Sites like memo.cash & blockpress host their content on the blockchain, then provide a web accessible version of it through their website/server. I assume they have a node that pulls transactions with the appropriately prefixed OP_RETURN and populates the pages with the posts you see on those sites. I've mainly stuck to SPV wallets to save disk space, but I'm interested in these uses of the blockchain that aren't strictly financial. If I too want to read transactions to pull status updates or other uses of OP_RETURN, is there a simple library that could be integrated into a web server stack for these purposes?
