Constants

const (
	DefaultConfidence          = uint64(5)
	DefaultMessageWaitLookback = abi.ChainEpoch(100) // in most cases, this should be enough to avoid races.
	LookbackNoLimit            = abi.ChainEpoch(-1)
)

const (
	BlockGasLimit          = 10_000_000_000
	BlockGasTarget         = BlockGasLimit / 2
	BaseFeeMaxChangeDenom  = 8 // 12.5%
	InitialBaseFee         = 100e6
	MinimumBaseFee         = 100
	PackingEfficiencyNum   = 4
	PackingEfficiencyDenom = 5
)

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

const (
	NoTimeout = math.MaxInt64
	NoHeight  = abi.ChainEpoch(-1)
)

const (
	WRatioNum = int64(1)
	WRatioDen = uint64(2)
)

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

const (
	FilBase               = uint64(2_000_000_000)
	FilAllocStorageMining = uint64(1_100_000_000)
)

const (
	FilecoinPrecision = uint64(1_000_000_000_000_000_000)
	FilReserved       = uint64(300_000_000)
)

const (
	VerifSigCacheSize = 32000
	Finality          = policy.ChainFinality
)

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

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 = "1.16.0"

BuildVersion is the local build version, set by build system

const DefaultHashFunction = uint64(mh.BLAKE2B_MIN + 31)

The multihash function identifier to use for content addresses.

const DevSealProofType = abi.RegisteredSealProof_StackedDrg2KiBV1

const ForkLengthThreshold = Finality

Epochs

const MainNetBlockDelaySecs = uint64(builtin0.EpochDurationSeconds)

const MessageConfidence = uint64(5)

Epochs

const StringEmpty = ""

const TestNetworkVersion = network.Version23

const TicketRandomnessLookback = abi.ChainEpoch(1)

Epochs

Variables

var (
	DevRegisteredWinningPoStProof = abi.RegisteredPoStProof_StackedDrgWinning2KiBV1
	DevRegisteredWindowPoStProof  = abi.RegisteredPoStProof_StackedDrgWindow2KiBV1
)

var (
	InitialRewardBalance *big.Int
	InitialFilReserved   *big.Int
)

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 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 FevmEnableEthRPC = os.Getenv("VENUS_FEVM_ENABLEETHRPC") == "1"

FevmEnableEthRPC enables eth rpc, and enables storing a mapping of eth transaction hashes to filecoin message Cids.

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

FiveHundredTwelveMiBSectorSize contain 512MiB after sealing.

var InsecurePoStValidation = os.Getenv("INSECURE_POST_VALIDATION") == "1"

InsecurePoStValidation use to attach debug

var NoMigrationResultCache = os.Getenv("VENUS_NO_MIGRATION_RESULT_CACHE") == "1"

NoMigrationResultCache will not use cached migration results

var NoSlashFilter = os.Getenv("VENUS_NO_SLASHFILTER") == "_yes_i_know_and_i_accept_that_may_loss_my_fil"

NoSlashFilter will not check whether the miner's block violates the consensus

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

ThirtyTwoGiBSectorSize contain 32GiB after sealing.
