New Paradigm of Rollup Platformization: Lumoz's Innovations and Challenges

1. Environment-Driven Rollup Changes

As the number of Ethereum users continues to grow, the network has become increasingly busy, especially during primary offering activities, where gas fees often rise sharply. At the same time, due to the continuous increase in ETH token prices, the high transaction fees hinder the possibility of small transactions. Therefore, improving storage efficiency, transaction throughput, and reducing transaction latency is crucial for the development of Ethereum.

Traditional Layer 1 scaling solutions generally include two forms: On-chain and Off-chain. On-chain refers to updates and optimizations made on Layer 1 by changing the consensus mechanism, implementing sharding, and expanding block size; Off-chain refers to off-chain scaling, which mainly includes sidechains and Layer 2 solutions. The biggest difference between sidechains and Layer 2 is that sidechains rely on their own security protocols, while Layer 2 relies on the security protocols of the mainnet. Therefore, from a security perspective, Layer 2 often has the advantage.

In the past development, the implementation logic of Layer2 involved off-chain centralized computation processing of information, transmitting the results on-chain, which not only improved the computational efficiency of transactions but also fully utilized the high security performance of the ETH mainnet. The current mainstream implementation solutions of Layer2 include three types: Channel, Plasma, and Rollup. Since Rollup is essentially a further extension of the Plasma solution, possessing higher security, state validity, and data verification capabilities, Rollup has become the fundamental direction for the future development of Layer2.

There are two main branches in Rollup: Optimistic-Rollup and ZK-Rollup. In Optimistic-Rollup, it is assumed that the transaction results submitted to the main chain are optimistic. Under this assumption, there is no need to immediately verify each transaction, allowing for rapid submission and processing of transactions; a challenge period of about a week is set during which other validators can raise objections and submit corresponding evidence. If successful, the transaction will be rolled back, and the erroneous party will be penalized. On the other hand, ZK Rollup immediately verifies the correctness of transactions through zero-knowledge proofs, ensuring that transactions are almost 100% free of fraud. Overall, ZK-Rollup offers higher security compared to Optimistic-Rollup, with no delayed transaction confirmations during the challenge period, making it more promising for applications.

However, due to the technical implementation difficulty of ZK Rollup being much higher than that of Optimistic-Rollup, the mainstream market for Rollup technology is still occupied by Optimistic-Rollup. One trading platform currently leads in the Optimistic-Rollup sector, holding a 31.36% share of TVL, while another ZK-Rollup platform corresponds to only 1.32% of TVL. Because of this, how to create a standardized ZK-Rollup solution and gradually expand the ZK-Rollup application market has become an important issue. The comprehensive solution that Lumoz can provide may become the key to breaking the deadlock.

2. The Strong Background of Lumoz

Lumoz network is a globally distributed modular computing network that combines with DePIN network to create a powerful, secure, and flexible computing platform, providing computational support for ZK-Rollup, ZK ML, ZKP, and more. At the same time, Lumoz focuses on ZK-RaaS construction, aiming to provide a complete set of ZK Rollup deployment and implementation solutions to address various issues such as incompatibility of current ZK-Rollup solutions, centralized computing power, and concentrated risks.

Unlike the numerous concept projects that flood the Web3 space, Lumoz has been deeply engaged in the ZK field for many years. Its founder, Nanfeng, has held executive positions in several top technology companies and investment firms, possessing rich technical knowledge and outstanding blockchain project management capabilities. It is this cutting-edge thinking that has led him to lead the team into exploration and research in the ZK field since 2018.

The development history of Lumoz includes:

• Established in March 2022 in Hong Kong, committed to becoming a provider of blockchain scaling infrastructure.
• Completed a $4 million seed round financing in April 2023.
• Officially renamed to Lumoz in October 2023.
• Completed a $6 million Pre-Series A financing round in March 2024, with a valuation of up to $120 million.
• Strategic round financing completed in May 2024, with a valuation of up to 300 million USD.
• Whitelist node pre-sale starts in June 2024.
• The public sale of nodes will start in July 2024, in collaboration with a certain platform to hold a Launchpad event.

Lumoz launched its testnet in May 2023, and to date, it has 28,403 POW nodes, 16 allowed Rollups, 470,000 ZKP submissions, and 20 million transactions.

On the technical side, Lumoz has launched the ZK-Rollup Launchbase, increasing support for ETH, BSC, and the Polygon testnet, and providing various modular components such as Data Availability (DA) and shared sequencers. It has also achieved several groundbreaking inventions such as the ZKP Two-step Algorithm, NCRC, zkVerifier node verification mechanism, and the Lumoz RaaS Launchbase high compatibility technology stack. At the same time, it provides ZK computing support for other blockchain projects, with preliminary implementation of the technology.

