Opside is a cutting-edge zkRollup-as-a-Service (ZK-RaaS) platform that enhances the performance, security, and scalability of decentralized applications (dApps) with its three-layered architecture and Zero-Knowledge (ZK) technology.

Opside

On October 12th, we are thrilled to that Opside has officially upgraded to Lumoz! This marks a significant step forward in Lumoz's development journey. At the same time, we also hope to take this opportunity to enable global users to better understand and apply ZK-Rollup technology, facilitate the large-scale implementation of zkEVM-based application chains, and further drive innovation in ZK technology. announce Lumoz (formerly Opside) officially launched its Testnet at the end of May this year and has been running smoothly for five months with continued strong participation from the global community. As of now, we have accumulated over 240,000 independent users, 25,000+ PoS Validators, and 100+ PoW miners. Additionally, more than 15 projects have passed official review and generated customized zkEVM application chains on Lumoz (formerly Opside) platform. Why Rebranding? Over the past year, Lumoz (formerly Opside) has achieved remarkable success. In the current landscape of RaaS (Rollup as a Service), Lumoz (formerly Opside) is the first and only platform dedicated to ZK-Rollup as a Service, providing underlying computational power. The name Opside originated from "Operator," but as Optimistic Rollup gradually gained more attention, we noticed that an increasing number of users incorrectly classified Opside as part of the Optimistic Rollup field. Furthermore, Opside has made steady progress in 2023, successfully launching the Pre-Alpha testnet, ZK-Rollup Launchbase, ZKP Two-step Algorithm, NCRC protocol, and other important user features. We have also established good communication and collaboration with numerous leading zkEVM projects, modular components, and third-party service providers within the ZK space, covering and involving a significant portion of the vertical direction in this field. In summary, the functionality and offerings provided by Opside can no longer be simply summarized by the term "Operator," and the original name may lead to unnecessary confusion. Therefore, we believe that comprehensive rebranding is necessary. Why Lumoz? After deciding on the rebranding, the team took prompt action and conducted multiple brainstorming sessions internally. We also sought advice from hundreds of community users and industry experts worldwide. As a result, the new name "Lumoz" was chosen. Lumoz is derived from the Latin word "Lumos," meaning "light" or "brightness." It draws inspiration from J.K. Rowling's bestselling novel series "Harry Potter," where "Lumos" is a spell used to illuminate the tip of a magic wand, creating light. By replacing the "s" with "z," "Lumoz" cleverly associates with "zk" (Zero-Knowledge) technology, forming a unique identifier. Additionally, for those familiar with Lumo, it resembles the orbital of a molecule, similar to an L2. We hope that Lumoz can become a beacon of light on the ZK track, illuminating the path for the widespread adoption of ZK-Rollup technology. Lumoz's Vision: Making ZK-Rollup Within Reach Since its inception in 2022, Lumoz (formerly Opside) has been committed to its mission of making ZK-Rollup technology more accessible and user-friendly. To achieve this, Lumoz (formerly Opside) was among the first in the industry to introduce the concept of ZK-RaaS (ZK-Rollup as a Service), catering to the needs of developers to create customized ZK-Rollup (zkEVM application chains) across multiple L1 networks. Over the course of more than a year since Lumoz (formerly Opside) was established, the team has remained persistent in overcoming challenges and achieving significant milestones. In May 2023, with the launch of the Pre-Alpha incentivized testnet, the functionality of one-click deployment of zkEVM application chains underwent successful small-scale testing. In August of the same year, Lumoz (formerly Opside) also made significant updates to the ZK-Rollup Launchbase, adding support for ETH/BSC/Polygon testnets as options for the Rollup L1 main chain and providing various modular components such as DA/shared sequencers. Today, an increasing number of developers/users are utilizing Lumoz (formerly Opside)'s no-code ZK-Rollup Launchbase to create customized zkEVM application chains. Additionally, during operation, Lumoz (formerly Opside) provides underlying computational power for general ZKP computations through the Decentralized Prover Network, allowing project teams to focus on subsequent operations. This significantly lowers the barriers to using ZK technology and reduces operational costs for project teams, while also effectively promoting the widespread adoption of ZK-Rollup technology. Towards the "Light," Lumoz has a bright future With this rebranding, it is evident to the world that Lumoz (formerly Opside) is determined to continue its long-term build in the direction of ZK-RaaS. Looking ahead, we will strictly adhere to the roadmap's plan: Currently, Lumoz (formerly Opside) supports zkEVM types such as Polygon zkEVM and zkSync, with plans to