Bulletproof
A compact zero-knowledge proof construction often used to prove that hidden transaction amounts lie within valid ranges.
PLAIN-ENGLISH DEFINITION
In more detail
It supports those range checks without a trusted setup for the proof system. A valid range proof establishes the specific mathematical condition, rather than automatically proving every claim about a transaction or application.
IN THE WILD
How you might use it
A confidential transaction proves its hidden output amount is in range without publishing that amount.
