Privacy, Cryptography,
and Blockchain Applications.
Personal Portfolio
Hi! I'm Yoi, a software developer, cryptography engineer, and a privacy enthusiast. I'm also a big fan of open-source software and I love to contribute to the community. I also love to participate in hackathon! Feel free to check out my works and don't hesitate to reach out to me if you have any questions or just want to say hi!
PROJECTS
A collection of projects I've previously and currently worked on.
Fullstack (Frontend, Backend), Some of the data pipeline
Governance dashboard for Optimism focusing on participation, voter behavior, power structure, proposal outcomes. Providing insights and democratizing information for informed decision-making in governance process.
Curia Lab
OptimismHACKATHONS
A collection of hackathons I've participated in.
Night Market
Multi-Asset Shielded Pools with external interaction and compliance features. Trade, LP, stake, and more privately while comply with regulators
ECDSA Signing In Tfhe-rs
Experiment and technical report on implementing fully homomorphic encrypted elliptic curve digital signature algorithm (ECDSA) using tfhe-rs
ZTF
Decentralized cross-chain bounty and crisis management protocol. A.k.a. On-chain ctf with claimable bounty using zero-knowledge proof.
Turing Zero zkVM
Turing Zero zkVM is a zk circuit simulating a simple Turing machine, and the circuit can prove that given a public input tape and output tape, there is a program witness that sucessfully simulate with such tape.
Type-5 zkEVM
Type-5 zkEVM is a 30-ish opcodes/instructions simplified EVM that captures important concepts like state transition proof, opcodes, etc. Users can easily add/modify opcodes or VM behaviour due to our small, easily-read codebase.
Frames Hub
FrameHub is frames aggregator with additional analytic on Farcaster aim to capture the trends, engagement to enhance project decisions. We offer a FrameHub website to monitor and analyze trends of Frames on Farcaster, and a FrameHub account on Farcaster to send daily updates on for Farcaster users to keep updates on the trends.
EVM Trace
EVMtrace aims to shed light on adopting cryptography on chains. Collecting data with techniques like tracing, tracking precompiles, pattern recognition, and manual works. EVMtrace provides a user-friendly dashboard and etherscan-like tools.
BlockElf
BlockElf enables users to query on-chain data using natural language. Our product abstracts the complexities of on-chain queries, making this vital data accessible to everyone, regardless of their technical expertise.
Noiri
Noiri is a privacy-preserving money market protocol on Ethereum L1 powered by Noir. Users can lend, borrow, repay and withdraw with interest, while keeping their positions private. Liquidations are triggered publicly but the liquidated positions remain private.
Shroud
Shroud is the first fully functional privacy-preserving DApp on the Sui blockchain, enabling confidential and compliant trading by integrating zero-knowledge proofs with public DEX infrastructure.
