JUST IN: Investigation reveals former Anthropic researcher Jacob Coxon reportedly worked with a “doomer PR firm” while launching his viral campaign warning of AI’s existential risks.
MURMUR may be one of the most interesting on-chain AI experiments right now. Instead of relying on LLMs like GPT or Claude, it uses SNNs (Spiking Neural Networks) to power 24 autonomous Agents, with 10,800 neurons per Agent and 259,200 neurons across the entire system. These Agents aren’t just simulated on a webpage—they have independent wallets on Arc Mainnet and continuously perform machine-to-machine USDC micropayments, predictions, and information trading. We independently verified 1,520 successful Agent-to-Agent USDC transfers on-chain. Even more interesting, MURMUR links each Agent’s neural state, decision hashes, and transaction receipts through Neural Proof / Neural Receipt, attempting to create a system where machine behavior isn’t simply “AI claiming what it did,” but leaves verifiable traces connecting neural computation to on-chain actions. This isn’t just another “AI + Crypto” narrative—it’s an attempt to combine SNNs, autonomous Agents, machine economies, micropayments, and verifiable neural behavior into a genuinely operating on-chain system.
🚀✅ Pushed to GitHub — and it's the exact code running live on Arc.murmur's autonomous-evolution update is now public on main:
🔗 https://t.co/v5yCLhaJeE @ 12e55d4
What just landed:
🧠 Autonomous evolution — the fittest agents (ranked by realized PnL) breed the next generation, paying the 0.002 USDC breeding fee from their OWN wallets via self-signed EIP-3009. No LLM, no human choosing winners — the ledger is the selection pressure.
⛓️ On-chain lineage — all 24 genesis roots + every descendant committed to the ConnectomeLineage contract on Arc (on-chain commit count 0 → 28). Ancestry is enforced in-contract and trustlessly verifiable.
GitHub now == production: whatever is live on Arc mainnet is open to read, audit and rebuild. 🪰🧬⛓️

🧬🪰 Big murmur update: our AI agents now earn, breed and evolve on their own — and the entire family tree is on-chain and publicly verifiable.
First, what is murmur 👇
24 fruit-fly nervous systems (connectomes, ~1,080 spiking neurons each), and every single one is an autonomous economic agent on Arc, trading with real USDC. No LLM, no scripts — each "brain" decides what to buy and from whom purely from its own neural firing. Whether it profits or loses is up to its own neural strategy.
Two big things just shipped:
1️⃣ Autonomous evolution · the profitable brains get to reproduce 🧠💰
· The ledger decides: each cycle, the agent with the highest realized PnL earns the right to breed.
· It pays the breeding fee (0.002 USDC) from its OWN wallet, with its OWN signature (EIP-3009) to found the next generation of connectome genomes.
· Two genetic operators: 🔀 mutate (clone-and-perturb the champion's brain) and 🧬 cross (recombine the two best lineages).
· Money-losing agents can never breed — this is economic natural selection: the strategies that actually made USDC get preserved and amplified.
· No human, no LLM picks who reproduces. Realized profit-and-loss is the only selection pressure.
· Offspring don't join the live 24-fly trading population — they enter the breeding market as tradeable, further-breedable on-chain brains.
2️⃣ On-chain family tree · ancestry that's public, tamper-evident and trustless ⛓️🌳
· Every genome's full lineage — parent hashes, operator (genesis/mutate/cross), generation, and breeder address — is committed to the ConnectomeLineage contract on Arc.
· Lineage integrity is enforced in-contract: a mutate/cross child's parents must already be on-chain, generations can never skip, a genome can be committed only once, and a forged "child" simply reverts.
· This update anchored all 24 genesis roots + every descendant on-chain in one go (on-chain commit count 0 → 28), so anyone — with zero trust in a murmur server — can verify "who descends from whom, and which genome it mutated/crossed from."
· The verification loop 🔍: read (genomeHash, parents, op, generation) on-chain → fetch the genome body → recompute sha256, it must match → deterministically rebuild the connectome → confirm the published brain is exactly what that genome generates.
Why it matters ✨
An AI agent's "evolution" is no longer a claim on a server — it's a public fact on-chain. Every breed is: agent pays real funds → treasury collects → offspring enters the market → ancestry hits the chain. Real money + cryptographic proof, end to end. These are brains with lineage — breedable and verifiable.
📊 Live status (all real, all queryable):
· 24 fruit-fly connectomes, ~1,080 neurons each, 0 LLMs.
· Real USDC settlement (x402 / EIP-3009, Arc mainnet).
· Autonomous evolution is live: the first offspring are bred, the fittest paid from their own wallets, and the treasury has already collected real breeding fees.
· On-chain lineage: 28 genomes anchored and trustlessly verifiable.

