Algorithm 2

The chaincode about creating the cuckoo filter.

1: Procedure (s SmartContract) InitCFilter(ctx contractapi.TransactionContextInterface) string

2: var cf CFilter

3: configure(&cf)

4: cf.Buckets = make([]bucket, cf.Size, cf.Size)

5: i := range cf.Buckets

6: cf.Buckets[i] = make([]fingerprint, cf.BSize, cf.BSize)

7: cfJSON, _: = json.Marshal(&cf)

8: err := ctx.GetStub().PutState("cuckfilter", cfJSON)

9: If err! = nil then

10:  Return shim.Error(err.Error())

11:   End if

12:   Return string(cfJSON)

13: End procedure
