Resync from genesis. sync speed=22block/s, the average txn process time is 0.2ms. (6core12threads, 32G)

NOTE: javatron's average txn process time is 5+ms for a typical cloud server.

A Smart Contract call.

TVM exit reason mismatch. required=Unknown, opentron=Revert.

The energy calculation is OK before this.

A call to address(0x0) with value and data. All checks passed. Haven't figured out why.

Also to mention that, the account 0x0000000000000000000000000000000000000000, i.e. T9yD14Nj9j7xAB4dbGeiX9h8unkKHxuWwb is created at 5c7d1fd483b4facdcbcc8d6a7d833db59851b41b4274164d43b3112efb582ad9, block 3900143.

Update 2020/11/07

The contract is a revert-attack contract to a dice game. But the game contract is inited with address(0x0).

Update 2020/11/18

Resync and add massive debug code.

The problem is: Calling an empty contract with no value transfer bypasses validateForSmartContract.

Recorded as #45, Fixed.
