Satoshi codes

Someone had the idea to add numeric codes at the end of transactions to add a special meaning.

Here is the explication that came along with the proposal:

One thing to make Bitcoin more sociable would be to add a message to a Bitcoin transfer. Since this is not part of the protocol, one could have a standard to interpret the last digits sent in a Bitcoin amount, the Satoshis. The digits are currently hardly ever being used and it costs nothing for the computer to use these. People want to express emotions in the messages on computers, that’s where the use of emoticons came from (namely as just simply an interpretation of certain rarely used key combinations).

Therefore I present hereby, Satoshi Codes, the “emoticons” of Bitcoin. You simply add these Satoshis to an amount you are transferring with the following meanings (since Satoshis are currently worth very little it also costs almost nothing).

Here is the list of proposed codes so far:

.. .0 .1 .2 .3 .4 .5 .6 .7 .8 .9
0. (no message) Thank you to our valued customer/recipient Please check your mail. enjoy!/have a nice day I’m sorry!/Sorry for the delay Happy Birthday! For a good friend/friends forever! hugs & kisses with Love
1. Good luck! / (support in general) unused unused unused unused unused unused unused unused unused
2. unused unused unused unused unused unused unused unused unused unused
3. unused unused unused unused unused unused unused unused unused unused
4. unused unused unused unused unused unused unused unused unused unused

6. unused unused unused unused unused unused unused unused unused unused
7. unused unused unused unused unused unused unused unused unused unused
8. unused unused unused unused unused unused unused unused unused unused
9. unused unused unused unused unused unused unused unused unused unused

Notes:

  • Some other codes were proposed in the thread, but it’s difficult to tell which ones are serious proposals, so feel free to add yours if it is. ðŸ™‚
  • Suggestion for adding codes: check your past sent transactions and wonder what message you would have attached to each one. Try to make the message generic enough so that it’s useful to many people while being explicit enough.

Code discussion

Number of digits

For the moment, two-digit codes should be enough, but due to the proposed scheme, it should be easy to add more. Let’s try to keep the list small though, so that they’re easy to memorize without needing software implementation. –Davux 22:14, 19 August 2011 (GMT)

Private codes

Just like unicode characters, maybe a specific range should be reserved for local/private use. –Davux 22:14, 19 August 2011 (GMT)

sort-of Protocol

From the original idea submitter:

You simply add these Satoshis to an amount you are transferring with the following meanings (since Satoshis are currently worth very little it also costs almost nothing.

Alternative idea: just prepend your code with a given number of 0’s (say 4). Backward compatible with the original suggestion, while allowing sub-satoshi amounts when needed.
