National Elections Using Blockchain

Sierra Leone became the first country to use blockchain tech to record its election results. On March 7, 2018, seventy percent of the country’s polling results were recorded to the blockchain.

The results were stored in an immutable ledger. This provides instant, publicly verifiable, access to election results. The votes themselves were anonymous, so privacy was maintained. Also having the votes stored in an immutable ledger provides security in that the results cannot be modified after reporting. Only the software entering the results at the time of the vote needs locking down, because the results cannot be modified after they are entered.

This is the type of application that Solidity based blockchain apps on the Ethereum blockchain excel at. Transparency of data, publicly verifiable results, and increased user trust in public voting is a great use for the Ethereum blockchain.