support Scroll, StarkNet, and others in Q4. By continuously expanding support for zkEVM types, Lumoz (formerly Opside) aims to meet the needs of different developers and projects, thereby promoting widespread adoption of ZK-Rollup technology. Supporting more zkEVM types: While the current ZK-Rollup Launchbase already meets the demands of most people, in our plans, these are just the basics. In the future, Lumoz (formerly Opside) plans to provide more modular components (such as integrating more third-party DAs) and functionalities to further simplify and accelerate the deployment of zkEVM application chains. Optimization of ZK-Rollup Launchbase: As of now, Lumoz (formerly Opside) has made significant progress in ecosystem development, with nearly a hundred ecosystem projects covering various domains such as GameFi, DeFi, NFT, Social, and Tool. In the future, we will actively seek opportunities to collaborate with more high-quality projects and strengthen innovative applications at the practical level, while sharing resources and traffic, effectively driving the adoption of ZK-Rollup technology. Continued expansion of ecosystem collaborations: With the gradual maturation of ZK-Rollup technology, there may be hundreds or even thousands of ZK-Rollups in the future, which will create a significant demand for ZKP computing power. Lumoz (formerly Opside) currently incentivizes miners to provide ZKP computing power through the ZK-PoW mechanism, thereby providing complete hardware infrastructure for ZK-Rollup. Therefore, miners will be an important component of the entire ecosystem. To that end, we have been actively adjusting the entry barriers for CPUs and GPUs. The ZKP two-step commitment algorithm proposed by our team has greatly improved the efficiency of ZKP generation. In the future, we will continue to make efforts at both the software and hardware levels to protect the rights and interests of miners to the maximum extent. Developing the miner ecosystem and lowering CPU & GPU entry barriers: While constantly seeking technological breakthroughs, we also aim to make more people aware of and utilize ZK-Rollup, pushing it to the forefront of wider applications. Therefore, in our future plans, Lumoz (formerly Opside) will not only participate in more industry summits/exchanges but also actively disseminate knowledge about ZK-Rollup to developers and users through hackathons, RaaS Days, and other means, providing support and guidance to better assist them in achieving innovation in their respective fields using ZK technology. Facilitating the popularization and promotion of ZK-Rollup technology: In Conclusion The potential of ZK-Rollup technology is unquestionable, and Lumoz (formerly Opside) firmly believes in it. Through this brand upgrade, we not only demonstrate our unwavering determination but also convey our mindset. We wholeheartedly invite all Web3 Builders to join the Lumoz (formerly Opside) network, witness this transformative journey, and become an integral part of the ZK-Rollup revolution. Currently, the Lumoz (formerly Opside) Testnet remains open, welcoming community users, developers, and industry enthusiasts who are interested in participating. By contributing their efforts, they have the opportunity to earn points, which can be exchanged for Lumoz (formerly Opside) Mainnet tokens upon its launch next year.

TL:DR Opside's NCRC (Native Cross Rollup Communication) protocol offers a trustless solution for Rollup interoperability. The NCRC protocol doesn't involve adding an additional third-party bridge to each Rollup; Instead, it transforms the native bridge of ZK-Rollup at the system level, allowing direct utilization of the native bridges of different ZK-Rollups for cross-Rollup communication. This approach is more streamlined and comprehensive, inheriting the absolute security of native bridges while avoiding the system complexity and trust costs associated with third-party bridges. has successfully implemented NCRC on the testnet. Anyone can now experience it on the official website at Opside https://pre-alpha-assetshub.opside.network/. Why Do We Need Trustless Cross Rollup Communication? Rollups have gained significant attention and adoption for their ability to enhance blockchain scalability, reduce transaction costs, and improve overall efficiency. Opside provides ZK-RaaS services for Web3 applications, enabling developers to create their own Rollups through the Opside Rollup Launchbase. In this era of multiple Rollups, we anticipate a growing coexistence of various Rollups, making seamless interoperability between different Layer 2 solutions crucial. Currently, interactions between Rollups remain relatively isolated, lacking real-time cross-chain communication and asset interoperability. This isolation has led to a fragmented landscape, where assets are confined within specific Rollups, restricting their free flow and utilization across different networks. The absence of efficient cross Rollup communication not only limits the potential of individual Rollups but also impacts the overall user experience. Users attempting to transfer assets or execute cross-chain transactions between Rollups face cumbersome and