Types

type Address

type Address string

func NewAddressFromBytes

func NewAddressFromBytes(data []byte) (Address, error)

func (Address) Decimal

func (a Address) Decimal() (decimal.Decimal, error)

func (Address) Decode

func (a Address) Decode() (string, []byte, error)

Decode decodes address, returning the human-readable part and the data part excluding the checksum.

func (Address) String

func (a Address) String() string

type Block

type Block struct {
	Header `json:"header"`
	Data   `json:"data"`
	// Evidence   types.EvidenceData `json:"evidence"`
	LastCommit *Commit `json:"last_commit"`
}

Block defines the atomic unit of a CometBFT blockchain.

type BlockData

type BlockData struct {
	ResultBlock
	ResultBlockResults
}

type BlockId

type BlockId struct {
	Hash Hex `json:"hash"`
}

type BlockParams

type BlockParams struct {
	// Note: must be greater than 0
	MaxBytes int64 `json:"max_bytes,omitempty,string" protobuf:"varint,1,opt,name=max_bytes,json=maxBytes,proto3"`
	// Note: must be greater or equal to -1
	MaxGas int64 `json:"max_gas,omitempty,string" protobuf:"varint,2,opt,name=max_gas,json=maxGas,proto3"`
}

BlockParams contains limits on the block size.

type Commit

type Commit struct {
	Height     int64             `json:"height,string"`
	Round      int32             `json:"round"`
	BlockID    BlockId           `json:"block_id"`
	Signatures []types.CommitSig `json:"signatures"`
}

type Consensus

type Consensus struct {
	Block uint64 `json:"block,omitempty,string" protobuf:"varint,1,opt,name=block,proto3"`
	App   uint64 `json:"app,omitempty,string"   protobuf:"varint,2,opt,name=app,proto3"`
}

Consensus captures the consensus rules for processing a block in the blockchain, including all blockchain data structures and the rules of the application's state transition machine.

type ConsensusParams

type ConsensusParams struct {
	Block     *BlockParams     `json:"block"     protobuf:"bytes,1,opt,name=block,proto3"`
	Evidence  *EvidenceParams  `json:"evidence"  protobuf:"bytes,2,opt,name=evidence,proto3"`

}

ConsensusParams contains all consensus-relevant parameters that can be adjusted by the abci app

type Data

type Data struct {
	// Txs that will be applied by state @ block.Height+1.
	// NOTE: not all txs here are valid.  We're just agreeing on the order first.
	// This means that block.AppHash does not include these txs.
	Txs types.Txs `json:"txs"`

	// SquareSize is the size of the square after splitting all the block data
	// into shares. The erasure data is discarded after generation, and keeping this
	// value avoids unnecessarily regenerating all the shares when returning
	// proofs that some element was included in the block
	SquareSize uint64 `json:"square_size,string"`
}

Data contains all the available Data of the block. Data with reserved namespaces (Txs, IntermediateStateRoots, Evidence) and Celestia application-specific Blobs.

}

Event allows application developers to attach additional information to ResponseBeginBlock, ResponseEndBlock, ResponseCheckTx and ResponseDeliverTx. Later transactions may be queried using these events.

}

EventAttribute is a single key-value pair, associated with an event.

type EvidenceParams

type EvidenceParams struct {
	// Max age of evidence, in blocks.
	//
	// The basic formula for calculating this is: MaxAgeDuration / {average block
	// time}.
	MaxAgeNumBlocks int64 `json:"max_age_num_blocks,omitempty,string" protobuf:"varint,1,opt,name=max_age_num_blocks,json=maxAgeNumBlocks,proto3"`
	// Max age of evidence, in time.
	//
	// It should correspond with an app's "unbonding period" or other similar
	// mechanism for handling [Nothing-At-Stake
	// attacks](https://github.com/ethereum/wiki/wiki/Proof-of-Stake-FAQ#what-is-the-nothing-at-stake-problem-and-how-can-it-be-fixed).
	MaxAgeDuration time.Duration `json:"max_age_duration,string" protobuf:"bytes,2,opt,name=max_age_duration,json=maxAgeDuration,proto3,stdduration"`
	// This sets the maximum size of total evidence in bytes that can be committed in a single block.
	// And should fall comfortably under the max block bytes.
	// Default is 1048576 or 1MB
	MaxBytes int64 `json:"max_bytes,omitempty,string" protobuf:"varint,3,opt,name=max_bytes,json=maxBytes,proto3"`
}

EvidenceParams determine how we handle evidence of malfeasance.

	ValidatorsHash     Hex `json:"validators_hash"`      // validators for the current block
	NextValidatorsHash Hex `json:"next_validators_hash"` // validators for the next block
	ConsensusHash      Hex `json:"consensus_hash"`       // consensus params for current block
	AppHash            Hex `json:"app_hash"`             // state after txs from the previous block
	// root hash of all results from the txs from the previous block
	// see `deterministicResponseDeliverTx` to understand which parts of a tx are hashed into here
	LastResultsHash Hex `json:"last_results_hash"`

	// consensus info
	EvidenceHash    Hex `json:"evidence_hash"`    // evidence included in the block
