Prove-it, Blockchain-it: ZKP in Action

Prove-it, Blockchain-it: ZKP in Action

Here is the video of a meetup we hosted recently in our offices in Tel Aviv. Part of the QED-it team (Jon, Kobi & Daniel) presented the applications of cryptographic Zero-Knowledge Proofs on the blockchain. We discussed the theoretical and practical aspects of this powerful tool along with a solution to the “Sudoku purist” incident in the 2013 International Sudoku Championship. During the competition a 100×100 sudoku puzzle was tweaked to have no solution, by a fanatic who believed that sudokus should only be 9×9. The participants spent hours trying to solve it, without realizing that the puzzle had no solution. The sudoku competitors decided that they would not participate again until they could be assured of the existence of a solution.
