TechFlow news, on August 15, according to The Block, blockchain research firm NEBRA announced the launch of "Universal Proof Aggregation" technology, which allows multiple zero-knowledge proofs to be combined into a single compact proof, thereby reducing blockchain validation costs. The system has gone live on the Ethereum mainnet, aiming to reduce high proof settlement fees.
Zero-knowledge technologies have high implementation costs due to computational complexity, limiting their widespread adoption. According to estimates from the Ethereum.org blog, verifying a zk-SNARK proof on Ethereum costs about 500,000 gas, with these fees ultimately paid by users to subsidize computation costs. NEBRA's aggregator reduces costs to one-tenth of the original by batching and settling multiple ZK proofs on-chain. NEBRA CEO Shumo Chu stated that low throughput and high verification costs are the primary obstacles preventing applications from fully leveraging ZKP technology.
Previous report, NEBRA raised a $4.5 million seed round led by Nascent and Bankless Ventures, with participation from a16z's Crypto Startup Accelerator.
