Title: Bitchain Messenger Post by: sp1d3rx on August 24, 2012, 11:59:27 PM I was wondering about making a "bitchain messenger" that allows you to send messages to others and then those messages are signed and encrypted into the bitchain? Sort of like how bitcoin sends coins - you'd be sending text messages (like twitter). Each message would cost 1 coin, but it could be a relatively cheap coin like LiteCoin - and when you send a coin, you also have a space to send a message. You'd have anonymous messaging and currency. So, for example you could order something and include your shipping address with your payment. Or perhaps just use it as a jabber replacement. Messages would only be delivered after 6 or so confirmations. You could for example place a bet by sending a coin (and your message would include the pay-to address so you could get paid if you won the bet). You could play chess online by sending the moves (ex: Rb3 Na1) and you couldn't take back moves or cheat.

This would in effect be like P2P email, where the message gets encrypted and stored in the bitchain - call it a mailchain. Would be interesting for messages which need to act as proof under certain circumstances. E.g. legal contracts. Then the chain can act as a timestamp which cannot be falsified. It would be a decentralized notary. Since the chain only has to be self-sufficient you could have a constant coinbase transaction per block which equals the amount of available bytes in a block. E.g. if you set the hard limit to 1MB. you allow the generation of 1M coins per block. Then a message costs exactly it's amount in bytes - otherwise a miner should reject the message.

Some of the posts met my concern that including the messages directly in the bitcoin blockchain will hijack it for a different purpose. The you have a problem if the two applications have different computational complexities. Title: Re: Bitchain Messenger Post by: chriswen on August 25, 2012, 02:26:58 AM Yeah, it'll be available for anyone to see. Also, that would be awfully expensive for a mail client. $11 for anonymous mails???

Proof of concept is here and it only cost BTC .005 : http://people.scs.carleton.ca/%7Eclark/projects/commitcoin/ |
