Chain ID

Official Chain IDs

The latest Chain ID (i.e highest Version Number) is the latest version of the software and mainnet.

Name	Chain ID	Identifier	EIP155 Number	Version Number
Metanovaverse	mnova_10096-1	mnova	10096	1

The Chain Identifier

Every chain must have a unique identifier or chain-id. Tendermint requires each application to define its own chain-id in the genesis.json fields. However, in order to comply with both EIP155 and Cosmos standard for chain upgrades, Metanovaverse-compatible chains must implement a special structure for their chain identifiers.

Structure

The Metanovaverse Chain ID contains 3 main components

• Identifier: Unstructured string that defines the name of the application.

• EIP155 Number: Immutable EIP155 CHAIN_ID that defines the replay attack protection number.

• Version Number: Is the version number (always positive) that the chain is currently running. This number MUST be incremented every time the chain is upgraded or forked in order to avoid network or consensus errors.

Format

The format for specifying and Metanovaverse-compatible chain-id in genesis is the following:

{identifier}_{EIP155}-{version}