time-consuming processes. This suboptimal experience weakens the appeal of Rollups and to some extent hinders the widespread adoption of Layer 2 scaling solutions. Existing cross Rollup bridging solutions often involve deploying new sets of interchain contracts on Rollup chains and utilizing multi-chain liquidity incentives to achieve asset cross-chain functionality. However, these solutions are not universally applicable for message-based cross-chain interactions and come with risks of centralization and trust. To fully unlock the potential of the multi Rollup era, there is an urgent need for a trustless and universal cross Rollup communication protocol. Opside's solution: Native Cross Rollup Communication In fact, each ZK-Rollup comes with an L1<>L2 bridge inherently, which we refer to as the Native bridge. Unlike third-party bridges that utilize liquidity-based schemes, the Native bridge operates as the unique "mint-burn" cross-chain mechanism. It ensures security through zero-knowledge proofs while maintaining trustlessness. All assets on a Rollup originate from deposit transactions through the native bridge and receive ultimate security endorsement from it. We firmly believe in the principle of Occam's Razor – "Entities are not to be multiplied beyond necessity." Third-party bridges may offer cheaper and faster cross-chain experiences, but they introduce additional trust costs and security risks. The recent Multichain incident is a case in point. Therefore, from the outset, Opside's inspiration for cross-Rollup communication was straightforward: leverage the native bridge directly to achieve multi-Rollup interoperability, rather than introducing an additional third-party bridge. This concept gave birth to the NCRC (Native Cross Rollup Communication) protocol. Prerequisites for NCRC To enable NCRC among multiple Rollups, the following two prerequisites need to be met: These Rollups must belong to the ZK-Rollup type. These Rollups must reside on the same L1. Rollups satisfying these two conditions theoretically possess the same level of security as the underlying L1. Similarly, the security level of the native bridge among these Rollups is identical and requires no trust between them. All NCRC transactions are verified by validity proofs, serving as the fundamental source of security assurance for NCRC. Rollup Recognition Contract（RRC） As of August 2023, several ZK-Rollups have gone live on the Mainnet, including Polygon zkEVM, zkSync era, Linea, and more. However, these ZK-Rollups are independent and unrelated, leading to the fragmentation of user assets. The fundamental reason for this issue lies in the fact that their contracts on L1 (Ethereum Mainnet) are unrelated. They remain unaware of each other's existence and are unable to directly communicate through native Rollup bridges. Therefore, the first step we need to take is deploying a specialized contract on L1 to enable Rollups to discover and recognize each other. This is referred to as the RRC (Rollup Recognition Contract). The RRC is responsible for managing all participating ZK-Rollups in the NCRC, including additions, pauses, and exits of Rollups. Each Rollup within the RRC is assigned a dedicated Rollup ID, while the ID for L1 remains fixed at 0. When initiating cross-Rollup transactions through the native bridge on a Rollup, addresses can specify the target Rollup ID: If the Rollup ID is 0, it signifies crossing the message to L1, such as withdrawal. If the Rollup ID is not 0, it indicates sending the message to another Rollup. Opside will deploy an RRC contract on every L1 layer and allow corresponding ZK-Rollups to join or exit without permission. This RRC contract will be used to maintain information for each Rollup ID, including the bridge contract address on L1. It's important to note that the RRC contract solely provides data retrieval services and does not directly interact with cross-chain assets. Compatibility with Native Bridge Smart Contracts and Services Generally, Rollup's native bridge is divided into three components: the bridge contract on L1, the bridge contract on L2, and a bridge service responsible for message relay. The NCRC protocol leverages these components at the underlying level and adds higher-level encapsulation. The main modifications are as follows: Bridge contract on L2: While preserving the original methods, a new method named bridgeAsset is added. This method allows users to specify the target Rollup's ID in the destinationNetwork parameter. Bridge contract on L1: A new method is encapsulated to handle the cross-chain messages of the new bridgeAsset method. The bridge contract, based on the Rollup ID found in the RRC contract, locates the information of the target Rollup and transfers the cross-chain assets to the bridge contract of the target Rollup. The cross-chain assets are deposited into the target Rollup there. Bridge service: Responsible for message relay and charges users fees for cross-Rollup transactions. Once a Rollup completes the NCRC-related compatibility adaptation mentioned above, it can register with the RRC to join the native cross-Rollup communication network. Process of Native Cross-Rollup Transactions For users, the