zkSync is a Layer 2 protocol, designed to scale and enhance privacy on the Ethereum ecosystem. Additionally, it offers low-cost ETH and ERC20 token transfers, as well as features such as atomic swaps, limit orders, and integrated support for Layer 2 (L2) non-fungible tokens (NFTs). 

The network operates on a zk-Rollup architecture. zk-Rollups are off-chain scaling protocols that combine several transactions into batches to execute off the main chain. Each Rollup block produces a state transition zero-knowledge proof (SNARK) that is confirmed by the main chain contract. This proof confirms the legitimacy of every transaction in the Rollup block. Moreover, updates to the public data for each block are disseminated across the mainchain in a cost-efficient manner using calldata.

The zk-Rollup architecture ensures several key benefits:

• Rollup validators are unable to alter the state or misappropriate funds, setting it apart from Sidechains.
• Users have the ability to recover their funds from the Rollup regardless of the validators’ cooperation, thanks to the availability of data, a feature missing in Plasma.
• With the implementation of validity proofs, there’s no need for users or any other trusted entity to constantly monitor the Rollup blocks to detect fraud.

zkSync’s goal is to accelerate widespread crypto adoption to enhance individual autonomy. The protocol leverages a sophisticated zk-rollup design, incorporating an LLVM-based Solidity compiler, its own acclaimed GPU prover, and the forthcoming Redshift proof system developed by Matter Labs. This technology is designed to drastically lower the cost of an average transaction to just a small fraction of a cent.

The architecture of zkSync supports unlimited computational capacity in each block, paving the way for a new breed of dApps capable of processing far more data on-chain than was previously feasible. By restricting publications to final storage state updates, zkSync maximizes the benefits of cost-effective computation. This enables a range of enhancements, such as more frequent oracle updates, more economical transactions involving extensive input data, and substantially reduced costs for verifying zk-proofs.

Blast Integrates zkSync

Builders on zkSync can now securely access the network through Blast. Blast’s intuitive interface and comprehensive documentation make it easy for developers to swiftly set up custom API endpoints for both the zkSync Mainnet and Testnet. The platform allows for efficient management of multiple projects, offering high processing capabilities, rapid response times, and dependable performance. Embracing decentralization, Blast leverages the resources of dozens of node operators that participate in its protocol as Node Providers increasing availability through a highly distributed network secured by its own protocol. 

Blast offers specialized APIs that can be customized to suit particular project needs, in addition to a public API option. It supports both the zkSync Mainnet and Mantle Testnet, providing versatile solutions for developers.
