Story

What the post asked, what the answer turned out to be, and what the chain says happened. The record below holds the data.

The road block

Multiple choice: Second or SECOND. The post says which one. The field is the problem.

It was the text of a tweet scheduled for the next day, The race starts now. Until then nobody could claim this block, or block 67 behind it. The idea: a full day to think, then a lottery. The author didn't like the result.
