Polygon Bids Adieu to Mumbai Testnet, Welcomes new UX with Napoli upgrade

• Polygon PoS is seeing an upgrade in tandem to Ethereum’s Dencun upgrade
• The Napoli upgrade is an upgrade of Ethereum’s Cancun upgrade, bringing multiple benefits to nodes and improving the overall health of the network.

Polygon (formerly known as Matic Network) is continuing to make strides in improving the user experience and network efficiency with their brand new upgrade that has just dropped. The Napoli upgrade aims to enhance the overall functionality of the Polygon platform and provide users with a better experience. The Napoli update aims to improve the user experience and the Polygon platform’s overall functionality. Accompanying it would be the updated UX that was selected by the community through voting. The Napoli update went live on the mainnet to enable developers to expand the network and take advantage of the daily surge in on-chain activity.

What to expect from the Napoli Upgrade

The community has approved several PIPs that make up the Napoli upgrade, and they are now live. These changes include the adoption of a new precompile for better account abstraction, which activates Ethereum’s RIP-7212 for the Polygon PoS network. This will provide a gas-friendly verification of ECDSA signatures, making smart account management more efficient and flexible.

PIP-27 adds a new precompile for the secp256r1 elliptic curve. As a result, proving elliptic curve signatures on rollups and Layer 2s becomes less expensive. With this precompile, developers may incorporate the popular secp256r1 curve into smart accounts, freeing up design space for key management and device-initiated transactions. All developers will benefit from improved user experience and increased design freedom.

PIP-16 upgrades parallel execution, one of the first EVM chains. This allows the Polygon PoS network to identify and execute multiple transactions in parallel, as long as block producers and validators understand when dependencies exist in any given block. However, all nodes will still need to compute transaction dependencies, so PIP-16 sets the stage for even better parallelization.

New EVM opcodes are added in PIP-31 for Polygon PoS. These include transient storage through two new opcodes, TLOAD and TSTORE, as well as MLOAD and MSTORE instructions, and changes to how the SELFDESTRUCT opcode works.

To sum it up, the Napoli upgrade is an upgrade of Ethereum’s Cancun upgrade, bringing multiple benefits to nodes and improving the overall health of the network. The Napoli upgrade not only will improve network parallelization but will also make major improvements to storage management and opcode performance. As the Mumbai testnet and Ethereum Goerli Faucet are scheduled to go offline on April 13, users are encouraged to prepare for the upcoming changes to continue using the network efficiently.
