The advantage is largest on x86_64, where validation is over +five times faster. In practice, this translates to a raw reindexing and new +block validation times that are less than half of what it was before. + +Libsecp256k1 has undergone very extensive testing and validation. + +A side effect of this change is that libconsensus no longer depends on OpenSSL. + 0.12.0 Change log ================= |
