AB Core Technical Information

Basic Information​

Key Differences Between AB Core and Ethereum​

AB Core is fully compatible with Ethereum, supporting standard EVM contracts and developer tools.

However, AB Core currently supports up to the Berlin hard fork and does not implement EIP-1559 (BaseFee and gas burning) introduced in the London upgrade, nor any subsequent upgrades such as Shanghai or Dencun.

  • Token Precision:
    The smallest unit of AB is ISSAC.
    1 AB = 1,000,000,000,000,000,000 ISSAC.

  • Block Interval:
    3 seconds.

  • Number of Confirmations for Transaction Security:
    A transaction is considered secure after 20 block confirmations.
