# Configurate

## Configuration

### Brief

* `compiler` \[TODO] choose which compiler to use
* `transactions` object of constructors arranged by contract file name
  * `limit` mainchain transaction limit
  * `depth` how many blocks to wait for to count transactions as complete in mainchain
  * `privateKey` default privatekey to use for all transactions with mainchain
  * `fromAddress` default address to use for all transactions with mainchain
* `subchain` subchain configs:
  * `limit` subchain transaction limit
  * `depth` how many blocks to wait for to count transactions as complete in subchain
  * `node` http-address to use for subchain
* `shard` object of http-address of mainchain arranged by shard
  * `1` http-address to use for shard 1 of mainchain
  * `2` http-address to use for shard 2 of mainchain
  * `3` http-address to use for shard 3 of mainchain
  * `4` http-address to use for shard 4 of mainchain
* `constructors`
  * `"StemRootchain.sol"` The constructor for subchain contract
* `addressBook` object of contract-address arranged by contract file name
  * `"StemRootchain.sol"` The subchain address

### More

#### `constructors`

The `"StemRootchain.sol"` field in `constructors` is matched to an array:

* \[0] abi array
* \[1] value array
* \[2] transaction amount when deploy

This is exactly as what [seele-cotnract-core](https://www.npmjs.com/package/seele-contract-core) requires. Refer to the example in appendix.

* `_subchainName`, (`bytes32`): strings hashed into
* `_genesisInfo`, (`bytes32[]`):
  * filled by `anc fill` option
* `_staticNodes`, (`bytes32[]`):
* `_creatorDeposit`, (`uint256`):
* `_ops`, (`address[]`):
  * `[0]` mintAccount (refer to StemCreation.sol)
  * `[1]` meltAccount (refer to StemCreation.sol)
* `_opsDeposits`, (`uint256[]`):
  * `[0]`: 0
  * `[1]`: 0
* `_refundAccounts`, (`address[]`):
  * `[0]`: `"0x0000000000000000000000000000000000000000"`
  * `[1]`: `"0x0000000000000000000000000000000000000000"`

#### `addressBook`

Delete the `"StemRootchain.sol"` field in `addressBook` and re-run `anc make -d` to re-deploy the StemRootchain.sol contract which essentially reuses the other addresses and updates the contract you're now focused on. The `"StemRootchain.sol"` field will contain the contract-address that all anc action assumes.

Similarly, to change more parameters like challenge period and relay periods, you would change them in the StemRootchain.sol file in your subchain project's `./src` directory, then you can delete the `"StemCreation.sol"` field along with `"StemRootchain.sol"` field to re-deploy your subchain.

#### `genesis`

`"rootaccounts"`: `"validators"`: equal to the constructors
