Axiom

ZK-powered historical Ethereum data access

Overview

Company Does Not Provide H-1B Sponsorship

Axiom provides a platform-as-a-service that lets Ethereum developers access and compute historical on-chain data (transactions and receipts) using Zero-Knowledge proofs to verify results. Developers send queries to Axiom, which processes them and returns verifiable results via ZK proofs back into the developer’s smart contract, ensuring data integrity with Ethereum-like security. The product differentiates itself by offering verifiable, trustless access to the entire history of Ethereum data at scale, instead of just current state, and charges fees per query based on complexity and resources. Axiom’s goal is to give dApps a scalable, secure way to query and rely on historical blockchain data with cryptographic guarantees.

Simplify's take

What believers are saying

  • Axiom released OpenVM 2.0 to production on July 10, 2026.
  • Lighter EVM devnet launched October 16, 2026, proving commercial distribution.
  • Axiom's AI auditor found Starknet stwo vulnerability on July 27, 2026.

What critics are saying

  • Succinct, RISC Zero, and Scroll compress Axiom's zkVM moat by late 2026.
  • Lighter EVM ties adoption to one partner; partner renegotiation would hit revenue immediately.
  • OpenVM commoditization kills the Axiom Proving API if benchmarks stop leading by 2027.

What makes Axiom unique

  • OpenVM proved Ethereum mainnet live on EthProofs by October 2025.
  • Axiom 2.0 reached p99 Ethereum proving with sub-300 kB proofs in January 2026.
  • Axiom formally verified OpenVM Keccak and SHA-2 circuits in August 2026.
