What is Brevis?
Brevis is a zero-knowledge coprocessor for blockchains. It lets smart contracts run heavy computations and read historical on-chain data off-chain, then verify the result with a succinct ZK proof, so the chain trusts the answer without redoing the work. Its ProverNet is a marketplace where independent provers compete to generate those proofs. BREV is the network's token. It is used to pay for proof generation, to stake as a prover, and for governance, with future use as gas. The token launched in early 2026 with a fixed supply of one billion, and ProverNet started on Base with plans to move to a dedicated rollup. Brevis is infrastructure aimed at developers rather than a consumer product, and as a recently launched token its long-term role depends on adoption of verifiable off-chain compute. You can track the Brevis price and hold BREV in a self-custody wallet.
