Common Prefix

The prerequisite for ledger safety

Common Prefix is a team of engineers and scientists committed to pioneering advancements in blockchain technology. We specialize in bridging the gap between academic rigor and industry practices focusing on Layer-1 and Layer-2 technologies, interoperability, scalability, and usability of distributed ledgers.

In partnership with leading networks such as Axelar, Babylon, Celestia, Harmony, MystenLabs and Snowfork we actively utilize our GitHub organization to share cutting-edge projects developed by our team. We believe that open-sourcing projects and ideas cultivates a collaborative environment that rapidly propels the blockchain community forward.

Some of the projects that we're currently building are:

  • Axelar light client: An Ethereum prover/verifier implementation of a light client that employs the Sync Committee protocol of Ethereum to bridge events from Ethereum to Axelar with existential honesty assumptions.
  • State prover: A simple API for generating proofs from the Ethereum beacon state using a Lodestar node.
  • Block roots archive: A caching layer including a data scraper and a server designed to aggregate and provide access to all the block roots within a single Sync Committee period of the Beacon API of Ethereum.
  • Axelar <> XRPL Integration: An integration of Axelar with the Ripple Chain consisting of a relayer and the contracts.
  • Ancestry Prover: An all-in-one solution for proving that a beacon block is a predecessor of another beacon block.
  • Patronum: An Ethereum RPC proxy that verifies RPC responses against given trusted block hashes.
  • Kevlar: A CLI tool that utilizes Patronum to run a light client-based RPC Proxy for PoS Ethereum. Kevlar can be used to make Metamask or any RPC-based wallet completely trustless.

Projects developed by us, hosted on other organizations:

  • Flare Wraps: A multisig-based ETH <> Flare bridge currently holding more than 3M USD TVL, consisting of a validator and the contracts. Developed in collaboration with Ēnosys,
  • Phygitals: A production-ready implementation of the Ermis protocol, that enables users to redeem NFTs on-chain and get the corresponding physical item delivered by the vendor – all without implicating any third-party service. Developed in collaboration with Ēnosys.
