  • launch new testnet every 2 or 3 years, pre-announce and "end-of-life date" (5 years lifetime? tbd)
  • goerli end of life: 2024?
  • sepolia end of life: 2026?
  • sepolia would be the right place to migrate/test applications
  • sepolia is permissionless, has better stability guarantees, and better total supply
