| I believe it does. Let's take it point by point. Shared data store: yes. One of the biggest problems with Bittorrent is that you can only use it if you already know the infohash of the content you want. There's no index of the available content. There are lots of third-party search engines that try to monitor the network and help you find stuff. They are all incomplete and using them is a bad experience. Does more than one entity need to contribute: yes. Anyone and everyone can publish to LBRY or pay for LBRY content. If only one entity had write access, that would be a point of censorship. Data is never deleted: yes. Once you publish something to a decentralized network, its out there. You can't put the toothpaste back in the tube. We actually do have a mechanism to "update" the metadata (description of the content that's stored in the blockchain) by connecting a diff with updated data to the original blockchain transaction. Sensitive information will not be written: yes. No single trusted entity: yes. That's how we can make a strong promises about censorship resistance and you don't have to trust that we won't change our mind later. Tamperproof log of all writes: I'm not sure why this one is strictly necessary, and why we should not use a blockchain if we don't care about a tamperproof log. Please help me understand. |
Even if you can roll back the requirement to "tamper-resistant" you can get away from the necessity of blockchain: use a hash chain instead.
Since you don't care about tampering, I request that you avoid blockchain.
