chainquery

You could look at LBRY (https://lbry.tech https://lbry.com https://beta.lbry.tv). LBRY is similar to PeerTube in open and decentralization, but all content metadata is written to a blockchain, which means everyone/anyone can access the index. This blockchain can then be searched (https://github.com/lbryio/lighthouse) or extracted to SQL (https://github.com/lbryio/chainquery).

They went through a search server we own that runs chainquery. https://github.com/lbryio/chainquery It parses the blockchain and syncs it with a SQL db. Anyone can run their own search server and adjust it as they see fit.

>Okay, so for a use case like The Pirate Bay, which is a popular database of magnet links and related metadata (Description, who added to the database, when added, etc). Users search this data in various ways. The problem with this search index is that it requires all of the .torrent files containing the metadata. In lbry this metadata (as well as more rich fields) are stored to the blockchain, so any full blockchain node has the information to provide more sophisticated searches. Chainquery is what runs a full node and provides the search engine for the UI (https://github.com/lbryio/chainquery). >As in, how would a user search it or find popular torrents? As indicated above, if they're using the UI it provides a search engine via chainquery. Torrents are also not a currently supported source type for a download, however there is nothing

Hey, thanks for the comments! We don't think it's a matter of verification / financial incentives for the blockchain use case, but instead, it's the censorship-resistant, permissionless, and spam prevention factors that count. If we had a centralized database, we could potentially limit access or overwrite records. As far as discovery goes, we've developed a product that helps with exactly this problem - it's called Chainquery. It digests all the metadata from the blockchain into SQL tables that can be easily queried. Check it out at https://github.com/lbryio/chainquery/

Discovery is definitely hard. We've created https://github.com/lbryio/chainquery which parses the blockchain and pumps it into a SQL db for better searching. So that part is still centralized, but anyone who creates an app on LBRY can use this and create their own discovery/search flows. Also see u/CountPrimes answer.