operation of NCRC is entirely consistent with that of Rollup's native bridge. Initiating a cross-Rollup transaction from Rollup1 to Rollup2 is an automated process, including the following steps: The initiator, User1, on Rollup1, invokes the bridgeAsset method of the native bridge to initiate the cross-chain transaction. The destinationNetwork parameter in this transaction is set to the Rollup ID of Rollup2. This Rollup ID will be used to retrieve the corresponding L1 bridge contract address. If the Rollup ID is 0, it signifies the target network as L1. Subsequently, this transaction is packaged by Sequencer1 of Rollup1. The initiator, User1, bears the cost of the cross-Rollup transaction, paying it to Sequencer1 on Rollup1. Rollup1's Bridge service then transfers the cross-chain asset to the Rollup1 bridge contract on L1. At this point, both Rollup1 and L1 complete the burn and release operations of the asset. To complete the cross-Rollup asset transfer, Rollup1's Bridge service queries the RRC contract to retrieve information about the target Rollup2 corresponding to the destinationNetwork parameter. This information provides the L1 bridge contract address of Rollup2. Then, the bridge contract of Rollup2 takes control of these assets and maps them to Rollup2 through the bridgeAsset method. Finally, once the transaction is successfully packaged and the proof is generated, Rollup2's Bridge service executes the claimAsset operation. Consequently, the cross-chain assets initiated by Rollup1 safely arrive at the designated address on Rollup2. It's worth mentioning that throughout the cross-chain process, the user's assets flow through the following path: Rollup1 -> Rollup1's L1 bridge contract -> Rollup2's L1 bridge contract -> Rollup2. In other words, the user's assets do not go through any third-party protocol; they leverage Rollup's native bridge. The entire process is secure and trustless. When users execute cross-chain operations on Rollup1, selecting Rollup2 as the destination, the technical process actually involves three entities: Rollup1, L1, and Rollup2. However, users do not need to be aware of the existence of L1 in this process; their experience is simply a direct cross from Rollup1 to Rollup2. The underlying reality is that cross-chain assets undergo two bridging operations on L1, creating a seamless connection from Rollup1 to Rollup2 in the user's perception. During this process, operations on L1 are handled automatically, and users do not need to perform any additional actions. From the user's perspective, their current Rollup can perform cross-chain operations to both L1 and any other Rollup. This design enhances user experience fluidity while concealing underlying complexities. NCRC is now live on the Opside testnet! Opside has successfully implemented native cross-rollup communication on the Testnet. Anyone can now experience it on the official website at .We also welcome users and developers to help us identify potential bugs and security risks and provide any valuable suggestions. https://pre-alpha-assetshub.opside.network/ We believe that trustless native cross-rollup communication will not only securely share liquidity across all Rollups but also provide robust multi-Rollup interoperability, opening up new possibilities for decentralized applications and .

RaaS (Rollup as a Service) has been hailed as one of the most promising tracks within the Rollup ecosystem. However, the market's preference between an early and evolving OP Stack or the rapidly advancing ZK Stack, which holds great potential, remains to be seen. As one of the contributors to the ZK ecosystem, Opside has recently shared some exciting news. On August 14th, the decentralized ZK-RaaS platform, Opside, announced a major update to its . This update supports developers in building custom zkEVM application chains. ZK-Rollup LaunchBase Core ZK-Rollup components, including Layer1, zkEVM, Gas, DA (Data Availability), and Sequencer, are now open for customization. Moreover, this version of ZK-Rollup LaunchBase also offers various  IaaS (Infra as a Service) for initial project selections. This marks a significant achievement for Opside in terms of modular and customizable Rollup development. It empowers developers and projects to construct customized zkEVM application chains flexibly, fostering expansion and empowerment within the entire ZK ecosystem. Highlight 1: Support for More L1 Options Such as ETH/BSC/Polygon The choice of Layer1, the foundation for Layer2 network building, is crucial since all user transactions eventually return to Layer1. In the early design stages of Opside, catering to developers' needs for different EVM-compatible base networks was a priority. The latest LaunchBase by Opside now supports additional testing options like ETH/BSC/Polygon. Developers can choose ETH Goerli, Polygon Mumbai, BNB Testnet Opside, or Opside as the base network when creating an L2. After a series of stress tests on the testnet, the support for ETH/BNB Chain/Polygon mainnets is expected to be available in early September. Clearly, modularity not only enables developers to choose different Layer1 options but also provides diversity and flexibility for other