Not just the design but the actual implementation. Maybe not worth adding here but something that immediately popped into my head when I read that sentance.

Maybe: "Bitcoin, and blockchain technology in general."? Bitcoin is a blockchain technology, so it seem redundant unless you're asking the reader to know Bitcoin specifically and also blockchain technology in general.

In the age of demonitization, this might be a good place to mention that LBRY prevents demonitization. "trust" can mean that I guess, but it's not obvious.

confusing statement

Blockchain provides for consistent metadata but I'm not sure how "across the network" makes sense here (it's defining more of what a blockchain is rather than something special we've done with it), I would just drop that part. Maybe: "LBRY uses a blockchain to record metadata about digital content, make it discoverable and support buying and selling." or some variation of that?

I assume that 'accessing' here implies purchasing but does it really? ¯_(ツ)_/¯

I thought LBRY was a Network or at least a suite of protocols, not a single protocol.
