Dear XDB CHAIN Community Members, We are excited to announce the commencement of the launch of XDB CHAIN V19 Mainnet set to begin today. This launch represents a pivotal moment in XDB CHAIN blockchain’s development, bringing enhanced features and benefits to our valued community. 1. Network Upgrade ScheduleThe upgrade process on XDB CHAIN begins shortly today and will extend to participating exchanges starting tomorrow. We anticipate the completion of this activity within 48–72 hours. Our team has worked diligently to ensure a smooth and efficient upgrade process. 2. Hassle-Free for XDB Token HoldersWe have designed this upgrade to be seamless for XDB token holders. There is no requirement for any action on the holder’s part during the maintenance window, whether you hold your tokens on AstraX or any of the participating exchanges. Holder’s balances will remain intact and secure throughout this process. 3. Airdrop of XDB CHAIN Native CoinsXDB token holders will receive XDB CHAIN native coins airdrop on a 1:1 basis for the tokens they currently hold on the Digitalbits network. Following the completion of this activity, a burn of 1,000,000,000 XDB CHAIN native coins (XDB) will be performed and shared with XDB CHAIN Community, reducing XDB token supply accordingly 4. Easy Balance Check on New XDB CHAIN ExplorerUpon completion of the launch of XDB CHAIN, XDB holders will be able to immediately verify their balances on the XDB CHAIN network through the new explorer. Rest assured, both public and private keys will remain unchanged, ensuring a seamless transition to the new network. 5. Focused Support for XDB CHAIN NetworkMoving forward, the XDB Foundation’s support will be exclusively for the XDB CHAIN Network, token holders on this network, and the stakeholders actively participating in the XDB CHAIN Governance. This focused approach will enable this project to deliver more targeted and effective support, furthering the growth and success of the XDB CHAIN. 6. Transitioning from Digitalbits NetworkAs this project and its community advance with the XDB CHAIN, the XDB Foundation will gradually phase out support for the Digitalbits network and its infrastructure over the next 90 days. 7. AstraX Users: Action Required Post-UpgradeOnce the maintenance is completed and following the release of the new XDB CHAIN non-custodial XDB Wallet, all non-custodial holders (such as AstraX users) will need to export their private keys and re-import them into the new XDB Wallet. This export must be completed within 90 days as per above, it is not required for those who have already exported their private keys. This step is crucial for managing holder’s XDB CHAIN coins on the new non-custodial wallet. Please note, AstraX is not compatible with the XDB CHAIN Network and cannot be used for this purpose. Your old XDB Digitalbits coins will remain on Digitalbits holder’s wallet, under holder’s custody, until the network ceases to function. 8. Participating exchanges and XDB token metric’s trackingUpon the successful completion of the maintenance activities, participating exchanges will exclusively handle the deposits and withdrawals of the new XDB CHAIN native coins on the XDB CHAIN Network. They will cease support for the old XDB coins on the Digitalbits network, and they will no longer monitor or manage any activities related to them. Similarly, token tracking websites (CoinMarketCap, Coingecko) will now exclusively reference the XDB CHAIN native coin, XDB, along with its updated supply details and tokenomics from now onwards. Stay ConnectedWe encourage you to stay tuned to our official channels for continuous updates throughout the upgrade process. We are here to support and guide you through this exciting transition. Thank You for Your Continued SupportYour trust and commitment to the XDB CHAIN project are invaluable. We look forward to embarking on this new chapter together, further enhancing the XDB CHAIN and its community.

