State

The x/bank module keeps state of three primary objects:

1. Account balances
2. Denomination metadata
3. The total supply of all balances

In addition, the x/bank module keeps the following indexes to manage the aforementioned state:

• Supply Index: 0x0 | byte(denom) -> byte(amount)
• Denom Metadata Index: 0x1 | byte(denom) -> ProtocolBuffer(Metadata)
• Balances Index: 0x2 | byte(address length) | []byte(address) | []byte(balance.Denom) -> ProtocolBuffer(balance)
• Reverse Denomination to Address Index: 0x03 | byte(denom) | 0x00 | []byte(address) -> 0
