Mining improvement proposal

Simple Summary

It is cheap for GPU miner to switch the mining block, so we can dynamically adjust the mining block in a single mining round to make sure the mining block almost includes the transactions with highest fee price and includes as much valid uncle blocks as possible.

Motivation

• A transaction that the user pays for a very high fee price may need to wait for a round of mining time before it can be processed.
• The time window for a round of mining is too large, so that the miner’s fee-based transaction selection strategy is not always optimal.

Simple Checkpoint Syncing

The purpose of this version checkpoint syncing is only to replace the hard-coded checkpoint information in the code, making the checkpoint updating more flexible.

Note: The current version of checkpoint syncing is still centralized.

Pre-requisites

• Deploy a checkpoint registrar contract on the mainnet.
