The timestamped file:

N.b., the signing time was 2020-10-24 22:51:37 UTC.  I just waited for the timestamp to get confirmations, this time around; then, I forgot to post it.  Why bother making another one.

Skip to the part that you should really want:  Verification bits!

V8s:  LOL. 😺

Thanks, johhny.  I am not really back, or not supposed to be; it is why my activity is kind of all in one place lately...

About bitcoin keys is this joke or not, eh?  Tongue Will try to recover it a little bit later.

Hah, made you look!  Well, that was the point.

I said that I was tempted.  If I really wanted to pay people to embrace cryptographic security, then—why, then I would spam a PGP 256% airdrop bounty signature campaign in the altcoin get-rich-quick forum!



So, anyone else up for doing the most advanced, temporally enforced crypto-forum crypto-key stake yet invented?

Feedback would be good.  How best could this work for you?  I sort of still a little bit idealistically hope to eventually someday develop this concept into something that people actually use.  Wow, such many qualifiers.

Crypto for the Crypto Throne!
Editorial comment:

To test if anybody actually verifies, I am tempted to salt this with fake information—or perhaps to conceal herein the private keys for some Bitcoin.  I fear that the latter would be safer than cold storage on an airgapped machine in a bunker beneath the Alps.

Nice to see you here again (only now i've found that you returned to this forum again).

The timestamped file:

Code:
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

I am Bitcoin Forum user 976210.

To provide evidence that this is not an old message previously signed
and forward-dated, I will hereby cite a few of the most recent posts by
theymos (weaker evidence, especially since he hasn’t posted in a few
days), and the ten most recent Bitcoin block hashes (stronger evidence!).

To prevent this message from being altered and backdated in the future,
I will timestamp it with Peter Todd’s OpenTimestamps service.  This in
itself will provide security incomparably superior to the forum tradition
of “quote and archive”.

I will NOT hereby state the signing time, or the identity of the signer.
You should obtain this information from the PGP signature on this message.

If you don’t do PGP, you don’t do crypto!
For the purpose of proving that a digitally signed statement has not been backdated, I hereby present a tool far superior to quoting and archiving:  Secure, trustless timestamps using the Bitcoin blockchain!

Understand what OpenTimestamps does and does not prove.  Peter Todd’s announcement blog post provides an excellent introduction.

In the digitally signed message presented below, I include recent information that would be infeasible to predict.  This prevents forward-dating, which OpenTimestamps itself does not prevent.  The information within the message is strong evidence that the message was created and signed not significantly before its alleged creation time; the timestamp trustlessly, verifiably proves that the message was created and signed not significantly after its alleged creation time.

The magic bits are contained in an OP_RETURN in txid:
134da08e1590e709f3904e91e05de0e839bab18c5ad456471d0f3c84f374ae20
Need a handy explorer link?  See Blockstream.info (Javascript required; onion).

As a practical matter, the only thing that you that need to verify the timestamp is the timestamp file that I have base64ed below (plus of course, the timestamped file).  You can verify this locally, using the OpenTimestamps client plus your own Bitcoin node, or verify it on the OpenTimestamps website if you trust it to tell you the truth. :-)

The timestamped file:

Code:
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

I am Bitcoin Forum user 976210.

To provide evidence that this is not an old message previously signed
and forward-dated, I will hereby cite the three most recent posts by
theymos (weaker evidence, especially since he hasn’t posted in a few
days), and the ten most recent Bitcoin block hashes (stronger evidence!).

To prevent this message from being altered and backdated in the future,
I will timestamp it with Peter Todd’s OpenTimestamps service.  This in
itself will provide security incomparably superior to the forum tradition
of “quote and archive”.

I will NOT hereby state the signing time, or the identity of the signer.
You should obtain this information from the PGP signature on this message.

I waited for this to get sufficient Bitcoin confirmations that it may be considered to be reliably buried.  I also “upgraded” the file, so that it contains all the information that you need to verify it with reference to the blockchain.  You will be able to verify this timestamp even if the OpenTimestamps website and the calendar servers all disappear.  As long as Bitcoin exists, this timestamp will remain secure and trustlessly verifiable.

