Why Private Blockchain and How Substrate Framework Can Help

by
Blockchain and digital identity

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.

IoT conference 2022 at Delft

We present in this work a Lightweight Transaction Protocol (LTP) for enabling constrained embedded devices’ interaction with multiple types of blockchains via the LoRaWAN communication protocol. The proposed protocol provides the benefit of interacting with multiple blockchains with only 13.5\% decrease in battery life. The protocol also includes a gateway module API that connects to blockchains and generic smart contracts to authenticate end devices and store their data. The study points out that, in the worst case, end-device data can be stored in blockchains with a latency of 20.3 seconds for Substrate and 6.8 seconds for the Hyperledger Fabric blockchain.
