About Harmony Mainnet Shard 0
Harmony Mainnet Shard 0 is a blockchain network identified by chain ID 1666600000. It utilizes ONE as its native token, with 18 decimal places. This shard serves as the Beacon Chain, responsible for transmitting information between different shards in the Harmony network. It operates under the Effective Proof-of-Stake (EPoS) mechanism, which aims to reduce centralization and distribute rewards fairly among validators. The network employs a Fast Byzantine Fault Tolerance (FBFT) consensus algorithm, achieving block finality in approximately 2 seconds. Harmony's sharding approach divides the network into multiple shards, each processing transactions and maintaining its own state, thereby enhancing scalability and parallel processing capabilities. The native token, ONE, is used for transaction fees and staking within the network.
