Fields

creation_time: UnixTimestamp

when the network (bootstrap validator) was started relative to the UNIX Epoch

accounts: BTreeMap<Pubkey, Account>

initial accounts

native_instruction_processors: Vec<(String, Pubkey)>

built-in programs

rewards_pools: BTreeMap<Pubkey, Account>

accounts for network rewards, these do not count towards capitalization

ticks_per_slot: u64

unused: u64

poh_config: PohConfig

network speed configuration

__backwards_compat_with_v0_23: u64

this field exists only to ensure that the binary layout of GenesisConfig remains compatible with the Solana v0.23 release line

fee_rate_governor: FeeRateGovernor

transaction fee config

rent: Rent

rent config

inflation: Inflation

inflation config

epoch_schedule: EpochSchedule

how slots map to epochs

cluster_type: ClusterType

network runlevel

evm_root_hash: H256

Initial data for evm part

evm_chain_id: u64

EVM chain id
