Automotive Supply chain . HLF is a private, permission-based blockchain network that allows secure identity management using PKI. The 'key' is the essence of the existence of digital assets. An asset can be tangible (a house, car, cash, land) or intangible (intellectual property, patents, copyrights, branding).Virtually anything of value can be tracked and traded on a blockchain network, reducing risk and cutting costs for . In these cases, the key to supply chain management involves establishing provenance of items being traded, and blockchain can ensure a transparent, secure, un-editable and un-deletable provenance which could help all parties in the supply chain. This inevitably increases the risk of theft and misuse of private keys. NIST compliant encryption and key management, a key vault, and key access control are built into each registered blockchain node. Since the permissioned blockchain incorporates the identities of blockchain nodes, the need for HSMs is critical. Blockchain spending is forecasted to hit $11.7 billion in 2022.
