| Indeed, that's seems like a big weak point: you need to understanding the technology to trust it! First, I think that's a great news, if the limitation is only human and not logical, because humain can changes (a bit). Let's look at the digital world currently: Peoples, companies and state, use internet to store and transfer private and valuable informations. All the world financial assets are process on the network, almost everyone use ATM, and store personal picture online etc.
All of this with just a very few percent of the population (people like me and you) knowing "more or less" how this really works! A main adoption of online voting on the block chain will required efforts for everybody with the knowledge to democratize it, but in fact you don't need to understand all of it to trust it (like when you withdrawing money from an ATM). We could say right now that everyone owning bitcoin "trust" the block-chain, and I would be surprise if more than 50% of them have read and understand Satoshi's whitepaper and the fundamental basics of the network. Also at the end, even if it's intellectually new, it's not that difficult to understand even for our beloved parents :) |
