Blockchain Platforms Overview for Industrial IoT Purposes

There are a lot of blockchain platform implementations available today. To be integrated into the smart space for Industrial IoT the blockchain platform should support not only token exchange but also smart contract distribution and launching, fault tolerance consensus mechanism and equivalence between participants to create and implement new blocks and contracts. The paper provides analysis of the most used consensus mechanisms, specific features of public (permissionless) and private (permissioned) blockchains. Also a description of blockchain platforms that satisfy the requirements for the IIoT platform development is provided. By the result of the analysis the platform and specific modules have been selected for implementation of blockchain for industrial IIoT platform.
