chunk_producer_assignment_changes_limit: u64

Limits the number of shard changes in chunk producer assignments, if algorithm is able to choose assignment with better balance of number of chunk producers for shards.

chunk_producer_kickout_threshold: u8

Threshold for kicking out chunk producers, between 0 and 100.

Epoch length counted in block heights.

fishermen_threshold: String

Fishermen stake threshold.

gas_limit: u64

Initial gas limit.

gas_price_adjustment_rate: [i32; 2]

Gas price adjustment rate

genesis_height: u64

Height of genesis block.

genesis_time: DateTime<Utc>

Official time of blockchain start.

max_gas_price: String

max_inflation_rate: [i32; 2]

Maximum inflation on the total supply every epoch.

max_kickout_stake_perc: u8

Max stake percentage of the validators we will kick out.

min_gas_price: String

minimum_validators_per_shard: u64

The minimum number of validators each shard must have

num_block_producer_seats: u64

Number of block producer seats at genesis.

num_block_producer_seats_per_shard: Vec<u64>

Defines number of shards and number of block producer seats per each shard at genesis. Note: not used with protocol_feature_chunk_only_producers – replaced by minimum_validators_per_shard Note: not used before as all block producers produce chunks for all shards

num_blocks_per_year: u64

Expected number of blocks per year

num_chunk_only_producer_seats: u64

Deprecated.

num_chunk_producer_seats: u64

Number of chunk producers. Don’t mess it up with chunk-only producers feature which is deprecated.

num_chunk_validator_seats: u64

shard_layout: ShardLayout

Layout information regarding how to split accounts to shards

shuffle_shard_assignment_for_chunk_producers: bool

If true, shuffle the chunk producers across shards. In other words, if the shard assignments were [S_0, S_1, S_2, S_3] where S_i represents the set of chunk producers for shard i, if this flag were true, the shard assignments might become, for example, [S_2, S_0, S_3, S_1].

target_validator_mandates_per_shard: u64

Number of target chunk validator mandates for each shard.

total_supply: String

Total supply of tokens at genesis.

transaction_validity_period: u64

Number of blocks for which a given transaction is valid

use_production_config: bool

This is only for test purposes. We hard code some configs for mainnet and testnet in AllEpochConfig, and we want to have a way to test that code path. This flag is for that. If set to true, the node will use the same config override path as mainnet and testnet.

validators: Vec<AccountInfo>

List of initial validators.
