WebMar 16, 2024 · However, in the last few years, researchers have figured out how to combine the sum-check protocol with cryptographic commitments to obtain arguments that are both zero-knowledge and succinct for NP statements. This has led to zk-SNARKs with state of the art performance (e.g., Hyrax, zk-vSQL, Libra, Virgo, Spartan ).

WebOct 7, 2024 · Cryptographic commitments. The commitment is a useful tool in cryptography that is often utilized with the zero-knowledge proof. In principle, the commitment is designed to ensure some values are selected in the correct manner. The description is subtle so let’s consider a concrete case: a ‘Rock Paper Scissor’ game. Let Alice and… WebThey are important to a variety of cryptographic protocols including secure coin flipping, zero-knowledge proofs, and secure computation .

A commitment scheme allows a committer to publish a value, called the commitment, which binds her to a message (binding) without revealing it (hid … WebNov 19, 2024 · Cryptographic agility is the ability to switch to larger cryptographic parameters or different algorithms in the case of security doubts. This very desirable property of cryptographic systems is inherently difficult to achieve in cryptocurrencies due to their permanent state in the blockchain: for example, if it turns out that the employed … WebNov 29, 2024 · New discussion: we propose to study quantum bit commitments not only as a cryptographic primitive in the MiniQCrypt world, but also as a basic (quantum) complexity-theoretic object whose existence is an interesting open problem in its own right. In particular, two flavors of canonical quantum bit commitments can be formulated as two complexity ... the queen\\u0027s gambit amazon