Article is updated upon the release of XDB CHAIN v19 BURN of 1,000,000,000 XDB CHAIN native coins IntroductionIn the ever-evolving world of cryptocurrencies, innovation is the key to success. One such innovation that has been gaining traction in recent times is the concept of burning tokens to introduce digital scarcity. Following the introduction of the unique value proposition of Branded Coins (BCO) which brings its unique buyback and burn mechanism (BBB), XDB Chain aims to improve the real-world utility and the supply-demand value proposition of the XDB coin by leveraging its powerful blockchain platform. This will be progressive rolled out as of the upcoming launch of the XDB Chain Mainnet (v19). The introduction of Branded Coins Offering (BCO) will enable businesses and entities to create their own branded cryptocurrencies on the XDB Chain while supporting the overall ecosystem through an allocation of each new Branded Cryptocurrency supply for regular buyback and burning of XDB coins of up to 2,5% of the entire BCO supply. This mechanism will foster scarcity and provide incentives for all stakeholders such as market participants and token community by strengthening the economic viability and attractiveness of the XDB Chain network as the layer-of-choice. This strategic approach can have profound implications for the supply dynamics and overall value proposition of a cryptocurrency project. In this article, we will explore the benefits of burning tokens in a cryptocurrency supply and how it can be a game-changer in creating digital scarcity. Enhanced Digital ScarcityAt the heart of token burning lies the idea of enhancing digital scarcity. Cryptocurrencies that implement this practice create a sense of rarity and exclusivity around their tokens. Submitting a transaction with zero weights and thresholds invalidates keys, including the master key, thereby preventing any further transactions and token creation. This feature is primarily geared towards developers and can significantly impact the overall supply of the cryptocurrency.Developers can find detailed information on how to utilize this feature in the official XDB Chain documentation, available as of the launch of XDB Chain v19. Reducing Supply and Increasing ValueBurn addresses play a pivotal role in reducing the supply of a cryptocurrency. These addresses can be verified by API users, ensuring transparency in the burning process. Every unit of the cryptocurrency sent to these burn addresses is permanently removed from circulation. This deliberate reduction in supply can have a profound effect on the token’s value. With fewer tokens available, the ones in circulation become more valuable, potentially leading to an increase in price. How Assets are being created on NetworkIn order to distribute a custom asset or token on the XDB Chain network, three unique accounts will be used. First, is the source account. The source account is the account of the entity looking to create a new token. Second is the issuing account. The issuing account is created by the source account as a mechanism to create new tokens. The third account is the distribution account. The goal of a distribution account is to act as the mechanism for distributing tokens to the public. Most of the XDB Chain documentation is centered on financial institutions as anchors. An anchor is an entity that acts as a bridge between existing currencies and the XDB Chain Network, and involves setting up systems like a compliance server and a bridge server. It is not necessary to become an anchor in order to create custom assets and tokens on the XDB Chain Network. The following presents a breakdown of the transactions required to create a custom token. The transactions can be translated to API requests or can be executed using XDB Developer Portal. How the “BURN” address is created (Technical Instructions):Here below, Developers can find the Technical instruction to create a “locked address” which can be used to “burn” tokens, meaning that once transferred will no longer be usable into any future transaction and will be locked forever. Account:Issuing account Operations:Set Option — Thresholds & Weights: remove all weights and thresholds master weight: 0 low threshold: 0 medium threshold: 0 high threshold: 0 Signers: issuing account Transaction A is created and submitted to the network by the issuing account. By setting the weights and thresholds all

“Empowering faster payments with the potential for 1.19 millions transactions per second” Amid the hyper-growth world of blockchain technology, the launch of XDB Chain protocol (v19) marks a key milestone toward bringing the power of web3 to brands and consumers. This release embodies a purpose-driven approach by introducing substantial improvements to the XDB Chain Core, laying the groundwork for the development of Layer 2 solutions that enhance user experience (UX) and enable the tech framework for the mind-blowing payment processing speed of up 1.19 million per second. XDB Chain protocol (v19) is all about enhancing your experience by making payment channels accessible to any use case. These channels are like a high-speed express lane for Brands and Consumers frequent transactions, allowing users to carry out most of the activities away from the blockchain, while keeping track of users’ starting balances and ultimate settlements securely recorded on the blockchain. In the world of payment channels, things work a bit like a well-orchestrated dance. When users and another party kick off a channel, it all begins with an on-chain transaction that gives both control over the accounts. After that, transactions flow between parties, like passing notes in class, and they get checked and approved off-chain to ensure the highest throughput. When one of the parties decides it’s time to wrap things up and settle, it simply announces its intent to close the channel. This action opens a brief window for the other party to voice any concerns. Think of it as having an opportunity to discuss things if there’s a disagreement or if someone’s acting in haste or unfairly. If everything’s smooth sailing, the settlement transaction is sent to the network, marking the final movement of funds on the blockchain. This Layer-2 approach theoretically opens the door to achieving up to 1.19 payments per second with buffering. However, we emphasize the importance of caution in guaranteeing this level of processing in every transaction, and we maintain a conservative stance in this regard by not enabling it yet in the first stage of protocol v19 launch. To this end, we’ve initiated preliminary collaborations with potential enterprise partners to unlock the full potential of processing 1.19 million payments per second. We are currently engaged in rigorous testing of this technology stack and are delving into real-world use cases that extend