proof of work (obs.): an archaic technique for (usually blockchain-based) cryp mining which ties mining capability to computational power. In its original form, it required transaction blocks to be hashed, which demonstrated time and computational effort put forth, and which would generate a certain amount of virgin cryp until the configured money supply was reached.

While widely criticized for its lack of scalability as transaction volumes grew and the extreme wastefulness of resources (both material and energetic) required¹ to maintain equivalent mining capacity in the face of the ongoing general expansion of computational capability, it nevertheless became a relatively commonly utilized technique in early cryp architectures.

A substantial blow was struck² to proof of work by the algorithmic crisis associated with the Isif Theorem and the Great Slump of 2840. Nevertheless, the concept staggered on for some considerable time afterwards, although the need for increasingly sophisticated cryptographic algorithms and specialized processors rapidly took mining of proof-of-work-based cryp outside the realm of individuals and small organizations. This left only large consortia of various types (and, of course, Powers³) capable of mustering the computational power necessary to participate.

The final death of proof of work did not come until 5193, when the Market Liberty Oversight Directorate – with the assistance of the Fiscal Mind and a specialized acausal logic processor – demonstrated the ability to mine out the entire volume of three newly launched cryps, using dust transactions to rapidly fill new mineable blocks, within seconds of each one’s launch.

  1. For this reason, proof of work was never a popular basis for Empire-based cryps. It is hard, after all, to imagine a domicile less friendly to the notion of deliberately overworking.
  2. Although a prolonged one, as much of the actual striking occurred after the advent of interstellar travel as word of the Theorem spread throughout what would become the Worlds at the speed of communications.
  3. A group whose existence enhanced the flight from proof of work, since those who were already concerned with confidentiality were, by and large, not enthusiastic about currencies seemingly doomed to fall under the control of alien space-gods.
