Private blockchain is a type of blockchain network that is only accessible by a selected group of participants, offering more scalability, efficiency, and security than public blockchain. However, interoperability and innovation are challenges for private blockchain networks. Substrate Framework is a modular platform that allows developers to build customized blockchains with ease and flexibility. Its support for interoperability through Polkadot Network and innovation through runtime upgradeability feature makes it a powerful tool for private blockchain development. Substrate Framework also supports scalability, performance, security, and governance, and can be used to build identity tokens (IDTs). IDTs are digital tokens that represent one’s identity attributes on the blockchain, enabling users to prove their identity online without revealing sensitive personal information. Substrate Framework provides a customizable platform for building private blockchains and IDTs that are interoperable with other networks or systems through Polkadot Network, enhancing the security and privacy of IDTs.
