Is a continuation of the original Ethereum blockchain - the classic version preserving untampered history; free from external interference and subjective tampering of transactions.

Good news for all members of Ethereum Classic community. New version of ETC Geth has been released.

Let's check what's new!


  • Newly configurable in external chain.json:

    • "state": { "startingNonce": NUMBER } - optional (mainnet: 0, morden: 1048576) - "dirty" starting world state
    • "network": NUMBER - required (mainnet: 1, morden: 2) - network id used to identify valid peers
    • "consensus": STRING - optional (default: "ethash", optional: "ethash-test") - specify smaller and faster pow algorithm, e.g. --dev mode sets "ethash-test". See cmd/geth/config/*.json for updated examples.
  • Dev mode (--dev) made compatible with --chain
  • debug_AccountExist method added to RPC and web3 extension methods 
  • Additional Morden testnet bootnodes
  • Add listen for SIGTERM to stop more gracefully, if possible

Distributed database that is used to maintain a continuously growing list of records, called blocks.


  • Nightly and tagged release distribution builds made available at (instead of Bintray)
  • Option--chain <chainIdentifier|mychain.json> - specify chain identifier or path to JSON configuration file


  • geth attach command uses chain subdirectory schema by default, e.g. datadir/mainnet/geth.ipcinstead of datadir/geth.ipc
  • Sometimes ungraceful stopping on SIGTERM, potentially causing corrupted chaindata
  • PublicKey method for protected transactions with malformed chain id causing SIGSEGV
  • Concurrent map read/writes for State Objects
  • Ignore reported neighbors coming from non-reserved addresses; prevents irrelevant discovery attempts on local and reserved IP's
  • RLP-decoded transactions include EIP155 signer if applicable
