Pi Network completes Protocol 21 upgrade, boosting mainnet readiness

Pi Network announced the completion of its Protocol 21 upgrade, a major technical milestone that strengthens the foundation for an open mainnet and supports Web3 dApp development [3]. The update coincides with broader wallet integration, node version 23 upgrades, AI‑assisted app tools, and a sizable token unlock schedule.

Key takeaways

• Protocol 21 improves transaction speed, data storage and validator efficiency, targeting sub‑5‑second finality and 1,000 TPS [2].
• Node operators have upgraded to version 23, enabling smart‑contract support and cross‑chain bridge plans [1].
• Pi now appears in trending public‑chain lists of major Web3 wallets, allowing one‑click connections and expanding user reach [1].
• The Pi App Studio tool lets creators build AI‑driven apps without deep coding, while over 200 million PI are set to unlock this month [1].
• Alignment with Stellar Core V21 standards reduces latency and eases migration for developers familiar with Stellar’s ecosystem [3].

Protocol 21 delivers speed, scalability and developer-friendly tools

The Protocol 21 upgrade replaces the older Stellar Consensus fork with enhancements drawn from Stellar Core V21, delivering faster block finality (under five seconds) and higher throughput (up to 1,000 transactions per second) [2]. By lightening data storage requirements and optimizing validator communication, the network can sustain larger transaction volumes without degrading performance, a crucial step for a mobile‑first blockchain that serves millions of daily users. The upgrade also introduces new SDKs, APIs and real‑time updates that streamline dApp creation, while smart‑contract templates simplify common functions such as payments and token swaps [2].

Expanded access and ecosystem growth initiatives

Alongside the protocol upgrade, Pi Network reported that its chain now ranks among trending public chains in several mainstream Web3 wallets, enabling users to connect with a single click and avoid manual RPC configuration [1]. The v23 node rollout, which includes smart‑contract capabilities and plans for a cross‑chain bridge, further prepares the network for broader ecosystem integration [1]. In parallel, Pi’s App Studio offers AI‑powered development tools, allowing creators to generate apps using OpenAI Codex, Claude Code or Replit without extensive coding expertise [1]. The project also disclosed that more than 200 million PI tokens will unlock this month, with an additional 1.65 billion slated for release over the next year [1].

Why it matters

The Protocol 21 upgrade marks Pi Network’s transition from a closed test environment to a production‑grade mainnet capable of supporting high‑throughput Web3 applications. By aligning with proven open‑source standards and enhancing node performance, Pi aims to attract developers who might otherwise favor faster, lower‑cost chains. Combined with easier wallet access and AI‑driven app tooling, the network is positioning itself for a larger ecosystem of dApps ahead of an open‑mainnet launch. Future milestones will likely focus on verifying more users through KYC processes, expanding the number of active applications, and potentially deploying the announced cross‑chain bridge, all of which will determine whether the technical upgrades translate into sustained user and developer adoption.
