Bitcoin, in the sense of the digital currency, is not used at all. However, the Bitcoin protocol and the implementation of the neat idea of block chain is on the basis of twister. The block chain provides a sort of distributed notary service, certifying who owns a given nickname. The name is associated with a specific key pair, which is used for authentication and cryptography.

Can I mine Bitcoins with twister?

Not exactly. The same mechanism used in Bitcoin for mining is also used in twister but for a different purpose, ensuring the order in which user registrations took place (the nickname belongs to whoever registered it first). twister network must incentive users to mine, so block chain may keep advancing. However, unlike Bitcoin, there is no monetary value involved. The twister incentive is: whoever finds the hash collision to validate a new block of transactions will be awarded with the right to send a promoted message. Promoted messages have a certain probability of being displayed by twister client.
