Polygon crypto activated its Giugliano hardfork on mainnet at block 85,268,500 on April 8, aiming for a measurable reduction in transaction finality by allowing block producers to announce blocks earlier in the confirmation cycle.
The Polygon Foundation confirmed the upgrade in a post on X, citing a demonstrated 2-second reduction in finality time during testing on the Amoy testnet last month. For a network that spent much of the last year dealing with stability incidents rather than improving performance, Giugliano represents a deliberate return to throughput and developer experience as the primary narrative.
Giugliano upgrade
The Giugliano hardfork will be released on the Polygon mainnet at block number 85,268,500, around 2 p.m. UTC on April 8.
This upgrade: enables faster finality by allowing producers to announce blocks earlier, adds fee settings directly in block headers,…

We believe the timing of this upgrade is as strategic as its mechanics. Polygon has visibly rebuilt its credibility since a finality bug in September triggered a hardfork to resolve transaction delays, and a separate validator release in July caused an hour-long network outage — both of which drew increased scrutiny at a time when competing layer 2 networks were winning over developers.
Deploying Giugliano now, cleanly and on a announced schedule, sends a signal to institutional integrators and dApp developers that Polygon’s engineering pipeline is working – a signal the network needed to send before the competitive gap widens further.

Polygon Crypto Giugliano Hardfork Mechanics: What the Change in Purpose Really Does
Giugliano’s upgrade – officially documented as PIP-84 in the Polygon Improvement Proposals forum – introduces three discrete changes to the Polygon PoS chain. Block producers can now announce blocks earlier in the pipeline, reducing the window between block creation and confirmation; fee parameters are embedded directly in block headers rather than requiring a separate lookup; and new RPC endpoints more efficiently deliver fee data to wallets and applications querying the network.
The practical consequence of the first change is the 2 second finality reduction observed on Amoy, where the upgrade took place at block 35,573,500 on March 23 without reported incident.
Before Giugliano, the confirmation window included latency due to producer announcement delay; after that, the producers broadcast earlier and the channel reaches an agreement more quickly. For high-frequency DeFi protocols and payment applications – both use cases that Polygon has explicitly prioritized in its Gigagas roadmap – a reduction of 2 seconds is not cosmetic. It’s the difference between a rule layer that can compete with card rails and one that can’t.
Reminder: PIP-85 activates on Polygon PoS starting at block 85,245,000, while the Giugliano hardfork itself is scheduled later at block 85,268,500 (~2 p.m. UTC April 8).

Changing fee settings has a more discrete but structurally significant implication for developers: embedding fee data in block headers reduces the number of RPC calls a dApp must make to construct a transaction, reducing operational overhead and improving the responsiveness of wallets and trading interfaces.
Node operators must upgrade to Bor v2.7.0 or Erigon v3.5.0 before the activation block to stay in sync – the Foundation explicitly flagged this requirement and Amoy’s testnet cycle served as a final validation pass before mainnet deployment.
It’s also worth noting that Giugliano carries over changes from PIP-66, which were initially included in the previous Bhilai hardfork, but were later reverted after behavioral issues emerged post-deployment. The Polygon team reviewed and refined this implementation before reintroducing it here – meaning that Giugliano is not a first attempt at this mechanic but a patched second pass, which significantly changes how his Amoy success should be read.
