2019-01-03 Meeting notes: wallet dApp

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.

Related Jira issues

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

Open questions

• How important is it to leverage ETH style for signing transactions (Dan)

  • Idea for an approach - Could we fork My Ether Wallet or Metamask to support this?

• How to address mulitsig?

  • Is it in the same account contract or is it something else (ex Locker)

    • What is a Locker? (Dan)

• How from a client perspective do we predict the unforgeable name?

  • https://rchain.atlassian.net/browse/RCHAIN-654

  • IDEA conversation: Dan, Ed, Ovidiu, Kayvan, Kent, Joshy (optional)

• What platform does the coop-provided wallet app run on?

  • Suggestion make it similar to RNode operation
