Think about how this would allow the CHinese to access a decentralized web. I also was thinking China might ban ASICS one day (low prob but still) but they couldnt get rid of gpus. Also, IPFS had a horrible ICO.
WHat about other nodes like proof of MIxnet nodes (NYM)? They hae proof of stake for transactions but then proof of mixnet nodes for something the NSA couldnt even track. THis makes it superior to TOR but in countries that have banned VPNs and the like as well as crypto, GPU POW has staying power. STill, china has much of BTCs hash as they just use smaller rigs.
Id love to learn how to do this and build ontop of ERG.
