# Vision **Scaling Bitcoin without compromise, other than that, there's so much more we can do** ## Vision 1. We progress toward bringing general purpose computation to Bitcoin inscriptions. 2. We are committed to creating a universal state machine platform based on the paradigm of the Virtual Machine built on Inscriptions, which targets to traditional Apps. ## Rationale #### **Section Ⅰ** Inscriptions such as [Ordinals](https://docs.ordinals.com/), [Atomicals,](https://docs.atomicals.xyz/) etc, were designed to model the creation, ownership, and transfer of non-fungible digital artifacts. Despite the tremendous potential this functionality shows, it is fundamentally limited. It is not surprising that we can always hear the constant request from the communities over the world: "Make inscriptions/Ordinals do more things!" Undoubtedly, we can add new functionality to inscriptions by reinterpreting the inscriptions themselves. For example, as in the BRC-20 standard on Bitcoin, a properly-formatted Ordinals inscription could represent not a digital artifact to be held or transferred, but rather a one-time command like "deploy this new token!" or “deposit token”. Actually, we have seen some of popular platforms, for instance, [Unisat](https://unisat.io/), are experimentally coming out more complicated features on this way. An even more inspiring example here is that [ESIP-4](https://docs.ethscriptions.com/esips/out-of-date-esip-4-the-ethscriptions-virtual-machine) introduces the Ethscriptions Virtual Machine (ESC VM), a new protocol built on top of Ethscriptions. The ESC VM enhances the functionality of the Ethscriptions Protocol by enabling ethscriptions to function as computer commands in addition to digital artifacts. These computer commands allow users to interact with special computer programs called Dumb Contracts. The ESC VM provides Dumb Contracts with an environment similar to the EVM, enabling Dumb Contract functionality to parallel that of Smart Contracts. However, since Bitcoin natively does not support smart contracts, equipping Bitcoin's native network with such a computing platform is particularly important. Furthermore, implementing computation and storage in this manner would be significantly cheaper compared to the existing smart contracts currently running on Ethereum. This argument has also been confirmed in the ESC VM proposal. Similar to the goal of ESC VM in Ethereum, the purpose of the 0xVM is to enhance the functionality and scope of the Ordinals Protocol by enabling it to function as a general computation engine. Users access the 0xVM by creating special inscriptions that the 0xVM interprets as computer commands to the protocol defined. 0xVM is neither a blockchain nor a Layer 2 solution. It represents a new path of exploration for scaling Bitcoin. The most enticing blueprint is we progress toward bringing general purpose computation to inscriptions, which increases the possibility of introducing a wider range of application scenarios within the Bitcoin ecosystem. We pay tribute to[ Facet](https://docs.facet.org/) and [Ethscriptions](https://docs.ethscriptions.com/overview/introducing-ethscriptions), as they have conducted much exploration ahead of us. However, during our own experiments over the past two months, we have realized the challenges of implementing our vision on Bitcoin due to the different technical architectures of Bitcoin and Ethereum. Nevertheless, we have found corresponding solutions to these challenges. What's even more exciting is that we have every reason to believe that the superiority of UTXO makes the future of 0xVM even brighter. #### **Section Ⅱ** In application development, regardless of scale, the maintenance of state machines is a fundamental and critical task. State machines simplify the design and implementation of complex workflows, which can help reduce complexity and improve maintainability. Yet, most enterprises continue to allocate considerable engineering efforts to this sector, due to the inherent challenges in designing and maintaining state machines. The complexity escalates especially when dealing with intricate logic, making robustness harder to achieve. Take inscriptions, for instance. Asset management leans heavily on indexers, essentially serving as off-chain ledgers. Their implementation complexity is palpable, like needing to index and trace all UTXOs, involving lengthy and intricate logical sequences. Any error in this chain can compromise the entire ledger. A well-crafted state machine for ledger management could significantly simplify these operations, considering several approaches: 1. RDBMS-Based State Machine Applications This approach involves building the state machine's architecture and components from the ground up, demanding significant effort and often resulting in lower stability due to the need for independent management of the state machine's intricacies. 2. Ethereum/L2-Based DApps Ethereum is essentially a transaction-based state machine, transiting from an initial state to a current one through transactions. Here, Ethereum functions as the state database, with new states continually written via smart contract calls. The relational database records only the outcomes of these executions, forming the backbone of the state machine applications. Ethereum handles the intricate aspects of state machine management – security, consistency, etc., leaving users to focus on specific programming logic. However, this method incurs substantial costs and faces issues like low TPS and complex asynchronous cache management due to the inherent blockchain nature. The concept of using Ethereum's Layer 2 as an alternative faces similar limitations due to its reliance on blocks and P2P networks. Despite its allure in addressing cost and TPS issues, it still entails complex asynchronous cache management on user-end. Based on the logic in the Section Ⅰ, the inscription-based VM points to a new direction: the EVM can be used for off-chain computation, such as in traditional backends, and it enables transactions to be instantaneous. Deploying a smart contract on such platforms grants users a streamlined, robust state machine service. This method simplifies the state machine implementation – it's straightforward, secure, and each component has a clear, defined role. For example, implementing a Mint Asset entitled process in such an environment is incredibly efficient, requiring minimal coding and no in-depth understanding of Mint's internal workings. For enterprises, there is no need to understand the internal logic of Mint, simply capturing the successful event and recording it in a RDBMS builds the application of this complex state machine. We are convinced that this is a groundbreaking advancement. Imagine the substantial resources and workforce required by PayPal, as well as other banks and financial institutions, to effectively manage their ledgers. Should PayPal decide to build its asset management system utilizing smart contracts for logical workflows on an off-chain inscription-based VM, it's conceivable that about 60% of their backend engineers might become redundant. Such a transformative approach could fundamentally alter the way financial ledgers are managed and maintained, offering a more efficient and streamlined process. # Efficient Scaling When discussing how to scale up a blockchain network, the efficiency of this scaling is a crucial factor that must be considered. Scaling must not only increase the network's capacity but also do so in a way that maintains or improves overall performance and security. [Facet](https://docs.facet.org/) argues that it optimizes the way transactions and smart contracts are handled, aiming to eliminate the need for and costs associated with executing smart contracts directly on the blockchain. Following this point of view, here’s a breakdown of what we are considering: 1. **Rethinking Smart Contracts**: 0xVM challenges the conventional belief in blockchain sector that smart contracts are indispensable. While smart contracts are a defining feature of classic blockchain system, 0xVM posits that they are also a significant source of inefficiency and high costs. 2. **Predicting Smart Contract Outcomes**: The key idea is that if the outcome of a smart contract can be predicted with certainty, there’s no need to execute the contract on the blockchain, incurring the associated costs. Instead, these predictable outcomes can be used directly. 3. **Cost Efficiency in Prediction vs. Execution**: Simulating or predicting the behavior of a smart contract is much cheaper than executing the contract on blockchain, like Ethereum’s protocol. This difference in cost is due to the fact that executing smart contract logic requires network validators, which involves a consensus process and computational resources. In contrast, simulating a smart contract’s behavior can be done by anyone without needing to engage the blockchain's consensus mechanism and computational resources. 4. **Challenges and Potential**: While this approach is promising in theory, it presents challenges in ensuring the accuracy and trustworthiness of these predictions. There’s also the need to maintain security and consensus, which are core to the blockchain network. The successful implementation of 0xVM’s concept would require careful consideration of these factors to maintain the integrity and reliability of the network. In summary, 0xVM’s goal is to develop a system where everyone can simulate smart contract behavior, and these simulations can replace the actual execution of smart contracts on Bitcoin blockchain. This approach could significantly reduce the costs associated with smart contracts by avoiding the need for blockchain execution in predictable scenarios. *Learn More：* 1.

[Predictions to Protocol](https://docs.facet.org/what-is-facet/predictions-to-protocol) # Fun Facts of Heterogeneous Computing Deeply engaged in our lab's explorative environment, we have thoroughly researched on the use of GPUs and computational chips for diversely running smart contracts. Our setup, which included a pair of 3090, consumer-level GPU , remarkably achieved the feat of 200 million smart contract calls within a mere second. Amid the DeFi summer buzz, we conducted a series of intriguing experiments. One notable venture was harnessing CUDA technology to process 200 million paths every second, enabling lucrative arbitrage across various swaps. Our approach focused primarily on the liquidity pools present in these swaps, bypassing subjective trading strategies. We identified a myriad of potential paths across thousands of these pools, with simple ones like USDT->BTC->USDT. Our objective was to rapidly enumerate about 200 million paths, a task achieved using a comprehensive algorithm. Remarkably, our CUDA-powered GPU could navigate complex paths up to the 6th loop, like USDT->A->B->C->D->E->USDT, resulting in significant arbitrage gains. As of today, propelled by the AI-induced computational race, we've been able to effortlessly establish several terabytes of high-speed storage and exponentially boost our computational capacity. By drastically enhancing Trie and integrating hundreds of thousands of CUDA parallel computational units, we are poised to massively expand the capabilities of the Computing Platform. We transitioned Trie to high-speed VRAM from its conventional storage form, boosting its concurrent processing ability through innovative sharding algorithms. Furthermore, we achieved seamless state synchronization across various regions via temporal synchronization. Although transforming computing units from sequential to asynchronous parallel processing and shifting to synchronized algorithms for state access might still hinge on the efficiency of state storage, we anticipate that separating algorithms and storage for well-designed contract codes will lead to substantial scalability. Looking ahead, 0xVM plans to migrate the VM onto a heterogeneous computing platform, delving into the myriad applications made possible by AI's immense computational strength. This move signifies a critical advancement in leveraging AI and heterogeneous computing's power for blockchain and smart contract technologies. **Challenge** The experiments and reasoning we've conducted are logically sound, but they come with their own set of significant challenges. A notable issue is the unpredictability in the outcomes produced by complicated smart contracts. This begs the questions: How can we verify these results and maintain consistency? This becomes particularly pressing after integrating CUDA technology, which has led to an incredible increase in performance by a factor of a thousand. A crucial dilemma we face is how to effectively merge heterogeneous parallel processing with serial state synchronization, without compromising on efficiency. Our lab has previously conducted tests on the TON blockchain, which operates on an asynchronous basis and does not guarantee strict consistency. If the TON model is deemed feasible, it suggests that our theoretical approach of running smart contracts using CUDA is also achievable. We are currently exploring the hypothesis that a single GPU equipped with 20,000 CUDA cores might offer a performance enhancement of up to 5,000 times. The prospect of such an advancement is indeed very exciting and eagerly awaited. # Tokenomics The XVM tokenomics is carefully designed to ensure sustainable growth and incentivize all key stakeholders within the ecosystem.

# Token Utility $XVM is the staking and utility token of 0xVM. By prioritizing staking, we reduce liquidity of $XVM on the open market, enhancing the longer-term stability and security of the 0xVM Network. The 0xVM token economics, or tokenomics, are subject to iterative improvement updates based on governance decisions taken by the larger community of $XVM holders.

However, as the blockchain ecosystem evolves, the limitations inherent in Bitcoin's original design become increasingly apparent. Notably, Bitcoin lacks the capability to support Turing-complete smart contracts and faces significant challenges in achieving high transaction throughput. These constraints limit the scope of applications and innovations that can be built on Bitcoin's secure and decentralized platform. In response to these challenges, we introduce 0xVM, a groundbreaking solution designed to enhance Bitcoin's functionality without compromising its foundational principles of security and decentralization. 0xVM is a Turing-complete virtual machine that operates directly within Bitcoin's consensus layer, integrating an execution layer and a data consistency layer. This integration leverages Bitcoin's robust consensus mechanism, ensuring secure, immutable transaction logging and network integrity. The 0xVM design addresses traditional security and scalability issues by encoding virtual machine operations directly into Bitcoin's UTXOs, thereby eliminating the need for additional transaction signatures. This innovative approach not only enhances the security and decentralization of the network but also reduces transaction overhead, making the system more efficient. Furthermore, 0xVM introduces a novel transaction ordering mechanism based on VM gas fees, aimed at mitigating the economic impact of Miner Extractable Value (MEV). This mechanism prioritizes transactions in a way that optimizes profits for 0xVM nodes, ensuring a more equitable distribution of rewards within the network. Looking ahead, 0xVM is poised for continuous improvement. Future developments will focus on enhancing the system's scalability through improved encoding efficiency and the implementation of parallel processing capabilities. These advancements will ensure that 0xVM can support an ever-increasing volume of transactions and more complex decentralized applications (DApps). In summary, 0xVM represents a significant leap forward for the Bitcoin ecosystem. By enabling Turing-complete smart contracts and scalable transaction processing directly on the Bitcoin blockchain, 0xVM not only preserves the security and decentralization ethos of Bitcoin but also extends its utility, paving the way for a new generation of decentralized applications. # Background {% content-ref url="/pages/TaoD9vWxdGTqiAm1YrG2" %} [Overview of Bitcoin's Limitations](/what-is-0xvm/background/overview-of-bitcoins-limitations) {% endcontent-ref %} {% content-ref url="/pages/HfmnGQw31uUeNdtLYOYm" %} [The Need for Enhancements](/what-is-0xvm/background/the-need-for-enhancements) {% endcontent-ref %} {% content-ref url="/pages/AQ1xRPvRsLLrz49r8tGv" %} [Existing Layer-2 Solutions](/what-is-0xvm/background/existing-layer-2-solutions) {% endcontent-ref %} # Overview of Bitcoin's Limitations **1. Overview of Bitcoin's Limitations** Bitcoin, introduced by the pseudonymous Satoshi Nakamoto in 2008, revolutionized the financial landscape by establishing a decentralized, peer-to-peer digital currency. Its robust security, immutability, and decentralized nature have made it the premier cryptocurrency and a trusted store of value. However, as the blockchain ecosystem continues to evolve, several intrinsic limitations of Bitcoin's original design have surfaced, posing significant challenges to its scalability and broader applicability. **1.1 Lack of Turing-Complete Smart Contracts** One of the most notable limitations of Bitcoin is its inability to natively support Turing-complete smart contracts. Bitcoin's scripting language, Script, is deliberately simplistic and non-Turing complete. This design choice prioritizes security and simplicity but severely restricts the complexity of operations that can be executed on the Bitcoin blockchain. Script supports only basic operations, such as multi-signature requirements, hashlocks, and time-locks, which are sufficient for simple transactions but inadequate for more complex decentralized applications (DApps). In contrast, platforms like Ethereum have embraced Turing-complete languages, such as Solidity, enabling the creation of complex smart contracts that can execute arbitrary logic. This capability has unlocked a vast array of applications, from decentralized finance (DeFi) and non-fungible tokens (NFTs) to automated governance and beyond. Bitcoin's lack of native support for such functionality limits its potential to serve as a versatile platform for innovation. **1.2 Constrained Transaction Throughput** Bitcoin's architecture is also constrained by its limited transaction throughput. The Bitcoin network processes transactions in blocks, with each block added approximately every 10 minutes. The block size is capped at 1 megabyte, which translates to a maximum of about 7 transactions per second (tps). This throughput is significantly lower than that of traditional payment systems like Visa, which can handle thousands of transactions per second. The limited throughput leads to congestion during periods of high demand, resulting in slower transaction confirmations and higher fees. This scalability issue undermines Bitcoin's potential as a mainstream transactional currency and restricts its utility in environments requiring high-speed, high-volume transaction processing. **1.3 High Transaction Fees** As a direct consequence of constrained throughput, transaction fees on the Bitcoin network can become prohibitively high during times of network congestion. Users must bid higher fees to incentivize miners to prioritize their transactions. While this mechanism helps manage network congestion, it also creates a barrier for small, everyday transactions, making Bitcoin less practical for regular use as a payment method. **1.4 Energy Consumption** Bitcoin's proof-of-work (PoW) consensus mechanism, while ensuring security and decentralization, is extremely energy-intensive. The process of mining involves solving complex cryptographic puzzles, which requires substantial computational power and electricity. This high energy consumption has raised environmental concerns and drawn criticism from various quarters. Although solutions like renewable energy sources and more efficient mining hardware are being explored, the energy footprint of Bitcoin remains a significant limitation. **1.5 Limited Privacy** Despite being pseudonymous, Bitcoin transactions are not inherently private. Every transaction is recorded on a public ledger, allowing anyone to trace the flow of funds between addresses. While this transparency is a fundamental feature of blockchain technology, it can be a drawback for users requiring privacy. Advanced cryptographic techniques, such as zero-knowledge proofs, have been implemented on other blockchains to enhance privacy, but Bitcoin has been slow to adopt such innovations. **1.6 Slow Adaptation to Innovation** Bitcoin's development process is characterized by a conservative approach to changes, prioritizing stability and security over rapid innovation. This cautious approach, while beneficial in maintaining a robust and secure network, also means that Bitcoin is slower to adopt new technologies and improvements. Governance processes, which require broad consensus for changes, can delay the implementation of essential updates and enhancements. **Conclusion** In summary, while Bitcoin has laid the foundational groundwork for decentralized digital currencies, its limitations in supporting complex smart contracts, constrained transaction throughput, high transaction fees, significant energy consumption, limited privacy, and slow adaptation to innovation present substantial challenges. Addressing these limitations is crucial for Bitcoin to maintain its relevance and competitiveness in the evolving blockchain landscape. The introduction of 0xVM aims to overcome these challenges by enhancing Bitcoin's capabilities without compromising its core principles of security and decentralization. # The Need for Enhancements As the blockchain ecosystem evolves and matures, the demand for more sophisticated functionalities and greater scalability has become increasingly apparent. While Bitcoin remains a foundational pillar of the cryptocurrency world, its inherent limitations hinder its ability to fully meet the growing needs of users and developers. Enhancements to Bitcoin's infrastructure are essential to ensure it remains competitive and capable of supporting a wider array of applications. Here, we explore the driving factors behind the necessity for these enhancements. **2.1 Expanding Use Cases Beyond Digital Currency** Bitcoin's original design as a decentralized digital currency has proven immensely successful. However, the blockchain space has expanded far beyond simple value transfers. The rise of decentralized finance (DeFi), non-fungible tokens (NFTs), and decentralized autonomous organizations (DAOs) illustrates the vast potential of blockchain technology. These applications require more advanced functionalities than Bitcoin's current capabilities. Enhancing Bitcoin to support Turing-complete smart contracts would enable the creation of complex decentralized applications (DApps), positioning Bitcoin as a versatile platform for a broader range of use cases. **2.2 Enhancing Transaction Throughput** Bitcoin's transaction throughput is limited to approximately 7 transactions per second (tps), which is insufficient for global-scale applications. During periods of high demand, the network can become congested, leading to slower transaction confirmations and higher fees. This bottleneck restricts Bitcoin's usability for everyday transactions and hampers its adoption as a mainstream payment system. Enhancements that increase transaction throughput are critical to addressing these scalability issues, ensuring that Bitcoin can handle a larger volume of transactions efficiently. **2.3 Reducing Transaction Fees** High transaction fees are a significant barrier to the widespread use of Bitcoin for small, everyday transactions. When network congestion increases, users must compete by offering higher fees to prioritize their transactions, making it cost-prohibitive for low-value transactions. Reducing transaction fees through scalability improvements and more efficient transaction processing mechanisms is essential to making Bitcoin a practical option for all types of financial activities. **2.4 Addressing Energy Consumption** Bitcoin's proof-of-work (PoW) consensus mechanism, while securing the network, requires significant energy consumption. This high energy usage has environmental implications and attracts criticism from various sectors. Enhancements that optimize the efficiency of transaction processing and explore alternative consensus mechanisms or complementary technologies are necessary to mitigate Bitcoin's environmental impact and ensure its sustainability in the long term. **2.5 Improving Privacy** While Bitcoin transactions are pseudonymous, they are not inherently private. The public nature of the blockchain allows for the tracing of transaction flows, which can be a disadvantage for users requiring confidentiality. Enhancing Bitcoin's privacy features, possibly through the integration of advanced cryptographic techniques such as zero-knowledge proofs or ring signatures, would provide users with greater transaction privacy and protect sensitive financial data. **2.6 Accelerating Innovation and Adoption** Bitcoin's development process is characterized by a conservative approach, with changes requiring broad consensus. While this ensures network stability and security, it also slows the adoption of new technologies and improvements. A more agile approach to implementing enhancements would allow Bitcoin to keep pace with rapid advancements in the blockchain space. Establishing mechanisms for smoother protocol updates and fostering a more dynamic development environment would accelerate innovation and adoption. **2.7 Ensuring Decentralization and Security** Any enhancements to Bitcoin must preserve its core principles of decentralization and security. As Bitcoin scales and incorporates more complex functionalities, maintaining a robust, secure, and decentralized network becomes increasingly challenging. Ensuring that enhancements do not compromise these fundamental attributes is crucial to maintaining user trust and the integrity of the Bitcoin network. **Conclusion** The need for enhancements to Bitcoin is driven by the evolving demands of the blockchain ecosystem and the desire to maintain Bitcoin's relevance and utility in a rapidly changing landscape. By expanding its capabilities to support more complex applications, increasing transaction throughput, reducing fees, addressing energy consumption, improving privacy, accelerating innovation, and ensuring the continued decentralization and security of the network, Bitcoin can evolve to meet the needs of its users while preserving its foundational strengths. The introduction of 0xVM represents a strategic initiative to achieve these goals, positioning Bitcoin for continued success and broader adoption in the future. # Existing Layer-2 Solutions To address Bitcoin's inherent limitations, the blockchain community has developed several layer-2 solutions. These solutions aim to enhance Bitcoin's scalability, transaction throughput, and functionality without altering its core protocol. While these layer-2 solutions have achieved varying degrees of success, they also present challenges related to security, centralization, and