Zero-knowledge succinct non-interactive argument of knowledge (zkSNARK) allows a party, known as the prover, to convince another party, known as the verifier, that he knows a private value v, without revealing  ...  In particular, we propose a secure multi-party proof generation algorithm where the prover can delegate its task to N servers, where (i) even if a group of T ∈ℕ servers, T≤ N, collude, they cannot gain  ...  Micali [4] has developed zero-knowledge succinct non-interactive argument of knowledge (zkSNARK), which is a type of zero knowledge proof systems in which the prover just sends one message to the verifier  ...

A Privacy-preserving Outsourcing Scheme for Zero-knowledge Proof Generation

We propose a privacy-preserving scheme to outsource zero-knowledge proof generation to a party that we call a worker.  ...  Our scheme can be applied to zk-SNARKs with a trusted setup, zero-knowledge proofs deployed in many applications.  ...  For example, one can use a distributed zk-SNARK system DIZK [24] to allow proof generation by cluster computing, to outsource proof generation partly to workers.  ...

Time Transitive Functions for Zero Knowledge Proofs [article]

We are proposing the application of VDF for constructing more space time-efficient provers and simulators required for the iterative non-interactive zero-knowledge systems.  ...  Verifiable delay functions have found a lot of applications in blockchain technology in recent times.  ...  Unlike [13] our approach is iterative sequentiality for zero-knowledge proof systems.  ...

Zecale: Reconciling Privacy and Scalability on Ethereum [article]

Antoine Rondelet
<span title="2020-10-16">2020</span> <i > arXiv </i> &nbsp; <span class="release-stage" >pre-print</span>
In this paper, we present Zecale, a general purpose SNARK proof aggregator that uses recursive composition of SNARKs.  ...  Finally, we argue that such scalability solutions for privacy preserving state transitions are paramount to emulate "cash" on blockchain systems.  ...  [WZC + 18] proposed DIZK, a system that distributes the generation of a zero knowledge proof across machines in a compute cluster.  ...
