Retailers benefit from blockchain technology in four ways: lower costs, faster payments, increased transparency, and improved security.Costs are reduced due to the decentralised nature of transaction automation and application interoperability, which results in the elimination of administration. Faster payments are possible because blockchains do not require centralised infrastructure.No system is immune to external breaches of its security protocols; however, the distributed nature of blockchain provides a level of trust that has never been seen before. Transparency is provided by blockchain's immutability and public availability.Retail Blockchain applications are being developed to address a wide range of retail issues.
