The brief

Analyst view

• ZKsync Era runs 19+ ZK chains. Airbender prover generates proofs in subseconds on GPUs; Ethereum settles in minutes.
• ZK Stack lets enterprises build their own ZK blockchains with customizable gas tokens, sequencing models, and data availability.

Technical approach

As reported

ZK Proofs

Cryptographic finality without validators

ZKsync uses zero-knowledge proofs to verify transaction batches. Ethereum cryptographically confirms proof validity; no trusted validator set needed.

Airbender Prover

RISC-V proof system

Airbender generates block proofs in subseconds on GPUs, enabling Ethereum finality within minutes.

ZK Stack

Framework for custom ZK chains

ZK Stack is an open-source toolkit for enterprises to build dedicated ZK blockchains with their own gas tokens, sequencing, and data availability layers.
