The take

What to know

Patrick O'Grady is the founder of Commonware, an open-source Rust library of modular blockchain primitives whose Simplex BFT consensus powers Tempo's sub-second finality. A former VP of Engineering at Ava Labs and earlier a Coinbase engineer (Rosetta), his link to Tempo is indirect — through Commonware — and Tempo led a ~$25M strategic investment into his company.

Best for

  • +Understanding who builds Tempo's consensus layer
  • +Tracing Tempo's BFT finality back to Commonware and Simplex BFT
  • +Connecting prior Ava Labs and Coinbase engineering experience to Tempo's stack

Watch out

  • He leads Commonware, a separate company — he is not a disclosed Tempo employee; conflating the two misstates the relationship.
  • Tempo has no native token and no airdrop; the ~$25M was a strategic investment, not a token sale.
