확인해보니 A안이 gas수수료 한도 증가 + roll 사이즈 8000tz로 감소, B안이 gas 수수료 한도 증가 only이군요.
Getting the source code of both proposals
We just published the source code of both proposals for Athens: A, the one that includes the change in roll size from 10,000 to 8,000 tez and B the one without the roll size change. This code is exactly what we documented in our previous blog post. B simply does not include the change to roll size.
