The studio I build with
Jino Labs is an engineering studio for deep infrastructure work, on chain systems, MEV, DeFi and high-throughput backends. Most of its current output is Zcash infrastructure, built in the open, alongside tooling for working with AI agents.
Everything listed here is studio work built together. Earshot is the piece I built on my own.
Watch and steer Claude Code agent sessions across machines from one page. End-to-end encrypted so the relay never sees code or prompts, with guest links that can watch but never issue commands. Published on npm with zero runtime dependencies.
Snapshot sync for Zebra. It bootstraps a fresh Zcash node from a hash-verified state snapshot in seconds instead of replaying the chain from genesis, and Zebra then validates every later block as normal. A testnet-validated prototype.
A self-sovereign faucet running its own node, wallet and miner, paying shielded drips and gating claims with browser proof of work instead of a third-party captcha.
Ten hands-on challenges that take a developer from their first shielded transaction to a first merged pull request, on a real in-browser testnet wallet.
Got a problem like this one? I would love to hear about it.