complexity. Here, we explore some of the most prominent layer-2 solutions and their respective strengths and weaknesses. **Lightning Network** The Lightning Network is one of the most widely known and implemented layer-2 solutions for Bitcoin. It introduces an off-chain, payment channel network designed to facilitate fast, low-cost transactions by enabling participants to transact directly without broadcasting every transaction to the Bitcoin blockchain. **How It Works** The Lightning Network operates by establishing bi-directional payment channels between users. These channels are funded by an initial on-chain Bitcoin transaction, locking funds in a multi-signature address. Once a channel is open, participants can transact freely off-chain, updating the balance between them without incurring the delays and costs associated with on-chain transactions. When the channel is closed, a final on-chain transaction reflects the net outcome of all off-chain transactions, updating the Bitcoin ledger accordingly. **Strengths** * **Scalability:** By moving most transactions off-chain, the Lightning Network significantly reduces the burden on the Bitcoin blockchain, allowing for higher transaction throughput. * **Low Fees:** Off-chain transactions avoid the high fees associated with on-chain transactions, making microtransactions feasible. * **Speed:** Transactions are nearly instantaneous, as they do not require confirmation by the entire network. **Weaknesses** * **Complexity:** Setting up and managing payment channels can be complex for end-users, requiring technical knowledge. * **Security:** While the Lightning Network is designed to be secure, it relies on the assumption that participants are online and able to monitor the network to prevent fraud. * **Centralization Risks:** There is a potential risk of centralization if a few large nodes dominate the network, undermining the decentralized ethos of Bitcoin. **Liquid Network** The Liquid Network, developed by Blockstream, is a federated sidechain designed to enhance Bitcoin's functionality by enabling faster transactions, confidential transactions, and the issuance of digital assets. **How It Works** Liquid operates as a sidechain to Bitcoin, meaning it runs its own blockchain that is anchored to the Bitcoin network. Bitcoin can be transferred to the Liquid Network via a process called "pegging," where Bitcoin is locked on the main chain and an equivalent amount of Liquid Bitcoin (L-BTC) is issued on the Liquid sidechain. This L-BTC can be transacted on Liquid's blockchain with enhanced features such as confidential transactions, which hide transaction amounts, and faster block times. **Strengths** * **Enhanced Privacy:** Confidential transactions ensure that transaction amounts are hidden, enhancing privacy. * **Faster Transactions:** The Liquid Network's faster block times allow for quicker transaction confirmations. * **Asset Issuance:** Liquid supports the issuance of digital assets, enabling tokenized securities, stablecoins, and other financial instruments. **Weaknesses** * **Federation Model:** Liquid relies on a federation of trusted entities to operate, introducing a level of centralization and trust that is not required in Bitcoin's native network. * **Complexity and Cost:** The pegging process and the requirement to interact with a separate blockchain add complexity and potential costs for users. **Stacks** Stacks (formerly Blockstack) is a layer-2 solution that brings smart contract functionality to Bitcoin, enabling developers to build decentralized applications (DApps) with enhanced capabilities. **How It Works** Stacks introduces a new programming language called Clarity, which is designed for writing smart contracts that are both predictable and secure. Stacks transactions are settled on the Bitcoin blockchain, providing the security and immutability of Bitcoin while enabling advanced functionalities through Clarity smart contracts. **Strengths** * **Smart Contracts:** Stacks extends Bitcoin's functionality by enabling Turing-complete smart contracts. * **Security:** By leveraging Bitcoin's blockchain for transaction settlement, Stacks inherits Bitcoin's robust security model. * **Developer-Friendly:** Clarity is designed to be more predictable and less prone to errors than other smart contract languages, making it easier for developers to write secure contracts. **Weaknesses** * **Token Dependency:** Stacks relies on its native token (STX) for network operations, which adds an additional layer of complexity for users and developers. * **Adoption:** The use of a new programming language and the requirement for a separate token can hinder widespread adoption among developers and users accustomed to existing platforms like Ethereum. **Conclusion** While existing layer-2 solutions such as the Lightning Network, Liquid Network, and Stacks have made significant strides in addressing Bitcoin's limitations, they each come with their own sets of challenges related to security, centralization, complexity, and user adoption. These solutions highlight the ongoing efforts within the blockchain community to enhance Bitcoin's functionality and scalability. However, the need for a more integrated and secure approach remains. 0xVM aims to address these challenges by providing a Turing-complete virtual machine directly within Bitcoin's consensus layer, offering a more holistic and seamless enhancement to Bitcoin's capabilities. # Basic Ideas {% content-ref url="/pages/JJN6am4X2vNAUhUpTmKe" %} [Introduction to 0xVM](/what-is-0xvm/basic-ideas/introduction-to-0xvm) {% endcontent-ref %} {% content-ref url="/pages/5ynrZgXODH5tY4Db06SE" %} [Introduction to Key Technologies](/what-is-0xvm/basic-ideas/introduction-to-key-technologies) {% endcontent-ref %} {% content-ref url="/pages/78vGLUCEodoFtiEEvyH3" %} [Comparison with Existing Technologies](/what-is-0xvm/basic-ideas/comparison-with-existing-technologies) {% endcontent-ref %} # Introduction to 0xVM As the digital economy continues to grow and the use cases for blockchain technology expand, there is a pressing need to enhance Bitcoin's foundational infrastructure. 0xVM addresses this need by introducing a Turing-complete virtual machine that operates directly within Bitcoin's consensus layer. This innovative approach extends Bitcoin's functionality beyond simple transactions, enabling it to support complex decentralized applications (DApps) while maintaining the core principles of security and decentralization. 