XPR Network (XPR)
XPR Network (formerly Proton Network) is a public, layer-one blockchain designed for both consumer and enterprise use cases[1]. Built on the Antelope protocol and leveraging a Delegated Proof-of-Stake (DPoS) consensus model, it aims to deliver high throughput, minimal latency, and zero-cost transactions for end users. With a focus on real-world use cases and developer accessibility, the platform positions itself as a strong foundation for decentralized finance, digital identity, supply chain transparency, and tokenized assets.
Token
The XPR token is designed with a controlled supply and moderate annual inflation, serving as a short-term store of value for decentralized applications (dApps) while enabling blockchain governance. At launch, 200 million XPR tokens will be in circulation, with an annual inflation rate of 5%. This inflation is allocated as follows: 2.5% to block producers, 1.5% to token stakers, and 1% to the Proton Steering Committee.
Block producers are responsible for validating nodes through the open-source Proton protocol. Transactions require a two-out-of-three consensus among producers and achieve finality within three minutes.

The Proton Steering Foundation receives 1% of the annual inflation and operates under a delegated proof-of-stake (dPos) model, with votes held every three months. Its role includes rewarding development teams from Metal and Lynx for contributions to Proton’s wallets, applications, and marketing. It also supports independent groups like CryptoLions for core blockchain work and fosters inter-blockchain communication (IBC) through Proton’s Secure Identity and multi-ecosystem standards.
Token stakers participate in governance by voting for block producers on a one-token, one-vote basis. To vote, they must bond their tokens, accepting the risk of economic penalties if their chosen producers underperform.
Core infrastructure and consensus
At its core, XPR Network utilizes the DPoS consensus mechanism, which relies on a group of elected block producers and token stakers to maintain chain integrity. Unlike Proof-of-Work systems, which require significant computational resources, DPoS is much more energy-efficient and scalable. This architecture allows the network to process up to 4,000 transactions per second (TPS) with near-instant finality.
The platform emphasizes decentralization, citing a high Nakamoto coefficient, which is a metric that reflects the number of nodes required to compromise the network, as evidence of its resilience against common blockchain threats such as double spending and 51% attacks. According to its developers, the network has experienced no downtime since the genesis block.
Zero gas fees and the resource model
A key differentiator of XPR Network is its gas-free model for end users. Unlike Ethereum and other major blockchains that require users to pay transaction fees, which often fluctuate based on network congestion, XPR Network provides users with free accounts and resources for transactions. Instead, developers and applications are responsible for acquiring computational resources via a monthly subscription model.
This architecture removes cost barriers for users while offering predictability for developers, which is particularly useful for applications in micropayments, gaming, and social media, where high-frequency interactions are common.
Applications across industries
XPR Network is marketed as a versatile platform capable of supporting a wide range of blockchain use cases:
Payments: With its high throughput and instant settlement, the network serves as an alternative to traditional systems like ACH, SWIFT, Visa, and Mastercard for both domestic and international transactions.
Supply chain transparency: Blockchain-based tracking of goods on XPR helps verify product origins and authenticity, which reduces fraud and enhances traceability.
Tokenized assets: The network supports the tokenization of physical assets such as real estate and art, allowing for fractional ownership and increased liquidity in traditionally illiquid markets.
DeFi ecosystem: XPR Network provides the infrastructure needed for lending, borrowing, and liquidity provisioning. It supports smart contracts and decentralized applications, making it well suited for various financial protocols.
Digital identity: It offers support for secure, verifiable identities to help minimize fraud within authentication and access control systems.
Developer experience
The XPR Network ecosystem is designed for accessibility, particularly for web developers. The primary language for smart contract development is TypeScript, utilized through a custom SDK[2]. The project prioritizes type safety and code consistency, especially when interacting with low-level blockchain functions.
The official GitHub repository offers examples and starter templates to help ease the learning curve. Developers are encouraged to use the testnet environment for experimentation prior to deploying on the mainnet. A typical developer stack consists of Node.js 20+, Git, and basic command-line proficiency[2].
Storage on XPR is intentionally limited, meaning developers should minimize on-chain data and offload heavy computations to external servers. This principle reflects a broader trend in blockchain design, where on-chain activity is reserved for validation and finality rather than compute-intensive tasks.
Ecosystem tools and account management
On the XPR Network, every account is a blockchain-registered identity capable of interacting with contracts and executing transactions. Accounts can be assigned various permissions via key-based or account-based authorities, enabling fine-grained control over actions and delegated access.
Developers and users can switch between testnet and mainnet by changing chain IDs or nodes. SDKs like @proton/web-sdk and @proton/react-native-sdk offer abstraction layers to simplify integration with front-end applications.
