Xai leverages Arbitrum technology. # Xai Blockchain What is the Xai Blockchain? The Xai Blockchain, developed by Offchain Labs and overseen by the Xai Foundation, was custom-developed to address the needs of web3 gaming at scale. Tailored specifically for gaming, this blockchain offers traditional gamers an abstracted wallet and account experience, provides developers with increased gas and contract limits, and establishes a fully decentralized ecosystem that fosters trust and transparency for all participants. By leveraging Ethereum's robust security measures, the Xai Blockchain cements its resilience against potential hacks and other vulnerabilities. # Xai Foundation What is the Xai Foundation? The primary objective of the XAI Foundation is to foster the growth of developers and games within the XAI blockchain ecosystem. Its core functions include attracting 3rd party developers and games to the platform, facilitating effective marketing strategies for games deployed to Xai, and offering financing opportunities to web3 game developers. Additionally, the Xai Foundation assumes the pivotal role of serving as the custodian of the blockchain and its associated token, supporting integrity of the platform. # Xai Token What is the Xai Token? The Xai token will serve a dual purpose on the Xai blockchain. Firstly, it will function as the designated gas token, facilitating transactions within the network. Additionally, Xai tokens will be rewarded to validator nodes for their role in validating transactions. Moreover, the Xai token will act as the primary token within the gaming ecosystem, being accepted as payment for games and in-game items. # Blockchain Gaming # Current Limitations The existing challenges within the realm of blockchain gaming encompass a spectrum of issues that span from economic inefficiencies to user experience barriers, significantly affecting the industry's potential for mass and innovation. Let's delve into each of these problems with intricate detail: *** ### Wallet Interaction Hurdles Arguably one of the most significant obstacles to mainstream blockchain gaming adoption is the requirement for users to interact directly with cryptocurrency wallets. This cumbersome process can deter players who are not familiar with blockchain technology or are hesitant to manage wallets. Ideally, wallets should be seamlessly integrated into the backend of the gaming experience, effectively managed on behalf of the player to streamline onboarding and usage. *** ### Gas Fees One main concern in regards blockchain gaming is the issue of gas prices. The inefficiencies and congestion on certain blockchain networks lead to steep transaction fees, making even simple in-game actions economically impractical for players. This issue not only drives away potential users but also stifles the growth of blockchain gaming ecosystems. Over the past decade, free-to-play games have grown exponentially because they have reduced friction as much as possible. Blockchain games will benefit immensely if they can remove friction, including gas fees. *** ### Unstable Blockchains The stability of blockchain networks is another concern. Blockchains should provide a reliable and secure infrastructure for gaming, but many existing networks suffer from stability, resulting in buggy gameplay and frustrating user experiences. It's not realistic to expect players to play games that don’t work a notable percentage of the time because the logic is deployed via smart contracts to an unstable blockchain. *** ### Monetary-Focused Game Design A prevalent pitfall in the current landscape is the overemphasis on monetary rewards within game design. Many blockchain games prioritize aggressive tokenomics over creative and enjoyable gameplay experiences, which can alienate players seeking genuine entertainment value rather than solely financial gains. The 2021 bull run and subsequent bust proved that an over-reliance on in-game token rewards to drive user engagement is at best short lived. Game designers should study the trade that takes place in traditional games that are fun to play such as Counterstrike, Eve and Pokemon, and try to leverage blockchains to bring out the best in those styles of experiences. *** ### Complex Game and Economic Design Some blockchain games feature overly complex game and economic systems, which can prove overwhelming and confusing for new users. This steep learning curve discourages potential players from delving into and participating in these platforms, consequently impeding user acquisition and mass adoption. While crafting an intricate, doctoral-thesis-like exposition of your game world and economy might be intellectually stimulating, it is more likely to deter potential players than attract them. Such an approach is unlikely to contribute to the widespread adoption of blockchain technology. *** ### Lack of Creativity in Blockchain Benefits Blockchain technology offers a myriad of advantages, such as interoperability and composability. However, there is often a lack of imagination in how these benefits are incorporated into game design. The industry must strive to explore novel and innovative ways to leverage blockchain's capabilities to enhance gameplay and user experiences. Addressing these multifaceted challenges is pivotal to the evolution and growth of blockchain gaming. By reducing gas costs, improving blockchain stability, fostering creative game design, simplifying complex systems, and maximizing the potential of blockchain technology while minimizing user wallet interactions, the industry can unlock its true potential and deliver captivating gaming experiences to a broader audience, thus ushering in a new era of innovation and accessibility in blockchain gaming. # The Future of Gaming In the forthcoming era, all gamers will seamlessly engage with blockchain technology within their gaming experiences, yet they are unlikely to be consciously aware of its integration, including the use of technologies like NFTs. The 2021 cycle of blockchain games has illuminated the immense potential inherent in this technology. However, it has also underscored the substantial challenge presented by the adoption barrier that hinders many individuals from creating and managing their first crypto-wallets. To earnestly facilitate widespread adoption, the industry must undertake substantial initiatives to relegate wallet management and blockchain interaction to the background of gaming and application ecosystems, thus enabling users to effortlessly harness the benefits of blockchain technology without the need to interact with it directly. Within the gaming context, this transformation entails achieving complete ownership, facilitating open trade, fostering authentic in-game economies, ensuring interoperability, and enabling composability, all while shielded from the complexities of blockchain technology's underlying infrastructure. Upon achieving this pivotal goal, the industry's most cherished franchises, which captivate billions of individuals worldwide, will seamlessly unlock the advantages of blockchain technology without necessitating convoluted and cumbersome interactions. Such a development holds the extraordinary potential to exponentially amplify the scale of the blockchain industry, potentially increasing its reach and impact by orders of magnitude. The future of gaming, marked by effortless integration and unobtrusive blockchain utilization, promises to revolutionize entertainment on a global scale. # Gaming Evolved Blockchain gaming has long been held back by a series of significant challenges, ranging from gas fees to cumbersome wallet interactions. These hurdles have hindered the industry's growth and its ability to provide seamless, enjoyable experiences for players. However, a new network in the blockchain space, Xai, promises to reshape the landscape of blockchain gaming and usher in the much-anticipated era of frictionless, innovative gameplay. *** ### Addressing Gas Fees One of the most glaring issues in blockchain gaming has been the exorbitant gas fees that users encounter when conducting transactions on certain blockchain networks. Xai has recognized this challenge and is designed with a “gas subsidy” contract. This means games deployed to Xai will have gas fees subsidized by the network. As a result, players can expect to play games on Xai without the need to pay for gas fees. *** ### Ensuring Blockchain Stability Blockchain stability is vital for a smooth gaming experience. Xai's architecture prioritizes network reliability, ensuring minimal downtime and congestion. By providing a stable environment, Xai enables seamless gameplay, eliminating the frustrations often associated with more unreliable blockchain networks. *** ### Fostering Creative Game Design Xai is committed to fostering innovative game design that places the player experience at the forefront.

