Helios Layer 1 Blockchain Launches Public Testnet with 400,000+ Users

June 26, 2025 – Helios, a new Layer 1 blockchain designed for cross-chain composability and AI-native infrastructure, has officially launched its public testnet. Since going live, the network has attracted over 400,000 users and processed more than 3.5 million transactions, signaling strong early momentum.

Key Innovations in Helios Testnet

• IPoSR Consensus: Validators earn participation not just through stake, but by building and maintaining a strong on-chain reputation.
• Bridge-Free Interoperability: Native support for secure cross-chain smart contract calls, eliminating reliance on traditional bridges.
• Chronos Tasks: A built-in scheduling system for automated smart contract execution, bots, and AI agents. A Helios onchain action can trigger actions on external blockchains as well.
• Hyperion Modules: Modular extensions that allow nodes to serve as decentralized oracles, cross-chain verifiers, and relayers.
• Developer Revenue Sharing: Developers receive a share of the gas fees generated by the smart contracts they deploy.

"Surpassing 400,000 users in the testnet phase shows that developers and communities are ready for a new type of blockchain, focused on enabling new use cases that work for them." — Christian Alexandrescu, CMO at Helios.

Next-Generation Blockchain Architecture

Unlike traditional Layer 1 chains, Helios is engineered from the ground up to support real-time external contract calls, developer revenue sharing, and modular execution layers. The network's unique architecture allows developers to interact with contracts across ecosystems without relying on bridges or wrapped assets, dramatically reducing security risks and unlocking powerful cross-chain use cases.

Ecosystem Growth and Future Plans

Early testers have participated in community quests and dApp deployments. A retroactive rewards program is in place for builders who contribute meaningfully to the ecosystem. Initial feedback highlights the ease of integration and the developer-first experience Helios offers.

In addition to what is already live, partners (ranging from DeFi applications to infrastructure and tooling providers) are preparing integrations.

Helios's validator program will begin onboarding node operators globally, with a focus on decentralization, efficiency, and community representation. Detailed guides will be provided for those interested in running validators, positioning the chain for a robust and secure mainnet launch later this year.
