I have a question about how to local a transaction in which shard
User A has two account which one in shard A and the other in shard B. User B has an account in shard C.
User A want to transfer all the money to User B account.
Shard node how to know the money in which shard? User need to provide the transactionID in which shard to the node?
Or in other words, If one network node want to find No.002 transaction. but this node doesn’t know this transaction in which shard. What does this node will do to find the transaction?
