Types ¶
type Block ¶
Block defines the structure of Optimint block.
func (*Block) MarshalBinary ¶
MarshalBinary encodes Block into binary form and returns it.
func (*Block) UnmarshalBinary ¶
UnmarshalBinary decodes binary form of Block into object.
func (*Block) ValidateBasic ¶
ValidateBasic performs basic validation of a block.
type Commit ¶
type Commit struct {
Height uint64
HeaderHash [32]byte
Signatures []Signature // most of the time this is a single signature
}
Commit cointains evidence of block creation.
func (*Commit) MarshalBinary ¶
MarshalBinary encodes Commit into binary form and returns it.
func (*Commit) UnmarshalBinary ¶
UnmarshalBinary decodes binary form of Commit into object.
func (*Commit) ValidateBasic ¶
ValidateBasic performs basic validation of a commit.
type Data ¶
type Data struct {
Txs Txs
IntermediateStateRoots IntermediateStateRoots
Evidence EvidenceData
}
Data defines Optimint block data.
func (*Data) MarshalBinary ¶
MarshalBinary encodes Data into binary form and returns it.
func (*Data) ValidateBasic ¶
ValidateBasic performs basic validation of block data. Actually it's a placeholder, because nothing is checked.
type Evidence ¶
type Evidence interface {
ABCI() []abci.Evidence // forms individual evidence to be sent to the application
Bytes() []byte // bytes which comprise the evidence
Hash() []byte // hash of the evidence
Height() int64 // height of the infraction
String() string // string format of the evidence
Time() time.Time // time of the infraction
ValidateBasic() error // basic consistency check
}
Evidence represents any provable malicious activity by a validator. Verification logic for each evidence is part of the evidence module.
type EvidenceData ¶
type EvidenceData struct {
Evidence []Evidence
}
EvidenceData defines how evidence is stored in block.
type Header ¶
type Header struct {
// Block and App version
Version Version
// NamespaceID identifies this chain e.g. when connected to other rollups via IBC.
// TODO(ismail): figure out if we want to use namespace.ID here instead (downside is that it isn't fixed size)
// at least extract the used constants (32, 8) as package variables though.
NamespaceID [8]byte
Height uint64
Time uint64 // time in tai64 format
// prev block info
LastHeaderHash [32]byte
// hashes of block data
LastCommitHash [32]byte // commit from aggregator(s) from the last block
DataHash [32]byte // Block.Data root aka Transactions
ConsensusHash [32]byte // consensus params for current block
AppHash [32]byte // state after applying txs from the current block
// Root hash of all results from the txs from the previous block.
// This is ABCI specific but smart-contract chains require some way of committing
// to transaction receipts/results.
LastResultsHash [32]byte
// Note that the address can be derived from the pubkey which can be derived
// from the signature when using secp256k.
// We keep this in case users choose another signature format where the
// pubkey can't be recovered by the signature (e.g. ed25519).
ProposerAddress []byte // original proposer of the block
// Hash of block aggregator set, at a time of block creation
AggregatorsHash [32]byte
}
Header defines the structure of Optimint block header.
func (*Header) MarshalBinary ¶
MarshalBinary encodes Header into binary form and returns it.
func (*Header) UnmarshalBinary ¶
UnmarshalBinary decodes binary form of Header into object.
func (*Header) ValidateBasic ¶
ValidateBasic performs basic validation of a header.
type IntermediateStateRoots ¶
type IntermediateStateRoots struct {
RawRootsList [][]byte
}
IntermediateStateRoots describes the state between transactions. They are required for fraud proofs.
type TxProof ¶
type TxProof struct {
RootHash tmbytes.HexBytes `json:"root_hash"`
Data Tx `json:"data"`
Proof merkle.Proof `json:"proof"`
}
TxProof represents a Merkle proof of the presence of a transaction in the Merkle tree.
