2018-06-26 Meeting note: RHOC/REV - contract findings

Resources

• David's findings are at https://gist.github.com/desaperados/98e4cf3d8c2fcefd4b6d7a5a3cb856a6

Review of findings

• Amounts are incorrect in the gist in the balances. This is less important than having the number of contracts holding RHOC.

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
