About Core Blockchain Mainnet
Core Blockchain Mainnet is a Layer-1 blockchain network identified by chain ID 1116, developed by Core DAO. It utilizes the native token, Core Blockchain Native Token (CORE), with 18 decimal places. The network is designed to be Bitcoin's complementary and hyper-scalable smart contract platform, leveraging Bitcoin-native CLTV timelocks and Bitcoin mining hash power.
The Core Blockchain Mainnet supports decentralized applications (dApps) and decentralized finance (DeFi) services, enabling developers to build and deploy smart contracts within its ecosystem. The network offers several RPC endpoints for interaction.
For transaction monitoring and network exploration, Core Scan serves as the official blockchain explorer, providing users with access to block and transaction data.
In November 2025, the Hermes Hardfork was activated on the Core Mainnet, introducing features such as faster transaction finality and enhanced validator operations.
