Details
- Polygon Chain mainnet activated the Giugliano hardfork at block 85,268,500 on April 8, 2026, delivering faster transaction finality, onchain fee transparency, and improved P2P throughput.
- Polygon Foundation leads the upgrade; involves 100 validators with 86 (90% staked weight) upgraded; requires Bor v2.7.0 or Erigon v3.5.0.
- Key features include ~2-second finality reduction via earlier block announcements (PIP-66), fee parameters in block headers with new RPC method (PIP-83), and 4x larger transaction queues for load resilience.
- Third upgrade in four months after Lisovo (March 4, dynamic gas) and gas limit expansion (March 23); builds on Bhilai (mid-2025, finality to 5s) toward Gigagas roadmap for payment-grade performance.
- Amoy testnet confirmed 2s finality drop; aligns with Polygon's scaling for payments/RWAs, outpacing prior instability; Solana hits higher TPS but Polygon emphasizes predictable fees for DeFi.
Impact
Giugliano advances Polygon's Gigagas roadmap, targeting 1,000 TPS and 5s finality by July 2026, enhancing competitiveness against Solana and Ethereum L2s for payments and RWAs. This compounds reliability for fintech adoption, potentially boosting developer activity amid POL price lag. Over 12-24 months, it could steer Web3 funding toward high-throughput PoS chains, accelerating enterprise onchain settlement.
