One beautiful morning, while he was absentmindedly looking out the window with a cup of tea, the world's No. 1 art appraiser was carried away.
There are two identical paintings of Mona Lisa, one is real, the other was painted by a thief and he marked the fake in a place no one knows.
The requirement for the art appraiser who is being controlled by the thief is how to tell him which painting is real without revealing the distinguishing characteristics. Because if it is revealed, the thief will edit the fake picture and next time it will be impossible to distinguish.
The solution to this situation is a clear example of the application of Zero-Knowledge.
The art appraiser asked the thief to place two paintings side by side and would point out which one was real without telling the thief why it was real. Next, the appraiser covered his eyes and asked the thief to reverse the positions of two random paintings many times, then the appraiser continued to point out which painting was real. Repeat the job over and over until the thief is satisfied.
Thus, the appraiser successfully showed the real painting but did not reveal any identifying features. That is a form of proof in engineering #ZeroKnowledge
At this point, you must have understood the power and potential uses of #ZKP. Applied in Blockchain, it allows to authenticate transactions without having to reveal too much information about those transactions - Magic yet :))) From there, bringing security to transaction data.
It's no coincidence that #VitalikButerin included Zero-Knowledge in the original network update roadmap #Ethereum
We will see this interesting example again in Part 2 of the article series: "Finding the trend that will lead the crypto market next season".
