Redefining
Interoperability
THE LIGHT CLIENT LAYER FOR THE NEXT GENERATION OF TRUSTLESS INTEROPERABILITY.
Light clients for every chain. Universal verification, on demand.
Light Clients Before
Bankai
Complex infrastructure and high costs are limiting adoption of current ZK light clients: Custom deployments are needed for every chain while proofs need to be constantly verified onchain.
Bankai Stateless
Light Clients
Bankai Stateless Light Clients sync offchain, cut ongoing transaction costs, and verify Groth16 proofs on demand, enabling inexpensive, lean interoperability across chains with no custom deployments.
Bankai: The Light
Client Layer
We're starting with Ethereum: building a stateless light client for both the execution and beacon chain.
But our vision is much bigger: One proof layer, spanning many chains. Trustless interoperability that's simple, universal, and built to scale.
- Universally deployable
- Lightweight
- Cost-efficient
Deterministic
by Design
We don't create consensus, we compress it. Each Bankai proof is a deterministic result of a chain's finalised history. This creates a single, canonical proof of truth that can be verified anywhere, instantly—no extra checks required.
Technical Roadmap
A staged rollout to ship the first stateless Ethereum light client, then scale Bankai across chains with developer-grade tooling.
Ethereum Mainnet
Bankai v1 mainnet live, giving stateless access to execution and beacon chain.
Ethereum L2 Light Clients
Adding L2 light clients to Bankai, extending usability.
Tendermint L1 Light Clients
Integrate Tendermint-based chains into Bankai.
Solana Light Client
Integration of a Solana light client based on Alpenglow consensus.
