Nothing Up My Sleeve Number
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
When designing algorithms, to prove that parameters (such as constants) were not chosen specifically to leave a backdoor, designers use mathematically recognized 'innocent' numbers (e.g., digits of π, the golden ratio).
SCAFFOLDING EFFECT
Reduce cognitive load
Self-certifying transparency. When building credibility, don't just say 'trust me', but use public, random, non-manipulable external standards (e.g., blockchain hash values, public lottery results) as decision bases to eliminate others' conspiracy suspicions.
Anchor fast decisions
'Nothing-up-my-sleeve number' refers to choosing seemingly harmless, explainable sources (e.g., digits of π) when constructing cryptographic constants, to prove no hidden backdoor.
