"gasLimit": "0x0000000000001388",
"difficulty": "0x0000000000000001",
"mixHash": "0x0000000000000000000000000000000000000000000000000000000000000000",

}
},
"bootnodes": []
}

Data Directory

When executing the data-dir flag, a test-chain folder is generated. The folder structure consists of the following sub-folders:

  • blockchain - Stores the LevelDB for blockchain objects
  • trie - Stores the LevelDB for the Merkle tries
  • keystore - Stores private keys for the client. This includes the libp2p private key and the sealing/validator private key
  • consensus - Stores any consensus information that the client might need while working
