What is ZKsync (ZK)?

Deep Dive

1. Purpose & Value Proposition

ZKsync addresses Ethereum’s scalability bottlenecks by processing transactions off-chain and bundling proofs on Ethereum. Its ZK-Rollups compress data, reducing fees by ~90% compared to Ethereum mainnet. The protocol emphasizes “native interoperability,” allowing chains in its Elastic Network to share liquidity and execute atomic transactions.

2. Technology & Architecture

Built on zkEVM (Zero-Knowledge Ethereum Virtual Machine), ZKsync maintains compatibility with Ethereum smart contracts. Its Airbender zkVM (released June 2025) processes Ethereum block proofs in 35 seconds using RISC-V architecture, enabling decentralized at-home validation. The Gateway interoperability layer facilitates communication between ZKsync Chains, with transaction fees paid in $ZK.

3. Ecosystem Fundamentals

• Prividium: A compliance-ready platform for institutions, co-developed with Deutsche Bank, offering private transactions anchored to Ethereum.
• ZK Success: A community program fostering decentralized support and education (GitHub).
• Real-world traction: Cited in a White House report as critical infrastructure for digital identity and payments.

Conclusion

ZKsync combines Ethereum’s security with scalable ZK tech, positioning itself as a hub for interoperable chains and institutional blockchain adoption. As its Elastic Network expands, can it balance decentralization with enterprise-grade privacy demands?
