being discussed, but won't affect BIP341, or Bitcoin Core). * A few more generic improvements that are still in the pipeline, including faster modular inversions.

This migrates us to the same dependency version that upstream Bitcoin Core migrated to in bitcoin/bitcoin#19944.

Update secp256k1 This migrates us to the same dependency version that upstream Bitcoin Core migrated to in bitcoin/bitcoin#19944. Also enables the endomorphism optimization now that the patents have expired.
