Brevis ZK Solution by Celer

Celer Network has built Brevis, a “Zero-Knowledge (ZK) omnichain data attestation platform” that enables smart contracts to access and compute data from any blockchain.

“Brevis has a wide range of use cases like data-driven DeFi, zkBridges, on-chain user acquisition, zkDIDs, social account abstraction, and much more,” according to an announcement from Celer.

According to Celer, any off-chain products such as Dune Analytics and Graph provide off-chain data indexing or analytics; however, Decentralized Applications (dApps) generally have had no way to access blockchain data unless it is “via explicitly defined interfaces of other smart contracts,” on the same blockchain and in the most current state of the blockchain.

Oracles can offer solutions to this quandary but then require additional reliance on the oracles’ security. And while other on-chain solutions “are in theory possible,” they have not been feasible due to high computation costs, according to Celer.

Enter the emerging ZK technology, which dramatically reduces blockchain transaction costs and time.

“It is important to note that the key difference between Brevis and off-chain data indexing solutions such as Dune Analytics and Graph is that Brevis can generate zk-attested query results that can be directly utilized by the business logic of on-chain smart contracts in a trust-free way,” according to Celer. “Compared to off-chain solutions whose data results can only be used in the web2-based data analytic context.”

As an initial proof of concept for Brevis, Celer built ZK light client circuits for Ethereum, Cosmos and BNB Chain that enable any Ethereum Virtual Machine (EVM) or non-EVM chain to access the states of those three chains in a trust-free way, according to the announcement.

“Using these ZK light client circuits, we implemented a user-facing asset zkBridge between Ethereum Goeril and BNB Chain Testnet for users to try out,” Celer said.

Celer has gone deep into ZK technology, aspiring to build a “Pantheon of Zero Knowledge Proof” comprising “a universally recognized evaluation testbed that covers low-level circuit development frameworks, high-level zkVMs and compilers, and even hardware acceleration providers.”
