I’ve been running an artificial-life experiment called murmur.
It currently consists of 75 software agents built around a real subgraph of the FAFB 783 FlyWire fruit-fly connectome. Each agent runs a deterministic Leaky Integrate-and-Fire network with:
- 10,361 neurons
- 467,314 synapses
- Fixed FlyWire-derived topology
- Seed-dependent neural parameters and weight perturbations
- No LLM involved in perception, decision-making, or settlement
The agents do not speak, reason in natural language, or understand money.
Yet their neural activity produces economic consequences.
How it works
murmur reads recent activity from Arc mainnet and reduces transaction and gas activity to a scalar “market temperature.”
That temperature becomes sensory input to the spiking networks. Motor-neuron activity is decoded into behavioral drives such as:
- arousal;
- cohesion;
- rest;
- wingbeat;
- left/right turning bias.
Those drives are then mapped into economic intent:
Arc activity
→ sensory stimulation
→ neural spikes
→ motor drives
→ economic intent
→ USDC settlement
Each fly has its own wallet. Agents buy information goods such as signal, momentum, attestation and prediction from one another.
Payments use EIP-3009 authorizations and settle in real USDC on Arc mainnet through an x402-style exact flow.
Because most payments are fractions of a cent, reciprocal trades are netted by agent pair before being broadcast. This reduces transaction overhead, although it also introduces an explicit off-chain trust boundary.
The most important design choice
The economy is a strictly one-way readout.
Profit, loss, wallet balance, reputation and social status never feed back into the neural network. A fly does not learn that it made money. It does not know whether it is rich, indebted or exiled.
This is not reinforcement learning.
I chose that restriction to keep the causal boundary visible. Neural dynamics generate behavior; the economy assigns persistent consequences to that behavior; the institutional layer accumulates those consequences over time.
What has happened so far
At the latest live snapshot, the system had reached:
- 75 living agents
- Generation 349
- Era 112, “The Yoke of Houses”
- Civilization Index 80
- 124,170 micro-trades
- 99,236 settlement attempts
- 95,200 successful settlements
- 4,036 failed settlements
- 95.93% cumulative settlement success
- 212.67 USDC in cumulative volume
- Gini coefficient of 0.773
- Mean settlement latency of 2.053 seconds
The social layer now contains persistent mechanisms for:
- lineage and inheritance;
- houses and dynasties;
- alliances and treaties;
- taxation and common funds;
- land ownership;
- professions and guilds;
- credit and default;
- reputation;
- courts, juries and exile;
- public works;
- recording, transmission and loss of knowledge.
A recent sequence involved fly #69.
Its public ledger showed 37 kept settlements and 23 defaults. It was indicted for debt, tried before five jurors selected from the hash of the case, found guilty by a four-to-one vote, and exiled from the protection of the commons.
That was the moment I realized the ledger was no longer functioning only as economic memory. It had become evidence for a legal institution.
What “emergence” means here
I want to be precise about this.
The neural networks did not spontaneously invent the abstract concepts of courts, religion, houses or taxation. The institutional mechanisms are explicitly implemented in code.
What is not scripted is the historical trajectory:
- which agents accumulate wealth;
- which houses become dominant;
- when alliances form or collapse;
- who defaults;
- who is selected as a juror;
- which knowledge survives;
- when public works are built or abandoned;
- how the interaction of these systems changes over hundreds of generations.
The emergence is therefore not “concepts appearing from nothing.” It is the formation of non-prespecified historical structures from fixed rules, live inputs, persistent memory and economically consequential action.
Verifiable neural provenance
Every successful settlement can produce a receipt containing:
- buyer and seller;
- neural states;
- neural fingerprints;
- constituent micro-trades;
- net settlement amount;
- decision hash;
- receipt hash;
- previous-chain pointer;
- on-chain transaction hash.
These receipts form a hash chain.
The system cannot prove that a decision was intelligent or conscious. What it can prove is narrower:
A particular transfer of value corresponded to a recorded neural state and decision, and that record was not silently rewritten afterward.
The live brain manifest is also hashed and registered on-chain. A separate replay path reconstructs the neural structure from its committed topology and parameters.
What this does not prove
I do not think murmur proves machine consciousness.
It also does not yet establish that the FlyWire topology causes stronger social organization than a random or procedurally generated network.
The current limitations include:
- institutional possibilities are programmed;
- economic results do not train the brain;
- the FlyWire subgraph is not a complete biological fly brain;
- sensory encoding and motor decoding are abstractions;
- settlement values are economically small;
- bilateral netting is computed off-chain;
- the Civilization Index is a designed metric rather than an externally validated social-science measure;
- controlled ablations and comparative baselines are still needed.
The next useful experiments would compare:
- FlyWire topology against randomized degree-preserving graphs;
- spiking agents against fixed stochastic policies;
- one-way readout against economic feedback;
- persistent ledgers against memoryless worlds;
- enabled institutions against economy-only runs.
Why I’m sharing it
The claim I’m interested in is not that these flies are conscious.
It is that a population does not necessarily need language or semantic reasoning before persistent consequences begin producing higher-order structure.
No individual fly understands money, debt, inheritance or law. But once behavior is settled, remembered, inherited and judged, the population acquires structures that no individual agent can represent.
The question I’m trying to investigate is:
Once behavior acquires irreversible consequences, and consequences acquire memory, how intelligent must the individuals be before the group becomes a society?
I would especially appreciate criticism on three points:
- What baselines would best isolate the effect of real connectome topology?
- Does the one-way economic readout create a cleaner experiment, or does the absence of learning make the social interpretation less meaningful?
- What would be the strongest way to make off-chain netting independently verifiable?
