## Definition
A **backer** is a participant who allocates capital or tokenized support behind another participant's future performance without performing or adjudicating the task directly. In [[wiki/Immunefi Hacker Pledging|Immunefi Hacker Pledging]], the role is distinct from sponsor, researcher, judge, protocol, and spectator.
## Significance
The role turns reputation into an object of selection and pricing. It creates a bridge among [[wiki/Fantasy Sports|fantasy management]], [[wiki/On-Chain Reputation|on-chain reputation]], and cyber talent discovery without establishing military tasking.
