Title: How long can a "Public Note" be? Post by: OROBTC on February 05, 2015, 06:58:08 AM ...
I am curious to know how many alphanumerics can "ride along" a BTC transaction ("Public Note"). Here is an example (hash code for this transaction) of a small BTC transaction with a Public Note (perhaps best viewed at blockchain.info): 798b90badb81492b35ac2f98b1d6b742edd3da490a99f7b48588655f91ad6841 Here is the message (about 39 characters, went through OK): HowManyCharactersCanRideAlongAsALabel? EDIT: Perhaps using hash codes as the Public Note is what factom.org (http://factom.org) has in mind for using the blockchain to store their large quantities of information without making the blockchain too bloated (?) factom.org is an interesting little start-up.

Post by: MineForeman.com on February 05, 2015, 07:01:55 AM No idea, but remember, the "public note" feature is only available on blockchain.info and wont be seen anywhere else. (I personally dislike it as I think it encourages blockchain spam)
It is not stored in the real blockchain. Title: Re: How long can a "Public Note" be? Post by: geforcelover on February 05, 2015, 07:02:40 AM ...

@ MineForeman.com It looks like MultiBit will allow a "Label" too, I tried to send something out from my 11-cent balance there at MultiBit, but forgot the password... I do not know if any other blockchain watch programs will allow viewing a Label. Title: Re: How long can a "Public Note" be?

I do not know if any other blockchain watch programs will allow viewing a Label. Most wallets allow a local label to help you remember which address is for what. That has nothing to do with the data stored on the actual blockchain. Title: Re: How long can a "Public Note" be? Post by: OROBTC on February 05, 2015, 07:17:05 AM ...
shorena & MineForeman.com Thank you for the information! Title: Re: How long can a "Public Note" be?

I do not know if any other blockchain watch programs will allow viewing a Label. Never used MultiBit so I would not know. There is only one place you can put arbitrary data into a transaction and that is the OP_RETURN script that currently takes 40 bytes (soon to be 80). So you will get 40 ASCII character into it if you really wanted. (80 soon). I have a feeling though that OP_RETURN is going to be abused and it might not be around for long. |
