> How to prove you know a secret without giving it away
This is the best use case for blockchain. Put the secret on the blockchain and show others that transaction. Since it's on blockchain, no one can deny your claim about knowing the secret. This is why blockchain was invented.
Before blockchain, I was miserable. There was no way for me to prove to my girlfriends that I knew a secret, without telling the secret. Now with blockchain, my life is so easy - I just show them the blockchain transaction and they know that I know.
- SV_BubbleTime 4y agoI assume this is excellent satire, but you never really can tell.
- fortuna86 4y agoYou really can't..
- nayaketo 4y ago> Before blockchain, I was miserable. This part gives it away. Also his username which is probably misspelled deliberately.

- sdoering 4y agoIf all you have is a hammer every problem looks like a nail. Thanks for this grandiose piece of satire.
- Huh1337 4y agoWell this actually is a good usecase for blockchain, though... The very original Bitcoin client contained this functionality already. Very ironic usage of this quote, imho. Almost like - "even a broken clock is correct 2 times a day"
- getcrunk 4y agoI bet $1000 that this is an ai bot. Hn should have a bot that bans bots
- scifibestfi 4y agoHow can you tell with that level of confidence?
- nscalf 4y agoHe put it on the blockchain to prove he knows the secret. Can’t be wrong, it’s immutable.
- IncRnd 4y agoHe can tell, because he has a secret bot detection bot. That bot can detect 100% correctly with no false-positives, as long as he never reveals how it operates. The bot is named ZeroK.
- raverbashing 4y agoHe doesn't need to, he only needs to be confident that someone with more knowledge (or confidence) in the actual status of the commenter won't make a counter-bet

- eru 4y agoI would like to take the other side of that bet.

- jraph 4y ago> Put the secret on the blockchain and show others that transaction You missed the "without giving it away" part.
- littlecranky67 4y agoExcept that any of the various RFC3161 compliant crypto timestamp services available would have done, too. They are run i.e. by the Swiss Post (commercial), or the german DFN (a non-profit conglomerate of german research facilities and universities). So you could show your girlfriend the crypto timestamp with its included Hash, and also proof you had the secret at a specific point in time, without giving it away.
- rullelito 4y agoI guess SHA1 isn't cool anymore?
- redrobein 4y agoDuring the old forum mafia days message digests were one of the ways people made predictions that you'd reveal later. You would usually tack on something random at the end to make guessing hard.
- Double_a_92 4y agoNot sure if you are trolling? If the secret is on the blockchain, it literally becomes public by definition. And if it's encrypted somehow, what is the point of the blockchain? You could just send an encrypted document to all the relevant people, and later on give them the key. At best the blockchain would prove that you actually send it to them (or everyone in that case), but nothing else.
