Estonia Started Voting From the Couch in 2005

In October 2005, 9,317 Estonians cast votes for their local councils without going anywhere. They opened a laptop, slotted in a national ID card, entered a PIN, and clicked. It was the first legally binding political election anywhere that let the entire electorate vote over the open internet.

The trick was the card, not the website. Estonia had issued every adult a mandatory chip-bearing ID since 2002. The chip held two private keys — one for authentication, one for digital signatures — backed by a state-run public key infrastructure. To vote, you needed the card, the reader, and two PINs. The vote was encrypted to the election commission's public key, signed with your card, and sent. To handle coercion, the system let you re-vote as many times as you wanted up to the deadline; only the last ballot counted, and a paper ballot at the polling station overrode all of them.

In 2007 Estonia became the first country to run a general election with internet voting available — 30,275 ballots, about 3.4 percent. Adoption climbed from there. By the 2023 parliamentary election, 312,181 votes were cast online: 51.1 percent of all votes, a majority for the first time.

The system has critics. A 2014 international research team that observed the 2013 elections concluded the architecture was vulnerable enough that it shouldn't be used. The OSCE has flagged verification gaps in every cycle since. After the 2023 election a domestic poll found about 40 percent of Estonians distrusted the system, and parliament opened hearings on independent auditing.

The i-vote works because the rest of the digital state works. You file taxes on the same card, sign mortgages on it, get prescriptions on it. By the time the ballot lands on the screen, the trust question has already been answered for you a hundred other ways.
