1. Choose from five blockchains, namely Ethereum, Litecoin, Groestlcoin, Factom or the Bitcoin testnet — when you submit a tweet.
2. You get a Blockchain Receipt with a unique reference number enabling you to look up the corresponding ledger entry at any future date, for many years to come. The format is plain text. Share with family, friends, colleagues.
3. How does it work? What is the "secret sauce"? The magic comes from old-school programming combined together with public blockchains. Each tweet (up to 80 characters) is received, relayed and embedded within the data structures of the various protocols: the Data Payload field in Ethereum, the OP_RETURN fields on the Litecoin, Groestlcoin and Bitcoin testnet networks, and Chain and Entry data structures within Factom. These networks are alternatives to the Bitcoin mainnet. I'm running full nodes in conjunction with custom scripts on the traditional LAMP stack (Linux, Apache, MySQL and PHP). But that may be more information than most people need to know. As the Wizard of Oz said to Dorothy, Scarecrow and the gang, "Pay no attention to the man behind the curtain."
4. This project is an ongoing exploration of protocols, architecture and capabilities. Blockchain enthusiasts, in particular those seeking to leverage data embedding on public chains, please do get in touch, and I promise to respond. Special thanks to Gideon Greenspan for his open-source repositories on Github.
5. The first tweet is free. If you like the demo, add 10 credits for $10. I'll be grateful for your support. Cheers.
