In this chain, the work of every miner need to do is acting as an "search engine spider", aka PoF(Proof of Fetch), the miner will . While running the mining software, everyone will gather webpage's url & info from a source url which can be desided by miner, and then push these to the blockchain. To get rid of scam on pushing, the blockchain system will check every page and each url & detail. The rule of verification is that the url & page will be sent to each MN, and if passing more than 10 other nodes' check on 10 block, the miner will get rewards. So with consistently pushing sites and detail to the chain, they would gain considerable benefit from chain.
