Let’s enter @brevis_zk V2 together:
A ZK coprocessor that lets devs trustlessly read, compute, and prove insights from the entire history of supported blockchains.
Think of it as “Google BigQuery” for crypto, except it’s verified with zero-knowledge proofs instead of vibes.
So how does it actually work?
➤ Data Access – Devs specify what historical data they want (block headers, transactions, events, etc).
➤ Computation – Brevis runs your logic via an SDK that abstracts all the painful ZK stuff.
➤ Proof + Verify – Brevis generates a ZK proof off-chain, and smart contracts verify it on-chain, trustlessly.
Example:
A DEX could use Brevis to prove someone traded $3M volume across 350 swaps. All verified directly on-chain, no Dune dashboards or SQL hacks needed.
No ZK background? No problem.
Brevis’s SDK is built on gnark (by Linea/Consensys), but wrapped in dev-friendly abstractions.
So what’s next?
➣ 10x performance boost cooking in dev
➣ More supported data types
➣ Cross-chain expansion
➣ coChain on EigenLayer to slash ZK costs even more
In short, Brevis just turned “on-chain data” from something you look at into something you can actually compute on and that’s not a small upgrade.

Brevis gave ZK Coprocessors a brain transplant
Forget the “pure-ZK” struggle where everything’s slow, costly, and allergic to scale.
@brevis_zk dropped Brevis coChain, a “propose-challenge” model that merges Proof-of-Stake + Zero Knowledge = cheaper, faster, and actually usable data coprocessing.
Here’s the decode for non-nerds ⇓
Old model (Pure-ZK):
Every result = ZK proof. Secure? Yes. Scalable? Not really.
Expensive to compute, high latency, and can’t even prove simple stuff like who didn’t trade.
New model (coChain):
Validators “propose” results via PoS consensus, no proof needed, no upfront.
If someone spots a lie, they can throw down a ZK challenge, and bad validators get slashed.
If no one challenges? The result stands.
Think of Brevis like this:
Pure-ZK = absolute truth, but slow and pricey.
CoChain = optimistic truth, but with real-time fraud protection and PoS enforcement.
