Title: Signing a message with a time stamp ? Post by: ajareselde on December 20, 2015, 11:58:51 PM I want to sign a message, but to also include a time stamp that could be verified, as in ; i want to use blockchain tech to protect author rights.
This may seam like silly, but i never had to timestamp anything. It should look something like this, but have a timestamp as well -----BEGIN BITCOIN SIGNED MESSAGE----- un(wanted) wrote a word filled with grief with my own cant be brief wrote another feels the same letters changed still your name thrill is over truth be told as your love life is sold sweet the tear drawn from eye numb the hope love won't die splash of ink to remember drained thoughts on a paper -----BEGIN SIGNATURE----- 1MZvjgQFQdAUUx5n6Prxw4oGuRycVmaZYR IOE3wAI5Ee7Vk+INJ+ssZ5Oy+RTv0lWAwoZaExqr66ECaHYTxDt13vsKX0wFdRECV+Kbqch/nqs7jJMmeQbN7es= -----END BITCOIN SIGNED MESSAGE----- Title: Re: Signing a message with a time stamp ? Post by: saturn643 on December 21, 2015, 12:19:44 AM What do you mean a "time stamp that could be verified" and "blockchain tech to protect author rights"? The blockchain doesn't use timestamps.
The easiest way to have a timestamp is to literally include the date and time in the signed message. It can be in any format, but it should also indicate the timezone in the timestamp.

That would ensure that there is a time stamp which can be verified (the time at which the transaction gets confirmed). If you have some high priority coins lying around, you can send coins from one address to another. You may not even have to spend anything. Title: Re: Signing a message with a time stamp ?

The only thing that indicates time in a transaction is the timestamp of the block that it was included in.That would ensure that there is a time stamp which can be verified (the time at which the transaction gets confirmed). If you have some high priority coins lying around, you can send coins from one address to another. You may not even have to spend anything. Also, to encode data in transactions to store in the blockchain is not trivial and to have all of it in one transaction would probably involve some coins being burned.

Title: Re: Signing a message with a time stamp ? Post by: franky1 on December 21, 2015, 05:02:18 AM i think the OP doesnt mean a timestamp of a tx.. but more so using data in a tx, confirmed to a block to validate a time.
eg if a block made at 10:05 on december 20th, includes a tx that has extra data of "a poem of flowers by ajareselde" then that in itself proves that the poem was available/public from atleast the 20th of december at 10:05 then if someone else claims they made a poem "a poem of flowers" on new years day.. using some other proof, ajareselde can show he made it on december 20th so to the OP yes simply adding that signature as extra data to a tx, when finally locked into a block, will then give it a historical reference (using the blocks stamp) Title: Re: Signing a message with a time stamp ?

Locking this now as my question has been answered in full. |
