Congrats to @nullcount, who claimed bounty 0!
Bounty 1 will be both easier and harder. See the bounty page for details.
The oldest ordinal sent to the submission address by the end of the next difficulty adjustment period wins.
This means that right now, a submission containing any ordinals will take the lead, but further submissions will need to contain an ordinal lower than the current leader, making it get progressively harder as more ordinals are submitted.
