BIP85 deterministic entropy

A standard for deriving isolated child entropy such as new wallet seeds from one protected master seed.

A standard for deriving isolated child entropy such as new wallet seeds from one protected master seed.

BIP85 deterministic entropy is best understood as part of a system rather than as an isolated definition. Its related coordinates show the mechanisms, incentives and historical records that give the term practical meaning.

BIP85 deterministic entropy should be evaluated against a concrete threat model: what is protected, from whom, for how long and at what operational cost. A design may remove one dependency while introducing another, so custody, privacy and verification must be judged as a complete system.

Understanding BIP85 deterministic entropy helps distinguish a verifiable Bitcoin mechanism or historical record from slogans, products and market narratives.
