xx network Dedicated Nodes & RPC Infrastructure | OnFinality

Use OnFinality for xx network node access, API infrastructure, and dedicated node services. OnFinality supports teams that need reliable infrastructure for xx network applications, validators, and backend workflows.

What is xx network?

xx network is a fast, low-fee quantum-ready layer 1 blockchain built in tandem with the most private communications network in the world (cMix). Founded by the godfather of digital currency and privacy technology David Chaum, the xx network mainnet launched in November 2021. Nominated Proof-of-Stake (NPoS) incentivizes coin holders to run and elect nodes as well as to participate in the governance of the platform via on-chain DAO. The total supply of coins will grow to about 1 billion xx coins over the next five years and will be offset by a number of deflationary mechanisms.

By leveraging the xxDK, any application or blockchain can route their traffic through the xx network's communications layer in order to provide metadata privacy and quantum-secure encryption for all types of data communications. xx messenger, the first ever decentralized, quantum-secure, and E2E encrypted messaging app, is the first of many real-world applications built on this technology. Available on all major app stores, xx messenger's performance and unprecedented privacy has already attracted daily users in more than 65 countries.

Why use dedicated xx network nodes?

Dedicated nodes provide exclusive access to the xx network without sharing resources. This is critical for production dApps, validators, and services that require consistent performance, low latency, and full control over node configuration. OnFinality offers one-click deployment of full, archive, and validator nodes on globally distributed, multi-cloud infrastructure.

What developers use xx network RPC for?

Developers use xx network RPC endpoints to query blockchain data, submit transactions, and integrate with wallets, explorers, DeFi products, analytics tools, and backend services. Reliable RPC access is essential for building and maintaining applications on the xx network.
