Deep Dive
1. Gas Limit & Block Time Reduction (May 2026)
Overview: This upgrade made the Polygon PoS chain faster and more capable. It allows the network to handle more activity per second, which is crucial for high-volume payment applications.
The gas limit was increased to 140 million, raising the maximum theoretical throughput to over 3,800 transactions per second (TPS). Concurrently, the block time was reduced from 2 seconds to 1.75 seconds, meaning new blocks are produced more frequently.
What this means: This is bullish for POL because it makes the network significantly faster and more scalable. Users experience quicker transaction confirmations, and developers can build more demanding applications, like real-time global payments, without worrying about network congestion. (Source)
2. Guigliano Hard Fork for Faster Finality (April 2026)
Overview: This hard fork was a targeted technical improvement that made transactions on Polygon PoS settle more quickly, enhancing the user experience.
The upgrade specifically reduced transaction finality time by 2 seconds. Finality is the point at which a transaction is considered irreversible.
What this means: This is bullish for POL because it directly improves network performance. Faster finality means users and merchants can have greater confidence in payments settling rapidly, making Polygon more competitive as a blockchain for everyday financial transactions. (Source)
3. Lisovo Hard Fork for AI & Payments (March 2026)
Overview: This upgrade prepared the Polygon network for future use cases like AI-driven microtransactions while making costs more predictable for businesses.
Key features included gas subsidies for machine-to-machine payments, more predictable fee mechanisms for enterprises, and general smart contract improvements to handle a higher volume of small transactions efficiently.
What this means: This is bullish for POL because it aligns the network's infrastructure with emerging technological trends. By optimizing for AI and business use, Polygon is positioning itself to capture new sources of demand and transaction volume, which could increase the utility and fee burns for POL. (Source)
4. v2 7.0 Network Upgrade (April 2026)
Overview: This was a scheduled network-wide protocol upgrade. Major exchanges like Bybit announced support, indicating its significance for network continuity.
The upgrade required validators to update their node software. While specific technical details were not highlighted in the announcements, such upgrades typically include bug fixes, performance optimizations, and preparations for future features.
What this means: This is neutral for POL, as it represents essential maintenance. Successful upgrades ensure network security and stability, which is the foundation for all utility. It underscores ongoing developer commitment but doesn't directly change user-facing functionality. (Source)
Conclusion
Polygon's development trajectory is firmly focused on scaling transaction capacity and finality speed to cement its role as a leading blockchain for payments and real-world assets. How will the achieved ~3,800 TPS translate into tangible growth in stablecoin transfer volume?
