 The record can encode arbitrary application information. The "amount" key is the data payload that the record carries.
 An entry which has a `visibility` of `private` is encrypted and stored on the ledger.
 This enables users to securely and privately transfer record data and values between one another over the public network.
 Only the sender and receiver with their corresponding account view keys are able to decrypt the private entries.

 ### Account Model
 In the account model as used in Ethereum, the application state can be found by referencing to a particular address.
 
 As such, anyone would be able to view the activities of any account, simply with the knowledge of the address.

 ### Updating State
 In the record model, applications update their state by consuming records containing the old state, and producing new records that contain the updated state. Records that have been used will be marked as spent and cannot be used again.
