CalcDifficulty is the difficulty adjustment algorithm.

CalcDifficultyFrontierU256 is the difficulty adjustment algorithm.

MakeDifficultyCalculatorU256 creates a difficultyCalculator with the given bomb-delay.

New creates a full sized ethash PoW scheme and starts a background thread for remote mining, also optionally notifying a batch of remote services of new work packages.

NewFakeDelayer creates a ethash consensus engine with a fake PoW scheme that accepts all blocks as valid, but delays verifications by some time, though they still have to conform to the Classzz consensus rules.

NewFakeFailer creates a ethash consensus engine with a fake PoW scheme that accepts all blocks as valid apart from the single one specified, though they still have to conform to the Classzz consensus rules.

NewFaker creates a ethash consensus engine with a fake PoW scheme that accepts all blocks' seal as valid, though they still have to conform to the Classzz consensus rules.

NewFullFaker creates an ethash consensus engine with a full fake scheme that accepts all blocks as valid, without checking any consensus rules whatsoever.

NewShared creates a full sized ethash PoW shared between all requesters running in the same process.

NewTester creates a small sized ethash PoW scheme useful only for testing purposes.

2048 520.

Block reward in wei for successfully mining a block.

Exported for fuzzing.

Ethash proof-of-work protocol constants.

API exposes ethash related methods for the RPC interface.

Config are the configuration parameters of the ethash.

Ethash is a consensus engine based on proof-of-work implementing the ethash algorithm.

Mode defines the type and amount of PoW verification an ethash engine makes.
