This update is a big step for the project. It sets the base for smart contracts, something the community has been waiting for. The Pi news today reports on the Pi Day updates. It shows the network is slowly moving toward real apps and real use cases.
Upgrade Brings Smart Contract Foundation
Protocol 20 brings the core support needed for smart contracts. Smart contracts are simple programs that run on the blockchain. They work automatically when certain rules are met. For example, they can handle payments, run subscriptions or manage digital items like NFTs.
With this upgrade, Pi network now has the tools needed to support these features. But the team made one thing clear. Smart contracts will not launch all at once. They will come step by step.
Focus on Real Use Cases First
The Pi team plans to focus on useful, real-world features first. They are not rushing into complex DeFi tools. Instead, they want things people can use in real life. For example, subscription-based contracts may come first.
These are used in many apps today, like monthly services. After that, features such as escrow contracts and NFT tools may follow. This shows Pi is trying to build a system based on real use, not just hype.
Careful Testing Before Launch
The rollout of smart contracts will follow a careful process. First, each contract will go through external audits. This helps make sure there are no bugs or security issues. Next, the contracts will be shared with the community for feedback.
Developers will then test them on the Testnet. They will move the updates to the Mainnet only when everything works properly. This step-by-step process may take time. However, it helps keep the network safe and stable.
Network and Tools Also Getting Upgraded
The upgrade is not just about smart contracts. Other tools like the Pi Wallet and Pi SDK will also get updates. These tools help users and developers interact with the network. The goal is to make everything smooth. Additionally, easy to use once smart contracts are live. This upgrade also builds on earlier updates like v19.6 and v19.9, which helped prepare the network.
A Big Step for the Pi Ecosystem
This upgrade is an important moment for Pi Network. For years, the project focused on growing its user base. Now, it is starting to build real features on top of that base. With smart contracts, developers can create apps and users can do more with their Pi.
The full rollout will take time. But this update shows the network is moving forward. Step by step, Pi Network is trying to turn its large community into a real world ecosystem.
