| > It is a different level business can be done at. With blockchain we don't trust anyone anything and can prove everything. No. Anything that is not produced directly on the blockchain cannot be trusted and is not provable. With "proving who you say you are", you cannot prove anything, since you need an off-chain verification saying "Yep this guy is jakupovic because I can see it on his ID". All you can prove on the blockchain is that someone that has access to the address f9c979ebe8cda1f345b has signed a contract. This doesn't tell you that jakupovic signed, because there is no way to prove on chain that f9c979ebe8cda1f345b is owned by jakupovic. Similarly, there is no on chain way to prove that f9c979ebe8cda1f345b is NOT owned by jakupovic. Before you bring up having the private key, having the private key means nothing more than "I have the private key". It doesn't mean that the key is really yours, and it doesn't mean that someone else doesn't have the key. ----- People have been conned in believing that "This business is using blockchain" is a viable basis for investing into said business. But everyone would laugh if someone said "You should invest in this business because it's using MySQL". "We use blockchain" is as much a selling point as "We use Swagger". If you believe otherwise, you have been conned. |
Here if jakupovic == f9c979ebe8cda1f345b then anything signed by f9c979ebe8cda1f345b is the same as being signed by jakupovic in the eye of the law and the blockchain used, also not a lawyer here. For example clicking I agree on an online form is the same as signing a contract, but neither of these can really prove the person "signing" is really who they say they are unless someone is sitting there checking their ID during the signing. This ID checking part is the crypto land promise and not currently possible with tech we have, short of someone sitting there.
