This chapter examines the public sector applications of blockchain technology in government. Blockchain has found quick adoption in the public sector with versatile uses across several domains. We survey these extant and potential uses of blockchain in this chapter. Governments mediate or undertake a plethora of transactions which require transparency, security, and integrity in the long term. Blockchain technology has a strong potential to fulfill these requirements for governmental operations. We highlight the technology’s application in transforming various such government functions. Exemplary governmental uses of blockchain include those related to real estate, digital identity, infrastructure management, safety, and emergency management, and smart contracts. These cases demonstrate how the blockchain technology’s applications transcend those of the traditional use in cryptocurrency. We posit that the blockchain technology can potentially enhance efficiencies in the delivery of public services securely across several domains, but the realization of these uses requires more institutional learning and acceptance of the technology.
