چکیده
This paper presents a new short zero-knowledge argument for the range proof and arithmetic circuits without trusted setup. In particular, it can achieve shortest size of system categories More specifically, when proving that committed value is positive integer less than 64 bits, except negligible error in 128-bit security parameter, 576 bytes long, which 85.7% previous due to Bünz et al. (Bulletproofs, IEEE Security Privacy 2018). Similarly, circuit satisfiability be proven with communication overhead. Nevertheless, computational overheads both generation verification are comparable those Bulletproofs. Bulletproofs established as one important privacy-enhancing technologies distributed ledger its trustless feature size. has been implemented optimized various programming languages practical usage by independent entities since was proposed. The essence based on logarithmic inner product no zero-knowledge. revisits from viewpoint first sublinear linear algebra Groth (CRYPTO 2009) then propose Bulletproofs+, an improved variety main component xmlns:xlink="http://www.w3.org/1999/xlink">zero-knowledge weighted (zk-WIP) enables reduce proof. It already properties, there additional information reducing zk-WIP, incurs minimal transmission cost during reduction process. Note zk-WIP all characteristics argument, such aggregating batch verification; thus, Bulletproofs+ superior aspects.

Bulletproofs: Efficient Range Proofs for Confidential Transactions
We propose Bulletproofs, a new non-interactive zero-knowledge proof protocol with very short proofs and without a trusted setup; the proof size is only logarithmic in the witness size. Bulletproofs are especially well suited for efficient range proofs on committed values: they enable proving that a committed value is in a range using only 2 log2pnq ` 9 group and field elements, where n is the b...

متن کاملA Distributed Ledger for Supply Chain Physical Distribution Visibility
Supply chains (SC) span many geographies, modes and industries and involve several phases where data flows in both directions from suppliers, manufacturers, distributors, retailers, to customers. This data flow is necessary to support critical business decisions that may impact product cost and market share. Current SC information systems are unable to provide validated, pseudo real-time shipme...
متن کاملUnsound Inferences Make Proofs Shorter
We give examples of calculi that extend Gentzen’s sequent calculus LK by unsound quantifier inferences in such a way that (i) derivations lead only to true sequents, and (ii) proofs therein are non-elementarily shorter than LK-proofs.
