What is Sirius Chain (XPX)?
Sirius Chain is a blockchain-based infrastructure platform developed as part of the ProximaX ecosystem. It is designed to provide an enterprise-grade solution that integrates traditional blockchain features with distributed service layers such as storage, streaming, and database management. Originally built as a fork of the NEM blockchain technology, Sirius Chain has been modified to support a wider range of decentralized applications and enterprise services. The project emphasizes a holistic approach to decentralized services. Rather than operating solely as a ledger for transactions, it functions as an all-in-one platform for developers to build applications without needing to manage separate decentralized storage or messaging protocols. Key technological components include its Supercontract feature, which provides enhanced smart contract capabilities, and its distributed file management system. The native utility token of the network is XPX. Within the ecosystem, this token serves several primary functions. It is used to pay for transaction fees on the network and is required for users to access and subscribe to various platform services like data storage and streaming. Additionally, the token is used for network security through a staking mechanism. Participants can stake their tokens to help validate transactions and secure the chain, a process often referred to as harvesting. Sirius Chain supports various network configurations, including public, private, and hybrid setups. This flexibility allows businesses to maintain privacy for sensitive data while still benefiting from the transparency and security of blockchain technology. The platform also includes built-in features such as multi-level multisignature accounts, cross-chain transaction capabilities, and tools for creating digital assets or non-fungible tokens. By providing a comprehensive set of software development kits and application programming interfaces, the project aims to simplify the deployment of complex decentralized solutions for industries ranging from finance to supply chain management.

Sirius Chain (XPX) FAQ
Sirius Chain is the rebranded identity of the ProximaX project. While the brand has evolved to reflect a broader focus on a comprehensive Web3 and DeFi ecosystem, the native token ticker remains XPX. The project has expanded from its origins as an enterprise storage solution into a platform that integrates decentralized storage, streaming, and database services within a single blockchain framework, built on technology improved from the NEM blockchain.
XPX primarily serves as the native utility token used for transaction fees and network harvesting. However, recent developments in the ecosystem have introduced a decentralized stablecoin protocol. This allows users to use their XPX utility tokens as collateral to mint stable assets. While the core XPX token provides utility, the protocol enables the creation of debt-backed stablecoins to facilitate various activities within the Sirius DeFi landscape.
XPX offers several core utilities within the Sirius Chain ecosystem. Users can participate in 'harvesting' to validate transactions and secure the network. Additionally, tokens can be staked in the Stability Pool to support decentralized finance protocols and earn rewards. XPX also functions as the required payment method for platform-specific services, including Sirius Storage, Sirius Stream, and decentralized database management.
MetX and XAR are specialized assets that complement the XPX token. MetX serves as a secondary utility token specifically tailored for the MetaXar gaming marketplace. XAR is a legacy stablecoin within the ecosystem that is often compared to the newer stablecoin minting protocols. These assets illustrate the platform's multi-token architecture, where different tokens are used for specific niche functions like gaming, governance, and value stability.
XPX operates on its own native mainnet but is also available as a bridged version on the BNB Smart Chain. For secure trading and management, users can access XPX through exchanges like LBank, which support the asset. For those using Web3 wallets like MetaMask, the bridged version can be added using the specific contract address, while native tokens are typically managed through official Sirius Chain wallet applications.
Mosaics and Namespaces are unique features inherited from the project’s technological heritage. Mosaics are custom, programmable assets or tokens created on the Sirius Chain, allowing developers to represent various types of value. Namespaces act as a decentralized naming system, providing human-readable aliases for accounts or assets, similar to a domain name. Together, they make the blockchain more accessible by replacing complex addresses with simple, recognizable labels.
