It can be said that the election was electronic, however other countries have used electronic polling stations (notably the USA) and those have since been proven to be easily hacked and the results modified. The headline here stating the use of blockchain is important because its the first election on the planet that has used the implementation and its an implementation that can't be modified without trace. As for point two I have no idea, I am assuming it required people using voting booths but given the technology used, nothing is stopping it from allowing decentralized voting. edit: As it turns out it looks as though people voted using traditional paper ballets and it was inputted into the block chain via a neutral third party: https://www.bitguru.co.uk/sierra-leone-presidential-election-powered-by-blockchain-voting/ https://www.bitguru.co.uk/sierra-leone-presidential-election...
