NEBRA launches zero-knowledge proof aggregator and goes live on the Ethereum mainnet, reducing Ethereum verification costs.

On August 15, according to The Block, the blockchain research institution NEBRA announced the launch of the "Universal Proof Aggregation" technology, which allows multiple zero-knowledge proofs to be merged into a single compact proof, reducing the cost of blockchain verification. The system has been deployed on the Ethereum mainnet to reduce the high settlement costs of proofs. Zero-knowledge technology incurs high implementation costs due to computational complexity, limiting its widespread application. According to Ethereum.org blog estimates, verifying a zk-SNARK proof on Ethereum costs about 500 thousand Gas, which is ultimately paid by users to subsidize computational costs. NEBRA's aggregator settles batch data of multiple $ZK proofs on-chain, reducing costs to one-tenth of the original. NEBRA CEO Shumo Chu stated that low throughput and high verification costs are the main obstacles hindering the full utilization of ZKP technology. In previous news, NEBRA secured a $4.50 million seed round funding led by Nascent and Bankless Ventures, with a16z's Crypto Startup Accelerator also participating.
