What should I know about the xx network?

What is the xx network?

The xx network is a quantum-resistant layer 1 blockchain designed to provide secure, private communications and transactions. It integrates a decentralized mixnet called cMix, which shreds metadata to protect user privacy. The network was founded by David Chaum, a pioneer in digital currency and cryptography, and launched its mainnet in November 2021.

xx network uses Nominated Proof-of-Stake (NPoS) consensus, where coin holders nominate validators to secure the network. The native token XX is used for transaction fees, staking, and on-chain governance. The total supply is capped at approximately 1 billion coins, with deflationary mechanisms in place.

• Quantum-resistant encryption and metadata protection via cMix mixnet.
• NPoS consensus with low fees and fast finality.
• xxDK allows any application to route traffic through the privacy layer.
• xx messenger is the first decentralized, quantum-secure messaging app.

RPC infrastructure decision checklist

Use this checklist to turn the RPC infrastructure question into a practical infrastructure decision instead of a generic provider comparison.

Start with the workflow you need to support, then verify the endpoint, method coverage, test environment, and next step before relying on it in production.

• List the exact RPC methods, chains, and environments your app will call.
• Test with the same request pattern your frontend, backend, bot, dashboard, or indexer will use.
• Check whether archive, trace, WebSocket, testnet, analytics, or dedicated-node access is actually required.
• Review pricing, usage visibility, and upgrade paths before moving sustained traffic.

Why Developers Need xx Network RPC Endpoints

To build on the xx network, developers need to interact with the blockchain via RPC (Remote Procedure Call) endpoints. These endpoints allow dApps to query account balances, submit transactions, read smart contract state, and listen for events. Without reliable RPC infrastructure, applications may suffer from downtime, slow responses, or inaccurate data.

Public RPC endpoints are often rate-limited or unreliable for production use. For production-sensitive applications, using a professional RPC provider ensures consistent performance and scalability. OnFinality offers dedicated xx network nodes and RPC API services designed for high availability.

• JSON-RPC and WebSocket endpoints for real-time data.
• Full, archive, and validator node types available.
• Global infrastructure reduces latency for users worldwide.
• Production-grade SLAs and 24/7 monitoring.

How to Choose an xx Network RPC Provider

When selecting an RPC provider for the xx network, consider factors such as availability, latency, rate limits, and pricing. A provider with a distributed node infrastructure can offer better geographic coverage and redundancy. Additionally, support for WebSocket connections is important for real-time dApps.

OnFinality provides a transparent pricing model and allows you to deploy dedicated nodes with customizable configurations. You can also use the shared RPC API for development and testing before scaling to dedicated infrastructure.

Setting Up an xx Network Node with OnFinality

OnFinality simplifies node deployment for the xx network. You can choose from full, archive, or validator node types and deploy them across multiple cloud providers. The platform handles updates, backups, and monitoring automatically.

To get started, navigate to the xx network page on OnFinality, select your node type, and configure the desired region and resources. Once deployed, you will receive dedicated RPC endpoints and credentials. This is ideal for validators, dApp backends, and analytics pipelines.

• One-click deployment with no manual setup.
• Multi-cloud and multi-region support.
• Automatic backups and failover.
• Real-time metrics and alerts.

xx Network Use Cases and Ecosystem

The xx network's privacy features make it suitable for applications requiring metadata protection, such as secure messaging, decentralized identity, and confidential transactions. The xx messenger app demonstrates the network's capabilities, offering quantum-secure end-to-end encryption.

The xxDK enables other blockchains and dApps to integrate the privacy layer, expanding the ecosystem. Developers can build on xx network using familiar tools like Ethereum-compatible smart contracts (via the xx network's EVM compatibility) or custom Substrate-based pallets.

• Private messaging and communication dApps.
• Decentralized identity and credential management.
• Confidential DeFi and token transfers.
• Cross-chain privacy routing via xxDK.

Best Practices for xx Network dApp Development

When developing on the xx network, start by testing on a testnet (if available) or using a development node. Use WebSocket connections for real-time updates and implement proper error handling for RPC failures. Monitor gas fees and adjust transaction parameters accordingly.

For production, always use a dedicated RPC provider to avoid rate limits and ensure reliability. Consider deploying multiple nodes across different regions for redundancy. OnFinality's dedicated nodes come with built-in monitoring and alerting to help you maintain availability.

• Use WebSocket for event-driven updates.
• Implement retry logic for transient RPC errors.
• Monitor node health with external tools.
• Leverage archive nodes for historical data queries.
