Delayed Balance Substraction on Cross-shard Transactions #919
Description
The Prometheus server was supposed to count the balance of each shard when the cross-shard transaction happens (#918), but the result sometimes gets wrong.
In this case, shard 0 transferred balances to each other shards(1 ~ 7), the curve of the total balance is supposed to be smooth but not.
Transactions happened at time 13:27:45, we can notice a total balance increase, which shouldn’t be there. When we dived deep into the change of each shard, we found that the balance of shard 1~7 increased as expected at time 13:27:45.
But the balance of shard 0 began to decrease till 13:31:45:
Normally, the counting script would observe the decrease of sender first and then the increase of receiver:
