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.
For this, you first need to make an identification system with decentralized architecture with the blockchain.
And only then to each identifier issue a wallet with 1 coin.
Or use one of the currently being developed - Civic or Humaniq.
