Blockchain Specs

Quick specs of the IoTeX Blockchain
Block Time
5-Second Block Time
Action Confirmation
7.5 Seconds on average. The fastest possible confirmation time is 5 Seconds.
Action Finality
1-Block finality for all blockchain actions.
Transaction Validation
Randomized Delegated Proof of Stake (Roll-DPoS) 
Consensus Algorithm
Practical Byzantine Fault Tolerant (PBFT)
Chain IDs
A Chain ID is a unique number assigned to different, independent IoTeX Blockchains. For example, IoTeX Mainnet chain hasChain ID = 1, while IoTeX Testnet has Chain ID = 2. Chain IDs in IoTeX are used for security reasons by including them in transaction signatures to prevent transaction replay attacks on different networks.
List of IoTeX Chain ID's
All IoTeX-based blockchains should adopt this Chain ID Mechanism by replacing CHAIN ID with a different and unique value. All testnet, consortium, and any IoTeX-cloned chains are encouraged to do the same:
