Hyperscalability: Welcome to the ERA of the ZK Stack!

ICYMI; zkSync recently published ZK Credo, a document outlining foundational principles for ZK technology and the growing importance of zero-knowledge in Web3.

We're excited to share a peek at their ZK Stack: a modular framework designed for building sovereign ZK-powered chains, known as Hyperchains. The ZK Stack empowers developers with unparalleled capabilities and flexibility.

Key Features of the ZK Stack

• Open Source: MIT/Apache licensed, free to use.

• Composability: Hyperchains can connect within a trustless network with low latency and shared liquidity.

• Modularity: Developers customize sequencers, DA modes, tokenomics, and more.

• Reliability: Maintains zkSync Era-level security and standards.

Use Cases for the ZK Stack

Gaming & Social Networks

Lightweight sequencers for dedicated app performance without congestion from unrelated dapps.

Exchange Appchains

Low-latency sequencing optimized for high-frequency trading, similar to dYdX.

Banks & Enterprises

Closed private chains with connectivity to the broader ecosystem.

Network of Applications

Applications interact seamlessly within Hyperchains, avoiding bridge-related trust assumptions.

Token-Centric Use Cases

Design Hyperchains optimized for specific tokens serving as the base currency of the system.

What Exactly is the ZK Stack?

The ZK Stack is a modular, open-source framework built on the zkSync Era codebase. It allows developers to create custom L2/L3 Hyperchains that:

• Operate independently while leveraging Ethereum L1 for liveness and security

• Interconnect through Hyperbridges for trustless, cost-effective interoperability

• Share provers and benefit from fractal scaling for hyperscalability

• Enable asynchronous cross-chain smart contract calls

• Retain sovereignty, with the ability to join or leave ecosystems freely

ZK Technology Superpowers in the Stack

• Enhanced UX: Native Account Abstraction with gasless calldata improves usability.

• Compression: ZK proofs reduce transaction costs (e.g., Oracle updates up to 1,000x cheaper).

• Low Cost: Optional zkPorter accounts provide ultra-low-cost alternatives for specific use cases.

Hyperscalability Unlocked

The ZK Stack enables developers to build sovereign Hyperchains that interoperate seamlessly:

• Shared provers and fractal scaling support limitless ecosystem growth

• Unfragmented liquidity network enables fast, trustless asset transfers

• Smart contracts communicate asynchronously across chains

• Sovereignty allows chains to transition between ecosystems with full control
