Chain ID

A chain ID is a unique identifier that represents a blockchain network. We use it to distinguish different blockchain networks from each other and to ensure that transactions and messages are sent to the correct network. Paxeer Network network follows the format of identifier_EIP155-version format.

Official Chain IDs

:::tip NOTE: The latest Chain ID (i.e highest Version Number) is the latest version of the software and mainnet. Also note, that the following upgrades technically did not require a Chain ID change:
  • Paxeer Network_9001-1 -> Paxeer Network_9001-2
  • hyperpax_125-3 -> hyperpax_125-4 :::

No public testnet available. Developers should use local development networks. See the Single Node guide for setting up a local development environment.

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, to comply with both EIP-155 and Cosmos standard for chain upgrades, Paxeer Network-compatible chains must implement a special structure for their chain identifiers.

Structure

The Paxeer Network Chain ID contains 3 main components
  • Identifier: Unstructured string that defines the name of the application.
  • EIP-155 Number: Immutable EIP-155 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 to avoid network or consensus errors.

Format

The format for specifying and Paxeer Network compatible chain-id in genesis is the following:
{identifier}_{EIP155}-{version}
The following table provides an example where the second row corresponds to an upgrade from the first one:
