Pi Network Protocol 28 Mainnet upgrade

Pi Network activates Protocol 28 on its Mainnet on October 16, 2026. The upgrade concerns the network's native coin, PI, and changes how the blockchain handles transaction data and smart contract maintenance.

What is happening

The Pi Core Team confirmed on September 25 that Protocol 28 had reached Testnet, following the successful deployment of Protocol 27 on Mainnet. The upgrade is now scheduled for Mainnet activation on October 16, 2026, and the changes are being tested before they reach the network that handles users' actual balances.

Protocol 28 changes how the blockchain processes delays in transaction data. Developers gain the ability to upgrade groups of smart contracts together and to modify stored application information more safely. According to the team, the improvements are meant to support applications as their software and data requirements change. The release builds on Protocol 27, which introduced more flexible smart contract authentication.

Mainnet node operators are required to install version 28.0 by October 13, three days before activation, according to the official Pi Network node instructions. The upgrade does not include a confirmed launch date for OUSD or any new stablecoin integration feature. Pi Network treats its stablecoin work with Open Standard and the protocol upgrade as separate areas of development.

Why it matters

For the project, Protocol 28 continues the step-by-step expansion of Pi's smart contract capabilities. Easier grouped upgrades and safer handling of stored application data lower the maintenance burden for developers building on the network, which may make it simpler for applications to evolve over time.

For holders and traders, this is a technical milestone rather than a change to the token itself. It comes while PI trades under pressure, near $0.08 after a decline of roughly 10% over the previous week, according to CoinGecko data cited in the source article. The upgrade does not add stablecoin functionality or reward programs, so it should not be confused with the separate Open Standard partnership, for which no Mainnet date has been announced. Those following the event may want to watch whether node operators complete the version 28.0 update on time and whether activation proceeds on the scheduled date.
