is an experiment in using the blockchain to provide a secure unmoderated decentralized message board.
Message posts are permanent. There's no server-side logic, all transactions and calls are to/from the Ethereum blockchain directly, meaning that anybody can deploy their own wall or create their own viewer app to interact with the message board.
The frontend supports markdown syntax and code block highlighting. You can also sponsor posts with Ether to highlight your messages (or to claim the sticky "Top Sponsor" slot at the top!) There's some functionality in the contracts that I haven't built into the front-end yet (an open directory for multiple public boards, the ability to gift ether to posters when you "like" messages) so I'll evolve the front-end over time.
Suggestions and feedback welcomed
