Cold storage

A custody setup that keeps signing secrets away from internet-connected systems.

A custody setup that keeps signing secrets away from internet-connected systems.

Cold storage 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.

Cold storage 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 Cold storage helps distinguish a verifiable Bitcoin mechanism or historical record from slogans, products and market narratives.
