Bitcoin Core 0.12 checks signatures with libsecp256k1
Bitcoin Core 0.12.0 began checking transaction signatures with libsecp256k1 instead of OpenSSL, through a change by Pieter Wuille. The release notes said signature checks became over five times faster on x86_64 processors, and new blocks took less than half as long to validate.
