Description

BEP-524: Short Block Interval Phase Two: 0.75 seconds

Rationale

tell us why we need these changes...

Example

add an example CLI or API response...

Changes

1. reduce block interval to 0.75s from 1.5s
2. Increase the epoch length from 500 to 1000. The transition occurs at the first block where Number % 1000 == 0 after the Maxwell hard fork.
3. clear minerHistory based on latest finalized blocks
4. Double Blob MinBlocksForBlobRequests and introduce MinTimeDurationForBlobRequests to determine whether blob data is needed.

Pull Request Overview

This PR implements the BEP-524 changes for Short Block Interval Phase Two by reducing the block interval to 0.75 seconds, increasing the epoch length, and updating blob request configurations.

• Block interval changes across the consensus and miner modules
• Epoch length update and improved blob configuration with clearing of miner history
• Adjustments to ancillary utilities and configuration values to support the new timing parameters
