Constants

View Source 
const ConsensusMinerMinMiners = 3

Minimum number of registered miners for the minimum miner size limit to effectively limit consensus power.

View Source 
const (
	ErrTooManyProveCommits = exitcode.FirstActorSpecificExitCode + iota
)
View Source 
const GasOnSubmitVerifySeal = 34721049

GasOnSubmitVerifySeal is amount of gas charged for SubmitPoRepForBulkVerify This number is empirically determined

View Source 
const MaxMinerProveCommitsPerEpoch = 200

Maximum number of prove commits a miner can submit in one epoch

We bound this to 200 to limit the number of prove partitions we may need to update in a given epoch to 200.

To support onboarding 1EiB/year, we need to allow at least 32 prove commits per epoch.

Variables

View Source 
var ConsensusMinerMinPower = abi.NewStoragePower(10 << 40)

Minimum power of an individual miner to meet the threshold for leader election.

View Source 
var InitialQAPowerEstimatePosition = big.Mul(big.NewInt(750_000), big.NewInt(1<<30))

genesis power in bytes = 750,000 GiB

View Source 
var InitialQAPowerEstimateVelocity = big.Mul(big.NewInt(3_840), big.NewInt(1<<30))

max chain throughput in bytes per epoch = 120 ProveCommits / epoch = 3,840 GiB
