Talking about transmitting of elections using Blockchain, Currently there is a ban on crypto transaction in Nigeria and I think Nigeria will be the very last country to adopt such transparent system due to their level of curruption and slowness in the adoption of new evolving technology.
Everybody who wants Internet and World Wide Web freedom needs to consider NOSTR. The only way to block NOSTR is to shut down the Internet. It could be used to implement a corruption-proof voting operation.
What is NOSTR? It's a super-basic form of social media. And all kinds of applications can be built on it. This means that cryptocurrencies can bypass government censors. The only way government can stop NOSTR is to shut down the Internet.
NOSTR is in its beginning stages. Not many platforms are built on it, yet. Those of you who are developers should start now.
