Algorithm A3: Supervise cross-chain smart contract A(SCSC-A)

Input H(S); Ds; S; SCSC-B; V; IR;DATA 1: func Certification(H(S))// Verify Permissions { For t in range (m) If $H\left(S\right) permissions comply with$  Return Accept cross-chain requests      Return false } 2: func Pretreatment(D)// Cross-chain request preprocessing { If  Data request preprocessing:    Request preprocessing based on concurrency mechanism based on K-means algorithm and Bloom filter   Return The location of the parachain where the requested data resides } 3: func Integration(Data)// Form a supervised cross-chain data Data { For t in range (m)      If Cross-chain supervision data processing:       Extract each parachain data to form Data       Generate a random number N, take the hash H(N), use H(N) to encrypt the Data, and get Dn       Get user pkp, encrypt H(N), Dn, get DATA       Return true Return false } 4: func Slice(DATA)// DATA slices are stored in the relay chain { For t in range (m)    If   Relay chain data processing:        Set the hash lock T        Data slices are stored to relay chain nodes        Each node of the relay chain plays a game, sorts the DATA, and transmits it to SCSC-B        If T ends         Return The DATA fragments of each node in the relay chain are automatically encrypted, and H(D) is sent to SCSC-A         If H(D)>=51%         Return true        Return false      Return false } 5: func Storage(IR)// Interactive record storage {   If  IR deal with:    IR: {Initiate the request related person information, request information, data transmission process information} Stored in the blockchain main chain    Return ture  else    Return false }
