blockchainer/network: move StateSync interface to the user Only network package cares about it. 2022-01-12 21:20:03 +00:00			`package network`
core: implement statesync module And support GetMPTData and MPTData P2P commands. 2021-07-30 13:57:42 +00:00

network: decouple it from blockchainer.Blockchainer We don't need all of it. 2022-01-14 01:09:54 +00:00			`Blockqueuer`

network: request unknown MPT nodes In this commit: 1. Request unknown MPT nodes from peers. Note, that StateSync module itself shouldn't be responsible for nodes requests, that's a server duty. 2. Do not request the same node twice, check if it is in storage already. If so, then the only thing remaining is to update refcounter. 2021-08-13 09:46:23 +00:00			`GetUnknownMPTNodesBatch(limit int) []util.Uint256`
