Functions ¶
Types ¶
type CPUMiner ¶
type CPUMiner struct {
// contains filtered or unexported fields
}
CPUMiner provides concurrency-safe PoW worker group to solve hash puzzle Inspired by:
"S/Kademlia: A Practicable Approach Towards Secure Key-Based Routing" - Section 4.1. Secure nodeID assignment. - Figure 3. Static (left) and dynamic (right) crypto puzzles for nodeID generation.
func (*CPUMiner) ComputeBlockNonce ¶
func (miner *CPUMiner) ComputeBlockNonce( block MiningBlock, startNonce Uint256, difficulty int, ) (err error)
ComputeBlockNonce find nonce make HashBlock() match the MiningBlock Difficulty from the startNonce if interrupted or stopped highest difficulty nonce will be sent to the NonceCh
HACK(auxten): make calculation parallel.
type MiningBlock ¶
type MiningBlock struct {
Data []byte
// NonceChan is used to notify the got nonce
NonceChan chan NonceInfo
// Stop chan is used to stop mining and return the max difficult nonce
Stop chan struct{}
}
MiningBlock contains Data tobe mined.
type NonceInfo ¶
type NonceInfo struct {
Nonce Uint256
Difficulty int
Hash hash.Hash // Hash can be used as raw NodeID
}
NonceInfo contains nonce and the difficulty to the block.
type Uint256 ¶
type Uint256 struct {
A uint64 // Bits 63..0.
B uint64 // Bits 127..64.
C uint64 // Bits 191..128.
D uint64 // Bits 255..192.
}
Uint256 is an unsigned 256 bit integer.
func Uint256FromBytes ¶
Uint256FromBytes converts []byte to Uint256.
func (*Uint256) MarshalHash ¶
MarshalHash marshals for hash.
