Aligned is designed to verify zk proofs cheaply, with high throughput and low latency. However, any existing mechanism that can guarantee computation integrity can be used in Aligned. For example, trusted Execution Environments (TEEs) like SGX, can also provide an efficient way to guarantee a computation was done correctly. This

In recent months, we have witnessed the development and enhancement of general proving virtual machines such as Risc0, Valida, Jolt, and SP1. These innovations allow users to write ordinary code in languages like Rust or C and generate proofs demonstrating the integrity of computations. This evolution is poised to transform

Elliptic curve pairings play an important role in Ethereum’s Proof of Stake and in proof systems such as Groth16 and Plonk. They allow us to perform some sort of encrypted multiplication, crucial to aggregatable signatures and some polynomial commitment schemes. However, pairings seem shrouded in mystery and complexity.

The Sumcheck protocol is an efficient tool to develop succinct arguments. It is relied upon by many proof systems, such as Lasso/Jolt by a16z crypto, HyperPlonk, Binius, Spartan, and GKR. Sumcheck was first proposed by Lund, Fortnow, Karloff, & Nisan in 1992. The sumcheck protocol is an interactive protocol

SNARKs have gained considerable attention recently due to their broad utility in areas such as blockchain scalability, identity mechanisms, verifiable machine learning, and fighting against misinformation and fake news. We see new developments daily, but SNARKS have been around for a long time. SNARKs allow one party, the prover, to

Authors: Roberto Catalán and Federico Carrone Bridges are generally insecure and economically inefficient. They exhibit an asymmetry between users and bridge operators, where users can easily lose funds. We propose a bridge design that is simple, modular, and utilizes multi-storage proofs and the native messaging system between Ethereum and Layer
