 So this is a proof of dance dance, this is a dance dance revolution that mines cryptocurrency on private Ethereum blockchain and this was made by myself, Agnes Cameron and Kali Redzepi and the Vile Communications Group here at the lab. We originally made this for a party, kind of as a joke, but since then we've decided that it's real home should be as a true cryptocurrency and so here we are. So Kali here is dancing and every time she scores a point the hash rate of the miner increases and a block gets mined. Collectively this morning we've mined about 129 blocks on the blockchain. The last party we tried this at we got about 10,000 and really that's really a collective effort of hundreds of different dancers. We can see this becoming a real cryptocurrency, I think that the most feasible way of implementing this really would be in a peer-to-peer network of dance mats and so as the number of people dancing goes up so does the market capitalization of the currency and really this is just looking at a kind of different and maybe more scalable consensus mechanism than the current proof of work which has obvious like bad environmental implications. We've been talking a lot in the group about kind of possible futures that this project could have. I think as well like one of the ideas that has been passed around is potentially you know when robots have automated all the jobs what are we going to do all day how will we create value and well maybe it's through dancing.