components like zkEVM and Gas Fee Token choices. Opside now fully supports Polygon zkEVM and is actively expanding support for zkSync, Scroll, StartNet, and other zkEVM types such as Linea and Takiko. Additionally, the Gas Fee Token selection is more diverse, allowing project teams or developers to customize tokens for ZK-Rollup's Gas Fee Token. Prior to this, over 12 prominent projects in various industries have generated customized zkEVM application chains through Opside LaunchBase. These projects span Defi, Socialfi, and Gamefi applications. For example, ReadOn, a renowned content distribution platform, generated its own ZK-Rollup, bridge, and browser within 10 minutes using Opside Rollup Launchbase. They also employed their Native Token as ZK-Rollup's Gas Fee Token. Similarly, Era7, once among the top three gaming projects on the BNB Chain, created a dedicated zkEVM application chain using Opside Rollup Launchbase. Notably, they used Opside's 0 gas fee feature in specific contracts, allowing users to interact with contracts without any fees, thus lowering entry barriers for traditional Web2 gamers. Moreover, over 20 projects are currently under active discussion and promotion with the Opside team. Opside anticipates more projects will adopt ZK-Rollup technology, reducing operational costs while ensuring security and enhancing user experiences. Highlight 2: Multiple Data Availability (DA) and Shared Sequencer Components DA and shared sequencers are essential for customizing ZK-Rollups. Opside provides a variety of DA components for developers to choose from. DA options within Opside ZK-RaaS LaunchBase include Base Layer (already supported), Opside DA (PoS), and third-party DAs (e.g., Celestia, Eigenlayer), catering to different project requirements. Shared sequencers are essentially a set of sequencers compatible with Rollups, serving different Rollups. However, all second-layer Rollups on Ethereum currently use centralized sequencers. Opside's vision includes offering three sequencer options: centralized (already supported), Opside's decentralized Sequencer (PoS), and third-party decentralized Sequencers (Espresso, Radius). This ensures developers enjoy flexibility while maintaining the security of the entire application chain. Highlight 3: Multiple Infra as a Service Options Alongside various customization features, Opside's ZK-Rollup LaunchBase also provides multiple Infra as a Service options for initial project selections. After generating a dedicated zkEVM application chain, infrastructure demands arise on-chain. For instance, Defi applications may require oracles and other foundational components. Opside has collaborated with well-known infrastructure providers and projects within the industry to offer a range of Infra as a Service options. These options include, but are not limited to, Wallet as a Service, Dex as a Service, Oracle as a Service, NFT Market as a Service, and DID as a Service. Options encompass OKX Web3 Wallet, iZUMi, Star protocol, Space ID, and Supraoracle, among others, with ongoing negotiations for further inclusion. More projects interested in the Opside ZK ecosystem and Infra as a Service are welcome to engage in deeper communication with the Opside team at . Let's collaborate to create a thriving ZK ecosystem!

Opside is a decentralized ZK-RaaS ( as a Service) platform and a PoW network that supports ZKP (Zero-Knowledge Proof) mining. Opside uses a hybrid PoS & PoW consensus and provides a one-click feature for Web3 developers to create zkEVM application chains. At the same time, the massive computational tasks brought by many ZK-Rollups have generated a huge demand for computational power, providing a meaningful mining scenario for miners around the world. ZK-Rollup Opside's mission is to make ZK-Rollup more user-friendly and popular, thereby enabling the widespread implementation of application chains based on zkEVM. Opside provides the following services and innovations: ZK-Rollup as a Service: For developers, they can deploy their own ZK-Rollup (zkEVM) on multiple chains with one click. Opside ZK-PoW Cloud: For miners, Opside is also a multi-chain PoW protocol, supporting ZK mining, and generating zero-knowledge proofs for ZK-Rollups on multiple public chains. Advantages of Opside According to Vitalik's latest article, we will transition from a multi-chain era to a multi-Rollup era in the future. The ZK-Rollup as a Service provided by Opside will make it possible for ZK-Rollup to be widely used. Developers do not need any ZK knowledge, they can create their own ZK-Rollup by selecting through the front-end interface. The created ZK-Rollup can become the Layer 2 of any public chain (such as Ethereum, BNB Chain, or Polygon PoS). The computational power involved will also be provided by the Opside ZK-PoW multi-chain protocol. This greatly reduces the development and operational costs of the project. In addition, Opside will launch specific contracts with 0 gas fees in early July. When users use certain dApps on some custom ZK-Rollup, they will not have to pay any gas fees. These 0 gas fee contracts aim to solve the current high entry barriers of Web3 dApps and greatly improve the user experience.

