Transaction and receipt storage was completely reworked, cutting the data storage requirements of a fast synced node in half, from 26.3GB to 14.9GB at the time of the implementation (#14801).

Transction 和 receipt 存儲被完全啟用，在實現(xiàn)時削去fast synced節(jié)點的一半的存儲需求

EVM log storage and indexing was completely reworked, cutting the filtering time of the entire chain for contract events by 2-3 orders of magnitude, from minutes to under a second (#14522,#14631).

Some work-in-progress updates that will land in the next releases are:

正在做的一些工作準(zhǔn)備在下個版本更新：

Upgrading the base peer-to-peer protocol used by all Ethereum sub-protocols, cutting the bandwidth needed for a fast sync from 33.6GB to 13.5GB (#15106). This upgrade will improve the general bandwidth requirement of the network as well as light clients too.

升級所有被以太坊子協(xié)議作為基礎(chǔ)的p2p協(xié)議，將fast sync的帶寬需求從33.6GB到13.5GB。

Introducing a more sophisticated memory caching for state tries, reducing disk IO by a couple orders of magnitude. Exact number are pending a final implementation (#14952).
