Zero-knowledge proofs are cryptographic techniques that allow a prover\nto convince a verifier that certain statements hold, without providing\nany additional information. They are becoming increasingly popular in\nthe blockchain space, as they provide solutions to overcome inherent\nweaknesses of blockchains: as they assume a complete lack of trust\nbetween participants, every calculation has to be replicated by\nmultiple parties, which leads to poor efficiency. Also, blockchains\nprovide a shared public ledger, which by default is lacking any\nprivacy.\n\nIn this presentation, we will discuss zero-knowledge succinct\nnon-interactive arguments of knowledge (zkSNARKS). Using the mina\nblockchain and smart contract system as an example, we will show how\nthey can be used to efficiently create trust in an untrusted\nenvironment. We will also look at how they allow creating applications\nwith a programmable degree of privacy.\n\nWhile zero knowledge techniques are a perfect match for blockchains,\nand they are rapidly gaining traction in that industry, their\nusefulness goes beyond that. The goal of this presentation is to\nintroduce the audience to the concept of zero knowledge proofs, and\nprovide a basic understanding and intuition of how they work, and\nunder which circumstances they can be useful.\n\t\nabout this event: https://bobkonf.de/2024/kant.html
