APRO and Brevis partner to power the next generation of provable oracles

APRO is the world’s most popular oracle network. $BNB Chain announced an intensive technology partnership with Brevis, a leader in the zero-knowledge (ZK) co-processing space, aimed at redefining the nature of how oracles source, verify, and deliver information to smart contracts. This partnership is a strategic use of cryptographically provable data as a transition from the consensus-based oracle model.

This partnership is more than just an integration; it represents the integration of two layers of Web3’s underlying infrastructure. It integrates APRO’s multi-chain oracle network with Brevis’ ZK proof stack and its ZK data coprocessor, ZKTLS technology, and Pico zkVM. Together, the team is building a new generation of oracles that are provable rather than socially proven.

Moving beyond social consensus

Traditional oracle systems are based on validator sets where data is captured and reported based on consensus in determining which values ​​are considered correct. While this design has driven much of modern DeFi, this structure has tradeoffs in terms of latency, increased costs, and honest majority assumptions.

APRO and Brevis seek to solve these problems by replacing trust assumptions with cryptographic guarantees. The new model attaches zero-knowledge proofs to the data, guaranteeing how the data is acquired and computed.

Verifiable on-chain historical data

On-chain historical data is one of our areas of focus. Brevis’ ZK data coprocessor allows you to compute off-chain historical blockchain data and verify it as a concise ZK proof.

APRO’s oracle network at the time transferred outputs and evidence to the blockchain, where smart contracts could verify past claims without trust. This feature is useful in enabling new types of applications such as prediction markets and financial primitives that rely on provable past activity rather than subjective reports.

Authentication of off-chain public data

The partnership will also improve the process by which public data imported from off-chain is brought on-chain. Sports, finance, and election results are examples of data that traditionally rely on the belief that oracle nodes are accessing the correct information in an external format. The ZkTLS technology proposed by Brevis indicates the authenticity of the encryption as establishing the fact that the data was accessed by an authoritative TLS connection through the proper domain.

Through Pico zkVM, Brevis demonstrates that the data was actually read in the correct way to convey the value in question. APRO incorporates this attestation pipeline into oracle distribution, allowing smart contracts to use off-chain data with cryptographic certificates of authenticity instead of using node honesty.

Unlock verifiable private data feeds

In addition to publicly available data, this partnership opens access to verifiable private and proprietary data feeds. Not everything of value, such as algorithmic trading indexes or company metrics, can be made public. Brevis zkVM allows data providers to create evidence that outputs were properly derived using committed private data or algorithms without disclosing the underlying information.

APRO serves as a distribution layer for this evidence, allowing decentralized programs and prediction markets to pay for proprietary information while remaining confidential. This establishes an entirely new market where trust is anchored by cryptography rather than reputation.

Market participant privacy

In addition to validating data, the partnership also aims to ensure user-level privacy. Open blockchains reveal traders’ patterns, which poses a threat to front-running and copying strategies. APRO and Brevis are also developing privacy protection schemes. In this scheme, traders use ZK proofs that do not reveal their address, positions, or strategies to prove that they are acting according to market rules.

This infrastructure enables institutional-level involvement in on-chain markets, especially the ever-expanding prediction market ecosystem. $BNB chain.
