Bram Cohen, inventor of the world-disrupting Bittorrent peer-to-peer filesharing protocol, is now working on a new cryptocurrency.

He discusses it on an episode of the podcast Steal This Show, and you can hear him talk about the future of Bitcoin, the status of cryptocurrencies in general, and his own plans, from 57:30 onward:

The main concept Cohen appears to focus on is the notion of a "storage-based" currency validation model as opposed to a Proof-of-Work model like BitCoin's, which consumes a great deal of energy on the mining side in order to generate hashes and maintain the blockchain. This storage-based model could be called a "Proof-of-Capacity" model, which would both require less energy, and also reduce centralization (and hence potential 51% attacks on the network) in miners, since there would be a wider distribution of storage capacity than currently occurs with the specialized mining tools currently relied on for the BitCoin network.

There is coverage of Cohen's ideas at CoinTelegraph:

And at FossBytes:

Plus TorrentFreak:

What's more, Cohen's speech at Stanford's Blockchain Protocol Analysis and Security Engineering 2017 Conference is available at this page:

which contains both a link to a PDF of Cohen's talk ( ) and a link to a YouTube video of Cohen's talk (video ID aYG0NxoG7yw) -- or watch it below, starting at 1:00 minute, when audio turns on:

Those who start following Bram Cohen's progress now, and potentially hop onto the next big Cryptocurrency at its inception, could benefit greatly!

As the article states in the first line, this alt coin is being developed by Bram Cohen the creator of bittorrent and relies upon a proof of storage, rather than proof of work model in an effort to promote greater decentralization.

I'm not certain if this will result in those who own banks of harddrive software centralizing, rather than those who own banks of asic miners uniting to centralize the coin paradigm.

Feel like it is an innovative and unique approach that could be interesting to keep track of.
