const BlockMessageLimit = 10000

TODO: If this is gonna stay, it should move to specs-actors

const BlsSignatureCacheSize = 40000

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

const BootstrapPeerThreshold = 4

BootstrapPeerThreshold is the minimum number peers we need to track for a sync worker to start

const BootstrappersFile = "mainnet.pi"

const BreezeGasTampingDuration = 120

const BuildVersion = "1.11.3-rc2"

BuildVersion is the local build version

const UpgradeKumquatHeight = 170000

const UpgradeLiftoffHeight = 148888

This signals our tentative epoch for mainnet launch. Can make it later, but not earlier. Miners, clients, developers, custodians all need time to prepare. We still have upgrades and state changes to do, but can happen after signaling timing here.

const VerifSigCacheSize = 32000

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

const WRatioDen = uint64(2)

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

Variables

	DefaultFDLimit uint64 = 16 << 10
	MinerFDLimit   uint64 = 100_000
)

var BlocksPerEpoch = uint64(builtin2.ExpectedLeadersPerEpoch)

Blocks (e)

var BuildType 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.

var CurrentCommit string

var Devnet = true

var DisableBuiltinAssets = false

DisableBuiltinAssets disables the resolution of go.rice boxes that store built-in assets, such as proof parameters, bootstrap peers, genesis blocks, etc.

When this value is set to true, it is expected that the user will provide any such configurations through the Lotus API itself.

This is useful when you're using Lotus as a library, such as to orchestrate test scenarios, or for other purposes where you don't need to use the defaults shipped with the binary.

For this flag to be effective, it must be enabled _before_ instantiating Lotus.
