 1 | ## Demo: Aggregation and verification of signatures
 2 | 
 3 | ### codebase：https://github.com/herumi/bls-eth-go-binary
 4 | 
 5 | ### HOW TO START
 6 | 
 7 | #### First: You need to create a new go project. And make sure you init the mod
 8 |     go mod init xxx
 9 | 
10 | #### Second: 
11 |     go get github.com/herumi/bls-eth-go-binary/
12 | 
13 | #### Run:
14 |     go run sample.go
15 |

 8 | 
 9 | var msg string
10 | var msgbyte []byte
11 | var pubs = make(bls.PublicKeys,5)
12 | var signs = make([]bls.Sign,5)
13 | var aggSignbysec bls.Sign

19 | 		sec.SetByCSPRNG()
20 | 		msgbyte = []byte(msg)
21 | 		pubs[i] = *sec.GetPublicKey()
22 | 		signs[i] = *sec.SignByte(msgbyte)
23 | 		fmt.Printf("public key !!!!!!!!!!!!!!!!!!!!!!\n")
24 | 		fmt.Printf("%d,%s\n", i, pubs[i].SerializeToHexStr())

31 | 
32 | //Put the five signatures together
33 | func AggregateSign() {
34 | 	aggSignbysec.Aggregate(signs)
35 | 
36 |