3. Unified ZK Technical Solution

Lumoz provides a modular computing layer

Modular Rollup provides a new approach to solving the blockchain trilemma. Rollup generally achieves a layered structure by decomposing the blockchain system into different modules, resulting in more efficient transaction processing and data management, thus balancing the issues of decentralization, security, and scalability to some extent. Conventional Rollup typically includes a settlement layer, an execution layer, a consensus layer, and a data availability layer.

In addition to the four layers of conventional Rollup, Lumoz also includes the Prover Layer, which provides censorship-resistant distributed computation, implements ZKP, and ensures the authenticity and validity of transaction states.

ZK computing resources + EigenLayer re-staking dual narrative

Lumoz integrates powerful ZK computing resources with the EigenLayer restaking mechanism through Lumoz Oracle, zkProver, zkVerifier, and Lumoz Chain, allowing users to restake already staked tokens into EigenLayer. Lumoz will enhance the security of its Active Verification Service (AVS); at the same time, the staked tokens will serve as collateral for nodes, preventing malicious behavior from nodes.

This process allows multiple validation servers to share a set of tokens, thereby improving resource utilization and computational efficiency, which is extremely important for high computational demand ZKP generation; through re-staking, Lumoz can better support various EVM-compatible blockchain environments, such as Polygon EVM, Scroll, etc., increasing the platform's scalability.

Optimize ZKP calculation and submission mechanism

Lumoz optimizes the ZKP computation and submission mechanism, supporting parallel computation and sequential submission of ZKP, decomposing ZKP into multiple subtasks that can be computed on different zkProver nodes, and finally submitting the subtasks in the correct order.

In addition, Lumoz proposed a novel recursive aggregation algorithm for handling ZKP, which can aggregate multiple ZKPs into a smaller ZKP, reducing the size and complexity of ZKPs through a recursive approach, thereby lowering the consumption of blockchain storage and computing resources.

The aggregator serves as the core manager in zkProver, ensuring efficient allocation of computational tasks and precise scheduling of verifications.

the most compatible ZK-RaaS solution

The ZK-RaaS Launch Base now supports all mainstream zkEVM technologies, allowing developers to easily deploy and launch ZK-Rollups with just a few simple operations.

Specifically, Lumoz's ZK-RaaS platform supports multiple architectural models, including Modular Compute Layer, Native Cross-Rollup Communication, and Customizable Infrastructure Services. These features allow developers to choose different base layers, zkEVM types, data availability layers, and sorters according to their needs, enabling native cross-Rollup communication and customizing various infrastructure services.

It is precisely due to Lumoz's contributions that the deployment of ZK-Rollup will achieve a leap from difficulty to ease, which may signify the beginning of the trend of ZKP applications.

4. Token Model

The Lumoz token economic model is a typical dual-token governance model, providing two tokens: MOZ and esMOZ.

MOZ is the native token of the mainnet, serving as the core asset of the mainnet.

• MOZ can be used as gas fees for Lumoz mainnet transactions.
• The ZKP services and AI computing power services provided by Lumoz require payment in MOZ.
• MOZ can be exchanged for esMOZ at a 1:1 ratio.

esMOZ serves as an ecological governance token for the construction and maintenance of the mainnet ecosystem.

• Lumoz provides esMOZ as a reward to incentivize mainnet power providers and node operators.
• Users utilize esMOZ for online delegation to achieve decentralized governance.

It is worth mentioning that the exchange ratio of esMOZ to MOZ changes over time. With a 10-day redemption period, the redemption rate is 100%; with a 7-day redemption period, the redemption rate is 70%; with a 3-day redemption period, the redemption rate is 50%; and with a 1-day redemption period, the redemption rate is 10%. This redemption mechanism can alleviate the market pressure from miner tokens and effectively prevent large-scale redemptions of esMOZ after a hacker attack, thus protecting the rights and interests of MOZ purchasers.

5. The Development Prospects of Lumoz

As early as 2022, when Vitalik proposed that ZK-Rollup would be the best solution for Layer2 Rollups in the future, the vigorous development of ZK-Rollup was already destined.

The emergence of Lumoz will integrate the previously fragmented situations of ZK-Rollup, while optimizing the construction of ZK-Rollup and creating a complete set of easy deployment processes for ZK-Rollup.

• The Rollup revolution is imminent, and the emergence of Lumoz meets the urgent demand for integrating ZK-Rollup and driving industry updates.
• Lumoz provides a modular computing layer, combining EigenLayer with the staking concept to enhance the security and scalability of the mainnet.
• Lumoz optimizes the ZKP process, fully utilizing computing resources and improving computational efficiency.
• Lumoz provides a complete set of methods for deploying ZK-Rollup, which may open a new wave of ZK-Rollup project emergence.

Overall, the emergence of Lumoz will address the issues of high deployment difficulty of past ZK-Rollup, high computational resource requirements for ZKP, and the resulting centralization of computation, taking the most crucial step for the further development of ZK-Rollup in the future.
