For the published 15-element Poseidon1/KoalaBear input instance H(0xc09de4,·), find two distinct inputs whose first q output elements collide, for any still-open milestone q=4,5,6,7.
For the published 15-element Poseidon1/KoalaBear input instance H(0xc09de4,·), find two distinct inputs whose first q output elements collide, for any still-open milestone q=4,5,6,7.
Find a Poseidon1/KoalaBear partial collision matching the first 4 output elements for the published instance. The first qualifying submission wins; a report is due within one month and code/report must become public under the posted timetable.
Nested milestones: a stronger collision also meets weaker thresholds, and the rules do not clearly guarantee stacked payouts.
Find a Poseidon1/KoalaBear partial collision matching the first 5 output elements for the published instance. The first qualifying submission wins; a report is due within one month and code/report must become public under the posted timetable.
Nested milestones: a stronger collision also meets weaker thresholds, and the rules do not clearly guarantee stacked payouts.
Find a Poseidon1/KoalaBear partial collision matching the first 6 output elements for the published instance. The first qualifying submission wins; a report is due within one month and code/report must become public under the posted timetable.
Nested milestones: a stronger collision also meets weaker thresholds, and the rules do not clearly guarantee stacked payouts.
Find a Poseidon1/KoalaBear partial collision matching the first 7 output elements for the published instance. The first qualifying submission wins; a report is due within one month and code/report must become public under the posted timetable.
