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.

Variables

	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.