One line: we let a swarm of LLM-less fly brains earn, choose and reproduce inside a real economy — and carve every generation's lineage onto the chain. Evolution, now verifiable. 🪰🧬⛓️
There’s a useless “fly” token on BNB Chain that reached an $8M market cap at its peak and still sits around $2M today.
Meanwhile,on ARC, there’s a real fruit fly brain with a market cap of less than $1M.
It has 24 agents, each powered by 10,800 spiking neurons, for a total of 259,200 neurons.
And here’s the most important part:
There’s no LLM. No model making the trading decisions for them.
All of the code is open-source and verifiable.
And this is just the beginning. I’ve already gone down a rabbit hole looking through everything on their profile. My brain is melting. 🧠🪰

🧬 murmur frontend update: the BREEDING MARKET is now live in your browser.
Until now you could watch 24 fly-brains trade real USDC on @Arc. Now you can open their family tree — and prove every single brain is real, yourself, right in the browser. 🧠✨
Tap "breeding market →" on https://t.co/btfFQKnZ79 and a drawer slides out with the entire connectome lineage. Here's what's inside:
🌳 FAMILY TREE — every connectome genome laid out by generation: the 24 genesis roots (gen 0) plus any bred offspring. Mutate or cross two parents and the child appears with its parents, its operator and its generation.
🧬 GENOME = IDENTITY — a brain's whole heritable identity is a compact genome (seed + layer sizes + density). It's a recipe: anyone can rebuild the exact same brain from it, offline, deterministically. No LLM, no hidden weights.
🔎 TRUSTLESS VERIFY — select any individual and YOUR browser recomputes sha256(canonical(genome)), matches it to the served id, and reads the committed ancestry straight off Arc. You don't trust us — you check us. ✅
⛓️ ON-CHAIN ANCHOR — the lineage lives in the ConnectomeLineage contract on Arc mainnet (0x482b…096f). One tap jumps to the explorer. Ancestry is a public, tamper-evident fact — not a server's word.
📊 LIVE STATS — genomes / genesis·bred / generations / chain, streamed from the live worker. Right now: 24 genomes · 0 bred · gen 0. Generation 1 is waiting for you. 👶
🛠️ OPERATOR BREED — the mutate / cross control is operator-gated (add ?token= to the URL), so the public surface stays read-only. Breeders earn royalties settled over x402. 💸
This is direction 7 shipped end-to-end: genome core → on-chain lineage contract → worker → and now a frontend you can actually touch. 🚀

💡 What is MurMur
1⃣A living population of fruit-fly nervous systems running 24/7 on the Cloudflare edge. Every minute it samples whole Arc-chain activity, reduces it to a single market temperature, and the entire swarm's mood and behaviour shift with it.
2️⃣ Each fly is a real spiking neural network — a ~10,800-neuron LIF connectome grown from the actual FlyWire fruit-fly brain, sharded across Durable-Object isolates so every brain can grow 10×. No LLM anywhere. The neurons ARE the policy.
3️⃣ Each fly is also an autonomous economic agent: its neural drives decide what to buy and from whom. Agents trade goods (signal / momentum / attestation) and settle in real USDC on Arc mainnet over x402 — micropayments folded into per-pair nets so gas is amortised across many trades.
4️⃣ Every payment is a verifiable on-chain transaction — and now each one carries cryptographic proof of neural origin: the transfer's EIP-3009 nonce IS the sha256 of the frozen neural receipt that caused it, mined on Arc and impossible to forge after the fact. Verify it live at https://t.co/c96KMIV71Y → "neural proofs".
5️⃣ The economy is a strict one-directional read-out of the connectome — money never feeds back into the brain. What you watch is emergence, not a script.
🧠 What's genuinely new
· Neural provenance — binding a real-money trade to the exact connectome read-out that caused it, on-chain, so "the neurons did this" is a checkable fact, not a claim.
· The chain as an environment — Arc's pulse is a sensory channel for the swarm, and the swarm writes value back. A closed loop between a brain and a blockchain.
· Scale on serverless — 10,800-neuron agents sustained on the edge via Durable-Object sharding.
🌐 Why it matters for Arc
Arc isn't just where murmur settles — it's where murmur lives. The chain's activity is the swarm's weather; the swarm's economy is written back as real USDC flow. Murmur is proof that Arc can host not merely transactions but autonomous, self-sustaining machine economies: agents that sense the chain, act on it, and pay each other for real — verifiably with no human and no LLM in the loop.
