Algorithm 2. BSF-EHR Doctor and Insurance Agent Blockchain Formation and Block Addition
Input	:	Referred patient block from the patient blockchain
Output	:	Doctor Doc1 Blockchain formation and Add blocks to Doctor Doc1 Blockchain and Insurance Agent IS1 Blockchain formation and Add blocks to Insurance Agent IS1 Blockchain
Step 1	:	Block ← Doctor Doc1 and Insurance Agent IS1 can download his referred patient Block from the patient blockchain using the private key.
Step 2	:	Block → Retrieve encryptedEHR, Hash with Bilinear Map from Block
Step 3	:	Decrypt encryptedEHR based on Private Key → EHR
Step 4	:	Doctor Doc1 and Insurance Agent IS1 can access this EHR
Step 5	:	Create Genesis block for Doctor Doc1 blockchain using doctor name, password and doctor ID and Create Genesis block for Insurance Agent IS1 blockchain using insurance agent name, password and insurance agent ID
Step 6	:	Block ← Put encryptedEHR, hash with Bilinear Map
Step 7	:	Add this Block to Doctor Doc1 Blockchain and Insurance Agent IS1 Blockchain
Step 9	:	Insurance Agent IS1 provides the Lump-sum payment for the treatment of covered illness. This amount is transferred to the particular patient block
