This comprehensive library powers Zeus' smart contracts, backend infrastructure, and developer tooling. I engineered a high-performance Secp256k1 library that facilitates on-chain signing, verification, point addition, key tweaking, and ECDSA signature verification. Notably, I created the world’s first Solana implementation of Secp256k1 Schnorr signatures, reducing verification CU costs from 5,000,000 to an unprecedented 34,000 CUs.I also developed an on-chain Bitcoin light client for Solana, enabling comprehensive verification of the Bitcoin blockchain on-chain, effectively transforming Solana into a Bitcoin node. Additionally, I implemented indexing and tooling solutions to support Bitcoin metaprotocols on the Solana network, enhancing its functionality and interoperability. Show less
