Notable changes

===============

|
Signature validation using libsecp256k1
|
||
|
|
---------------------------------------
|
||
|
|
|
||
|
|
ECDSA signatures inside Zcash transactions now use validation using
|
||
|
|
[https://github.com/bitcoin/secp256k1](libsecp256k1) instead of OpenSSL.
|
||
|
|
|
||
|
|
Depending on the platform, this means a significant speedup for raw signature
|
||
|
|
validation speed. 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 upstream.
|
||
|
|
|
||
|
|
A side effect of this change is that libconsensus no longer depends on OpenSSL.