Decentralization: Utilizing ETH 2.0's PoS consensus, Opside enables more extensive validation and miner participation, enhancing security. The Potential of Opside More and more developers and project owners have demands for sovereign ZK-Rollup and 0 gas fee. Project owners can generate sovereign ZK-Rollups via Opside's official rollup launchbase in 10 minutes, along with setting up basic matching settings such as browsers and bridges. Sovereign ZK-Rollup means higher security and stability. The 0 gas fee reduces user entry barriers, allowing many Web2 traffic to enter Web3 without obstacles. After transitioning from ETH to PoS, many miners have no place to go. Opside's multi-chain ZKP PoW protocol can connect any rollup, providing them with decentralized computing power to generate ZK proofs. Opside maintains good relationships with global miners like Ingoyama and others, with joint promotions already underway. At present, Opside is still in the early stage. It has been more than a month since the testnet was launched, and it already has over 12k validators, over 60 large miners, and more than 120k independent user addresses. A large-scale increase in various data is expected in the future. Conclusion & Outlook As a decentralized ZK-RaaS platform and a PoW network that supports ZKP mining, Opside has accelerated the widespread implementation of application chains based on zkEVM. Opside not only provides a one-click ZK-Rollup application chain generation feature, reducing the technical burden for developers, but it also uses its ZK-PoW Cloud to meet the computational demands of ZKP tasks generated by the increase in ZK-Rollups, creating a new mining scenario for global miners. Moreover, Opside's 0 gas fee contract greatly enhances user experience and reduces entry barriers, which is of epoch-making significance in solving the current high entry threshold of Web3 dApps. Since the launch of the Opside Pre-alpha Testnet on May 24, 2023, it has gained widespread attention and positive feedback globally. With the continuous advancement and development of Rollup, there is reason to expect that ZK-Rollup technology will become more prevalent in many application scenarios. The emergence and development of Opside have made the large-scale implementation of ZK-Rollup possible. Also, it provides new mining opportunities for miners. Opside maintains a good cooperative relationship with large miners globally, laying a solid foundation for Opside's future development.

Opside ZK-PoW Introduction Opside is a decentralized ZK-RaaS (ZK-Rollup as a Service) platform and a leading network for ZKP (Zero-Knowledge Proof) mining. ZK-RaaS provides a one-click service for generating ZK-Rollups to anyone. Opside offers a universal ZK-Rollup launchbase, allowing developers to easily deploy different types of ZK-Rollups on various base chains. Base chains: Ethereum/Opside chain/BNB chain/Polygon PoS, and other public chains. ZK-Rollup types: zkSync, Polygon zkEVM, Scroll, StarkNet, and other variants of ZK-Rollups. In Opside's design, developers can deploy ZK-Rollups on these different base chains. As ZK-Rollup technology matures, there may be hundreds or even thousands of ZK-Rollups in the future, which will create a significant demand for ZKP computation power. Opside utilizes the ZK-PoW mechanism to incentivize miners to provide ZKP computation power, thus providing a complete hardware infrastructure for ZK-Rollups. ZK-PoW V2.0 Architecture The overall architecture of ZK-PoW V2.0 consists of several key components: This is the cloud infrastructure provided by Opside for ZKP computation. It is deployed across multiple chains, including Ethereum, BNB Chain, Polygon PoS, and Opside Chain. The ZK-PoW Cloud is responsible for coordinating and managing the ZKP computation tasks. ZK-PoW Cloud: These are the nodes operated by miners who contribute their computational power to perform ZKP computations. Miners can participate in the ZK-PoW network by running specialized software on their mining hardware. Miner Nodes: The ZK-PoW Cloud distributes ZKP computation tasks to the miner nodes. The distribution is done in a decentralized manner to ensure fairness and efficiency. The ZKP tasks include generating and verifying zero-knowledge proofs for various ZK-Rollups. ZKP Task Distribution: The miner nodes receive ZKP computation tasks and perform the necessary computations to generate the required proofs. This involves executing cryptographic algorithms and performing complex calculations. ZKP Computation: Once the ZKP computations are completed, the miner nodes submit the generated proofs to the ZK-PoW Cloud for verification. The cloud infrastructure verifies the correctness of the proofs to ensure their validity and integrity. Proof Submission and Verification: Miners are incentivized to participate in the ZK-PoW network by earning rewards for their computational contributions. The reward system is designed to motivate miners and maintain the security and stability of the network. Incentive Mechanism: Overall, ZK-PoW V2.0 combines the power of miners' computational resources with cloud infrastructure to provide efficient and scalable ZKP computation for a wide range of ZK-Rollups. The Aggregator is an important component of the Prover in the ZK-PoW V2.0 system. It is responsible for distributing ZKP proof tasks, receiving task results (ZKP proofs), managing the proofs, and submitting them to the Base Chain to earn rewards. Based on their functions, the new version of the Aggregator is divided into three sub-modules: Proof Generator, Proof Manager, and Proof Sender. The Proof Generator module is responsible for assigning proof tasks to the Prover (PoW miner), receiving the task results (ZKP proofs), and storing the ZKP proofs in the DB database. The Proof Manager is in charge of managing the completed ZKP proofs and packaging the proofs that are ready for on-chain submission as tasks for the Proof Sender module. The Proof Sender module handles the on-chain submission of ZKP proofs by submitting them to the zkEVM contract deployed on the Base Chain. Below are the introductions of these three modules: Proof generator Rollup Chain aggregates a certain number of transactions into a batch, and then multiple batches (based on factors such as transaction frequency) are combined into a sequence. The sequence is then submitted to the Base Chain, making it the unit of data submission for each on-chain operation. Each sequence consists of one or more batches, and the ZKP proof verifies the validity of the submitted sequence. Therefore, the batch is the smallest unit of proof task. Depending on the number of batches included