Pi Network Completes Mainnet Upgrade to Protocol 21

Pi Network has completed another key step in its development. The team has successfully upgraded its Mainnet to Protocol 21. This update is part of Pi’s ongoing plan to improve its network step by step. 

The Pi Mainnet has successfully upgraded to Protocol 21.

Node operators, please ensure your systems are up to date and stay tuned for instructions regarding the upcoming v22 upgrade.

The update was announced by the Pi Core Team. They also asked node operators to make sure their systems are fully updated. While this upgrade sets the stage for the next update, Protocol 22, which is expected soon.

Upgrade Improves Network Performance

This upgrade mainly focuses on making the Pi network work better. It helps improve speed, stability and overall performance. In simple terms, the system should now run more smoothly, even as more users join. For node operators, this update is important. If they do not update their systems, they may lose connection to the network. So, the team has reminded everyone to stay updated and ready for the next steps.

Step-by-Step Roadmap Continues

Pi Network is following a step-by-step upgrade plan. Instead of making big changes all at once, the team is rolling out updates in stages. Each update builds on the last one. This helps avoid problems and keeps the network stable. Protocol 21 is one step in this journey. 

Next, the focus will shift to Protocol 22 and beyond. Developers expect these future updates to bring smart contracts and better tools. Consequently, creators can build more apps and features on Pi in the future.

Developer Tools Also Expanding

Pi Network is also working on helping developers. Recently, it introduced an RPC server on its Testnet. This tool helps developers connect to the blockchain and build apps more easily. Developers can test smart contracts and work with real-time data. Also, node operators can run their own RPC servers. This makes the network more open and less dependent on central systems. In simple words, Pi is trying to make building on its network easier.

Community Shows Mixed Reactions

The update has brought mixed reactions from the community. Many users are happy to see progress. They feel the project is moving forward step by step. But some users are still waiting for key updates. These include KYC approvals, migration progress and real world use cases. So, while there is excitement, there is also some frustration.

Focus Remains on Building the Network

For now, Pi Network is still growing. The Protocol 21 upgrade shows steady progress, but the journey is not complete yet. The team is focusing on building a strong system first. Then, it plans to expand features and use cases. In simple terms, Pi is still under development. But with each update, it is getting closer to becoming a fully working ecosystem.