Within the Arbitrum ecosystem, there are a variety of chains and technologies at play. # Xai Basic Concepts ### Xai Summary Xai operates as an Arbitrum Orbit chain, harnessing Anytrust technology to achieve maximum speed and minimal costs. Unlike most Orbit chains that are "self-managed," Xai benefits from direct technical support courtesy of Offchain Labs. This support is not available to other orbit chains and is a crucial component of Xai as a strategic gaming initiative within the Arbitrum ecosystem. The strategy and growth of Xai's ecosystem are overseen by the Xai Foundation, and Offchain Labs provides technical assistance under the guidance of the Xai Foundation. In a departure from other Orbit chains, Xai boasts a canonical bridge within the Arbitrum ecosystem. Additionally, Xai incorporates unique enhancements, including elevated gas and contract limits, which foster a more favorable environment for ambitious blockchain game development and gameplay. Finally, Xai has its own custom gas fee token, self-named “$XAI”. *** ### Nitro All Arbitrum chains are built on top of Arbitrum Nitro, which is the foundational technology underneath all chains in the ecosystem. Nitro runs a fork of [Geth](https://docs.arbitrum.foundation/dao-glossary#geth) and uses WebAssembly as its underlying VM for fraud proofs. You can read about Nitro in detail [here](https://github.com/OffchainLabs/nitro/blob/master/docs/Nitro-whitepaper.pdf). *** ### Anytrust An Arbitrum protocol that manages data availability with a permissioned set of parties known as the[ Data Availability Committee (DAC)](https://docs.arbitrum.foundation/dao-glossary#data-availability-committee-dac). This protocol reduces transaction fees by introducing an additional trust assumption for data availability in lieu of Ethereum's[ Trustless](https://docs.arbitrum.foundation/dao-glossary#trustless) data availability mechanism. *** ### Arbitrum Layer2s [Arbitrum Nova](https://docs.arbitrum.foundation/dao-glossary#arbitrum-nova) is an example of an AnyTrust chain;[ Arbitrum One](https://docs.arbitrum.foundation/dao-glossary#arbitrum-one) is an alternative chain that implements the purely trustless (and more L1-gas intensive)[ Arbitrum Rollup Protocol](https://docs.arbitrum.foundation/dao-glossary#arbitrum-rollup-protocol). Both chains are built on top of Nitro. *** ### Orbit Chains Arbitrum Orbit lets 3rd parties create their own self-managed Arbitrum Rollup and AnyTrust chains. Arbitrum offers Rollup and AnyTrust technology for maximum flexibility in building Orbit chains. As with all chains in the Arbitrum ecosystem, both Arbitrum Rollups and Arbitrum Anytrust Orbit chains are built with Nitro as the underlying technology. *** # AnyTrust: Revolutionizing Blockchain Infrastructure Within the framework of AnyTrust, a cutting-edge variant of Arbitrum Nitro technology, Offchain Labs has harnessed innovation to address some of the most pressing challenges in the blockchain space. AnyTrust introduces a fresh perspective by incorporating a mild trust assumption to significantly reduce costs while ensuring robust data availability and security. # Reducing Costs through Trust Assumptions At the core of the Arbitrum protocol lies the necessity for all Arbitrum nodes, including validators who verify the chain's correctness and stake on accurate results, to have access to the data of every Layer 2 (L2) transaction within the Arbitrum chain's inbox. Traditionally, an Arbitrum rollup ensures data access by posting data on Layer 1 (L1) Ethereum as calldata, a process incurring substantial Ethereum gas fees, which is the primary cost component in Arbitrum. AnyTrust, however, introduces a paradigm shift by entrusting an external entity known as the Data Availability Committee (the "Committee") with the storage and on-demand provision of data. The Committee consists of N members, with a trust assumption that at least two members are honest. This trust assumption guarantees data availability for the proper functioning of the rollup protocol, as even if N-1 Committee members promise to provide access to certain data, at least one of the promising entities must be honest, ensuring data availability up to the specified expiration time. # Keysets for Flexibility Keysets play a crucial role in AnyTrust's architecture. They specify the public keys of Committee members and the requisite number of signatures to validate a Data Availability Certificate (DACert). Keysets provide the flexibility to change Committee membership and enable Committee members to update their keys as needed. Each Keyset includes the number of Committee members, the BLS public key for each member, and the number of signatures required. These Keysets are identified by their unique hashes, allowing them to be managed and tracked efficiently. # Data Availability Certificates (DACerts) A fundamental concept within AnyTrust is the Data Availability Certificate (DACert). A DACert encompasses the hash of a data block, an expiration time, and proof that N-1 Committee members have signed the (hash, expiration time) pair. This proof includes the hash of the Keyset used for signing, a bitmap indicating which Committee members signed, and a BLS aggregated signature over the BLS12-381 curve, attesting to the signatories. Due to the 2-of-N trust assumption, a DACert serves as evidence that a block's data will be accessible from at least one honest Committee member until the specified expiration time. This trust assumption underpins the reliability and security of data availability within the AnyTrust framework. # Dual Data Posting Mechanisms AnyTrust introduces dual methods for posting data blocks on L1. In addition to the conventional approach of posting full data blocks, it allows for the posting of DACerts, which prove data availability. The L1 inbox contract verifies the validity of DACerts, including reference to the valid Keyset specified within the DACert. L2 code, responsible for reading data from the inbox, is designed to handle both data formats seamlessly. When encountering a DACert, it performs validity checks, including ensuring the number of signers meets the Keyset requirements, validating the aggregated signature, and verifying that the expiration time extends beyond the current L2 timestamp. Valid DACerts ensure that the data block is accessible and can be utilized by the L2 code. # Data Availability Servers (DAS) Committee members operate Data Availability Servers (DAS), which expose two essential APIs: 1. Sequencer API: Meant exclusively for use by the Arbitrum chain's Sequencer, this JSON-RPC interface enables the Sequencer to submit data blocks to the DAS for storage. 2. REST API: Designed for broader accessibility, the RESTful HTTP(S)-based protocol allows data blocks to be retrieved by hash. It is fully cacheable, and deployments may incorporate caching proxies or CDNs to enhance scalability and protect against potential DoS attacks. Xai, along with Ex Populus and another trusted third party, are proud members of the Data Availability Committee (DAC). This setup allows AnyTrust chains to depend on a specialized DAC, rather than their parent chains, for data availability. The DAC members operate Data Availability Servers (DAS) which are crucial for storing and providing data on-demand. Below are the public keys for each of the trusted members. These keys can be used to authenticate and verify data signed by the respective entities within the Xai DAS ecosystem: Xai: `YBHz50DGYvPi02ynzcvcJS9K2nhXWKKSIZdDtXqxxoD3a1s2Fh2he79bMUWZ6M6qEhHM52HZr3l5jLoU4kOTBN+Q87yo0ljgZJYaphdYrHb+jabsPUcR+xdauJKAoKSkjQz8BWC9b2QZ3F7LK+Ro3cpWgkHR9SQlt86mk+eM71AWRl3ybwlRaxwAzYwOd9TRkQYARTY8fjvRmhChCY5lz7FtY0ttPrbJ3Mc2VXy5r0yyIoNFAQjg/jMNoablUOOIZRn+4KGLBQSPKcnl/Nv/0ZNdT563sLPj6mP3qLPlvwAhFpI5vIhSpGdpgJ8n8Ns3uxJyYsPD8qaHQciNLNTzYWGEze40CPMkxEeGRqi8yRoK8iuK5kse/+kqhBOyR3NVJg==` Ex Populus: `YA+ljLY01rxIncmXWl8bIZduwLObm0LKJIjzdyXjzH5FLN4Y+sUF2zjvF07aUPHOyADiV0y/+ztNO/iTpKLCVUzPzRHTtsukZaE3SUY+IIYU6NvUYdMXfhcKnHH3VU+iVRaSfiK2hw7OCfsge8AQcucdNlgaHSrdvlDmzAIx7jsemsLh8ov5dpywIVkWWZGY6wIwVh2/zUWBMZ4O3V3OYWppRttXZr2ukmwIDU5hQ4qtKRKemHaHSgb18QTuUsowMhkLwx2eW5hMOIYyzLV+NyUTyaQhkD0EtYISRBhHM7RinbP9LQWbLm0dnueZ9O3AkwnbH8w6/h3jkshPZx8hqJ6QH33SwbML1KIvOTEFvgBs7dnj9gbcfMq+17Bu3/YkWw==` LayerZero: [Public key](https://mainnet.xai.lznodes.com) `YAX5RGkb2ssH+fb3F+MTg0p+7jF3Le5BT8W/hIR7iSsgHvN2l435zpiSVuqOZNaIaQ/wyuGPur4m2hoiJ1d0J+r/VvbEYQGFCxPe6oi5JzIuAb/QlRA9lT+B1Rup8HKhcAAnSGaIowju3bSosv0LG04H0NlZOSRdJSFOIBA3WyfiK1867Nju+ZqfWF/TLUvR4AnIz2uNkZ7TzuIiA6mQnDHvpKSKsAUvhhAovG8Y8TI0iC1W/LSX1G9VVqFBeI2k1gDX3vzit2yN2PjskBfh5+N6bsIRSECZPRXBqskekNytvRlFveesFOwpXOmiyRPmFAwaYLtsQtSVjz94Ev5rabPQim7x1y9s6AEtV/Q/ggRU7/lTha1SVmMCRdYWWu3Igg==` Alt Layer: [Public Key](https://rollup-info.altlayer.io/xaiMainnet) `YAs1+BYgCS8HZ5vbTRT1nbt71wSvrFO3cFKUzWPXaud5V0ErIbWmk4ITu7VxEdDGnAyGmwwfVf2KjZXtsmDHYvXqED6z2fWva8RuY8wTrK5DYRVrPFpZxyFvfkO6j5TXyBPelZmJQzpQlFjx0eMoq4HFloDG1utysJywf3SqUuZKoU074I8pfkz4DSA8gomp6ACZNDBe+1rzvo4jFyzIKbhzveNanj9UWNEBJcrorD+ajWHW/Mrwn0P9RY5MeBt/CQQdCeHvOxTp95aWg2dXYv3iEB3WgH0i06da5gyjit809RYytX2x5I8pbgzugpsieBf8RrKq9FZujcdJJVAVtYJf/hWdptqcwEDdhfZTE2uMOVNJGFnwQ95wYdMT1jQpHA==` Team Secret: [Public key](https://xai.teamsecret.org/) `YAKvb8hRiZPIAext4QCk7ngBMmDVkAcQoAqc/BSXtU7/gUDohCF6RI29uc5OlOXIIhifqDOAe+RIDnUrkMJuXKM3f+21bngw9rgjuSoGfaXfqLffFlR3eIQs0QY0XQeG0RKYArEpJ/D/hOt7YPOddAXGn62x4ryWuyqt5mkyyWzfGrncElFsqT6Ni+hAjwjDOABlbMG6rvSrm6uyznjdL233pYO0DTe8S95wgYOcGLP8xSDHlN341schNnHTQyJAcxddkM3BEocKI7ymH9PNp12Ax5Y5SVZEXKkLFAECOwihaMjjH0brzYxdGbaPEEAgDQQbx8bvW09h5AnTEXPrz6oYWFRep/drK92rK9LtDM8NgnjzMLv+AeSd93X1DmZPpA==` Offchain Labs: [Public key](https://xai-das.offchainlabs.com/) `YAaEnUny7I1Stgrqdkdn5ob8omB9Id5dh2xtP87ifNORqK2gdi8NLU9Lw4PAXlg/pwPcmuYrAp8OZOPAw02Z5NOUhTKS+udcc7iSEST/tJ6CI1KeH2jXoToqA5FADD4hrwt7qHtu0RK56+zb3voUzyGnjt838DQH0UZSAMmsEZq8k/KCZPeej6IP03lSQOPxSQAAzbxLd3GZKk0V9tYEF9HCHxHjyJHHN7whXqovNDOE/vcw87RZzBlBeP9fOQ8HKRdEvB70DjshSupH/QeU5Znd034y+4NGiMvaCIkoZGb0/tZxHFc9yxp2Uy2HpaVVDxMmZYLSAsWIdsfkAMHKLmQ2ZtqW8Khd9M/uXOaEqTSu6yjJyizIDyXbA3FUuoW8uQ==` Other Third Party: `YBWhdxIOTQsrGcRQF8bHAEauHwl6F64farjSibsWDNPgplumU8MFRPn6X0jtBBMR1hH/aXso0ftQEI0edQVEB5dJkB4gymdhxq6hFCbYZpxsb8Ipr4lJe05WNmJRX1VeTRIu9WaeVLZlm+RMtvSuzbXXKJyNUnSZ420JaMKyR8Wt9M05nFZ832+eqer4eOtKDBX6gPBzdbUG+WRYdQlvFMkH/Nwo7LyKlHx231VIXKEIeuYXBmMxdtd0++QT7wi7PRN1XLjxGC8osyHYh3rksjBjG6urtgt4b/tVWyNevNaHT5YuO5MBPMMoQFgUqeV6dQiU3v2aXCwnnInTCjEvNbI5PUdwOosJi8JcdY7N1Vpm9jn8Gm89pCdwc8avTGWU5A==` # Sequencer-Committee Interaction When the Arbitrum sequencer intends to post a data batch using the Committee, it dispatches the data along with an expiration time to all Committee members in parallel via RPC. Each Committee member stores the data, signs the (hash, expiration time) pair using its BLS key, and returns the signature with a success indicator to the sequencer. Once sufficient signatures are collected, the Sequencer aggregates them to create a valid DACert for the (hash, expiration time) pair. This DACert is then posted to the L1 inbox contract, making it accessible to the AnyTrust chain software at L2. In cases where the Sequencer is unable to collect enough signatures within a designated timeframe, it resorts to a "fall back to rollup" strategy by posting the full data directly to the L1 chain. The L2 software is adept at comprehending both data posting formats (via DACert or full data) and handles each format appropriately. In conclusion, AnyTrust, a groundbreaking innovation within the Offchain Labs ecosystem, represents a pivotal advancement in addressing the challenges of data availability, security, and cost efficiency in blockchain infrastructure. Through a judicious trust assumption and a novel approach to data posting, AnyTrust paves the way for more scalable, accessible, and secure blockchain solutions. # Security considerations Xai — is an Arbitrum Orbit chain or L3 - It is purpose built to power web3 games which we believe will play a critical role in the future of gaming. Here are some risks you should know about before using the system: ## Bugs Offchain Labs’ [implementation](https://github.com/OffchainLabs/nitro) of the Arbitrum protocol (and therefor Xai network) has been carefully constructed, is perpetually being audited by several independent firms, and is continuously reviewed and tested following best engineering practices. That said, there remains a non-zero chance that their codebase contains some undiscovered vulnerabilities that puts user funds at risk. Users should carefully factor this risk into their decision to use Xai, and in deciding how much of their value to entrust into the system. ## Scams Xai, like Ethereum, is permissionless; on both platforms, anybody can deploy any smart contract code they want. Users should treat interacting with contracts on Xai exactly as they do with Ethereum, i.e., they should only do so if they have good reason to trust that the application is secure. ## Reporting Bugs and Scams Offchain Labs sponsors a [multi-million dollar bug bounty program](https://immunefi.com/bounty/arbitrum/) to incentivize any party who finds such a critical bug to disclose it responsibly. In addition, some tools that are available to the Xai community and ecosystem of developers have been developed by third parties under the guidance of the Xai Foundation.

XAI Circulating Supply

{% hint style="info" %} Note that XAI Circulating Supply chart excludes esXAI emissions, esXAI to XAI redemptions and XAI gas burning. For that information please visit [this dashboard](https://dune.com/xai_foundation/xai-network). Circulation amounts refer to numbers at end of each month. {% endhint %} # XAI & esXAI Emissions & Burning The **Maximum Total Supply** of XAI and esXAI combined amounts to 2.5 Billion tokens. **Total Supply** is the total amount of XAI and esXAI that exists at any given time, whether locked or unlocked. **Circulating Supply** is the total amount of XAI and esXAI that exists and is unlocked (excluding any locked portion). All of the gas fees paid in the Xai ecosystem are paid in XAI and burnt. The daily Sentry node emissions of esXAI hinge on the current Total Supply of both XAI and esXAI combined. XAI Total Supply undergoes reduction through the burning of XAI as gas within the Xai ecosystem. esXAI’s Total Supply also undergoes reduction through the burning of esXAI during the redemption process (depending on user inputs). The daily emission rate of esXAI remains dynamic, contingent upon the Total Supply of XAI and esXAI combined. Upon reaching key thresholds in Total Supply, esXAI emissions will automatically halve. Conversely, if the Total Supply contracts below the threshold of a halving event through burning, the emission rate of esXAI can increase to accommodate demand. These dual factors interact to establish a flexible and adaptive supply mechanism. This mechanism ensures enduring ecosystem rewards for the Sentry Keys, which solve key problems for the chain. Simultaneously, dynamic halving imposes constraints on the overall supply through negative pressure exerted on the quantity of tokens in circulation. Once the Total Supply reaches approximately half of the Maximum Total Supply, daily emissions begin to decrease. The reduction continues each time the Total Supply increases by half of the previous threshold value. The basic Emission Tranches are as follows: | ≤ 1,250,000,000 | 1,712,328.7671232900 | | --------------- | -------------------- | | ≤ 1,875,000,000 | 856,164.3835616440 | | ≤ 2,187,500,000 | 428,082.1917808220 | | ≤ 2,343,750,000 | 214,041.0958904110 | | ≤ 2,421,875,000 | 107,020.5479452050 | | ≤ 2,460,937,500 | 53,510.2739726027 | | ≤ 2,480,468,750 | 26,755.1369863014 | …etc. This continues on forever. 85% of esXAI emissions support the essential work of Sentry Keys, ensuring the network's integrity. A remaining 15% is allocated to a gas subsidy node which is used to help create a gasless experience for players, thereby decreasing friction on chain and likely increasing transaction volume. {% hint style="info" %} * Review the [**open initiatives**](/xai-network/about-xai/open-initiatives/xai-protocol-initiatives) to see when this functionality is available. * The first halving event took place on: 05/22/24. {% endhint %} # Network Rewards Network Rewards are issued for the previous Challenge's Assertions approximately every hour when the next Challenge is created. The total network reward amount will be calculated based off of the emission schedule and time in seconds since the last Challenge. To calculate this you use the following formula ((daily emission rate)/(86400 seconds in a day)) \* (seconds since last challenge) = total network rewards for the challenge Although the total network Reward for each Challenge is fixed by the emission schedule, the division of the Network Reward amongst the operational and participating Sentry Keys depends on a number of factors: the total supply of XAI and esXAI, the number of keys that are operating for a given Challenge, and the reward tier of those keys. When determining the total supply, please keep in mind the following; 1. The combined total of XAI and esXAI will never exceed 2,500,000,000. Given the Xai ecosystem is dynamic, accurately predicting monthly token reward per operational Sentry Key is not possible. 2. 100% of gas is burned, so it is not guaranteed that the supply will always be inflationary; it may experience periods of deflation. When determining the number of keys that are operating, please keep in mind the following; 1. The total number of Sentry Keys. The Xai Foundation will not sell more than 5,000,000 Sentry keys. This is expected to take 2-3 years. The price per Sentry key will increase over time. 2. The monthly quantity of esXAI per Sentry Key will fluctuate based on the number of keys that are being operated by a Sentry Node and the reward tiers of those keys. When determining the reward tier of Sentry Keys, please keep in mind the following: 1. Each Sentry Key has a 0.01% percent probability of participating in a Challenge, therefore some Sentry Keys will generate no rewards from each given Challenge. 2. The probability that a Sentry Key will participate in a Challenge can be increased by Staking (refer to [Staking Explained](/xai-network/staking-explained)). 1. If a wallet has a v1 stake, the Reward Tier applicable to any unstaked keys in the wallet will be determined by the lower of (a) the staking capacity of all the unstaked keys in the wallet or (b) the v1 stake. 2. If keys are staked in a pool, that pool's Reward Tier will apply to all keys staked in the pool. The pool's Reward Tier is determined by the lower of (a) the pool's esXAI staking capacity, or (b) the esXAI staked in the pool. All Sentry Keys that participate in a Challenge will receive a pro-rated equal share of the Network Reward. {% hint style="info" %} * Read more about how the total supply affects daily emissions in the section [XAI & esXAI Emissions & Burning](/xai-network/about-xai/xai-tokenomics/xai-and-esxai-emissions-and-burning). * Sentry key owners should prepare to stake their rewards to maintain or improve their monthly rewards. {% endhint %} # Sentry Key Pricing Tiers Sentry Key sales will be priced based on tiers with a quantity of keys allocated for each pricing tier. Below is a table that displays each tier, the number of keys in that tier, and the cost in ETH to purchase a key in that tier. Once a tier has sold out its allocation the smart contract will implement the new price for the current tier. In December of 2024 a 1:100 split was implemented to increase the supply by 100x and reduce price by 100x. This allowed keys to be more accessible to users. This resulted in Tier 18 being split in two parts, sales before the split and sales after.

**Max XAI Supply**: 2,500,000,000 **Total Sentry Keys**: 5,000,000 # Sentry Keys Explained The Sentry Node is an observation node that monitors the Xai rollup protocol and if an incorrect block is proposed, it raises an alarm (by whatever means its operator chooses) so that others can intervene. The purpose of Sentry nodes is to solve the [verifier’s dilemma](https://medium.com/offchainlabs/cheater-checking-how-attention-challenges-solve-the-verifiers-dilemma-681a92d9948e). Sentry nodes can be run on community members’ laptops, desktops or even on cloud instances. A Sentry Key or Keys are what enable network rewards for running a Sentry Node. A single Sentry Node instance can operate any number of Sentry Keys resulting in one instance generating rewards for unlimited keys. As long as the node is running, there is a probabilistic algorithm that determines if the node operator will receive a esXAI token reward from the network for their Sentry Keys. That algorithm can be increased by staking esXAI. Pool operators run Sentry Nodes for all Sentry Keys staked in their pools. This allows Sentry Key holders to earn rewards without having to operate a Sentry Node. # How do Sentry Nodes Work The Attention challenges v2 protocol involves several actors including the Xai chain, a parent chain (Arbitrum One), a trusted Challenger, the Xai Sentries and their license key, and a Referee contract. The Challenger creates a BLS key-pair, registers the public key with the Referee, and signs assertions made by validators in the Xai rollup protocol on Arbitrum One. These signatures are verified by the Referee and recorded as challenges associated with the assertions. Xai Sentries can register with the Referee by purchasing a Sentry Key to be eligible to post claims with respect to an assertion. They get the state root of the correct assertion that will be the successor of a posted assertion, and if a certain condition is met, they post a claim on the assertion by calling the Referee. If a successor assertion is created and confirmed, and the Sentry posted a correct claim, the Sentry contacts the Referee to post a redeem transaction. The Referee verifies several conditions before paying a reward to the Sentry. The protocol ensures that each assertion must consume exactly the inbox messages that existed when its predecessor assertion was created. This means that as soon as an assertion is created, the state root of its correct successor assertion is fully determined, and can be calculated by any node. This incentivizes each Sentry to determine the correct next state root. The reward for a Sentry depends on the Sentry's state license ID, the successor state root, and a challenge value that does not become known until after the successor state root is fully determined. # Who Can Operate A Sentry Node Anyone can operate a sentry node by downloading the software, installing it, and running it. However, to accrue rewards, at least one Sentry Key must be purchased. Rewards are claimed in the non-transferable token esXAI. esXAI can be redeemed for XAI. To claim XAI redemptions, key holders must successfully pass a KYC check that confirms two conditions: a) they are not in the USA, and b) they are not subject to any OFAC sanctions. If you would like to know if you are subject to OFAC sanctions, you can review the OFAC website [here](https://ofac.treasury.gov/). KYC screening will be conducted by Blockpass. [Blockpass](https://www.blockpass.org/) is leveraged by projects like Polygon, Chainlink, Cardano, Animoca and many others in the industry. When you purchase a Sentry Key, you must also confirm that doing so does not violate any local laws which you are subject to.\ \ Sentry nodes that are not running or not properly funded to pay for gas fees do not accrue rewards, even with a Sentry key. Therefore, operators will want to ensure that their nodes are funded, online and running. {% hint style="info" %} * Challenges can be missed in the event of a significant update. These updates will be announced in [Discord](https://discord.gg/xaigames) ahead of time. * Node operators may be required to update their software to keep the nodes running {% endhint %} # Referee Smart Contract The Referee Smart Contract is a crucial component in the Xai ecosystem. It is responsible for managing and validating assertions made by the Sentry Nodes in the network. The contract has several key functionalities: * submission of assertions * claiming rewards * creating assertion hash and checking payout # Submission of Assertions The contract allows Sentry Nodes to submit assertions to a challenge. This function can only be called by the owner of a Sentry Key or addresses they have approved on this contract. The function checks if the challenge is open for submissions and if the Sentry Key hasn't already been submitted for this challenge. # Claiming Rewards The contract includes a function that allows a user to claim a reward for a successful assertion. This function checks if the challenge is closed for submissions. If