Lumoz is a Modular Compute Layer and ZK-RaaS (Zero-Knowledge Rollup as a Service) platform. It uses a hybrid consensus mechanism combining PoW (Proof of Work) and PoS (Proof of Stake) to provide zero-knowledge proof (ZKP) arithmetic for ZK-Rollup. Lumoz offers Web3 developers the ability to generate zkEVM application chains with a single click, addressing the substantial computational power needed by multiple ZK-Rollups and creating a beneficial mining environment for global miners. ^[1][2]

Overview

Founded in March 2022, Lumoz's ZK-RaaS (Rollup as a Service) service allows developers to launch their zkEVM chains quickly without needing detailed knowledge about ZK or chain nodes. The platform also supports a ZK-PoW concept, inviting miners to maintain zkEVM and calculate ZKPs. Lumoz aims to simplify ZK-Rollup usage and promote wider adoption, facilitating the large-scale deployment of zkEVM-based application chains. For miners, Lumoz serves as a multi-chain PoW protocol, supporting ZK mining and generating zero-knowledge proofs for ZK-Rollups across various public chains. ^[1][2]

Funding

In March 2024, Lumoz raised a pre-Series A funding round at a $120 million valuation. Investors in the round included OKX Ventures, HashKey Capital, KuCoin Ventures, Comma3 Ventures, Kronos Ventures, Kernel Ventures, and Polygon co-founder Sandeep Nailwal. The funding round was sized at $6 million, a source with direct knowledge of the matter told The Block. ^[6]

On May 29, 2024, Lumoz officially announced the completion of a strategic funding round. Participating investors include IDG Blockchain, Blockchain Coinvestors, Gate Ventures, Summer Ventures, EVG, SevenUpDAO, Sweep Ventures, among others. The specific amount of funding remains undisclosed. ^[5]

The Lumoz team revealed that the new funds will be used to further expand the Lumoz team, develop the modular computing power layer, and advance the construction and technological innovation of the ZK-RaaS platform. ^[5]

"After the announcement of the previous funding round, many venture capitalists eagerly approached Lumoz, prompting us to initiate another strategic funding round within a short timeframe. In this round, we have once again attracted a group of exceptional investors and partners who have full confidence in Lumoz's vision, products, and team. They are enthusiastic about providing multi-faceted support, including funding, expertise, and resources, which will undoubtedly have a positive impact on Lumoz's future," - Lumoz CEO & Co-founder Nanfeng said.

Technology

Modular Blockchains

Modular rollup technology provides an approach and solution to address the impossible triangle problem of traditional blockchain. By breaking down the blockchain system into different modules, rollup implements a layered structure to achieve more efficient transaction processing and data management, thereby balancing decentralization, security, and scalability to some extent. ^[3]

Rollup modules typically include:

Settlement Layer

Responsible for updating the asset status of the blockchain, usually operating on Layer 1 (the main chain). It verifies the data submitted by rollup and updates the results to the main chain to ensure the security and accuracy of assets. ^[3]

Execution Layer

Processes transactions on rollup, records, and updates transaction status. It can execute transactions quickly on the rollup network without waiting for confirmation from the main chain, thereby improving transaction processing speed and efficiency. ^[3]

Consensus Layer

Ensures consensus on the status of each transaction, ensuring the legality and security of transactions. It usually adopts efficient consensus algorithms such as Proof of Stake or Proof of Authority. ^[3]

Data Availability Layer

Records all transaction data that occurs on rollup and provides full data when updating asset status in the settlement layer. This helps ensure data traceability and integrity while enhancing system security and reliability. ^[3]

ZK-RaaS

Lumoz deploys a Rollup System Contract (RSC) on each base chain to manage the lifecycle of Rollups, including registration, suspension, and withdrawal. Developers can lease a Rollup slot with MOZ tokens to own a ZK-Rollup. This is similar to a slot in Polkadot or an application chain in Cosmos but more secure and cost-effective due to the use of zero-knowledge (ZK) technology, which ensures shared consensus and data availability. ^[4]

Upon leasing a Rollup slot, developers gain an independent execution environment where they can control a unique ZK-Rollup chain, customize its economic model, and adjust gas fees, even to zero. All hardware resources, including data availability, sequencer, and ZKP computing power, are decentralized and provided by the Modular Compute Layer. ^[4]

Additionally, native cross-rollup communication enables interaction between different ZK-Rollups on the same base chain, enhancing interoperability and reducing asset fragmentation. ^[4]
