I wonder if there's a large enough market for a "decentralized cloud" along the lines of IPFS but for compute. And, yknow, actually working decently. Something where you could pay compute/storage operators for resources and also be a server host and share your excess compute power.

This is effectively the idea behind the Ethereum blockchain model. You can make "smart contracts" (think APIs with persistent state) using languages like Solidity[1] and deploy them onto the blockchain. After that, you can invoke individual functions by paying "gas" (small amounts of ETH) that goes to the node operator's account. Smart contracts also get their own blockchain addresses, so they're capable of sending and receiving transactions. Meaning you can build financial applications with little to no barriers to entry! (whether this is a good thing or not, I will leave up to the reader). The really cool thing about it is that nobody owns a smart contract once it's deployed. You can't edit the code or even delete the contract itself. It's a truly autonomous entity that will continue to operate the same way forever (unless there's a 51% attack or something of that nature). The obvious benefit for this is that you can mathematically ensure trust. For example, if you hosted a lottery app on a LAMP stack, you could steal the money, hackers could get into your server, your database could get corrupted, etc. On the blockchain, nobody can access your lottery funds or business logic, not even yourself, meaning that as long as you developed the application correctly (to be fair, that is a big assumption), it is truly fair.

  I always wondered about this, so how do projects like CryptoKitties profit? Or do they give themselves the seed cryptocollectibles and profit off of those?

    > give themselves the seed cryptocollectibles and profit off of those In CryptoKitties' case specifically, yes. Some developers bake a fee directly into the smart contract.

      So they coded the fee system to go to their own address and not just the systems hosting correct?