this condition is met and the assertion is valid for a payout, a reward is sent to the user. # Creating Assertion Hash and Checking Payout The contract has a function that creates a hash of the Sentry Key ID, challenge ID, challengerSignedHash from the challenge, and the successor state root. It then checks if the hash is below a certain threshold, which is calculated based on the total number of Sentry Licenses that have been minted. If the hash is below the threshold, the assertion is valid for a payout. The Referee contract ensures the integrity of the Xai network by validating assertions and rewarding successful ones, thereby incentivizing Sentry Nodes to monitor the network accurately and diligently. # Challenger Component The Challenger is a trusted entity in the Xai ecosystem. It creates a BLS key-pair and registers the public key with the Referee. When an assertion is made by a validator in the Xai rollup protocol, the Challenger signs the assertion with its private key and submits the signature to the Referee. The Referee verifies the signature and records it as a challenge associated with the assertion. This process ensures the integrity of the assertions made in the Xai rollup protocol. # Key (NFT-based) The Sentry Key is a unique, non-fungible token (NFT) that is required to operate a Sentry Node in the Xai network. The Sentry Key serves as a proof of eligibility for a node to submit claims and receive rewards. It is minted by sending the correct amount of Ether or equivalent value in fiat or other ERC20 currencies that the mint contract accepts, and the price for minting is determined by an increasing threshold system. The Sentry Key plays a crucial role in the Referee contract. When a node wants to submit an assertion to a challenge, it must provide its Sentry Key ID. The Referee contract checks if the Sentry Key is valid and if the node is either the owner of the Sentry Key or an approved operator. If these conditions are met, the key's assertion is submitted to the challenge. When the next challenge occurs the Referee contract will make rewards available for Sentry Keys that submitted assertions for the previous challenge. In summary, the Sentry Key is a key component in the Xai network that regulates the operation of Sentry Nodes, the submission of assertions, and the distribution of rewards. # Sentry Download and Operation To operate a Sentry, users need to download and use a Core library. This library is utilized in both a Command Line Interface (CLI) application and a desktop application. These applications serve as wrappers for the Sentry software supplied by the Core library. The Core library is designed to automate all the necessary steps to run a Sentry. It simplifies the process of setting up and running a Sentry, making it accessible for users with varying levels of technical expertise. The Core library handles tasks such as setting up the Sentry environment, managing node operations, and interacting with the Referee. It also provides a user-friendly interface for monitoring node status and managing node settings. By using the Core library, users can focus on the strategic aspects of operating a node, such as optimizing their node's performance and maximizing their rewards. The primary method for running the Core library is through the Desktop client or the CLI. Both of these are designed to be user-friendly and provide a seamless experience for operating a node. # Sentry Wallet Functionality In the Xai ecosystem, a Sentry Wallet plays a crucial role in the interaction between the Sentry Nodes and the Referee Smart Contract. The Sentry Wallet acts as an intermediary agent responsible for submitting assertions to the Referee on behalf of the associated Sentry. This is facilitated through specific functions in the Referee contract that can only be called by the owner of a Sentry Key or addresses they have approved on this contract. The Sentry Wallet can submit an assertion to a challenge by calling the \`submitAssertionToChallenge\` function in the Referee contract. This function checks if the challenge is open for submissions and if the Sentry Key hasn't already been submitted for this challenge. If these conditions are met, the sentry's assertion is submitted to the challenge. The Sentry Wallet can also claim a reward for a successful assertion by calling the \`claimReward\` function in the Referee contract. This function checks if the challenge is closed for submissions. If this conditions is met and the assertion is valid for a payout, a reward is sent to the Sentry owner. In summary, the Sentry Wallet serves as a messenger facilitating the interaction between the node and the Referee, thereby ensuring the smooth operation of the Xai network. # Licensing Impact A Sentry Node is able to operate Sentry Keys on a single machine. Previously, putting more keys on a singular node does increase the amount of throughput that your computer will need for the Sentry, including the hashing of submissions and submitting claims to the chain. However this has since been optimized to eliminate any additional operational requirements at scale. # Sentry Node Hardware Requirements The Sentry Node software supports Windows Desktop, Mac, and Linux (64-bit required). These are the current resources required for running the Sentry Node Software with up to 100 license keys:\ \ **4 GB RAM**\ **2 CPU Cores** \ **60 GB Disk Space**\ **x86/X64 Processor**\ **Stable Internet Connection** When incorporating additional keys into your node, it is expected that the hardware prerequisites will also see an escalation. However, it is not mandatory to allocate a separate machine for each key. The system's scalability is anticipated to accommodate dozens of keys on a single machine, and potentially even more. \ The Sentry Node Software supports ARM Processors like the Apple M1/M2 chips.\ \ These requirements are subject to change. # Sentry Node Utility ## Sentry Node Operations: Pre and Post V2 BOLD Update on Xai Blockchain Xai blockchain's infrastructure, currently leveraging Arbitrum’s Nitro Rollup Contracts, is poised for a significant evolution with the upcoming V2 BOLD update from Arbitrum. This transition marks a pivotal shift in the functionality of the Sentry Nodes within the Xai ecosystem, especially in terms of security and proactive error detection. {% hint style="info" %} * The code and specification for Offchain Labs' BOLD (Bounded Liquidity Delay) is available on [**Github**](https://github.com/OffchainLabs/bold). * Read more about BOLD protocol and roadmap [**here**](https://medium.com/offchainlabs/bold-permissionless-validation-for-arbitrum-chains-9934eb5328cc). * Details regarding v2 BOLD will be available in the near future. {% endhint %} ### Pre-V2 BOLD Update Scenario: In the current state, the Challenger, a critical component in our system, retrieves the State Root from the Rollup Protocol. Simultaneously, the Nitro Nodes, responsible for supplying this State Root, also receive the same data. The primary function of the Sentry Nodes, in this setup, is to ensure the integrity of the State Root as submitted to the Rollup Protocol. A crucial limitation, however, is the Sentry's inability to foresee the State Root. This reactive approach means that Sentry Nodes act more like traditional digital detectives, verifying the State Root only after it has been committed. Think of this as the conventional crime-fighting approach in a digital realm – the Sentry Nodes investigate and flag an error (akin to a crime) only after it has occurred. They are effectively working post-event, detecting and raising an alarm when issues make their way into the system. ### Post-V2 BOLD Update Scenario: The V2 BOLD update introduces a paradigm shift. While the Challenger continues to receive the State Root from the Rollup Protocol, the Nitro Nodes gain a significant enhancement – the ability to predict the next State Root before the completion of the current challenge. This prediction is synchronized with the closure of the Challenger's current challenge and the submission of the new State Root. This advanced capability dramatically elevates the security posture of Xai blockchain. We transition from reactive to proactive error detection. The Sentry Nodes, equipped with this foresight, can now identify and address improper State Roots before they are even submitted to the Rollup Protocol. It’s akin to having a 'precognitive' ability, reminiscent of the 'precogs' in the science fiction classic, "Minority Report". To elaborate, in the movie, 'precogs' are individuals with the gift to foresee crimes before they happen, allowing law enforcement to prevent them proactively. Analogously, in our Post V2 BOLD update scenario, our Sentry Nodes assume the role of these 'precogs', gaining the ability to 'see' potential issues (improper State Roots) before they materialize in the Rollup Protocol. This is a monumental leap from the traditional 'after-the-fact' approach to a more advanced, predictive security measure, ensuring a robust and preemptively secure blockchain environment. # Accruing Key Rewards * To accrue key rewards, a Sentry Key must participate in a Challenge. * A Challenge is created approximately once every hour. This means there will be \~720 Challenges per month. * Each Sentry Key that participates in a Challenge will receive a pro rata share of the Network Reward, as described in [Network Rewards](/xai-network/about-xai/xai-tokenomics/network-rewards). * By default, each Sentry Key has a 0.01% probability of participating in a Challenge. This is known as the Bronze Tier. * The probability that a Sentry Key will participate in a Challenge will increase if the Key is staked in a Pool with higher Tier than Bronze. Each Reward Tier is explained in the section, [Staking Rewards and Tiers](/xai-network/staking-explained/staking-rewards-and-tiers). * To maximize the potential of earning Network Rewards from a Sentry Key, it is strongly recommended that you participate in a Pool and run the Sentry Wallet (a.k.a. Operator) 24 hours a day, 7 days a week. # Sentry Key Purchase & Setup This section provides an in-depth guide on how to purchase Keys to run a Xai Sentry Node and how to setup the node to generate rewards.

Make sure to select **Ubuntu 22.04** as your Operating System. The location of your VPS has no influence on whether you can pass the KYC or claim rewards. Here are some VPS options (prices may vary based on your location and the plan you choose): * [Racknerd](https://www.racknerd.com/) * [Hostwinds](https://www.hostwinds.com/) * [Digital Ocean](https://www.digitalocean.com/) After your purchase, you’ll receive login details in your email. # Step 2: Log in to a server Follow these steps on on your laptop/PC: 1. Open a terminal window on your laptop or PC to enter commands {% hint style="info" %} * On Windows, open the program called Command Prompt. * On Mac, open the program called Terminal. {% endhint %} 2. To connect to VPS, use the `ssh` command from your terminal: 
ssh $USER@$REMOTE_SERVER
Example: ``` ssh root@706.437.14.562 ``` {% hint style="info" %} If you’re using Windows, the SSH Client is available starting from [Windows 10](https://docs.microsoft.com/en-us/windows-server/administration/openssh/openssh_overview) version. For earlier versions, please use [PuTTY](https://www.putty.org/) or other alternatives. {% endhint %} 3. When you log in the first time, you’ll see the following message: ``` The authenticity of host '$REMOTE_SERVER' can`t be established. ED25519 key fingerprint is SHA256:... This key is not known by any other names. Are you sure you want to continue connecting (yes/no/[fingerprint])? ``` Type `yes` and press `Enter`. This will prompt you to input a **password**. Note, all Linux systems don’t reveal passwords when you type them. Finish entering your password and click `Enter`. {% hint style="info" %} If your credentials are correct, you will see the following message: ``` Warning: Permanently added '$REMOTE_SERVER' (ECDSA) to the list of known hosts. root@$REMOTE_SERVER`s password: Welcome to Ubuntu 20.04.6 LTS (GNU/Linux 4.4.0-169-generic x86_64) * Documentation: https://help.ubuntu.com * Management: https://landscape.canonical.com * Support: https://ubuntu.com/advantage 0 packages can be updated. 0 updates are security updates. ``` {% endhint %} {% hint style="success" %} Going forward, any time you want to log in to your VPS via the terminal, enter the command: 
