A Vamp-IR's Guide to Arithmetic Circuits (and Perfectly Boiled Eggs)

A primer on the concept of arithmetic circuits. We will take a look at what arithmetic circuits are, what they are used for, what tools are there for working with them, including the tools we develop here at Anoma, and what we can do with the circuits using these tools.

Hash Functions in Plonkup

A quick overview of the proving system and show how to write a circuit that computes a small part of a common hash function that benefits greatly from the inclusion of lookups alongside arithmetic gates.

Distributed Systems

Heterogeneous Paxos and Multi-Chain Atomic Commits

Heterogeneous Paxos exploits the high intersection between validator sets of different blockchain to create a heterogeneous consensus protocol for atomic multi-chain transactions & extends the capabilities of IBC to allow for arbitrary communication between chains within an atomic transaction

Ferveo Cryptography Overview

Ferveo includes a custom-designed distributed key generator & custom-designed threshold decryption scheme intended to meet the performance & security requirements of the underlying consensus mechanism.

Demystifying recursive zero-knowledge proofs

Recursive zero-knowledge proofs are new cryptographic primitives relevant to the Anoma blockchain use case. In this article, we investigate the possible alternatives for verifying blockchain circuits efficiently. Our main interest is in estimating the efficiency of pairing-based constructions.

Demystifying ZEXE

ZEXE is a ledger-based system that allows for the running of multiple applications atop the same ledger in a way that transactions reveal no information about the particular computations which are performed.

Side-channel analysis for distributed ledgers

Introducing side-channel analysis/attacks (SCA) and counter-measures and to provide directions that can help security assessments take them into consideration. Side-channels are relevant to cryptographic implementations, and as such they introduce a class of attack vectors in the blockchain context.

Demystifying HybridDKG - A Distributed Key Generation Scheme

HybridDKG is one of the latest distributed key generation schemes and can operate in an asynchronous environment, making it the most viable DKG scheme to use over the internet.

Demystifying Aggregatable Distributed Key Generation

A novel component of Anoma is a Distributed Key Generation (DKG) scheme. George Gkitsas describes the concepts in DKG, starting with simple constructions, building up to the aggregatable DKG.
