Functions

func BlockNumberByTransactionHash

func BlockNumberByTransactionHash(ctx context.Context, c *rpc.Client, txHash common.Hash) (*string, *types.Transaction, error)

BlockNumberByTransactionHash gets a block number by a transaction hash in that block

func Client

func Client(url string) *ethclient.Client

Client gets client or fails if no connection

func ClientRPC

func ClientRPC(url string) *rpc.Client

ClientRPC RPC Client gets an RPC client (useful to get the block number out of a transaction)

func ConvertAndAppend

func ConvertAndAppend(c *ishell.Context, input string, argument *abi.Argument, output []interface{}) ([]interface{}, error)

func ConvertToBool

func ConvertToBool(value string) (bool, error)

MUST CHECK RETURNED ERROR ELSE WILL RETURN FALSE FOR ANY ERRONEOUS INPUT

func ConvertToInt

func ConvertToInt(signed bool, size int, value string) (interface{}, error)

func ConvertToType

func ConvertToType(str string, typ *abi.Type) (interface{}, error)

func EncodeBlock

func EncodeBlock(blockInterface interface{}) (h []byte)

Encodes a block

func EncodeExtraData

func EncodeExtraData(blockHeader Header) (prefix []byte)

EncodeExtraData calculate prefix of the extraData with the signature

func EncodePrefix

func EncodePrefix(blockHeader Header) (prefix []byte)

EncodePrefix calculate prefix of the entire signed block

func GenerateInterface

func GenerateInterface(blockHeader Header) (rest interface{})

GenerateInterface Creates an interface for a block

func GenerateProof

func GenerateProof(ctx context.Context, client *rpc.Client, txHash common.Hash) ([]byte, error)

func GetBlockTxReceipts

func GetBlockTxReceipts(ec *ethclient.Client, block *types.Block) []*types.Receipt

GetBlockTxReceipts get the receipts for all the transactions in a block

func GetNonce

func GetNonce(client *ethclient.Client, auth *bind.TransactOpts)

func Proof

func Proof(trie *trie.Trie, path []byte) []byte

Proof creates an array of the proof pathj ordered

func ReceiptTrie

func ReceiptTrie(receipts []*types.Receipt) *trie.Trie

ReceiptTrie generate trie for receipts TODO: the argument should be of type interface so that this is a generic function

func StringToBytes32

func StringToBytes32(input string) (output [32]byte, err error)

Needed to convert transaction strings into the correct format

func TxTrie

func TxTrie(transactions []*types.Transaction) *trie.Trie

TxTrie generated Trie out of transaction array TODO: the argument should be of type interface so that this is a generic function
