Polygon PoS Sidechain Implements Napoli Hard Fork, Adding Support for Upgrades Included in Dencun

cryptonews.com:

The  Polygon Proof-of-Stake (PoS) sidechain has successfully executed the Napoli hard fork, adding support for Dencun features and making it the first network to support RIP-7212. 

The  Napoli hard fork  introduces three significant upgrades from Ethereum’s  recent Dencun hard fork , namely EIP-1153: Transient Storage, EIP-6780: SELFDESTRUCT, and EIP-5656: memory copying instruction.

EIP-1153 aims to enhance the efficiency of block space utilization, optimizing the overall performance of the network. 

On the other hand, EIP-6780 restricts the functionality of the selfdestruct opcode, ensuring more secure and controlled operations. 

Meanwhile, EIP-5656 reduces the technical overhead associated with memory copying, and streamlining processes within the network.

As part of today's Napoli Hard Fork, Polygon PoS became the first chain to activate a Rollup Improvement Proposal (RIP) with RIP-7212, bringing support for a new precompile for the secp256r1 curve!

Polygon has also announced plans to incorporate support for EIP-4844, a critical fee-reducing upgrade featured in Dencun. 

This integration is expected to be part of Polygon’s upcoming Feijoa upgrade, scheduled for release in May.

One of the key highlights of the Napoli hard fork is the inclusion of RIP-7212, an upgrade that opens doors for mainstream interoperability. 

This upgrade was developed by RollCall, a collective of Layer 2 teams. 

RIP-7212 introduces precompile support for the secp256r1 curve, a widely used elliptic curve for digital signatures across the internet. 

Its adoption enables greater interoperability with mainstream technologies and devices, with potential applications in storing keys within
