 A basket full of secret key, or secret shares. Yeah, or secret key. So yeah, we have some private data that we are wondering like, okay, what to do to protect it, do we make up a security solution for it, or do we get some other party to protect it, because it is difficult to do security. So we got like two consultants, actually two cryptographers to consult us, let's call them Alice and Bo. So Alice called us, well, why don't you use like this secret sharing, which is really like, it's great, because you don't have to, well, first Alice called us, don't do it by yourself, because security is hard, just let some other people do it, like outsource it to someone. But it says, okay, it's better not to trust with like a single party, just maybe just secret share your secret and use a few parties, and that will be better. We thought, okay, yeah, that sounds nice. But the problem was, okay, we still have like, okay, now instead of one secret, you have like n secrets, so we still have a problem, because okay, what do we do with this share? Okay, we have to find someone who will say, okay, would you be able to hold my share, or would you, so it's still a problem. So instead of one problem, it's how to protect the secret, we have like n problems how to protect the share. So that was a problem for us, so we went to Bob and said, hey, Bob, what do we do? Because Alice has this great idea, but okay, we are not convinced about it. So Bob said, wait a minute, your secret is valuable, right? So, well, if your secret is valuable, then why don't you just, instead of buying space or buying some service or to protect your share, why don't you just sell your shares? Because that, I mean, it is actually a commission business case study, okay, because it's some valuable share or some secret, so we thought, yeah, that's interesting. So we packaged all this story together, we went to the investors and said, well, yeah, so we have these shares and okay, we'd like to sell them and so on and so on. But then it turns out that, okay, the investors, they have some very interesting requirements. Like there would be interesting, interested to know, for example, they don't just want to give money and just stay in some share there, which doesn't, and in particular, they're interested in growth potential, so they want to, okay, I'm gonna give money, then the share is gonna be, you know, will it grow? Well, in this particular case, literally, will your share grow? So we thought, okay, we don't know about that. Will it grow? So we went back to Alice and said, well, would it be possible to make this share grow, like in some sense, grow in some sense? Alice says, I don't think it can grow, it's not supposed to grow, but I don't know what I can do for you. Alice says, okay, tell us. Well, Alice says, well, I can give you a proof that it cannot grow. Alice says, okay, a proof that it cannot grow. What can I do with a proof that a share cannot grow? Can the proof grow? Alice says, okay, the proof cannot grow, but I can give you as many proof as you want, so that's actually interesting, right? Well, you said, okay, if you give me as many proofs as I want, then I can do something with that, right? So we went, so this is a very nice story, because if we can get it for a share, as many different proofs as you want, and they are all different, you can repackage them, you can install them, and so on. So it's very cool. So, yeah, so it turned out, this is very interesting, and so the investors were happy, the investors were happy, and said, yeah, okay, this is very interesting, I think I'm interested in your shares, actually, I want them all, yeah? So we said, oh, he wants all our shares, that's fine, that's fine, that's brilliant. So we were happy, we sell them all for the shares, the investors were happy. Alice was not happy. I mean, Alice, we went back to Alice, she said, okay, it's crazy, because, well, if you get into the talk, I think this is like, means the entropy of the secret is zero, just to use the vocabulary. So the problem was that, so Alice was not happy, but she was even less happy when she found out that actually the contract, we couldn't even tear down the contract because the contract was already on the blockchain, so we couldn't tear down the contract, we had to tear down the blockchain. So the question is, well, actually, do we tear down the blockchain? Actually, well, we will be happy just to remove our data from the blockchain because the contract is on the blockchain, the shares on the blockchain, so everything. And so I'm almost out of time, I don't have to tell you how we did that, but yeah, we did some research and I can tell you it's, we did find some solutions, but maybe it will be for next time, okay?
