Origins and Development History

Birth Background

zkSync was created by Matter Labs in 2024 to solve Ethereum's scalability challenges. It emerged during the ongoing blockchain scaling debate, aiming to provide fast and cost-effective transactions while maintaining Ethereum's security. zkSync's launch brought new possibilities for DeFi applications and users seeking efficient blockchain interactions.

Important Milestones

  • 2024: Mainnet launch, achieving high throughput and low-cost transactions.
  • 2025: Major upgrade introducing enhanced privacy features and cross-chain interoperability.
  • 2025: Adoption by various DeFi protocols, pushing the price to $0.367.
  • 2025: Ecosystem explosion, with the number of DeFi and NFT platforms leveraging zkSync surging.

With support from the Matter Labs team and community, zkSync continues to optimize its technology, security, and real-world applications.

How Does zkSync Work?

No Central Control

zkSync operates on a decentralized network of computers (nodes) globally, free from control by banks or governments. These nodes collaborate to validate transactions, ensuring system transparency and attack resistance, granting users greater autonomy and enhancing network resilience.

Blockchain Core

zkSync's blockchain is a public, immutable digital ledger recording every transaction. Transactions are grouped into blocks and linked through cryptographic hashes, forming a secure chain. Anyone can view the records, establishing trust without intermediaries. Zero-Knowledge Rollups further enhance performance by batching multiple transactions off-chain and submitting cryptographic proofs on-chain.

Ensuring Fairness

zkSync employs a Zero-Knowledge Proof (ZKP) consensus mechanism to validate transactions and prevent fraudulent activities like double-spending. Validators maintain network security by generating and verifying zero-knowledge proofs, receiving ZK tokens as rewards. Its innovation includes higher transaction throughput and lower fees compared to the Ethereum base layer.

Secure Transactions

zkSync uses public-private key encryption to protect transactions:

  • Private keys (like secret passwords) are used to sign transactions
  • Public keys (like account numbers) are used to verify ownership

This mechanism ensures fund security, with transactions remaining pseudonymous. Additionally, zkSync implements advanced cryptographic techniques to enhance privacy and security while maintaining compatibility with Ethereum.
