Goals

The purpose of this meeting is to discuss Dave's findings of RHOC held in contracts and consider next steps to help assure people are successful with the swap. David's findings are at https://gist.github.com/desaperados/98e4cf3d8c2fcefd4b6d7a5a3cb856a6

Review of findings
How the software works
  • https://github.com/makerdao/vulcan0x
  • Its a generic ERC20 cache
  • Schema
    • Collection of transaction data
    • Collection of account state
  • It's a docker stack that is easy to stand up and operate
  • It is a full Ethereum node
Discusion about selecting the block height for swap (timestamp project)
  • We need a way to estimate the block height leading up to the freeze before the swap
    • This needs to be communicated to exchanges to encourage them to freeze trading
  • Needs to be somewhat ambiguous to protect from phishing scams
  • Metaphor - like a count down clock
  • Concern - long strings of zeros may cause confusion
    • We need to leave enough room so that if things roll over, we're not committing to a bit that could roll over
    • We want to avoid deploying software as a service to mitigate liability risks
  • We need a script that given a date, picks a block height that we can publish bit by bit
  • The cache solution has a few layers between script and truth of the Ethereum blockchain
    • This may not support the solution to this need
  • Can we do a fuzzy countdown clock?
    • Count down each time an Ethereum block passes?
    • It should suffice to publish a range "after this block, and before that block"
    • A shrinking bullseye
Next steps
  • Idea to stand up the code on a machine owned by the Coop or share via API
  • Recommendation to provide the code for people to use if they want to explore the blockchain in a similar way.
    • We want to avoid standing up infrastructure that others might misconstrue
    • Reduces liability to the Coop
  • Idea - consider language for the RHOC/REV page to encourage exchanges to do right by their customers and tips for RHOC holders who use exchanges

Action items

  • Nash Foster by July 2 to review the software to better understand if and how it could be used
  • David to review the software to assure usability
