Functions

func EmptyPool

func EmptyPool(mgr *ChainManager)

empty the tx pool

func GenesisKeys

func GenesisKeys() crypto.Keypair

TODO

func GenesisTx

func GenesisTx() block.Tx

func HandleTx

func HandleTx(mgr *ChainManager, tx block.Tx) string

func MakeBlock

func MakeBlock(mgr *ChainManager)

function to create blocks, called periodically currently assumes we can create blocks at will and we don't sync

func MakeBlockLoop

func MakeBlockLoop(mgr *ChainManager, blocktime time.Duration)

func MakeGenesisBlock

func MakeGenesisBlock() block.Block

func ReadGenBlock

func ReadGenBlock() block.Block

func ReadState

func ReadState()

func ShowAccount

func ShowAccount(mgr *ChainManager, account string)

func TxValid

func TxValid(mgr *ChainManager, tx block.Tx) bool

valid cash transaction instead of needing to evluate bytecode like Bitcoin or Ethereum this is hardcoded cash transaction, no multisig, no timelocks * sufficient balance of sender (the sender has the cash, no credit as of now) * the sender is who he says he is (authorized access to funds) speed of evaluation should be way less than 1 msec TODO check nonce

func WriteGenBlock

func WriteGenBlock(block block.Block)

func WriteState

func WriteState()
