The public data may be accessible to any node in the blockchain network, while the private data may be accessible only to nodes specified in an access list, which may be provided when a record is added to the blockchain. When a new record is received, any private fields in the record may be identified and encrypted by a receiving node. The key may then be encrypted and sent with the protected record to other nodes in the access list. These nodes can access the encryption key, decrypt the private fields, and provide a consensus decision to a receiving node. After consensus, the protected record may be added to the blockchain, where the public fields may be freely accessed by any node, and the private fields remain accessible only to nodes in the access list."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Securely sharing selected fields in a blockchain with runtime access determination","description":"A blockchain architecture allows blocks to store both public and private data.
