zkSync Era (ZK)

What is the zkSync Era Blockchain?​

Here are 5 key points about the zkSync Era Blockchain:

  • Zero-Knowledge Rollups: zkSync Era employs zero-knowledge rollup technology to enhance scalability and reduce transaction costs. By bundling multiple transactions off-chain and submitting them to Ethereum with validity proofs, zkSync Era ensures faster and cheaper transactions while maintaining the security of the Ethereum network.

  • EVM Compatibility: zkSync Era is fully compatible with Ethereum's Virtual Machine (EVM), allowing developers to deploy existing Ethereum dApps with minimal modifications. This compatibility facilitates seamless migration and interaction between zkSync Era and Ethereum, leveraging the same tools, libraries, and languages.

  • Account Abstraction and Paymasters: The platform introduces advanced features like account abstraction and paymasters, which simplify user interactions and enhance network performance. Account abstraction allows for more flexible and complex transaction execution, while paymasters enable fee payments in ERC20 tokens, making transactions more accessible and user-friendly.

  • High Throughput and Low Latency: zkSync Era is designed to handle a high volume of transactions with a peak load capacity of up to 2,000 transactions per second (TPS). This significantly improves transaction speed and efficiency, alleviating congestion on the Ethereum network.

  • Interoperability with ZK Chains: zkSync Era supports a network of interconnected ZK Chains, enabling efficient cross-chain communication and interoperability. This setup allows for the seamless transfer of assets and information across different chains, enhancing the scalability and utility of the blockchain ecosystem.

How to Get zkSync Era and zkSync Era ETH?​

Here are some ways to acquire some zkSync (ZK) and zkSync Ethereum (ETH):

  • Buy zkSync Era (ZK) and ZK Ethereum (ETH) directly on the Gem Wallet app. (TBA)
  • Receive ZK and ZK ETH with the unique zkSync Era address on the Gem Wallet app.
  • Swap ERC20 tokens to ZK ETH. This requires that you already have ZK ETH on your wallet to pay for fees.

Transaction Fees on zkSync Era Network​

The fees on zkSync Era are summarized as follows:

  • zkSync Era offers significantly lower transaction fees compared to Ethereum. These fees are among the lowest compared to other Layer 2 solutions like Arbitrum and Optimism, making zkSync Era a cost-effective option for users​.
  • The zkSync Era achieves lower fees by processing multiple transactions off-chain and then submitting a single batch as a validity proof to the Ethereum mainnet.
  • Users conducting transactions on the zkSync Era network pay fees denominated in zkSync Ethereum (ETH).
