Keyed Content and Conditional Key Release
There was no honest way to sell access to a piece of content on chain. Existing paid-post systems just hid restricted text behind a rendering convention while leaving the real content sitting in plaintext on the blockchain for anyone to read for free. This makes it possible to actually encrypt content once, publish it anywhere, and hand out the key only to people who pay or otherwise qualify, so the restriction is real and the buyer keeps access forever.
