type GraphVerifier

type GraphVerifier struct {

func (*GraphVerifier) Verify

func (v *GraphVerifier) Verify(txi types.Txi) (ok bool)

Verify do the graph validation according to the following rules that are marked as [My job]. Graph standards: A1: [My job] Randomly choose 2 tips. A2: [Not used] Node's parent cannot be its grandparents or ancestors. A3: [My job] Nodes produced by same source must be sequential (tx nonce ++). A4: [------] Double spending once A3 is not followed, whatever there is actual double spending. A5: [Pool's job] If A3 is followed but there is still double spending (tx nonce collision), keep the forked tx with smaller hash A6: [My job] Node cannot reference two un-ordered nodes as its parents B1: [My job] Nodes that are confirmed by at least N (=2) sequencers cannot be referenced. B2: [My job] Two layer hash validation Basically Verify checks whether txs are in their nonce order

type TxFormatVerifier

type TxFormatVerifier struct {
	MaxTxHash         types2.Hash // The difficulty of TxHash
