- In an effort to reduce the cost of blockchain verification, blockchain research and development company NEBRA is introducing a new technique called Universal Proof Aggregation. This technique combines several zero-knowledge proofs into a single, compact proof.
- According to NEBRA CEO Shumo Chu, the intricacy of the calculation required to create zero-knowledge technology can be expensive, which may be preventing its widespread use.
In an effort to reduce the cost of blockchain verification, the blockchain research group NEBRA is introducing a method called Universal Proof Aggregation, which combines several discrete zero-knowledge proofs into a single, compact proof.
In an effort to lower the expensive fees associated with proof settlement, the system is going live on Ethereum. The blockchain industry uses zero-knowledge technology, which allows for verification without disclosing information, in components like zkVM, zkRollups, and zk coprocessors.
Shumo Chu, co-founder and CEO of NEBRA, stated in a statement that two significant barriers keeping applications from fully utilizing ZKP technology are low throughput and expensive verification costs.
The complexity of the computing required to implement zero-knowledge technology can make it expensive. On the Ethereum.org blog, there is an estimate that says it takes about 500,000 gas to validate a zk-SNARK proof for zk-rollups on Ethereum. In the end, consumers that pay rollup operator fees to offset computational costs bear the brunt of these charges.
According to a NEBRA representative, the NEBRA aggregator can save expenses by up to 10 times when merging several ZK proofs that aim to settle their batched data onchain rather than verifying things like a ZK rollup separately. Among the earliest users of the universal proof aggregator were Brevis, Altlayer, and Worldcoin.
Nebra UPA can be compared to a blockchain-based carpool for zero-knowledge proofs. They stated that everyone saves more the more people you pick up, just like with Uber Share. Furthermore, unlike other app-specific or VM-specific aggregations that rely on the inherent volume within their respective ecosystems, UPA is open and universal, which enables it to rapidly acquire proofs from a wide range of sources and shorten the time required to achieve economies of scale.
Earlier, NERBA had raised $4.5 million in pre-seed and seed round capital, including participation from Bankless Ventures, Nascent, and a16z’s Crypto Startup Accelerator.