0xVM leverages Bitcoin's robust consensus mechanism, ensuring secure and immutable transaction logging and network integrity. By integrating an execution layer and a data consistency layer, 0xVM addresses the limitations of existing layer-2 solutions, which often struggle with issues related to security and centralization. **Key Components of 0xVM** 1. **Execution Layer**: The execution layer is responsible for processing and executing transactions encoded with 0xVM-specific code. Unlike traditional off-chain solutions, 0xVM operates within Bitcoin's consensus layer, ensuring that all transactions are securely recorded on the Bitcoin blockchain. This layer enables the execution of complex operations and smart contracts, significantly expanding Bitcoin's utility. 2. **Data Consistency Layer**: The data consistency layer ensures that all transactions and state transitions are accurately and immutably logged. This layer maintains network integrity by leveraging Bitcoin's robust ledger, allowing for the restoration of the 0xVM state even in the event of node failures. By ensuring data consistency, this layer supports the long-term reliability and transparency of the network. 3. **UTXO-Based VM Operations**: One of the key innovations of 0xVM is the encoding of virtual machine operations into Bitcoin's UTXOs. This approach circumvents the need for additional transaction signatures, reducing overhead and enhancing scalability. By leveraging Bitcoin's existing transaction model, 0xVM can seamlessly integrate advanced functionalities without disrupting the network's foundational architecture. 4. **Gas Fee-Based Transaction Ordering**: To address the economic impact of Miner Extractable Value (MEV), 0xVM introduces a novel transaction ordering mechanism based on VM gas fees. This mechanism prioritizes transactions by gas fees rather than layer-1 fees, ensuring a fairer distribution of profits for 0xVM nodes and reducing the influence of miners on transaction ordering. This approach mitigates MEV-related issues and promotes a more equitable network environment. 5. **Security and Decentralization**: 0xVM upholds the security and decentralization ethos of Bitcoin by leveraging its robust consensus mechanism. All transactions are securely recorded on the Bitcoin blockchain, and the integration of an execution layer within the consensus layer eliminates the centralization risks associated with off-chain solutions. This ensures that 0xVM can support complex operations while maintaining the security and trustlessness that Bitcoin is known for. **Future Developments and Enhancements** 0xVM is designed with scalability and future enhancements in mind. The project aims to improve encoding efficiency and enable parallel processing capabilities, further enhancing the system's ability to handle a high volume of transactions and support more complex DApps. By continuously evolving and integrating new technologies, 0xVM seeks to remain at the forefront of blockchain innovation, ensuring that Bitcoin can meet the growing demands of the digital economy. In summary, 0xVM represents a significant advancement in the Bitcoin ecosystem. By introducing a Turing-complete virtual machine directly within Bitcoin's consensus layer, 0xVM extends Bitcoin's utility, enabling it to support a wide range of decentralized applications. This innovative approach addresses the limitations of existing layer-2 solutions, providing a more secure, decentralized, and scalable solution for the future of blockchain technology. # Introduction to Key Technologies To fully grasp the innovation behind 0xVM, it is essential to understand the key technologies that underpin its design and functionality. This section provides an in-depth exploration of these foundational concepts, highlighting their importance and how they contribute to the overall capabilities of 0xVM. **Turing-Complete Smart Contracts** **Turing-completeness** refers to a system's ability to perform any computation that can be described algorithmically, given sufficient resources. In the context of blockchain, Turing-complete smart contracts can execute complex logic, enabling the creation of decentralized applications (DApps) that go beyond simple transactional functions. Bitcoin's scripting language, Script, is intentionally limited and non-Turing complete to prioritize security and simplicity. However, this restriction prevents Bitcoin from supporting the complex operations needed for modern DApps. In contrast, Ethereum's Solidity language is Turing-complete, allowing for a wide range of applications such as decentralized finance (DeFi), non-fungible tokens (NFTs), and automated governance.

](https://0xvm-whitepaper.gitbook.io/0xvm-whitepaper/what-is-0xvm/transaction-mechanism-in-0xvm/transaction-execution) # Failed Execution In any blockchain network, transactions may sometimes fail due to various reasons such as insufficient funds, incorrect transaction formatting, or violations of smart contract logic. The 0xVM framework handles failed executions with robust mechanisms to ensure network stability, transparency, and user confidence. This section outlines the processes and protocols involved in dealing with failed transactions within the 0xVM network. **Core Components of Failed Execution Handling** 1. **Validation Failures** Transactions that fail during the validation phase do not proceed to execution. Common causes include insufficient balance, invalid signatures, or incorrect nonce values. **Process:** * The transaction is checked against the sender's balance to ensure sufficient funds. * Signature verification is performed to confirm the authenticity of the transaction. * Nonce values are checked to prevent replay attacks. * If any of these checks fail, the transaction is rejected, and the sender is notified. 2. **Execution Failures** Even if a transaction passes initial validation, it may fail during execution due to errors in the smart contract logic, such as out-of-gas errors or logical inconsistencies. **Process:** * The virtual machine executes the transaction instructions. * If an error occurs during execution (e.g., out-of-gas, invalid opcode, or logical error), the execution is halted. * The state changes resulting from the partial execution are reverted to maintain network consistency. 3. **Error Logging and Notification** All failed transactions are logged with detailed error messages to facilitate debugging and provide transparency. **Process:** * Detailed error logs are generated, including the reason for failure and the transaction details. * Users are notified of the failure through appropriate channels (e.g., wallet notifications, network explorers). * Error logs are stored for auditing and analysis purposes. 