Ustj V3n1

This issue of the Urbit Systems Technical Journal unveils technical descriptions of significant milestones in Urbit's ongoing development:

- The design and implementation of Urbit's named data networking scheme, Directed Messaging, a core component of the "Neo-Urbit" vision.

- "Subject knowledge analysis" for Hoon static analysis.

- Comet cryptography, a portion of the Groundwire proposal for a

revision of Urbit's peer-to-peer schema beyond Azimuth.

- The serialization mechanism for nouns.

- Obelisk, a return to E. F. Codd's relational algebra and SQL.

The Urbit Systems Technical Journal publishes articles on the ongoing

development of Urbit and on solid-state computing more. Like the

famous Bell System Technical Journal on which it is modeled, the

Urbit Systems Technical Journal aims to document the engineering work

necessary to realize the vision of computing as sovereign, deterministic,

and grounded on solid first principles. In so doing, we hope that these

technical problems come to interest and benefit the broader developer

community. Functional (as in programming) engineers are often on the

leading edge of software development, and the solutions they undertake

have required large-scale innovations in the field of computer science

generally. The volume of USTJ which you hold in your hand highlights

developments in the Nock computing system which underlies Urbit and

Nockchain. We welcome submissions from those engaged in making

computing more solid-state.
