About bitscribble

This is an experimental research project.

The main object of this website is to provide a simple interface for users to post messages on the Bitcoin blockchain, while also allowing visibility into other's messages recorded via the OP_RETURN script. Call it micro blogging on the blockchain, or waste of Bitcoin's space, no one cares.

Road map and features coming soon:

Add SegWit support
Improved search
Go open-source
Implement Lightning Network Payments

Too keep things interesting, OP_RETURN values that are repeated in a row more than 20 times, or non hexadecimal encrypted text, are sometimes filtered out when scrapping the blocks. Too much illegible messages. Go to coinsecrets.org if you want to read those.