in a sequence, the required proof tasks vary as follows: If the number of batches is 1, the proof process involves BatchProofTask followed by FinalProofTask, and the tasks are completed sequentially. If the sequence contains more than 1 batch, the proof process involves multiple BatchProofTasks, an AggregatorProofTask, and a FinalProofTask, and the tasks are completed sequentially. To maximize the efficiency of proof generation and increase the mining rewards for PoW miners, we aim to generate proofs concurrently. This is achieved in two aspects: Proof generation for different sequences can be done concurrently as there is no contextual or state dependency. Within the same sequence, multiple BatchProofTasks can be executed concurrently. This approach utilizes the computational resources of Provers more efficiently, resulting in more efficient proof generation. Proof manager This module is primarily responsible for managing ZKP proofs and controlling their on-chain verification. It consists of three main modules: : This module is executed only once when the Aggregator starts. Its purpose is to complete the submission of unfinished ZKP proofs from the previous Aggregator service. This handles the situation where proofHash has been submitted but other miners have already submitted their proofs. For more information about proofHash, please refer to the Proof Sender module. submitPendingProof : This module runs as a coroutine and adds the latest generated ZKP proof, along with its corresponding unverified sequence, to the Proof Sender's cache, waiting for on-chain submission. tryFetchProofToSend : This module runs as a coroutine and aims to resubmit sequences that have not been successfully verified within a given time window. Its purpose is to ensure that sequences that exceed the verification time are resubmitted for on-chain processing. processResend Proof sender has proposed a two-step ZKP submission algorithm to achieve decentralization of the prover. This algorithm prevents ZKP front-running attacks and enables more miners to receive rewards, thereby encouraging more miners to participate and provide stable and continuous ZKP computation power. Opside : When producing a PoW proof for a specific sequence (referred to as proof), the prover first calculates the hash of "proof / address" and submits it to the contract. If no proofHash has been submitted for that sequence before, a proofHash submission time window, T1, is opened. Miners are eligible to submit the sequence within T1 blocks, and proof can only be submitted after T1 blocks. Step 1 : After T1 blocks, the proof submission window is opened for T2 blocks. If none of the submitted proofs pass the verification within T2 blocks, all miners who previously submitted proofHash will be penalized. If proofHash is successfully submitted within the T1 time window but proof cannot be successfully submitted within the T2 time window, and other miners successfully submit their proofs within T2 window, the prover can still continue to submit that proof. In other scenarios, the two-step submission process is restarted. Step 2 The following diagram illustrates how Proof Sender implements the two-step submission using three thread-safe and priority-sorted caches. These caches are sorted based on the starting height of the sequences, ensuring that each time an element is retrieved from these caches, it corresponds to the lowest sequence height. Additionally, the elements in these caches are deduplicated. The lower the height of the corresponding sequence, the higher the priority for processing. finalProofMsgCache: Stores the finalProof messages sent by the Proof Manager, indicating the completion of ZKP proofs. monitPHTxCache: Stores the proofHash transactions to be monitored. ProofHashCache: Stores the proof messages for on-chain submission. After the Proof Sender module is launched, three coroutines are started to consume data from the three caches. The simplified process is as follows: Coroutine 1 consumes the finalProof messages from the finalProofMsgCache, calculates the proofHash, and if it meets the conditions for on-chain submission (within the T1 window), it submits the proofHash to the chain and adds the proofHash transaction to the monitPHTxCache. Coroutine 2 consumes the proofHash transaction messages from the monitPHTxCache. If the proofHash meets the conditions for on-chain submission within the T2 window, it constructs the proof message and stores it in the ProofHashCache. Coroutine 3 consumes the proof messages from the ProofHashCache and submits the proofs to the chain. Compared to the previous module, this structure is clearer and saves on resource overhead. Summary Comparison with Version 1.0 Version 2.0 splits the original service into three sub-modules, each responsible for proof generation, proof management, and proof submission, resulting in a clearer structure, lower coupling, and stronger robustness. The proof generation module, Proof Generator, has added the startBatch parameter compared to the old version, making it easier for new miners to catch up with the mining progress. The proof management module, Proof Manager, has been improved compared to the old version. It promptly resends proofs in case of miner service restart or other reasons for proof submission failure, ensuring miner interests. The resend mechanism not only addresses proof submission failure cases but also handles all cases of proof submission failure or non-submission, ensuring the security of the Rollup Chain. The proof submission module, Proof Sender, implements a two-step transaction submission using three thread-safe priority caches. It reduces the use of global locks compared to previous versions, ensuring that proofs with lower heights are submitted promptly and protecting miner interests. Additionally, the overall service flow is clearer, with reduced thread count and reduced resource consumption during program execution. Stress testing results: In Version 2.0, using 10 machines with 64 cores each, 566 batch proofs were completed in 7 hours, 38 minutes, and 40 seconds, with an average time of 48.62 seconds per proof. In a multi-miner scenario, compared to Version 1.0, the efficiency of zk proof generation in Version 2.0 improved by 50% overall. In conclusion, Opside ZK-PoW V2.0 has optimized the process of multiple miners participating in ZKP computations, improving hardware utilization, enhancing service availability, and being more miner-friendly. Importantly, in a multi-miner scenario, the computation time for ZKP has been reduced to less than a minute, significantly accelerating the confirmation time of ZK-Rollup transactions.

