Types ¶

type Path ¶

type Path interface {
	GetCommitmentType() Type
	String() string
	IsEmpty() bool
}

Path implements spec:CommitmentPath. A path is the additional information provided to the verification function.

type Prefix ¶

type Prefix interface {
	GetCommitmentType() Type
	Bytes() []byte
	IsEmpty() bool
}

Prefix implements spec:CommitmentPrefix. Prefix represents the common "prefix" that a set of keys shares.

type Proof ¶

type Proof interface {
	GetCommitmentType() Type
	VerifyMembership(Root, Path, []byte) error
	VerifyNonMembership(Root, Path) error
	IsEmpty() bool

	ValidateBasic() error
}

Proof implements spec:CommitmentProof. Proof can prove whether the key-value pair is a part of the Root or not. Each proof has designated key-value pair it is able to prove. Proofs includes key but value is provided dynamically at the verification time.

type Root ¶

type Root interface {
	GetCommitmentType() Type
	GetHash() []byte
	IsEmpty() bool
}

Root implements spec:CommitmentRoot. A root is constructed from a set of key-value pairs, and the inclusion or non-inclusion of an arbitrary key-value pair can be proven with the proof.

type Type ¶

type Type byte

Type defines the type of the commitment

const (
	Merkle Type = iota + 1 // 1
)

Registered commitment types

func (Type) String ¶

func (ct Type) String() string