ssh $USER@$REMOTE_SERVER
{% endhint %} # Step 3: Set up Xai Sentry Node 1. Ensure your system is up to date by running the following command: ``` sudo apt update ``` 2. Install the required dependencies, `curl` and `unzip`, using the following command: ``` sudo apt install curl unzip ``` 3. Fetch the latest version of the Xai Command Line Interface (CLI) using `curl`: ``` curl -L -o sentry-node-cli-linux.zip https://github.com/xai-foundation/sentry/releases/latest/download/sentry-node-cli-linux.zip ``` 4. Unzip the file: ``` unzip sentry-node-cli-linux.zip ``` # Step 4: Set up a Screen [Screen](https://www.gnu.org/software/screen/manual/screen.html) will allow you to keep running the CLI even if you’re disconnected or you log out from your server. 1. Install screen: ``` sudo apt update && sudo apt install screen ``` 2. Start a screen session: ``` screen -S xai ``` {% hint style="info" %} This will open a screen session, create a new window, and start a shell in that window. The first time you start a screen, you’ll see a page of license information. You can press the `Space` bar to read the second page or `Enter` to return to the command prompt. To verify that you set up a Screen session, type `screen -ls` in a second terminal. You should see a message that looks as follows: ``` There is a screen on: 82824.xai (12/09/2023 11:04:52 AM) (Attached) 1 Socket in /run/screen/@root. ``` {% endhint %} # Step 5: Start Xai Sentry Node 1. Now that you set up a Screen, you can start Xai CLI: ``` ./sentry-node-cli-linux ``` 2. To receive node rewards, boot your operator: ``` boot-operator ``` 3. This will prompt you to enter the private key of your **sentry wallet**. Paste the key and press `Enter`. 4. Wait a few minutes until you see the following message: ``` The operator has finished booting. The operator is running successfully. esXAI will accrue every few days. Current timestamp: 2023-12-10T01:47:04.273Z. The operator is still running successfully. esXAI will accrue every few days. ``` 5. Detach from your Screen session before logging out. You can detach from your current Screen session by **pressing**: * `ctrl a + d` (Windows) * `control a + d` (macOS) or ``` screen -d ``` where `` is the numbers of your Screen session. Example: ``` screen -d 82824 ``` {% hint style="info" %} Make sure to **Detach** before exiting the server. Detached mode allows you to exit your Screen session without closing or interrupting any processes that are happening within that session. That means that everything will keep running in the background even if you log out from your VPS. {% endhint %} 6. You can now safely log out from your server: ``` logout ``` # Step 6: Monitor your Node via Screen ### Show all Screen sessions To see all Screen sessions, type `screen -ls` . You should see a message that looks as follows: ``` There is a screen on: 82824.xai (12/09/2023 11:04:52 AM) (Detached) 1 Socket in /run/screen/@root. ``` ### Kill/Delete a Screen session If you have multiple Screen sessions, you can kill the one you don’t need as follows: ``` screen -XS quit ``` > Replace the following values:\ > -`` - the id of your current Screen session\ > -Example: `screen -xs 82824 quit` ### Reattach to your Screen session Anytime you want to see the logs from your node, you can reattach to that session as follows: Comment ``` screen -r ``` where `` is the numbers of your Screen session. Example: ``` screen -r 82824 ``` Note, currently you can’t see the rewards using the CLI. You need to install a desktop app for it. For more details refer to [this video](https://xai-foundation.gitbook.io/xai-network/xai-blockchain/sentry-node-purchase-and-setup/how-to-videos/command-line-interface-cli/track-accrued-esxai). ### Detach from your Screen session You can detach from your current Screen session by **pressing**: * `ctrl a + d` (Windows) * `control a + d` (macOS) or ``` screen -d ``` where `` is the numbers of your Screen session. Example: ``` screen -d 82824 ``` Make sure to **Detach** before exiting the server. Detached mode allows you to exit your Screen session without closing or interrupting any processes that are happening within that session. That means that everything will keep running in the background even if you log out from your VPS. You can now safely log out from your server: ``` logout ``` # Step 7: Updating your node Following these steps will help you set up and maintain your Xai Sentry Node effectively. Remember to regularly check for updates and monitor your node’s performance. 1. Login to your server using the `ssh` command from your terminal: ``` ssh $USER@$REMOTE_SERVER ``` 2. Reattach to your Screen session: ``` screen -r ``` 3. Replace the following values:\ \- `` - the id of your current Screen session\ \- Example: `screen -r 82824` 4. Stop the operator: * `ctrl + c` (Windows) * `control + c` (macOS) 5. Remove your current CLI: ``` rm sentry-node-cli-linux sentry-node-cli-linux.zip ``` 7. Download the latest CLI. You don't need to download the file on your computer since this command takes it from the GitHub website. ``` curl -L -o sentry-node-cli-linux.zip https://github.com/xai-foundation/sentry/releases/latest/download/sentry-node-cli-linux.zip ``` 8. Unzip the file: ``` unzip sentry-node-cli-linux.zip ``` 9. Start CLI: ``` ./sentry-node-cli-linux ``` 10. Boot the operator: ``` boot-operator ``` 11. Paste the private key of your **Sentry Wallet** and press `Enter`. 12. Wait until the operator has finished booting and you see the following message: ``` The operator has finished booting. The operator is running successfully. esXAI will accrue every few days. Health check complete, subscription to 'ChallengeSubmitted' is still active. ``` 13. Detach from your Screen session: * `ctrl a + d` (Windows) * `control a + d` (macOS) 14. Logout from your server: ``` logout ``` {% hint style="info" %} To KYC and view rewards, you need the desktop app, which is not covered in the CLI. {% endhint %} # How do I prevent others from using my Sentry Wallet or Operator? {% tabs %} {% tab title="Desktop App" %} As of update v1.0.33, a Sentry Wallet owner can determine what wallets it operates on.