4. **Gas Handling for Failed Transactions** Unlike successful transactions, failed transactions do not result in state changes, but they still consume computational resources. To account for this, gas fees are handled differently for failed transactions. **Process:** * A portion of the gas fee is consumed based on the computational resources used before the failure occurred. * The remaining gas is refunded to the sender. * This mechanism ensures that users are not overly penalized for failed transactions while still accounting for the resources consumed. **Detailed Process of Handling Failed Execution** 1. **Transaction Submission:** * The user creates and signs a transaction. * The transaction is broadcast to the 0xVM network. 2. **Validation Phase:** * The transaction undergoes validation checks (balance, signature, nonce). * If validation fails, the transaction is rejected, and the sender is notified. 3. **Execution Phase:** * If validation succeeds, the transaction is executed by the virtual machine. * During execution, the transaction may fail due to errors in the contract logic. * If execution fails, the state changes are reverted to maintain consistency. 4. **Logging and Notification:** * Detailed error logs are generated and stored. * Users are notified of the transaction failure and the reason for the failure. 5. **Gas Fee Handling:** * The gas fee is partially consumed based on the computational effort before failure. * The remaining gas is refunded to the sender. **Security and Integrity** Ensuring the security and integrity of the network during failed transactions involves several measures: * **Reversion of State Changes:** Ensures that any changes made during partial execution are reverted, maintaining network consistency and integrity. * **Detailed Error Logging:** Provides transparency and aids in debugging, helping developers identify and fix issues in their smart contract code. * **Gas Fee Management:** Fairly charges users for the computational resources consumed, discouraging misuse and ensuring efficient resource utilization. **Advantages of Robust Failed Execution Handling in 0xVM** 1. **Enhanced Reliability:** * By reverting state changes on failure, the network maintains a consistent and reliable state, preventing erroneous transactions from affecting the overall system. 2. **User Transparency:** * Detailed error logs and notifications ensure that users are informed about the status of their transactions, fostering trust and transparency. 3. **Efficient Resource Utilization:** * Proper handling of gas fees ensures that computational resources are fairly compensated, preventing abuse and optimizing network performance. 4. **Developer Support:** * Comprehensive error logging aids developers in diagnosing and resolving issues, improving the overall quality and robustness of smart contracts deployed on the network. **Future Enhancements** To further enhance the handling of failed transactions, 0xVM plans to implement several improvements: * **Enhanced Debugging Tools:** * Providing developers with more advanced tools and interfaces for debugging failed transactions. * **Improved Error Messages:** * Offering more descriptive and actionable error messages to help users and developers understand the reasons for transaction failures. * **Adaptive Gas Management:** * Implementing more sophisticated gas management techniques to optimize resource usage and reduce the impact of failed transactions. In summary, the handling of failed transactions in 0xVM is designed to ensure network stability, transparency, and efficient resource utilization. By implementing robust validation, execution reversion, detailed logging, and fair gas fee management, 0xVM maintains a reliable and secure environment for executing complex smart contracts and transactions on the Bitcoin blockchain. # Transaction Gas and Automated Gas Market In the 0xVM network, the transaction gas mechanism and the automated gas market play crucial roles in ensuring efficient and fair execution of transactions. Gas fees are essential for preventing spam, allocating network resources, and prioritizing transactions. The automated gas market further enhances this system by dynamically adjusting gas prices based on network demand, ensuring optimal resource utilization and user experience. **Core Components of the Gas Mechanism** 1. **Gas Calculation and Limits** Each transaction in 0xVM requires a certain amount of computational work, measured in gas. The gas required depends on the complexity of the transaction, including the execution of smart contracts and other operations. **Process:** * **Gas Calculation:** The virtual machine calculates the gas required based on the operations involved in the transaction. * **Gas Limit:** Users set a gas limit for their transactions to prevent excessive resource consumption. This limit caps the maximum gas a transaction can consume. * **Gas Price:** Users specify the gas price they are willing to pay, denominated in a subunit of the native cryptocurrency (e.g., satoshis per gas unit). 2. **Transaction Execution and Gas Consumption** During transaction execution, the specified gas is consumed as the virtual machine processes each operation. If the gas consumed reaches the gas limit, the transaction fails, and any changes are reverted, but the gas spent up to that point is not refunded. **Process:** * **Execution:** The transaction is executed, and gas is consumed for each computational step. * **Out-of-Gas Handling:** If the gas limit is reached, the transaction is reverted, but the gas consumed is not refunded to compensate for the computational resources used. 3. **Automated Gas Market** The automated gas market dynamically adjusts gas prices based on network demand, ensuring efficient allocation of resources and optimal transaction throughput.

0xVM nodes and Bitcoin transactions

To understand the nodes in 0xVM, let’s follow a 0xVM-compatible Bitcoin transaction through the system. 1. The **Router Node** monitors the Bitcoin Network for UTXOs with 0xVM-compatible instructions. 0xVM instructions can target different VMs such as EVM, SVM, or others. The Router Node inspects the 0xVM instructions and forwards it to the relevant type of Operator Node 2. The **Operator Node** receives the instructions from the Router Node and executes them. It then broadcasts the new state across the network for consensus. 3. The **Validator Node** seeks consensus through a majority agreed-upon state from the Operator Nodes’ execution state changes. It is also responsible for ensuring the accuracy of historical state changes recorded by the Data Consistency Layer Nodes. Validator Nodes are critical to maintaining the integrity of the 0xVM network. Rights to operate a Validator Node can be purchased from our website. The **Data Consistency Layer** supports the other nodes by providing up-to-date records of all historical 0xVM transactions. Architecturally, as the authoritative source for all 0xVM state updates, they also reduce the storage burden and hardware requirements of running other 0xVM nodes.

