Deployment Parameters
Constructor Parameters
Here we will describe the Fuel contract's constructor parameters.
field name | description |
---|---|
operator | address ; The primary operator of the Fuel rollup. This account receives priority access on including roots in blocks production, however, anyone else may use roots with a delay specified by the submissionDelay parameter. |
finalizationDelay | uint256 ; The time to finalization in Ethereum blocks. |
submissionDelay | uint256 ; The number of Ethereum blocks a non-operator must wait before using a root in a block. |
penaltyDelay | uint256 ; The delay which the operator will face if they commit Fraud, until the time they may come back online as the primary operator. |
bondSize | uint256 ; The bond size required for block production, in wei. |
name | string ; The name string used for contract identification and EIP-712 hashing. |
version | string ; The version of the contract used for identification and EIP-712 hashing. |
chainId | uint256 ; The Ethereum network chain identifier used for identification, replay attack protection, and EIP-712 hashing. |
genesis | bytes32 ; The registered genesis block hash. This property is simply for vanity and can be set to any value as the minimum referenced block is always > 0. |
Deploying in Operated Mode
If you would like to deploy a Fuel chain in operated mode, use non-zero values for operator
and submissionDelay
.
Deploying in Un-operated Mode
If you would like to deploy Fuel in un-operated mode, where anyone may submit blocks at any time, use zero values for operator
and submissionDelay
.
Finalization Delays
In any optimistic rollup, finalization delay is a critical security parameter. A longer value provides more robustness against miner censorship attacks, but will result in longer withdrawals.
We recommend 1 week at the minimum, or 2 weeks on the higher end, to protect against both chain congestion attacks and censorship attacks.
