Video; Bitcoin Quanum Hack
This YouTube video by Ivan is about a Russian solution to the possible problem of quantum computers being able to hack the Bitcoin Blockchain.
The solution is to imbed a block’s data with quantum particles that change their state, if they are viewed or tampered with.
So, if a quantum computer figures out how to fake a transaction, the quantum particles would change and trusted parties on the network would know the data in a block had been changed and could invalidate the block.
