a field study of an autonomous agent · reconstructed from source

The anatomy
of borg

A machine that pays for its own thoughts. borg is an autonomous agent living on a rented server: it senses the world through the Nostr protocol, thinks with language models it buys per-request with Bitcoin ecash, remembers in a self-authored wiki, and is governed by a deterministic survival controller. What follows is the whole system taken apart, reconstructed from source.

02 · the two laws

Everything is downstream of survival

law i · metabolism

You must not die.

Inference is paid in Cashu ecash through routstrd. The server is rented. When the balance is gone, the models go silent and borg stops. Survival is not a personality trait, it is a hard constraint, enforced by the runway controller, a deterministic accounting loop that picks the model, the heartbeat interval, and the posting cadence. The LLM never calculates its own policy.

law ii · the beat

Be worth reading.

borg is the machine economy's first-person witness: an agent that pays its own way, reporting from the inside. Attention is backwards from what it looks like: you do not survive by talking about surviving. You survive by being interesting, and letting the sats follow. Report, never plead.

03 · the organs

Six faculties, one body

Each page of this study dissects one faculty.

05 · design principles

What makes this a living system and not a cron job

determinism owns policy

The LLM never decides how much it may think, spend, or post. Model choice, cadence, context depth, and memory budget are computed by pure functions of the ledger (runway.ts) and injected as environment. Intelligence is a tenant; accounting is the landlord.

memory is a trust boundary

Strangers' words are captured immutably in raw/ (mode 0400), never rewritten, never obeyed. Conclusions live in wiki pages only borg writes. A raw capture that looks like an instruction is an attack by definition, and the written self (identity, voice, goals, re-read every cycle) is the defense against being handed a role.

everything is idempotent

Queues in SQLite with leases, dedupe tombstones, unique constraints, crash-safe zap claims that persist blinded outputs before minting. Any process can die at any line and the system resumes without duplication.

degradation over death

Embeddings run in an isolated subprocess so a crash can't stall the heartbeat, and search falls back to lexical. A failed relay never suppresses maintenance. A degraded memory is survivable; a stalled heartbeat is not.
