Abstract: Abstract Digital identity is now required for virtually all transactions and is fundamental to individual standing for most activities. The authenticity and accuracy of identity is import to governments, businesses, and individuals. Because of the increased economic and legal significance of digital identity there is interest by governments around the world in using blockchain and other distributed ledger technologies to replace paper-based identity records for identity authentication and verification. A number of governments are considering moving to a blockchain-based system, while others have already moved to this new technology. There are advantages in doing so, but there are implications that have not been adequately analyzed. This chapter examines the advantages and challenges presented by blockchain identity systems and the implications, particularly for governments and individuals relying on blockchain-based identity. The chapter concludes with a framework for new approach to support use of blockchain for identity authentication.
