Initial support of the upcoming Napoli hard fork on Polygon – see [PIP-33](https://forum.polygon.technology/t/pip-33-napoli-upgrade). Per [PIP-31](https://github.com/maticnetwork/Polygon-Improvement-Proposals/blob/main/PIPs/PIP-31.md), it parallels the [Cancun](https://github.com/ethereum/execution-specs/blob/master/network-upgrades/mainnet-upgrades/cancun.md) upgrade of Ethereum, but does not include [EIP-4788](https://eips.ethereum.org/EIPS/eip-4788), [EIP-4844](https://eips.ethereum.org/EIPS/eip-4844), [EIP-7516](https://eips.ethereum.org/EIPS/eip-7516). In other words, Napoli includes [EIP-1153](https://eips.ethereum.org/EIPS/eip-1153), [EIP-5656](https://eips.ethereum.org/EIPS/eip-5656), [EIP-6780](https://eips.ethereum.org/EIPS/eip-6780) from Cancun. This PR implements [PIP-31](https://github.com/maticnetwork/Polygon-Improvement-Proposals/blob/main/PIPs/PIP-31.md), [PIP-16: Transaction Dependency Data](https://github.com/maticnetwork/Polygon-Improvement-Proposals/blob/main/PIPs/PIP-16.md) (by merging `ParallelUniverseBlock` into `NapoliBlock`; the bulk of PIP-16 was implemented in PR #8037), and [PIP-27: Precompiled for secp256r1 Curve Support](https://github.com/maticnetwork/Polygon-Improvement-Proposals/blob/main/PIPs/PIP-27.md) ([EIP-7212](https://eips.ethereum.org/EIPS/eip-7212); see also https://github.com/maticnetwork/bor/pull/1069 & https://github.com/ethereum/go-ethereum/pull/27540). --------- Co-authored-by: Anshal Shukla <shukla.anshal85@gmail.com> |
