go-etchash
Etchash go module intended for use by core-pool (and open-ethereum-pool).
- supports etchash, ethash & ubqhash
usage (etchash)
var ecip1099FBlockClassic uint64 = 11700000 // classic mainnet
var ecip1099FBlockMordor uint64 = 2520000 // mordor testnet
var hasher = etchash.New(&ecip1099FBlockMordor, nil)
if hasher.Verify(block) {
...
}
usage (ethash)
var hasher = etchash.New(nil, nil)
if hasher.Verify(block) {
...
}
usage (ubqhash)
var uip1FEpoch uint64 = 22 // ubiq mainnet
var hasher = etchash.New(nil, &uip1FEpoch)
if hasher.Verify(block) {
...
}

Overview ¶
Package ethash implements the ethash proof-of-work consensus engine.

Variables ¶
var ErrInvalidDumpMagic = errors.New("invalid dump magic")
Functions ¶
func MakeDataset ¶
MakeDataset generates a new ethash dataset and optionally stores it to disk.
Types ¶
type Config ¶
type Config struct {
CacheDir string
CachesInMem int
CachesOnDisk int
CachesLockMmap bool
DatasetDir string
DatasetsInMem int
DatasetsOnDisk int
DatasetsLockMmap bool
PowMode Mode
// When set, notifications sent by the remote sealer will
// be block header JSON objects instead of work package arrays.
NotifyFull bool
Log log.Logger `toml:"-"`
}
Config are the configuration parameters of the ethash.
type Ethash ¶
type Ethash struct {
// contains filtered or unexported fields
}
Ethash is a consensus engine based on proof-of-work implementing the ethash algorithm.
func New ¶
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.
func NewFakeDelayer ¶
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 Ethereum consensus rules.
func NewFakeFailer ¶
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 Ethereum consensus rules.
func NewFaker ¶
func NewFaker() *Ethash
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 Ethereum consensus rules.
func NewFullFaker ¶
func NewFullFaker() *Ethash
NewFullFaker creates an ethash consensus engine with a full fake scheme that accepts all blocks as valid, without checking any consensus rules whatsoever.
func NewShared ¶
func NewShared() *Ethash
NewShared creates a full sized ethash PoW shared between all requesters running in the same process.
func NewTester ¶
NewTester creates a small sized ethash PoW scheme useful only for testing purposes.
func (*Ethash) APIs ¶
func (ethash *Ethash) APIs(chain consensus.ChainHeaderReader) []rpc.API
APIs implements consensus.Engine, returning the user facing RPC APIs.
func (*Ethash) Hashrate ¶
Hashrate implements PoW, returning the measured rate of the search invocations per second over the last minute. Note the returned hashrate includes local hashrate, but also includes the total hashrate of all remote miner.
func (*Ethash) SetThreads ¶
SetThreads updates the number of mining threads currently enabled. Calling this method does not start mining, only sets the thread count. If zero is specified, the miner will use all cores of the machine. Setting a thread count below zero is allowed and will cause the miner to idle, without any work being done.
func (*Ethash) StopRemoteSealer ¶
StopRemoteSealer stops the remote sealer
