I was having a kind of thought experiment...
Let's say that you create a new crypto-currency. Before the creation of the first genesis block you create 25 billion wallets with each 1 coin in it. The purpose of this would be that anyone on earth, could claim his 1 coin at anytime.
My question:
How would you prevent that someone claims more than 1 wallet?
PS: I didn't incorporate more details because this is not necessary for the question at hand.
That would be a very hard thing to regulate. But i think it helps if you implement stricter user profile verification processes in to your wallet to ensure no duplication. I'm thinking of adding additional safety and unlock features like finger print verification or iris verification. Since most mobile phones have finger print scanners so that would do for a start.