As an example, if we were at day 5 since node sales started (day 5 of the program), and there are 5,000 active Verifier Nodes, each active node would be entitled to 140 $XVM daily. 700,000 / 5,000 = 140. This equates to 4,200 $XVM per month per node. You can transparently monitor your rewards from the node management web portal after having purchased your nodes. ### Daily $XVM Emission Schedule The following table shows the emission schedule for 0xVM Rewards Pool Program, $XVM rewards, over time starting with day 1, the first day the nodes are sold.

### Withdrawing earned $XVM The $XVM earned through your node rewards is subject to a short unlocking period. The redemption rate varies depending on when you unlock it, starting with 25% for immediate unlock and ends with 100% on day 30. The token lockup schedule is in place as an effort to help control token circulation and helps to support the longevity and stability of the network for the benefit of all.

Note that only withdrawals to BNB Chain are supported. ### How do nodes generate returns? Node holders earn daily $XVM token rewards through mining, with a structured release schedule over four years. ### What are the main functions of the node? Validator Nodes play a crucial role in 0xVM’s ecosystem as they uphold the integrity of other nodes operating within the 0xVM Network. The Validator Node seeks consensus through a majority agreed-upon state from the Operator Nodes’ execution state changes. It is also responsible for ensuring the accuracy of historical state changes recorded by the Data Consistency Layer Nodes. Validator Nodes are critical to maintaining the integrity of the 0xVM network. Rights to operate a Validator Node can be purchased from our website. For more information on 0xVM nodes, please refer to our GitBook documentation. ### How is the daily mining reward calculated? When is it distributed? The daily mining reward depends on the size of the daily reward pool and the number of running nodes. Initially, the reward pool is set at 700,000 $XVM / day, with a halving scheduled every 6 months. Rewards are distributed daily at 00:00 UTC. ### What's the token release strategy? The token release strategy for $XVM mining rewards is as follows: * Initial daily distribution: 700,000 $XVM per day * Halving schedule: The daily distribution is halved every 6 months * Program duration: 48 months (4 years) * 26% of the overall token supply is allocated for $XVM mining rewards Note that a month in the schedule above is equivalent to 30 days. Consequently, based on a 30-day month calculation, the full duration of the program is 1,440 days. Note that, when the 48 month program ends and all associated $XVM have been fully distributed, a total of 25.1% of $XVM will have been used up. Since mining reward allocation is 26% of overall token supply this leaves a 0.9% buffer of the $XVM reward pool free to allocate for other mining reward purposes. ### What is the maximum supply cap of nodes? The maximum supply cap for 0xVM Validator Nodes is 50,000. ### How does node pricing work? The initial price is $700. The price remains fixed for the first 10,000 nodes. After that, the price increases by $1 for every 10 nodes sold. ### Is the node transferable? Initially, nodes are non-transferable. However, this does not affect your ability to delegate node operation or participate in mining. The transfer functionality may be enabled in a future update. ### What Blockchains are supported? * For purchasing nodes: Ethereum, Arbitrum One, and BNB Chain * For receiving referral cashbacks: BNBChain * For receiving $XVM, mining rewards: Ethereum For more information on purchasing a node: [How to Buy Nodes](/validator-node-sale/how-to-buy-nodes). For instructions on how to withdraw referrals, see [Referral Rewards](/validator-node-sale/rewards/referral-rewards). ### How can I get help if I encourage programs during the purchase process?

The $XVM earned through your node rewards is subject to a short unlocking period. The redemption rate varies depending on when you unlock it, starting with 25% for immediate unlock, 50% on day 10, and ends with 100% on day 30. The token lockup schedule is in place as an effort to help control token circulation and helps to support the longevity and stability of the network for the benefit of all. ### How long after I purchase a node can I see it in my dashboard? The waiting time depends on the blockchain you use for payment. You'll be able to see the node in your dashboard once the transaction is confirmed on the blockchain. ### What chains will the rewards be sent to? How frequently? * For receiving referral cashbacks: BNB Chain * For receiving XVM, mining rewards: Ethereum XVM rewards from the token pool are distributed daily. Referral bonuses are distributed immediately to the referring user’s web portal account upon successful sale of referred nodes. Network participation rewards (revenue share, gas fees, etc.) are distributed as and when the activities take place. Other rewards (airdrops, perks) are distributed on an ad-hoc basis as and when the program for the reward deems it appropriate. ### Can I buy nodes as a gift to someone else? Yes, you can.

The recipient will see the nodes after logging into the web portal as soon as the blockchain transaction has been confirmed. # State Machines State machines help us model how a process goes from state to state when an event occurs. State machines are useful in software development because they help us capture all the states, events and transitions between them. Using state machines makes it easier to find impossible states and spot undesirable transitions. #### Benefits of state machines[​](https://stately.ai/docs/state-machines-and-statecharts#benefits-of-state-machines) * **Simple to understand.** State machines are visual and simple to understand. They’re a great way to communicate with your team and stakeholders. * **Simple to test.** State machines are deterministic, which means they’re simple to test. You can test all the possible states and transitions between them. * **Simple to implement.** State machines are simple to implement in solidity. * **Simple to maintain.** State machines are simple to maintain because they’re simple to understand, test and implement. * They provide a clear and concise way to model complex user interfaces and manage application state. * State machines can help reduce complexity and improve maintainability by providing a structured way to manage state transitions and handle events. * They can also help prevent bugs and improve code quality by enforcing a clear separation of concerns between different parts of the application. * Additionally, state machines can be highly maintainable and offer a way to make very complex back-end processes much more manageable. **In the backend**[**​**](https://stately.ai/docs/state-machines-and-statecharts#in-the-backend) * State machines simplify the design and implementation of complex workflows, which can help reduce complexity and improve maintainability.
