However, I made a PPT to explain how https://docsend.com/view/2n3cjscwf7c2mb29
It requires a personal email; it doesn't accept temporary email addresses apparently. Is it private / academic work? If it isn't sensitive, upload it elsewhere. Since the miners are already paid with the file storage, the blockchain will not need to issue/mint new coins to pay the miners.
There are two ways you can reward a miner; tax the users directly, or tax the users indirectly. 
You have to either mint new coins, or collect some miner tax from users. As far as I understand, miners' income comes from file uploaders.
The storage users pay for the storage, and they need to get the proof that their files are honestly stored.
Oh. So, the difference with a cloud service and a filecoin-like blockchain is that the latter provides proof of the storage?The encoding algorithm output two things within same computation: 1. the encoded content (replication) 2. PoW blockchain consensus (new block)
The file content will have to either be included into a block, or included into miner's local disk. Isn't that correct? Since the former can't scale, how do you ensure the miner will keep it in his personal storage, or just that he'll not go offline right after you pay him?
