JSMiner

[James Peerless]

Looked over several of the projects that make up "bitcoinjs" but couldn't really find one related to mining? Is there an implementation or a 'stub' for a javascript based mining of bitcoins?

There was never a browser mining component in BitcoinJS. There is mining functionality in bitcoinjs-server, but right now only for unit testing purposes, i.e. to prove that the node can generate valid blocks. (You would then use this to mine using a standard Bitcoin miner like cgminer for the actual proof-of-work.)

With a bit of googling I was able to find a bunch of WebCL JavaScript miners floating around, e.g.

https://github.com/temujin9/tumen_miner

Nothing I found looked particularly polished, but if you do some poking around you should be able to piece something together.

If someone builds a fairly clean WebCL miner I'd be happy to host it at bitcoinjs/bitcoinjs-miner if desired.
