How to sync blocks from genesis(block #0)

• (0) You should know Debug: panicked at 'Storage root must match that calculated ' #609
  if you use ChainX v4.x.x directly sync blocks will be stuck at #881910 or other block.
• (1) Compile ChainX v3.0.0 by nightly-2020-09-30 or Download chainx-v3.0.0-ubuntu20.04-x86_64-unknown-linux-gnu-1
  the ChainX v3.0.0 seed nodes are bad, so you should use new mainnet bootnodes with --bootnodes

"/ip4/120.26.57.227/tcp/36789/ws/p2p/12D3KooWEAX2BcQCZP79MuxQpqLQUop7P3tZY97eNxxUgc4ZTu3k"

• (2) Until #3038400, please use ChainX v3.0.0 to synchronize with NativeElseWasm (default mode)
• (3) For blocks after #3038400, complete (2) first, and then replace ChainX v3.0.0 with ChainX v4.x.x to complete the db migration (note that the migration process is irreversible, it is recommended to back up the data first)
• (4) ChainX v4.x.x continues to synchronize blocks
