In Ignis they use ZK-SNARKs to prove on main chain that the plasma chain is executing the code as agreed by participants. In general, thanks to libraries like ZoKRates (and added support for sha256 recently), the application of ZK-SNARKs is in the reach of possible on Ethereum. There are already PoCs on Reimplementing Zcash on it. See ZKDAI.

python sdk research algorithms ethereum solidity cplusplus-11 zk-snarks pinocchio SNARKs. zk-SNARKs are the cryptographic tool underlying Zcash. They are proofs that you have performed a computation over some inputs without revealing all of the inputs. Zcash uses these proofs to verify transactions while protecting users’ privacy. In Ignis they use ZK-SNARKs to prove on main chain that the plasma chain is executing the code as agreed by participants. In general, thanks to libraries like ZoKRates (and added support for sha256 recently), the application of ZK-SNARKs is in the reach of possible on Ethereum.

An example would be proving that you have enough Ethereum to make a transaction without revealing exactly how much ETH you actually have.

Blockchains are public and need to be trustless, as explained earlier. Zero-knowledge proofs, a board game, and leaky abstractions: how I learned zk-SNARKs from scratch Speaking of the above blog post, this piece is from a coder who used that, among other resources, to teach themselves how to work with zk-SNARKs. This is a great combination of a personal learning journal plus some insights that might help you as well. SNARKs are short for succinct non-interactive arguments of knowledge. In this general setting of so-called interactive protocols, there is a prover and a veri er and the prover wants to convince the veri er about a statement (e.g. that f(x) = y) by exchanging messages.

channels, plasma), by using ZK-SNARKs to mass-validate transactions. Indeed, at Devcon4 – ethereum’s annual developer conference – there was a palpable sense of excitement around zk-snarks and their applications. The event … @Drumsjuanma Christian Lundkvist (Ethereum Dev) has just written up an excellent intro to zk-SNARKS on Ethereum In a word, yes. It offers ways to verify secrets, and that secret doesn't have to be a monetary one.

However, there have been some major flaws. The main problem has been the need for a trusted setup . zk-SNARKs rely on a permissioned private key. Zk-SNARKs researcher Professor Eli Ben-Sasson explains, zk-SNARKs use asymmetric public key cryptography to establish security. zk-STARKs instead requires a leaner symmetric cryptography, namely, collision resistant hash functions, and thus removes the need for a trusted setup.

Jan 19, 2017 · The key to adding such capabilities to Ethereum is zero-knowledge succinct non-interactive arguments of knowledge (zk-SNARKs) - precisely the cryptographic engine underlying Zcash. One of the goals of the Zcash company, codenamed Project Alchemy , is to enable a direct decentralized exchange between Ethereum and Zcash.