The Opside community has always placed a heavy emphasis on Proof of Stake (PoS) nodes. Since the inception of the Opside Pre-alpha Testnet on May 24, there has been a significant uptick in the number of official Opside validators. Currently, there are more than 10,000 validators, operating stably and providing a robust infrastructure for the Opside network. Taking into account the operational cost per node—over $1,500 per annum as priced by Amazon, Google Cloud, and similar service providers— the community's total investment in the Opside network has neared an impressive $15 million. About half a month ago, the official cold-start validators voluntarily withdrew, marking a significant milestone for Opside. The network, now fully decentralized, is upheld by community-operated nodes. These nodes, amounting to over 10,000, span across 41 countries and are situated in 301 cities, highlighting the truly global and decentralized nature of the Opside network. Over the past month, the official team at Opside has rolled out several key updates and modifications to the PoS nodes. These updates encompass: Iterative software updates from V1 to V3, enhancing the user interface and overall experience. The initiation of a batch pledge function on the official website, enabling streamlined operations. The capability for a single node to generate and manage multiple Validator functions. Incremental updates to the Consensus beacon browser. Opside Pre-alpha Testnet has maintained a stable run for more than a month now. To foster greater community involvement in PoS and to ensure the continued security and stability of Opside, the team has compiled a list of frequently asked questions (FAQs) pertaining to PoS node construction and operation based on the past month's experiences. These FAQs have been categorized into basic and advanced sections for convenience. Basic Level Q&A: 1. A Brief Overview of Opside PoS Validator? Opside Chain employs the PoS consensus, which is an enhanced version of the one used by ETH 2.0. Validators are crucial for maintaining network-wide security and stability. To qualify as a Validator, users must deposit a designated amount of IDE into the deposit contract and operate three independent software tools: the execution client, consensus client, and validator. Validators bear the responsibility of validating new blocks propagated across the network, and intermittently, they create and propagate new blocks themselves. If any Validator engages in dishonest behavior, the pledged IDE will be penalized and destroyed. This PoS approach encourages individual participation in network protection and promotes decentralization. 2. What Are the Advantages of Participating in Opside PoS and Becoming a Validator? Validators contribute to the smooth operation and future development of the Opside network. As a reward, they receive block rewards in the form of IDE, which can be exchanged for points at a predetermined ratio. These points can then be swapped for Opside mainnet Tokens in the future. 3. How Do You Become a Validator? Here are a few simple steps to becoming a Validator: Ensure you have a server that fulfills the following specifications: OS: 64-bit Linux, Mac OS X 10.14+, Windows 10+ 64-bit CPU: 4+ cores @ 2.8+ GHz Memory: 16GB+ RAM Storage: SSD with at least 500GB free space (2TB recommended for mainnet) The above configuration is recommended by the official team, and users can run PoS nodes with machines of lower performance. However, machines with too low performance may lead to disconnection or slow synchronization, which could ultimately result in slashing from the network. Note: Maintain a stable network connection. Run the execution client, consensus client, and Validator as three independent software programs on the server. Stake 25,000 IDE via the Opside front-end interface and wait for 16-24 hours for data synchronization. Check the operational status of the node at https://opside.network/validator/overview . Congratulations, you're now officially an Opside-certified validator! Text Guide: https://docs.opside.network/validators-pos/run-a-validator Video Tutorial: 4. How Can You Acquire Testnet IDE? Generally, there are three ways to get testnet IDE: Apply to become an official validator. The application standards have been progressively relaxed, and the PoS whitelist is updated weekly. APPLY NOW: https://forms.gle/cCVB3iAsXEVBW8sm6 Use other tokens like GETH to swap in the IDE liquidity pool of the existing decentralized exchange.
