Variables ¶
var InitStateVersion = tmstate.Version{ Consensus: tmversion.Consensus{ Block: version.BlockProtocol, App: 0, }, Software: version.TMCoreSemVer, }
InitStateVersion sets the Consensus.Block and Software versions, but leaves the Consensus.App version blank. The Consensus.App version will be set during the Handshake, once we hear from the app what protocol version it is running.
Functions ¶
This section is empty.
Types ¶
type Batch ¶
Batch defines a struct for block aggregation for support of batching. TODO: maybe change to BlockBatch
func (*Batch) MarshalBinary ¶
MarshalBinary encodes Batch into binary form and returns it.
func (*Batch) UnmarshalBinary ¶
UnmarshalBinary decodes binary form of Batch into object.
type Block ¶
Block defines the structure of Dymint 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 Dymint 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 Dymint 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 State ¶
type State struct { Version tmstate.Version // immutable ChainID string InitialHeight int64 // should be 1, not 0, when starting from height 1 // LastBlockHeight=0 at genesis (ie. block(H=0) does not exist) LastBlockHeight int64 LastBlockID types.BlockID LastBlockTime time.Time // SLStateIndex identifies the Settlement Layer state index we're synced with SLStateIndex uint64 // In the MVP implementation, there will be only one Validator NextValidators *types.ValidatorSet Validators *types.ValidatorSet LastValidators *types.ValidatorSet LastHeightValidatorsChanged int64 // Consensus parameters used for validating blocks. // Changes returned by EndBlock and updated after Commit. ConsensusParams tmproto.ConsensusParams LastHeightConsensusParamsChanged int64 // Merkle root of the results from executing prev block LastResultsHash [32]byte // the latest AppHash we've received from calling abci.Commit() AppHash [32]byte }
State contains information about current state of the blockchain.
func NewFromGenesisDoc ¶
func NewFromGenesisDoc(genDoc *types.GenesisDoc) (State, error)
NewFromGenesisDoc reads blockchain State from genesis.
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.
