Constants

const AllowableClockDriftSecs = uint64(1)

const BaseFeeMaxChangeDenom = 8 // 12.5%

const BlockGasLimit = 10_000_000_000

BlockGasLimit is the maximum amount of gas that can be used to execute messages in a single block.

const BlockGasTarget = BlockGasLimit / 2

const BlockMessageLimit = 10000

const BlsSignatureCacheSize = 40000

assuming 4000 messages per round, this lets us not lose any messages across a 10 block reorg.

const BuildVersion = "1.6.0-rc2"

BuildVersion is the local build version, set by build system

const DefaultConfidence = uint64(5)

const DefaultHashFunction = uint64(mh.BLAKE2B_MIN + 31)

The multihash function identifier to use for content addresses.

const DefaultMessageWaitLookback = abi.ChainEpoch(100) // in most cases, this should be enough to avoid races.

const DevSealProofType = abi.RegisteredSealProof_StackedDrg2KiBV1

const FilAllocStorageMining = uint64(1_100_000_000)

const FilBase = uint64(2_000_000_000)

const FilReserved = uint64(300_000_000)

const FilecoinPrecision = uint64(1_000_000_000_000_000_000)

const Finality = policy.ChainFinality

const ForkLengthThreshold = Finality

Epochs

const InitialBaseFee = 100e6

const LookbackNoLimit = abi.ChainEpoch(-1)

const MainNetBlockDelaySecs = uint64(builtin0.EpochDurationSeconds)

const MessageConfidence = uint64(5)

Epochs

const MinimumBaseFee = 100

const NewestNetworkVersion = network.Version16

const NoHeight = abi.ChainEpoch(-1)

const NoTimeout = math.MaxInt64

const PackingEfficiencyDenom = 5

const PackingEfficiencyNum = 4

const PropagationDelaySecs = uint64(6)

const StringEmpty = ""

const TicketRandomnessLookback = abi.ChainEpoch(1)

Epochs

const VerifSigCacheSize = 32000

Size of signature verification cache 32k keeps the cache around 10MB in size, max

const WRatioDen = uint64(2)

const WRatioNum = int64(1)

constants for Weight calculation The ratio of weight contributed by short-term vs long-term factors in a given round

Variables

var Clock = clock.New()

Clock is the global clock for the system. In standard builds, we use a real-time clock, which maps to the `time` package.

Tests that need control of time can replace this variable with clock.NewMock(). Always use real time for socket/stream deadlines. todo move this clock to clock package. constant package should refer other as little as possible

var CurrentCommit string

var DefaultCidBuilder = cid.V1Builder{Codec: cid.DagCBOR, MhType: DefaultHashFunction}

A builder for all blockchain CIDs. Note that sector commitments use a different scheme.

var DevRegisteredSealProof = abi.RegisteredSealProof_StackedDrg2KiBV1

just for test

var DevRegisteredWindowPoStProof = abi.RegisteredPoStProof_StackedDrgWindow2KiBV1

var DevRegisteredWinningPoStProof = abi.RegisteredPoStProof_StackedDrgWinning2KiBV1

var DevSectorSize abi.SectorSize

DevSectorSize is a tiny sector useful only for testing.

var EightMiBSectorSize = abi.SectorSize(1 << 23)

EightMiBSectorSize contains 8MiB after sealing.

var ExpectedLeadersPerEpoch = builtin0.ExpectedLeadersPerEpoch

expect blocks number in a tipset

var FiveHundredTwelveMiBSectorSize = abi.SectorSize(512 << 20)

FiveHundredTwelveMiBSectorSize contain 512MiB after sealing.

var InitialFilReserved *big.Int

var InitialRewardBalance *big.Int

var InsecurePoStValidation = false

todo move this value to config

var ThirtyTwoGiBSectorSize = abi.SectorSize(1 << 35)

ThirtyTwoGiBSectorSize contain 32GiB after sealing.
