Signing a message with a time stamp ?

[ajareselde]

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-----

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.

Can't you include the signed message in a small transaction?
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.

Transactions don't have timestamps. The only thing that indicates time in a transaction is the timestamp of the block that it was included in.

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.

What time stamp? Its a reduce of time

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to the OP yes simply adding that signature as extra data to a tx, when finally locked into a block, will then give it a historical reference (using the blocks stamp)

This is exactly what i wanted to know, thank you.

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