Cryptoeconomic Security for Data Availability Committees

Layer 2 systems have received increasing attention due to their potential to scale the throughput of L1 blockchains. To avoid the cost of putting data on chain, these systems increasingly turn to off-chain dat...

Powers-of-Tau to the People: Decentralizing Setup Ceremonies

We propose several decentralized ceremonies for constructing a powers-of-tau structured reference string (SRS). Our protocols make use of a blockchain platform to run in a permissionless manner, where anyone c...

Arithmetic Sketching

This paper introduces arithmetic sketching, an abstraction of a primitive that several previous works use to achieve lightweight, low-communication zero-knowledge verification of secret-shared vectors. An arithme...

HyperPlonk: Plonk with Linear-Time Prover and High-Degree Custom Gates

Plonk is a widely used succinct non-interactive proof system that uses univariate polynomial commitments. Plonk is quite flexible: it supports circuits with low-degree “custom” gates as well as circuits with ...

A Lower Bound on the Length of Signatures Based on Group Actions and Generic Isogenies

We give the first black box lower bound for signature protocols that can be described as group actions, which include many based on isogenies. We show that, for a large class of signature schemes making black ...

Threshold Signatures with Private Accountability

Existing threshold signature schemes come in two flavors: (i) fully private, where the signature reveals nothing about the set of signers that generated the signature, and (ii) accountable, where the signature co...

Halo Infinite: Proof-Carrying Data from Additive Polynomial Commitments

Polynomial commitment schemes (PCS) have recently been in the spotlight for their key role in building SNARKs. A PCS provides the ability to commit to a polynomial over a finite field and prove its evaluation ...

An Airdrop that Preserves Recipient Privacy

A common approach to bootstrap** a new cryptocurrency is an airdrop, an arrangement in which existing users give away currency to entice new users to join. But current airdrops offer no recipient privacy: they ...

Zero-Knowledge Proofs on Secret-Shared Data via Fully Linear PCPs

We introduce and study the notion of fully linear probabilistically checkable proof systems. In such a proof system, the verifier can make a small number of linear queries that apply jointly to the input and a pr...

Post-quantum EPID Signatures from Symmetric Primitives

EPID signatures are used extensively in real-world systems for hardware enclave attestation. As such, there is a strong interest in making these schemes post-quantum secure. In this paper we initiate the study...
