What will be if “bad” node will generate long fake blockchain from genesis and spread it to “good” nodes?
Will blockchain be replaced to fake one in the “good” nodes?
Can we evade this by checking if the longest blockchain prefixed by our current blockchain?

This project gives a basic idea of blockchain implementation and it doesn't implement any consensus algorithms prevent to run this as a public blockchain. As long as the blockchain is longer and valid, it will propagate to all nodes.
