Name | Chain ID | Identifier | EIP155 Number | Version Number |
---|---|---|---|---|
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, BlockX-compatible chains must implement a special structure for their chain identifiers.
The BlockX 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.
The format for specifying and BlockX-compatible chain-id in genesis is the following:
BlockX
blockx_100-1
blockx
100
1
Atlantis
blockx_50-1
blockx
