type Block

type Block struct {
	Num uint64
	Txs []*Transaction
}

Block is used to used to hold the information from its proto format to a structure that is more suitable/friendly for validation

type Transaction

type Transaction struct {
	IndexInBlock   int
	ID             string
	RWSet          *rwsetutil.TxRwSet
