dangerousfreedom - wallet work

What and Why ?

Make a basic but broad demonstrator of the seraphis_wallet by: opening a wallet, make mock transactions, make transaction proofs, show enotes and balance, close wallet. A lot of work has been done in this direction but they are not yet fully organized. So the goal is to have this basic but organized demonstrator capable of doing that.

I would work on the following tasks (but also on the many side tasks that need to be done to reach these goals):

• Create basic functions for wallet initialization, program flow and terminal handling.
• Create the basic components of a seraphis_wallet (basically the wallet needs to load/save the KeyContainer, EnoteStore and TransactionHistory components).
• Create basic function to fill EnoteStore.
• Use mock transactions like construct_tx_for_mock_ledger_v1 to create txs.
• Add entries to TransactionHistory when a transaction creation is attempted.
• Create terminal functions to show enotes and provide knowledge proofs.
• Close/save wallet and make sure it loads everything when reopened.

All the efforts will be documented and made public on the seraphis_wallet group. Unit_tests will be provided whenever possible.

Who?

• I did this, this and this previous works.

I propose to work for 40 USD per hour, 20h per week, for 12 weeks (or until I finish all the tasks), which makes 56 XMR considering 170 USD/XMR.

 ## What and Why ?
 
-The end goal of this proposal is to be able to make a basic but broad demonstrator of the seraphis_wallet by opening a wallet, use @jberman scanner to load legacy enotes, make transactions, make transaction proofs, show enotes and balance, close wallet. A lot of work has been done in this direction but they are not yet fully organized. So the goal is to have this basic but organized demonstrator capable of doing that.
+The end goal is twofold:
 
-In order to do so, I would work on the following tasks:
+1) Get started with a basic variant to handle transactions both in legacy and seraphis: since a blockchain is made of blocks and blocks are made of transactions, we probably need a class to handle node queries smoothly between the classes `transaction` and `SpTxSquashedV1`. Hopefully this will generate discussions and start paving the way for future works about reading/writing data from/in the blockchain (1/4 of total time).
+
+2) Make a basic but broad demonstrator of the seraphis_wallet by: opening a wallet, make mock transactions, make transaction proofs, show enotes and balance, close wallet. A lot of work has been done in this direction but they are not yet fully organized. So the goal is to have this basic but organized demonstrator capable of doing that (3/4 of total time).
+
+I would work on the following tasks:
+- Create the `TransactionVariant = tools::variant<transaction, SpTxSquashedV1>` to handle similar methods of these classes.
+- Create unit_tests with legacy and seraphis transactions to test these methods.
 - Create basic functions for wallet initialization, program flow and terminal handling.
 - Create the basic components of a seraphis_wallet (basically the wallet needs to load/save the `KeyContainer`, `EnoteStore` and `TransactionHistory` components). 
-- Create basic function to fill `EnoteStore` with jberman's scanner.
-- Create functions similar to `create_transaction_2`, `create_transactions_from` on wallet2 and `construct_tx_for_mock_ledger_v1` in seraphis_mock to send a tx.
+- Create basic function to fill `EnoteStore`.
+- Use mock transactions like `construct_tx_for_mock_ledger_v1` to create txs.
 - Add entries to `TransactionHistory` when a transaction creation is attempted.
 - Create terminal functions to show enotes and provide knowledge proofs.
-- Use/review/integrate @ghostway's work and @shalit's work on the key_container and on the EnoteStore serialization 
+- Close/save wallet and make sure it loads everything when reopened.
