I broke the chain at the execution-spec-tests Devcon SEA workshop!

I attended the Ethereum Execution Spec Tests Workshop at Devcon SEA and broke the chain with Mario, Dimitry, Spencer. Danceratopz, Peter and Guru! I developed an execution layer consensus spec test in Python for EIP-5920: PAY Opcode and executed them against a live devnet! The test I wrote triggered an intentional bug hidden in an execution client running on a live devnet, breaking the chain!
