Designing and implementing a secure public bulletin board is a challenge, that is of significant importance in modern electronic voting protocols. Most often, it is set up as a central server, thus making it vulnerable as single point of failure. On the other hand, the Bitcoin cryptocurrency successfully establishes a decentralized public ledger of transactions, based on block-chain network. The idea of this task is to use the Bitcoin network, or a network built using similar tools/principles, to implement a decentralized bulletin board for electronic cryptographic voting. The result should be a prototype of a network or a Bitcoin network extension, a simplified version of a e-voting system adapted for such a network, and a voting client.
