APRO and Brevis join forces to strengthen the next generation of demonstrable oracles

APRO, the most popular oracle network on $BNB Chain has unveiled an intensive technical collaboration with Brevis, a leader in zero-knowledge (ZK) coprocessing, with the aim of redefining the nature of how oracles acquire, verify and deliver information to smart contracts. The partnership is a strategic use of cryptographically provable data as a shift away from consensus-based oracle models.

The partnership is not merely an integration, but represents a convergence of two layers of the Web3’s fundamental infrastructure. APRO’s multi-chain oracle network with Brevis’ ZK proof stack and its ZK Data Coprocessor, ZKTLS technology and Pico zkVM are integrated. The teams are jointly constructing what they say is a new generation of oracles of which they are demonstrable and not socially proven.

Going beyond social consensus

Conventional oracle systems are based on validator sets that retrieve and report data with consensus in deciding which value should be considered correct. While this design has powered much of modern DeFi, this structure has tradeoffs in terms of latency, higher costs, and fair majority assumptions.

APRO and Brevis attempt to solve these problems by replacing the assumptions of trust with the guarantees of cryptography. The data is accompanied by zero-knowledge proofs in the new model, which guarantees how the data was obtained and calculated.

Verifiable historical data in the chain

The historical data about the chain is one of the areas of focus. Brevis’ ZK Data Coprocessor allows one to create off-chain historical blockchain data calculations and be verifiable as summary ZK proofs.

APRO’s oracle network then transfers the output and evidence to the blockchain where smart contracts can 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 demonstrable past activity rather than subjective reporting.

Off-chain authentication of public data

The alliance also improves the process by which public data imported outside the chain is transferred to the chain. Sports, financial, or election results are examples of data that traditionally rely on the belief that oracle nodes have access to correct information in external forms. Brevis’ proposed ZkTLS technology presents cryptographic trust as proof that data is accessible via an authoritative TLS connection over the appropriate domain.

Brevis goes further to demonstrate via Pico zkVM that the data has indeed been read correctly to convey the values ​​in question. APRO incorporates this proof pipeline into its oracle delivery, allowing smart contracts to use off-chain data on cryptographic authenticity certificates instead of using node honesty.

Unlock verifiable private data feeds

In addition to publicly available data, the partnership opens access to confirmable private and proprietary data feeds. Not everything of value can be made public, including algorithmic trading indexes or business statistics. With Brevis zkVM, data providers can prove that an output has been properly derived using recorded private data or algorithms, without making the underlying information public.

APRO acts as both the delivery layer of this evidence and allows decentralized programs and prediction markets to confidentially pay for proprietary information. This creates completely new markets where trust depends on cryptography instead of reputations.

Privacy for market participants

In addition to data verification, the partnership also aims for user-level privacy. Open blockchains reveal traders’ patterns, causing threats to front-running and copy strategies. APRO and Brevis are also developing privacy-preserving programs, where traders demonstrate they are trading according to market rules using ZK proofs that do not reveal addresses, positions or strategies.

The infrastructure will enable institutional-level engagement in on-chain markets, especially in the ever-expanding prediction market ecosystem $BNB Chain.
