zkLink Nova: A general-purpose Aggregated Layer 3 zkEVM network that allows seamless Ethereum-compatible DApp deployment. Fortify Your Investments with Unmatched Security With zkLink Nexus and advanced ZK Stack from Matter Labs, enjoy peace of mind as all transactions inherit Ethereum's robust security after meticulous ZKP verifications & multi-chain states synchronization.

Therefore, we propose an oracle with an off-chain aggregation mechanism based on Zero-Knowledge Succinct Non-interactive Arguments of Knowledge (zk-SNARKs) to facilitate cross-blockchain communication. The oracle queries data from another blockchain and applies a rollup-like mechanism to move state and computation off-chain.

The ZK verification layer can be useful anytime ZK is used with Ethereum, but some clear use cases are described in this section. ZK-rollups and Ethereum scaling Rollups produce ZK proofs of state transitions and need to verify (settle) those results on Ethereum.

However, when constructing a multipurpose solution that involves verifying various SNARKs, non-algebraic hashes, or aggregating signatures of different types - where non-native arithmetic is inevitable - I would certainly leverage a recursive STARK for proof aggregation.

Therefore, we propose an oracle with an off-chain aggregation mechanism based on ZeroKnowledge Succinct Non-interactive Arguments of Knowledge (zk-SNARKs) to facilitate cross-blockchain communication. The oracle queries data from another blockchain and applies a rollup-like mechanism to move state and computation off-chain.

The market will provide competitively priced, highly available, and decentralised proving to ZK applications. Proof Aggregator: Today, the minimum cost for verifying a proof on-chain is ~200k gas.

Built with ZK Stack, developers enjoy an EVM-compatible open platform for deploying Solidity smart contracts. As a Layer 3, zkLink Nova’s key value proposition and differentiator is its asset aggregation feature that provides users with a simplified platform for multi-layer yield and developers with an EVM-compatible network for easy ...

Instead, we would be concatenating multiple ZK proofs, and verifying them one by one in the aggregator contract. But if the proof system supports aggregation, then multiple ZK proofs could actually be compressed into one. But we need proof aggregation to happen in Solidity, unless it is popular enough all bundlers are willing to do it off-chain.

From securing sensitive data to verifying proof of humanhood or photo authenticity; proofs are becoming essential components in our highly digitized world. zkVerify has effectively commoditized access to these proof systems that would otherwise be unusable on major chains like Ethereum.
