Socket.io is GREAT, and I love that you guys are using it instead of jQuery ajax, especially because Socket.IO allows you to make a bit a P2P.
So let’s not stop here. It would be really, really nice to use Socket.IO to decentralise the transaction process, it would save you a bit of money and give more sense to the mining process. Bitcoin mining is justified by the decentralisation, you keep the network alive so you’re rewarded with coins.
JSECoin mining doesn’t really make sense (from a technical point of view) for now, so… GO FOR IT. 😉
