Release v3.1.0

Release notes v3.1.0 🎉

This is a minor release

• Added Schnorr256 library that verifies Schnorr signatures over any 256-bit curve.
• Added EC256 library that implements optimized elliptic curve operations via Jacobians over any 256-bit curve.
• Refactored ECDSA256, ECDSA384, and ECDSA512 libraries to automatically calculate the lowSMax variable.

Release v3.0.2

Release notes v3.0.2 🎉

This is a patch release

• Added storage buckets to the all access contracts.

Release v3.0.1

Release notes v3.0.1 🎉

This is a patch release

• Removed AInitializableStorage contract as it conflicted with OZ Initializable. The existing Diamond logic can be rewritten with the reinitializable modifier if diamond cuts are used.

Release v2.7.16

Release notes v2.7.16 🎉

This is a minor release

• Added U512 library for hyper-optimized on-chain BigInt arithmetic.
• Added ECDSA512 signature verification library which consumes 13.6 mln gas.

Release v2.7.15

Release notes v2.7.15 🎉

This is a patch release

ECDSA384

• Handled a double scalar multiplication edge case (fixes #125 and #126).
• Implemented 6-bit Strauss-Shamir precompute table which saved 75k gas.

Release v2.7.14

Release notes v2.7.14 🎉

This is a minor feature release

• Added novel Cartesian Merkle Tree (CMT / Treaple) data structure reference implementation.
  • CMT can be used as a substitute for a Sparse Merkle Tree (SMT) when a hash function cost is low.
  • CMT consumes 2 times less storage than SMT.
  • With keccak256 CMT is 18% less expensive than SMT.
• Optimized ECDSA384 library signature verification to ~8.1 mln gas (previously ~9 mln).
