TL;DR: Why @ZKsync Calls Itself the Bank Stack of @Ethereum The institutional blockchain dilemma: • Public chains (ex: Ethereum, Bitcoin, Solana) → global liquidity but no privacy • Private chains (ex: Hyperledger Fabric, R3 Corda, traditional permissioned setups like Quorum variants) → privacy but cut off from global liquidity • Alternative L1s (ex: Solana, Avalanche, Sui) → lose Ethereum’s security and credibility ZKsync removes this trade-off. It allows institutions to run transactions privately, while still accessing shared liquidity across the network and settling securely on Ethereum. - Core Architecture ↓ • Prividium → Permissioned Validium chains designed for institutional environments. • Elastic Network → Native interoperability across ZK chains (currently 19+) with ~1s confirmations. • Ethereum L1 → Final settlement secured by zero-knowledge validity proofs. - How it works ↓ • Private execution: sensitive transaction data stays inside institutional infrastructure. • Proof-based settlement: only cryptographic validity proofs are posted to Ethereum. • Shared liquidity: private ZK chains can access public liquidity across the Elastic Network. • No bridge risk: interoperability happens without asset-locking bridges. - Enterprise-grade infrastructure ↓ • Selective disclosure for auditors & regulators • SSO integrations (Okta / Azure AD) • Approval workflows & role-based governance • Programmable compliance logic • ERP and treasury system integrations - Institutional adoption is already happening ↓ • Deutsche Bank collaboration through Memento • ADI Chain supporting UAE-licensed stablecoin infrastructure • EDENA Capital onboarding $20B+ sovereign-grade assets • Integrations with Fireblocks, pilots with UBS • $2B+ tokenized RWAs already live on ZKsync - Bottom line ↓ ZKsync is not trying to replace Ethereum. It’s extending Ethereum into the world of institutional finance, turning it into infrastructure banks can actually run on. That’s the reason why we always say ZK is the endgame.
