What is Hackathon?
A hackathon is a time-boxed build competition, often with prize pools and sponsor tracks. In Web3 it is a primary hiring and grant funnel, not only a weekend contest.
In practice
Sponsors watch hackathons to find engineers who ship under constraints, and many grants and jobs start as a submission. The output is durable proof: a public repository, a demo, and a placement, all attributable to you and all verifiable by someone else later.
