Zero-knowledge proof platform NEBRA has launched its Universal Proof Aggregation solution, bringing the benefits of ZKP verification to the crypto industry.
Launched on Ethereum (ETH), NEBRA UPA is a protocol that combines zero-knowledge proofs into a single proof to provide cost-effective on-chain verification. The UPA protocol is designed to enhance scalability and privacy across blockchains by aggregating proofs, Nebra The team said in a joint press release with crypto.news.
“Low throughput and high data validation costs are two major barriers that prevent applications from taking full advantage of ZKP. But with NEBRA UPA, ZKP is no longer just a dream for the future – it is a solution that is available and being used now.”

Solution for zkEVM and RaaS protocols
Protocols and projects that benefit from the UPA solution include zero-knowledge virtual machines, coprocessors, aggregation-as-a-service solutions, and consumer applications.
An example of the latter is the WorldCoin (WLD) project, which uses ZKP to verify that a user is a unique human. The project’s World App uses this technology to prove identity without revealing any information. Other notable projects in the ZKP ecosystem include Polygon zkVM, ZK Sync, and Starknet.
Cost issue
ZKP costs may be steep, but UPA is looking to reduce this cost from $20 to $2 for Ethereum and from $2 to $0.2 for layer 2 solutions. A significant reduction in the cost of ZK proof for everyday crypto use cases, such as buying coffee, would empower developers and add to adoption across decentralized applications.
“Who wants to pay $20 for a coffee using ZK technology? But when the cost drops to a few cents, endless possibilities open up for developing decentralized applications,”
-Co-founder of Nebra Yi Tong.
NEBRA has raised a total of $4.5 million in funding from crypto venture capital firms including Andreessen Horowitz, Bankless Ventures, and Nascent. The platform plans to deploy UPA v2 on top L2s to allow more decentralized applications to benefit from the lower cost benefits of using ZKP on-chain.
