Algorithm A1: Collect cross-chain smart contract A(CCSC-A)

Input: H(user); D; Dn; DATA; Ds; T; AD; CCSC-B; pkp; Y; F; 1: func Certification($H$(user)) (D) // Data acquisition module {  For t in range ($m$) If $H$(user) permissions match   Matching collection information:{Hazardous Material Information or corporate information or consumer information or regulatory agency information or transaction records or cost information or data interaction records or health records or other information} If Data validation after data standardization  Return Step 2 } 2: func Hash lock($D$)// Data encryption module { For t in range (m) If D standards compliant   Get data summaries Ds D$\to$N$\to$H(N)// D takes a random number N and generates the corresponding hash value H(N) Dn$\leftarrow$Encrypt H(N)(D)// Encrypt D using H(N) to generate ciphertext Dn DATA$\leftarrow$Encryptpkp(Dn, H(N), Ds)// Use the user’s public key to integrate and encrypt Dn, H(N), and Ds to generate data packets DATA If Ds, H (N), Dn, DATA generate  Return true Return false } 3:func Slice(DATA)// Data Fragmentation Module{  For t in range (m) If Step 2 returns true Slice(DATA)//DATA Fragmentation Send(DATA)$\to$Relay chain (node)// Data shards are stored in each node of the relay chain Return true      Return false } 4:func Game(Relay chain (node))// Game module { For t in range (m) If Step 3 returns true Game(node)// The game of each node of the relay chain obtains the right of reorganization Return Relay chain (node)$\leftarrow$DATA// Data normalization      Each node encrypts data shards and returns H(DATA) to the contract      If Judgment complete: Set(T)// Set time lock T Verify(H(DATA)>51%)// The amount of H (DATA) returned within T time is greater than 50% Return true Return exit } 5: func Get(AD)// storage module { If Step 4 returns true Transfer(CCSC-B) Return CCSC-A$\to$N; AD$\to$CCSC-A// N and AD exchange to obtain Store AD to the blockchain If   Store successfully verified: Verify(Decrypt (D)) $\to$Y/F// Verification of CCSC-B decryption result notification Y/F Return Storage(AD) and true Return Exit and false //main chain, exit is interrupt cross-chain transmission in time }
