Four questions. Every answer is somewhere real: a settlement receipt, a block explorer, a contract, and one that wants a GPU you can rent for pennies. Nobody judges your entry and nobody can pay late. The money sits in a contract that pays the first three solvers itself.

The four

01

Read a receipt

Every settled lease on Prism publishes a receipt. Find the one for transaction 0x06f378be25ee204c18ea9fa2bdf054f75a956f04b626f11d6050e8f92ab75c23. Which GPU served it?

02

Open the settlement

That same transaction settled in which block?

03

Ask the escrow

A settled lease can be disputed for a while before it finalises. Ask the escrow contract how many seconds that window is.

04

Rent a GPU

The last one is work rather than a lookup. Find the smallest whole number that refracts to zero, seeded with 0x5052. A laptop takes minutes; a rented GPU takes seconds.
