The problem Blockchain & Cryptocurrency - blinkscoin solves

We created a cryptocurrency called blinkscoin, add transactions to our blocks and allow other nodes to connect to our network. Each node is running an instance of our blockchain, we also synchronized our blockchain across all the nodes connected to our network.
we used hash-operations to represents the cryptographic puzzle required for mining blocks. The three request methods, mine_block , get_chain & is_valid are invoked whenever a GET request is sent to specific URL endpoints that are hooked with our methods.
