Types ¶
type CuckarooContext ¶
type CuckarooContext struct {
// contains filtered or unexported fields
}
CuckarooContext is a Cuckatoo cycle context. Only includes the verifier for now.
func NewCuckarooCtx ¶
func NewCuckarooCtx(chainType consensus.ChainType, edgeBits uint8, proofSize int) (*CuckarooContext, error)
NewCuckarooCtx instantiates a new CuckarooContext as a PowContext
func (*CuckarooContext) SetHeaderNonce ¶
func (c *CuckarooContext) SetHeaderNonce(header []uint8, nonce *uint32)
SetHeaderNonce sets the header nonce.
func (*CuckarooContext) Verify ¶
func (c *CuckarooContext) Verify(proof Proof) error
Verify verifies the Cuckatoo context.
type CuckaroodContext ¶
type CuckaroodContext struct {
// contains filtered or unexported fields
}
CuckaroodContext is a Cuckatoo cycle context. Only includes the verifier for now.
func NewCuckaroodCtx ¶
func NewCuckaroodCtx(chainType consensus.ChainType, edgeBits uint8, proofSize int) (*CuckaroodContext, error)
NewCuckaroodCtx instantiates a new CuckaroodContext as a PowContext. Note that this can't be moved in the PoWContext trait as this particular trait needs to be convertible to an object trait.

type CuckooParams ¶
type CuckooParams struct {
// contains filtered or unexported fields
}
CuckooParams is a utility struct to calculate commonly used Cuckoo parameters calculated from header, nonce, edge_bits, etc.
type PowContext ¶
type PowContext interface {
// Sets the header along with an optional nonce at the end solve: whether to
// set up structures for a solve (true) or just validate (false)
SetHeaderNonce(header []uint8, nonce *uint32)
// Verify a solution with the stored parameters
Verify(proof Proof) error
}
PowContext is a generic interface for a solver/verifier providing common interface into Cuckoo-family PoW
func NoCuckarooCtx ¶
func NoCuckarooCtx() (PowContext, error)
NoCuckarooCtx error returned for cuckaroo request beyond HardFork4
type Proof ¶
type Proof struct {
// Power of 2 used for the size of the cuckoo graph
EdgeBits uint8
// The nonces
Nonces []uint64
}
Proof is a Cuck(at)oo Cycle proof of work, consisting of the edge_bits to get the graph size (i.e. the 2-log of the number of edges) and the nonces of the graph solution. While being expressed as u64 for simplicity, nonces a.k.a. edge indices range from 0 to (1 << edge_bits) - 1
The hash of the `Proof` is the hash of its packed nonces when serializing them at their exact bit size. The resulting bit sequence is padded to be byte-aligned.
type ProofOfWork ¶
type ProofOfWork struct {
// Total accumulated difficulty since genesis block
TotalDifficulty uint64
// Variable difficulty scaling factor fo secondary proof of work
SecondaryScaling uint32
// Nonce increment used to mine this block.

}
ProofOfWork is a block header information pertaining to the proof of work
func (*ProofOfWork) EdgeBits ¶
func (p *ProofOfWork) EdgeBits() uint8
EdgeBits is the edge bits used for the cuckoo cycle size on this proof
func (*ProofOfWork) IsPrimary ¶
func (p *ProofOfWork) IsPrimary() bool
IsPrimary is whether this proof of work is for the primary algorithm (as opposed / to secondary). Only depends on the edge_bits at this time.
func (*ProofOfWork) IsSecondary ¶
func (p *ProofOfWork) IsSecondary() bool
IsSecondary is whether this proof of work is for the secondary algorithm (as opposed / to primary). Only depends on the edge_bits at this time.
