Information and communication technologies are used by e-Government to deliver governmental services to people
and companies instantly, effectively, and efficiently. The majority of current e-government systems are centrally located on
redundant servers and databases that may have single points of failure, rendering the systems susceptible to cyber-attacks.
Blockchain technology makes it possible to build a decentralised, incredibly secure system without the need for a central
authority to monitor transactions. Blockchain technology, which encrypts data and distributes it over the network, improves
information security and privacy and gives governments new chances to increase transparency, stop fraud, and foster citizen
confidence. In this paper, we primarily cover the overview of blockchain technology, architecture of blockchain, consensus
models and the blockchain use cases in e-Government.
