Abstract

In CAIP-2 a general blockchain identification scheme is defined. This is the implementation of CAIP-2 for Ergo network.

Specification

Blockchains in the “ergo” namespace are identified by their chain ID.

Chain ID is 32-character prefix from the hash of the genesis block of a given chain, in lowercase hex representation.

Syntax

The chain_id is a case-sensitive string in the form

chain_id:    namespace + ":" + reference
namespace:   ergo
reference:   32-character prefix from the hash of the genesis block

Resolution method

One can resolve chain ID by request info method on Ergo node API (see RPC Endpoints):

curl https://node.ergo.watch/info

JSON Response contains genesisBlockId field:

{
...
  "genesisBlockId" : "b0244dfc267baca974a4caee06120321562784303a8a688976ae56170e4d175b",
...
}

So chain ID for Mainnet is b0244dfc267baca974a4caee06120321.

Test Cases

This is a list of manually composed examples

# Ergo mainnet
ergo:b0244dfc267baca974a4caee06120321

# Ergo testnet
ergo:e7553c9a716bb3983ac8b0c21689a1f3
