Notes on Open Source Governance Models

Node.js Foundation

  • Healthy Open Source
    • explicit goal to be a lightweight process
    • concrete ability to scale to hundreds of contributors
    • good fundamental goals
      • transparency
      • participation
      • efficacy
    • ecosystem projects encouraged but not required to adopt foundation governance templates
  • creation of projects under TSC explicity delegates authority from TSC to project TC

Requirements for a Tendermint client

Requirements for a Tendermint client

Broadcasting transactions

  1. An evil proposer can drop valid transactions (tendermint/tendermint#3322). To ensure tx A will be committed, the client needs to a) send it to multiple nodes b) subscribe for its result or query the result later using /tx API endpoint (requires the tx indexer enabled)

  2. Multiple nodes above requirement comes from a simple fact that an evil node can drop your tx.
