Hyperledger Fabric is a permissioned blockchain infrastructure, originally contributed by IBM and Digital Asset, providing a modular architecture with a delineation of roles between the nodes in the infrastructure, execution of Smart Contracts (called "chaincode" in Fabric) and configurable consensus and membership services.
Private blockchains (or permissioned blockchains) are different from public blockchains, which are available to any node that wishes to download the network. Critics of public blockchains say because everyone can download a blockchain and access the history of transactions, there is not much privacy. [ 9 ]
Blockchain security methods include the use of public-key cryptography. [40]: 5 A public key (a long, random-looking string of numbers) is an address on the blockchain. Value tokens sent across the network are recorded as belonging to that address.
Certificate Transparency is an Internet security standard for monitoring and auditing the issuance of digital certificates based on a distributed ledger. It was initiated in 2011, standardised in 2013 and started to be used by the Google Chrome browser for all certificates in 2018.
Source-route transparent bridging, abbreviated SRT bridging, is a hybrid of source routing and transparent bridging, standardized in Section 9 of the IEEE 802.2 standard. It allows source routing and transparent bridging to coexist on the same bridged network by using source routing with hosts that support it and transparent bridging otherwise.
The tokenization system must be secured and validated using security best practices [6] applicable to sensitive data protection, secure storage, audit, authentication and authorization. The tokenization system provides data processing applications with the authority and interfaces to request tokens, or detokenize back to sensitive data.
