Sui Mainnet Upgraded to v1.63.3 with Protocol Enhancements

According to Foresight News, the Sui mainnet has been successfully upgraded to version 1.63.3, alongside a protocol upgrade to version 107. This update focuses on improving network stability, transaction finality, and security.

Key Highlights of the Update

🔹 Faster and More Reliable Transaction Finality

The upgrade improves the transaction and state processing pathways, allowing transactions to reach final confirmation more directly and consistently.

🔹 Consensus Stability Improvements

Previously, rejected transactions could cause inconsistencies among validator nodes. This issue has now been resolved, significantly reducing the risk of consensus divergence across the network.

🔹 Enhanced Network Security

As part of the protocol upgrade:

Validator nodes are now prohibited from signing user transactions

Submission of aggregated validator-signed transactions via RPC interfaces is no longer allowed

These changes strengthen decentralization and reduce potential abuse or centralization risks.

Overall Impact

✅ Improved network reliability

✅ Stronger security model

✅ Better user and developer experience

✅ Positive long-term fundamentals for the Sui ecosystem

Market Perspective

While this upgrade may not trigger an immediate price surge, it reinforces Sui’s long-term growth potential by laying a stronger technical foundation for scalable dApps, DeFi, and institutional adoption.
