2 6 3 Considerations before using bridge aggregators The use of bridge aggregators that allow for multi-step or multi-hop bridging increases the likelihood of a transaction failure These aggregators incorporate various protocols, including different bridges and DEXs, each with their own security features and risks
- zkLink: An Aggregated Rollup Infrastructure Based on Zero-Knowledge . . .
5 1 Commit: The sequencer submits the zk-proof and transaction batch to the verifier contract on the primary chain 2 Prove: The zkLink contract on the primary chain verifies the validity of the zk-proof 3 Synchronization: The transaction sync hashes of secondary chains are forwarded to the primary chain via secure message channels The primary chain verifies if sync hashes are
- Cross-Blockchain Communication Using Oracles With an Off-Chain . . .
The aggregator verifies the votes and changes the balances of committee members based on their participation during the execution of the aggregation mechanism The aggregator only submits a zk-SNARK, the query result, and the updated Merkle tree with the account information to the zkOracle contract Hence, the aggregation mechanism requires
- zkBridge: A Breakthrough Technology for Security and Privacy in . . .
zkBridge — a new approach to data security and privacy in blockchain systems, based on the use of zero-knowledge proofs (zk-SNARKs) The zkBridge technology enables the creation of secure and anonymous connections between different blockchain networks, making it a key element in the development of decentralized applications (dApps) and ensuring data privacy in distributed networks
- What Zero Knowledge Rollups (Zk-Rollups) Are, Versus . . . - CoinGecko
Zk-rollups verify transactions with less data handled on-chain, with the goal being cheaper gas fees and faster transaction time since the proofs are immediately verifiable In contrast, optimistic rollups assume transactions are valid by default, which in theory requires posting more transaction data on-chain, potentially leading to higher gas
- zkBridge
Integration of zero-knowledge proof technology will enhance security, performance, and cost-efficiency for cross-chain interoperability on all chains supported by LayerZero
- Overview of Polygon zkEVM: How the Layer 2 solution for . . . - Medium
With the obtained zk-proofs, the aggregator goes to the L1 PolygonZkEVM sol contract and consolidates the batch state At this stage, the transactions are considered complete and included in the
- Blockchain-Enabled Zero Trust Architecture for Privacy-Preserving . . .
By decentralizing identity management and enabling multi-factor authentication, QBC-ZKPAF provides robust security and privacy solutions for IoT networks The experimental results demonstrate the model’s effectiveness with 98% privacy preservation, 700 TPS throughput, 0 7 J energy consumption, 0 98 quantum resilience, and 96% access control
