Estonia - GovChain
Estonia may perhaps be the earliest adopter of distributed ledger technology at a governmental level. As early as 2007, even before the publication of the Bitcoin white paper, the Estonian government was already testing blockchain applications as part of a resolution to be resilient to outsider cyberattacks. e-Estonia, a government policy to facilitate citizen interactions with the state through the use of electronic solutions, has been testing and implementing blockchain in relation to public services for many years.
