Ghost spends (coin unexpectedly spent by a wallet with shared data) - * 2. Ghost withdrawals (reserve unexpectedly emptied by another wallet with shared data) - * 3. Track losses through re-denomination of payments/refreshes - * 4. (Feature:) Payments to own bank account and P2P-payments need to be backed up - * 5. Track last/next update time, so on restore we need to do less work - * 6. Currency render preferences? - * - * Questions: - * 1. What happens when two backups are merged that have - * the same coin in different refresh groups? - * => Both are added, one will eventually fail - * 2. Should we make more information forgettable? I.e. is - * the coin selection still relevant for a purchase after the coins - * are legally expired? - * => Yes, still needs to be implemented - * 3. What about re-denominations / re-selection of payment coins? - * Is it enough to store a clock value for the selection? - * => Coin derivation should also consider denom pub hash - * - * General considerations / decisions: - * 1. Information about previously occurring errors and - * retries is never backed up. - * 2. The ToS text of an exchange is never backed up. - * 3. Derived information is never backed up (hashed values, public keys - * when we know the private key). - * - * @author Florian Dold <dold@taler.net> - */ - -/** - * Imports. - */ -import { Duration, Timestamp } from "../util/time"; - -/** - * Type alias for strings that are to be treated like amounts. - */ -type BackupAmountString = string; - -/** - * A human-recognizable identifier here that is - * reasonable unique and assigned the first time the wallet is - * started/installed, such as: - * - * `${wallet-implementation} ${os} ${hostname} (${short-uid})` - * => e.g. "GNU Taler Android iceking ABC123" - */ -type DeviceIdString = string; - -/** - * Lamport clock timestamp. - */ -export interface ClockStamp { - deviceId: string; - value: number; -} - -/** - * Contract terms JSON. - */ -type RawContractTerms = any; - -/** - * Content of the backup. - * - * The contents of the wallet must be serialized in a deterministic - * way across implementations, so that the normalized backup content - * JSON is identical when the wallet's content is identical. - */ -export interface WalletBackupContentV1 { - /** - * Magic constant to identify that this is a backup content JSON. - */ - schema_id: "gnu-taler-wallet-backup-content"; - - /** - * Version of the schema. - */ - schema_version: 1; - - /** - * Root public key of the wallet.
