XeChain is a next-generation Proof-of-Work (PoW) EVM Layer 1 blockchain designed with a laser focus on GPU mining, high throughput, and robust security. Our central goal is to empower miners of all sizes and backgrounds by implementing an ASIC-resistant algorithm (XeHash), preventing specialized hardware from dominating the network. By maintaining 5-second block times, handling up to 1900+ TPS, and employing EIP-1559-based fee burning alongside a 200M+ gas limit, XeChain prioritizes accessibility, scalability, and decentralization in equal measure, making it an ideal platform for the rapidly expanding universe of decentralized applications (dApps).
In addition, XeChain offers a deeply developer-friendly EVM environment, ensuring a smooth transition for builders familiar with existing Ethereum tools. By coupling cutting-edge GPU optimization with energy-efficient validation and rapid block times, we believe XeChain sets a new benchmark in Proof-of-Work blockchain capabilities. This whitepaper outlines our technological choices, tokenomics, and strategic roadmap, showcasing how XeChain aims to redefine decentralization and performance for the next wave of global crypto adoption.
Blockchain technology has undergone dramatic evolution since the launch of Bitcoin, with numerous projects emerging to tackle various limitations related to speed, cost, and network security. Yet, the challenges of ASIC-dominated mining—where specialized machines outcompete regular miners—continue to pose significant risks to blockchain decentralization. Miners with specialized hardware can gain a disproportionate share of rewards, creating centralization pressure and potentially destabilizing the network.
XeChain addresses these issues head-on by building an ecosystem that leverages the power of ubiquitous GPU hardware. By optimizing our consensus mechanism to rely on floating-point operations, we substantially level the playing field for everyday participants. Moreover, our fast block times and large block sizes enable the network to handle high transaction volumes, supporting the needs of modern DeFi, NFT platforms, and other data-intensive use cases. Through a fair emission schedule and EVM compatibility, XeChain aims to empower a vibrant community of miners, developers, and users.
XeChain solves these challenges by adopting a GPU-oriented mining algorithm, enabling high throughput to accommodate modern applications, ensuring a consistent developer experience through EVM compatibility, and embracing a wide variety of GPU setups to maximize accessibility. Our approach seeks to reinvigorate Proof-of-Work with an emphasis on genuine decentralization and a focus on long-term network resilience.
By addressing each of these pressing issues, XeChain aspires to provide a robust, equitable, and future-ready blockchain platform. Our vision of an inclusive PoW network recognizes the importance of fair entry points, developer convenience, and a scalable ecosystem where all participants can benefit.
At the heart of XeChain’s design is the XeHash algorithm, derived from Cryptonight-GPU, which heavily employs FP32 math. GPUs inherently excel at floating-point operations due to their architecture, making them ideal for XeHash. Conversely, ASICs and FPGAs do not gain significant advantages in this area, thereby minimizing the risk of specialized hardware dominating the network.
This approach democratizes mining, allowing widespread GPU owners—ranging from hobbyists with a single card to more experienced participants—to join on near-equal footing. Our dedication to GPU optimization paves the way for a more vibrant community, united by the principle of fair access to mining rewards and network influence.
XeChain aims to surpass the scalability constraints of many traditional PoW networks by supporting a 5-second block time and a 200M+ gas limit. By accelerating block confirmations, we enable a faster, more fluid user experience—vital for DeFi services, real-time gaming, and large-scale NFT marketplaces. Our throughput consistently reaches 1900+ TPS under optimal conditions.
This high-performance threshold ensures that applications built on XeChain can handle demand spikes without crippling transaction fees or extended wait times. Our architectural choices are designed for adaptability, positioning the blockchain to respond effectively as technology and user demands continue to evolve.
Rather than forcing developers to adopt new programming languages or frameworks, XeChain is fully EVM-compatible. This strategic choice empowers developers to seamlessly bring existing smart contracts and dApps from Ethereum or other EVM-based networks. Popular tools like Solidity, Remix, Truffle, and Hardhat translate directly into XeChain’s environment, minimizing any friction in the migration process.
By retaining Ethereum’s development tooling, XeChain lowers the barriers to entry for new projects and shortens time-to-market for existing ones. Our goal is to cultivate a thriving developer ecosystem where innovative dApps can take root and flourish, benefitting from faster confirmation speeds and more equitable mining mechanics.
A high gas limit coupled with optimized block propagation techniques allows XeChain to handle a larger volume of transactions without incurring excessive fees. This is particularly critical for DeFi platforms, which rely on complex on-chain operations such as lending, swaps, and margin trading. By keeping transaction costs consistently low, XeChain encourages more user activity and fosters an environment where large-scale adoption remains feasible.
Additionally, our network design ensures that scaling improvements do not come at the expense of security or decentralization. We carefully calibrate block capacity to balance efficiency with network stability. As a result, participants can rely on XeChain to maintain a reliable, cost-effective infrastructure that empowers a wide range of applications.
XeChain’s reliance on GPU-based Proof-of-Work naturally disperses hashpower among participants globally, mitigating the risk of 51% attacks. By preventing a small group of specialized devices from capturing the majority of the hashpower, XeChain safeguards its network’s integrity and keeps control distributed among many nodes.
We further bolster security through robust block propagation mechanisms, in-depth audits, and continuous community-led testing. Ultimately, XeChain’s architecture champions decentralization as a foundational principle, recognizing it as an essential feature for maintaining both short-term resilience and long-term trust.
https://rpc.xescan.net/XeChain’s emission schedule reflects our commitment to a fair launch and a transparent supply distribution. By setting staggered block rewards, we encourage early miners to help secure the network while gradually reducing inflation over time. This structure not only supports initial enthusiasm but also fosters long-term stability, ensuring that XE remains scarce and valuable as the ecosystem matures.
New blocks are minted every ~5 seconds, distributing rewards among GPU miners. Because mining is accessible to a broad range of participants, the emission schedule helps promote a balanced and healthy network, where no single entity can rapidly amass an overwhelming proportion of the total supply.
| Block Range | Block Reward (XE) |
|---|---|
| 1 – 500,000 | 100 XE |
| 500,001 – 1,000,000 | 50 XE |
| 1,000,001 – 2,000,000 | 25 XE |
| 2,000,001 – 5,000,000 | 10 XE |
| 5,000,001 – 75,000,000 | 1 XE |
Max Supply: 200,000,000 XE
Mining Duration: ~11 years to reach maximum supply
Each block reward includes a 20% development fee dedicated to ongoing project growth, marketing, exchange listings, and vital resources that ensure XeChain’s success. This consistent funding stream allows the core team to enhance user experience, maintain infrastructure, and implement updates without relying on external fundraising.
This fee model is transparent and predictable, aligning developer incentives with community needs. By aligning the project’s fortunes with the network’s overall health, we promote sustained innovation and responsiveness within the XeChain ecosystem.
XeChain had no premine or presale, underscoring our commitment to equal opportunity for all participants. Early and late miners alike can obtain XE solely through Proof-of-Work mining or secondary markets. This approach solidifies our stance that blockchain success should be determined by active contribution rather than privileged early access or insider allocations.
The decentralized distribution further enables grassroots growth, allowing each new participant to become an integral part of the community. As more miners join, network security and resilience increase, forging a feedback loop that perpetuates a truly decentralized ledger.
