Overview ¶
Package ledger provides interface to LedgerContract native contract. It allows to access ledger contents like transactions and blocks.
Index ¶
Constants ¶
const Hash = "\xbe\xf2\x04\x31\x40\x36\x2a\x77\xc1\x50\x99\xc7\xe6\x4c\x12\xf7\x00\xb6\x65\xda"
Hash represents Ledger contract hash.
Variables ¶

Functions ¶
func CurrentHash ¶
CurrentHash represents `currentHash` method of Ledger native contract.
func CurrentIndex ¶
func CurrentIndex() int
CurrentIndex represents `currentIndex` method of Ledger native contract.
func GetTransactionHeight ¶
GetTransactionHeight represents `getTransactionHeight` method of Ledger native contract.
Types ¶
type Block ¶
type Block struct { // Hash represents the hash (256 bit BE value in a 32 byte slice) of the // given block. Hash interop.Hash256 // Version of the block. Version int // PrevHash represents the hash (256 bit BE value in a 32 byte slice) of the // previous block. PrevHash interop.Hash256 // MerkleRoot represents the root hash (256 bit BE value in a 32 byte slice) // of a transaction list. MerkleRoot interop.Hash256 // Timestamp represents millisecond-precision block timestamp. Timestamp int // Nonce represents block nonce. Nonce int // Index represents the height of the block. Index int // NextConsensus represents contract address of the next miner (160 bit BE // value in a 20 byte slice). NextConsensus interop.Hash160 // TransactionsLength represents the length of block's transactions array. TransactionsLength int }
Block represents a NEO block, it's a data structure that you can get block-related data from. It's similar to the Block class in the Neo .net framework. To use it you need to get it via GetBlock function call.
type Transaction ¶
type Transaction struct { // Hash represents the hash (256 bit BE value in a 32 byte slice) of the // given transaction (which also is its ID). Hash interop.Hash256 // Version represents the transaction version. Version int // Nonce is a random number to avoid hash collision. Nonce int // Sender represents the sender (160 bit BE value in a 20 byte slice) of the // given Transaction. Sender interop.Hash160 // SysFee represents fee to be burned. SysFee int // NetFee represents fee to be distributed to consensus nodes. NetFee int // ValidUntilBlock is the maximum blockchain height exceeding which // transaction should fail verification. ValidUntilBlock int // Script represents code to run in NeoVM for this transaction. Script []byte }
Transaction represents a NEO transaction. It's similar to Transaction class in Neo .net framework.
func GetTransaction ¶
func GetTransaction(hash interop.Hash256) *Transaction
GetTransaction represents `getTransaction` method of Ledger native contract.
func GetTransactionFromBlock ¶
func GetTransactionFromBlock(indexOrHash interface{}, txIndex int) *Transaction
GetTransactionFromBlock represents `getTransactionFromBlock` method of Ledger native contract.