See also relevant technical discussion of the future of Nullian Verification.


I now invite others to post their own verification statements on this thread.  If I can get at least a few others doing this regularly, then I will start a git repository with timestamped signed attestations of my own observations of what was posted by what account, and push it to Github.  That way, everybody will be able to pull all of the substantive data from this thread (including a collection of PGP keys) conveniently, without tedious and error-prone copying and pasting from a forum thread.

Please refer to my 2020-04-28 statement for a reference on how this should be done.  Expressed in pseudocode, v0.0.1-alpha of the required format is:

Code:
"Bitcoin Forum name:\t[your name]\n"
"Bitcoin Forum userid:\t[your userid]\n"
"PGP primary key:\t[your PGP fingerprint]\n"
"\n"
"# Ten most-recent Bitcoin block hashes:\n"
"\n"
"[height]\t[ISO date]\t[hex hash]\n"
[...]

That is human-readable; and I think that it should be not too horrible to wrangle with /bin/sh and standard shell tools.

DO NOT include the date, which is contained in the Signature Creation Time subpacket of your PGP signature.  DO NOT include any other extraneous data that may confuse scripts.

Include a complete OTS file, base64ed in a separate block.  Posts without a timestamp file will be deleted.

For your first post on this thread, and any time that your PGP is updated, please include your PGP key in a separate block.  If desired, you may also include links to archival evidence that you have previously claimed the same PGP primary key with the same forum account; if you do, keep any descriptions concise and factual.

I plan to invite third parties to attest which accounts they see posting what; however, that will need to wait for me to develop a reasonable format for it.  DO NOT quote other people’s posts here; quote-posts will be silently deleted.

DO NOT post claims to have verified others’ signatures and timestamps!  Such claims encourage newbies to believe Gavin-style fake “verifiations”.  I will delete all such claims from this thread.

Anybody may post properly formatted verification statements, timestamps, and PGP keys on this thread.  However, all discussion is off-topic; posts containing any kind of chit-chat will be deleted without comment.  If you wish to engage in expert-level technical discussion of a better way to do this, please take it up on my relevant thread in Development & Technical Discussion.  Otherwise, please wait for that better way to be developed.



Original post text, with updated list of links to statements:


Much have I complained about the ad hoc security measures in the various “stake” threads.  Well, I should offer a better solution.  Here it is—at least, the start of something better.  I intend to do this semi-regularly—at least once per month, unless I am “sleeping”.

If my forum account has posted recently, and significantly more than a month has passed since this thread was refreshed with a new PGP-signed, OTS-timestamped message containing verifiably recent information, then you should demand a fresh statement consistent in its evidentiary strength with the statements that I have previously provided.  Be very suspicious if the demand is refused or ignored.

I intend to refine my way of doing this, based on future experience.  If or when I work out a standard format that is relatively easy for others to fully verify, then I may open a new “stake” thread where quoting is prohibited as spam, and trustless, cryptographically verifiable evidence is required in a standardized, easy-to-verify format.



Verification statements (listed in reverse chronological order):




Local rules:  Only the following are on-topic in this thread.  Anything else will be silently deleted as off-topic.

  • New signed and timestamped statements from me.
  • Smart questions stated with at least ordinary social courtesy.
  • Competent technical questions, comments, suggestions, or critiques.  I welcome competent technical discussion!  However, I am currently out of patience with people who make repeated incorrect assertions out of ignorance, even when I provide something tantamount to a free tutorial.

Do not publicly say that you have verified a statement.  This gives a false sense of security, and tends to inculcate in the public a habit of relying others to “verify”, instead of verifying for themselves.  This is crypto!  It is supposed to be trustless.  Discussion of how to verify these things is welcome—claims that you have verified something are not.

If you want to post a similar statement yourself, please e-mail or PM me first to discuss it.  The way that I am doing this is admittedly a bit rough; and I don’t want to start a trend before improving that, perhaps with your suggestions.  Thanks.
