Hisoka is a team of cryptographers building privacy infrastructure for Ethereum.
Privacy is not a feature we add later. It is the foundation. Every protocol we ship is built so that no single point — no node, no provider, no relay — can leak who you are or what you want.
Hisoka is a compliant dark pool protocol where every layer of interaction is private. Not just your trades. Your queries, your API requests, your network traffic. All of it. We protect writes with zero-knowledge proofs, reads with private information retrieval, and the network with mixnet routing.
Every protocol we ship is open source. We collect no data and store no logs nor metadata. The systems are designed so that even if every node operator were adversarial, the cryptographic guarantees hold. Privacy is structural, not policy-dependent.
Every transaction, query, and network interaction is private from the first packet. Users do not opt in to privacy. They would have to opt out, and there is no mechanism to do so.
The network is permissionless. Security derives from cryptography and protocol design, not from trusting operators, relayers, or the team. Don't trust, just verify.
Threshold encryption keeps every transaction private by default. Surgical decryption requires a 15-entity quorum and public evidence. Privacy for all. Accountability when legally required.
We take no political positions and serve no special interests. The tools we build are neutral infrastructure. They work the same way for every user on every transaction. We do not build backdoors, we do not maintain key escrow, and we do not design systems that require trusting us.
Our research is public. Our code is auditable. Our protocols are formally specified. We believe that privacy infrastructure only works if it can be independently verified, and that verification is only meaningful if the system is simple enough to reason about.
We ship working systems, not whitepapers. Every protocol we publish has a production implementation, a test suite, and published benchmark data. The Nox mix network is testnet-live with 33,000 lines of Rust and 602 tests. We hold ourselves to the standard we think the field should adopt.
