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.
