How can this be done?

[BitcoinGirl.Club]

I do not want to go off-topic, but that is wrong. The majority of "regular" email systems do not use encryption in the backend and all messages are still stored in cleartext form on the servers. Trust me, I was a sysadmin for years. 

I was away yesterday but I was reading your response and Googled some articles about email security for different email services. I had a wrong idea that Google do PGP encryption but knowing they don't, just broke my trust. You are right most regular email system don't. Protonmail has it as an additional feature, which needs additional setting to enable it in your end. And if the receiver do not have the same setting then they will not be able to read your email. It become complicated when the email is sent to another service instead of proton to proton.

Correct me if I'm wrong both of you:

Poker Player, if you want to add a timestamp to your message, I suggest that you incorporate the block number and the nonce from the last mined block into the message. When you publish the signature/hash of the message, you also publish the block number and nonce that will be in the message. That way, you will have another provable way of confirming when the message was created.

I understand that would confirm that the message was signed at least when that block was mined or after, and not before, but it could have been created after.

Do make sure that the post is / won't be edited; that's just one thing I'd try to make sure of. Or someone archive the page just in case there will be doubts in the future.

That can be seen in https://loyce.club/archive/posts/ and some other page. Messages are automatically archived when they are created.

Note: I had posted this message earlier but forgot to put "Signed message will be revealed on 10/31/2022" outside the message. I thought it was better to delete it and post it again rather than edit it.

That is true. That's why I said that you should make the block nonce public along with the digital signature of the message. There is no way to know the nonce of future blocks.
But I agree that it's not really necessary, unless you want to add a timestamp to the message.

That's right. Most regular email providers use only transport-level encryption, or TLS (SSL) layer over the plaintext communication, which means that the message is protected from eavesdropping only during transit between individual SMTP relays, but not all the way between the sender and the recipient.

Address staked here.

The usual format of what you have quoted includes the address as part of the signature, like so:

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----

-----BEGIN SIGNATURE-----
bc1q2z248q6kaasd549pjunjd6740hlf50wkvcu9s0
IIVa9HxfBRnnOFfks0sRBqlK5vd9tOzh6zgA6L6OFLfjCedQocGY6jxeg7tJLAnPKJrAk0RCf1rV6A6ZSALY9tA=
-----END BITCOIN SIGNED MESSAGE-----

This is important because the same signature can be used to verify any message, if the address is not specified. I know you've included a link to a post containing the address, but better to include it directly in the signature and allow another user to quote it so it is easy to prove it has not been edited.

That is true. That's why I said that you should make the block nonce public along with the digital signature of the message. There is no way to know the nonce of future blocks.

But doing this only sets a lower limit of when the message was signed. It could not be signed before the block in question was found, but it could easily have been signed any time after the block in question was found. To set an upper limit he either posts it publicly here on the forum, or for absolute proof includes a hash of his message in an OP_RETURN output and commits it to the blockchain.

Check what I did for this game.

I sent a self message with the number of reports I made so far. In case it requires to prove then the PM will be reported to the staff.

This could work for you too. It's the easiest I think 😂

I thank you for the suggestion, but if with something as simple as posting a signed message without fully revealing it I have made mistakes like this one, and this one, and considering that I had previously signed and verified messages, I think it is better that this time I focus on option 2 that NeuroticFish commented.

Let's see if this works, if it does, the only thing I'll have to do in the prize thread will be to include the address, as o_e_l_e_o comments, and that someone quotes me as soon as I publish it.

Quoting the signature. Is it final?

[LoyceV]

Let's see if this works

It works

I verified the signature with Electrum and confirmed the archived address.

[o_e_l_e_o]

Quoting the signature. Is it final?

That signature verified the message provided (Blah, blah, blah), so won't be the final signature for the prize thread.

Let's see if this works, if it does, the only thing I'll have to do in the prize thread will be to include the address, as o_e_l_e_o comments, and that someone quotes me as soon as I publish it.

Pretty much. The addition of both Loyce's and TryNinja's archive sites provides additional redundancy and proof that things haven't been edited. And obviously remember to keep an exact copy of the message, since even a single character being changed will result in an invalid signature.

I will start with the fact the signature of this last message doesn't match the first signature posted (28 oct), but it does match the second (30 oct). And also verifies it.
So while you should be careful to have the same signature all along, you seem to have understood the things and done it good.

I guess you missed that I didn't save the first message.

I think I will do it next week, as I see that there is an envious person who wants to compete with me and has gone ahead of me. 

Will publish the partial message here and when quoted I will create the thread in Games and Rounds.

I know who you are talking about. It's done 🤣
You are too late, screw you 😘

But to be honest I did not have your topic in mind. I think some users are too interested with reporting stats. It's like they want a recognition when they are doing every little bits LOL
The idea of the game was instant just to tell them from years in the community many members never cared about such stats and shout out even if they are constantly reporting. Everyday we long in, have fun, logout and go to sleep. Almost a decade. Sometimes we get bared and give it a break.

After I have the post, I was thinking how would I prove, then I stole the idea we were discussion here 😉