beyond traditional legacy technologies. While XDB Chain’s easy-to-use multi-signature features have made it simple for people to manage shared accounts, v19 steps in to simplify the complexities involved in the rest of this process. Before this protocol, a transaction would only be considered valid if the source account’s sequence number was precisely one more than the sequence number used in the previous transaction. This constraint prevented the seamless progression of sequence numbers in off-chain channels. What’s more, introducing time delays into transactions was simply not possible, leaving no room for addressing objections or voiding a settlement transaction. Additionally, authorizing transactions by combining signatures required a cumbersome multi-step process, causing delays and operational friction. XDB Chain protocol (v19) resolves these challenges by introducing new preconditions and an innovative type of signer. One of the two first additional improvements introduces a user-friendly set of transaction conditions, allowing you to add special requirements to ensure the safety of your transactions. Imagine these conditions as time limits, ensuring that your transactions are only valid within specific timeframes. With XDB Chain protocol (v19), you can craft transactions that don’t follow a strict sequence, set boundaries for your ledger, introduce delays for added security (we call them “relative timelocks”), and require additional signers, such as hash locks. The real-world value of these conditions shines through in cases like Kaladin, a project making blockchain connections as easy as swapping assets without relying on middlemen. These functionalities will be fully leveraged at a later stage and will be introduced in more details in the coming days. Their innovative solution, built on state channels, an advanced version of payment channels, makes the most of XDB Chain protocol v19’s conditions to add a delay between starting and completing channel closures and to create secure hash time lock agreements that keep asset swaps in perfect sync. The second

With today’s announcement of XDB CHAIN v20 Futurenet and the upcoming XDB CHAIN v19 Mainnet deployment, the XDB Foundation is providing comprehensive community disclosure regarding the transition that has led to the enhancement of the former Digitalbits blockchain vision and the previous governance structure. This transition aims to facilitate the continued growth of the project within the XDB CHAIN ecosystem under renewed governance. As XDB CHAIN embarks on a new trajectory of growth, in collaboration with announced partners who will develop products and applications on it and bring their multi-million user communities, all ecosystem members should expect the highest level of openness, disclosure, and transparency. This document marks the initial step of a new journey, as part of our broader commitment. The primary objective of this disclosure is to address all relevant aspects concerning the tokenomics of the former Digitalbits Blockchain project, which has required some fundamental changes now integrated and openly shared with the XDB CHAIN community. It is vital to acknowledge that this project, in its former vision, encountered various execution challenges. However, the current primary goal is to advance it and continue growing by enabling Technology mass adoption and instilling confidence in partners building on this ecosystem and trusting its remarkable community. Together, we aspire to create a more vibrant and prosperous future with no excuses whatsoever. Over the past few months, the former organizations Fusechain I XDB and Zytara, along with their founder, Al Burgio, have progressively withdrawn support for the Digitalbits Project, as well as any communication and disclosure to the community. Recently, the Digitalbits Foundation, now rebranded as the XDB Foundation, has been diligently working, as evidenced on xdbatlas.com, to redefine an enhanced multi-organizational governance structure to ensure trusted decentralization and a broader network integrity that will continue to support the ecosystem and its community. Every blockchain project requires its governance to be clearly and transparently communicated, and this is foundational as XDB CHAIN moves forward. As a result of this governance change, it is imperative to provide the community with the utmost level of transparency and disclosure regarding the former Digitalbits XDB coin supply. The previous concept and disclosure about the Digitalbits XDB coin’s circulating supply were entirely managed off-chain because no smart contract functionality was ever implemented on the Digitalbits protocol up to this point. Today’s announcement by the XDB Foundation to accelerate support for smart contracts on XDB CHAIN was primarily driven by the need for transparency, with the further goal of providing assurance about the figures reported by the Governance structure as a whole. Transparency without governance is pointless. The value creation of L1 Blockchain Technology derives from its trustless design, which must be embedded in its governance and disclosure processes. Under the assumption above, the native coins of the Digitalbits supply are considered in circulation unless locked by an auditable smart contract or burned into an auditable and permanently locked address. Digitalbits v18 has not implemented smart contracts to date. Therefore, today, all Digitalbits XDB native coin token metrics are as follows: Digitalbits Mainnet v18 MAX TOKEN SUPPLY: 20,000,000,000 TOTAL TOKEN SUPPLY: 19,974,370,019.97 CIRCULATING SUPPLY: 19,974,370,019.97 As part of the transition from Digitalbits v18 to XDB CHAIN v19 and in alignment with this new governance structure, the XDB Foundation commits to reducing both the total supply and circulating supply by 1,000,000,000 XDB CHAIN native coins. This will be executed following the completion of XDB CHAIN Mainnet v19 upgrade. XDB CHAIN Mainnet v19 MAX TOKEN SUPPLY: 20,000,000,000 TOTAL TOKEN SUPPLY: 18,974,370,019.97 CIRCULATING SUPPLY: 18,974,370,019.97 BURNED COINS: 1,025,629.980.03 Nevertheless, the XDB CHAIN Project’s commitment, beyond the immediate 1,000,000,000 XDB CHAIN native coin burn upon XDB CHAIN Mainnet v19 launch, is to commence quarterly burns starting Q1 2024, to further reducing both the total and circulating supply of XDB CHAIN to get to 10,000,000,000 billion coins through auditable and transparent communication and disclosure processes. The project’s growth will primarily hinge on the launch of multiple BCO (branded coins) and brand’s payment integration, some of which have already been announced and will commence shortly. Additionally, for the sake of transparency, the XDB Foundation proactively discloses the holdings of the following Digitalbits XDB coins that are considered as in circulation, as per the
