Brevis is partnering with @APRO_Oracle to develop trust-free oracle infrastructure on @BNBCHAIN. The goal: oracles that prove their data mathematically rather than through validator consensus. 🧵

Traditional oracles work through attestation. Validators observe data, sign it, and majority opinion becomes on-chain truth. This introduces latency, cost, and trust assumptions. Validators can collude. Disputes need arbitration. And the "always-on" model creates overhead when you only need data at specific moments.

ZK proofs offer an alternative. For on-chain data: Brevis's ZK Data Coprocessor computes over historical blockchain state and proves the calculation is correct.

For off-chain public data: Brevis zkTLS proves content was retrieved through a genuine TLS session from the authentic source. Pico zkVM then parses it. Single-step verification, no multi-party vote needed.

For private data: Providers commit algorithm hashes on-chain, then publish results with ZK proofs. Users verify outputs follow the stated methodology without seeing underlying data. Across all three categories, Brevis provides the verification layer that enables APRO to deliver trust-free oracle services. 🔐

The collaboration also explores privacy for prediction market traders. Trade intentions, arbitrage paths, timing, positions, address correlations - all visible on public blockchains. ZK proofs let traders verify their transactions are valid without exposing these details.
