Genesis
=======
The genesis.json file in ``$TMHOME/config`` defines the initial TendermintCore
state upon genesis of the blockchain (`see
definition <https://github.com/tendermint/tendermint/blob/master/types/genesis.go>`__).
Fields
~~~~~~
- ``genesis_time``: Official time of blockchain start.
- ``chain_id``: ID of the blockchain. This must be unique for every
blockchain. If your testnet blockchains do not have unique chain IDs,
you will have a bad time.
- ``validators``:
- ``pub_key``: The first element specifies the pub\_key type. 1 ==
Ed25519. The second element are the pubkey bytes.
- ``power``: The validator's voting power.
- ``name``: Name of the validator (optional).
- ``app_hash``: The expected application hash (as returned by the
``Commit`` ABCI message) upon genesis. If the app's hash does not
match, a warning message is printed.
- ``app_state``: The application state (e.g. initial distribution of tokens).
