**Abstract**

Blockchain technology is a public ledger that stores data in a chain of blocks which can radically improve the quality of our records from "records that might be trustworthy" to "records that trust is absolute". This chapter explores one area that blockchain technology can radically transform but has not yet received significant attention. We evaluate the suitability of applying blockchain technology for corporate social responsibility (CSR) reporting. We demonstrate that blockchain technology is suitable in the context of CSR reporting since there is a strong need for an immutable common database shared among various stakeholders with potential trust issues. We also argue that blockchain technology does not completely eliminate existing trusted third parties such as governments, international organizations that provide CSR reporting standards, major CSR reporting assurance companies and major CSR infomediaries. In particular, blockchain technology can be used as a platform that integrates all traditional trusted third parties, transforms their functions, and reduces their drawbacks for advancing CSR reporting. We also demonstrate that a permissionless public blockchain would be the most suitable structure.
