Ed’s post from Discord on Dec. 24

@odeac: and I had a good discussion just now. Looks like the mechanism for a wallet dApp to get the history of a user's Rev sends and receives might be best implemented with a new Account contract abstraction that stores its own history. The existing BasicWallet and Purse contracts and other block/DAG mechanisms obscure that type of audit trail (which could be considered a feature). However, for the adoption of RChain, a user must be able to see their conventionally transacted Rev Send and Receive history from a co-op provided dApp (e.g. a command-line wallet). WalletCheck will likely need some enhancements. I'm hoping that @odeac: or others will arrange a meeting for himself and some subset of @dckc: @kayvan: @kellyfoster: @Ned: @Kent: and me later this week to discuss how some of the requirements will be implemented.

Higher abstraction of a wallet

  • Don’t give purse and wallet to users,

    • Challenge is it is difficult for users and creates risks creating contracts that add complexity where it’s not needed

  •  

Rholang challenges

  • Contract for wallet is not so difficult

  • Ovidiu discussed with Kent

  • What is difficult is preparing the Rholang infrastructure and test and debug the contract

    • NEED ability to test and debug Rholang outside of the VM

  • IDEA a wallet could be encapsulated in a single contract

Naming conventions for wallets

  • Concern the RChain wallet is not aligned to the industry. It will confuse users

  • Recommendation for nomenclature

    • Change how we've used “wallet” to date

    • Definitions

      • wallet = Client app for interacting with funds

      • account = Contract storing REV, public interface for storage of funds

      • purse = implementation detail and not visible to users of an account. Risk of losing traceability of funds.

  • design an account and an account contract
