This childhood game could be the blockchain killer app

This is the case of blockchain we did not know we wanted (and we probably do not need it). Now we can play the fabulous game of our childhood playground, Rock, Paper, Scissors on blockchain.

The Reddit user, ikirch, has released a version of the popular game – only this time requires a wallet, some of Ether and Metamask (an dApp interface tool) to play.

But for kids, it's probably easier to keep playing the old way for now. This is strictly for those with a little bit of Ether to throw away (because that's what you'll probably end up doing).

You can play in existing games or start a new one. Other users of the dApp can then play against you or choose another live game to take part in.

[19659002] In principle, it is a good demonstration of blockchain technology. Each player in a game makes his move, and these are seriously stored on the blockchain, to be revealed at about the same time. The immutability of records can confirm the true winner and make sure that the moves are not revealed before the other player has taken his turn.

Playing is perhaps the wrong word. Betting is more appropriate, because when you create a game, choose Rock, Paper or Scissors and put the amount of Ether you are willing to pay to the opponent if they win.

It is not the first time that blockchain has been used in the same phrase of betting.

There are numerous claims that technology will help make sports betting and gambling more transparent. There is certainly an opportunity when it comes to using blockchain for its security, immutability and transparency. But so far they are only statements.

Right now, this Rock, Paper, Scissors game is mostly just a little fun, supported by a solid use of blockchain. It may not change the world, but it shows how the blockchain can work.
