Notes

  1. Add game based definitions to the whitepaper.
  2. Scenario: Using blockchain as an immutable record keeper
    1. Security: Protection at the access level.
    2. Read access: Query from all the nodes and get the majority result.
    3. Game: Adversary modifying the state, can blockchain recover in a given timeframe.
  3. Projects to put security guarantees.
    1. Misunderstanding could lead to data loss.
  4. Confidentiality & Privacy:
    1. Pseudonymity: Otherwise one can know what transactions are sent by which parties. Anonymity will make it hard, i.e. somebody can still search through network traffic.
    2. Ask projects to define privacy and confidentiality.
    3. Define the terms (ex: zcash defines privacy clearly).
  5. Form a working group for security.
  6. Task force can focus on vulnerability disclosure process.
  7. Games around: consensus, networking, block data, state data.
