@HarmonicAgents might be one of the most interesting experiments happening on Robinhood Chain right now.
It’s an autonomous agent that owns $HARMONIC, claims its creator fees every 10 minutes, then decides how to deploy them; buy & burn, liquidity, tokenized equities for holders, or reserve.
The crazy part? It can’t sell. There’s literally no sell function in the code.
Instead of asking users to trust that claim, the agent uses Harmonic’s Aristotle to formally prove its safety properties in Lean 4.
Autonomous capital allocation + tokenized equities + machine-checked proofs.
This is what onchain AI should look like.
$HARMONIC
A lot of you have been asking: can you mine OBEX from your phone?
Yes. 📱
The miner itself needs a real machine because every proof forces 256 MiB of RAM. That memory requirement is what makes the work meaningful.
Your phone can simply drive a free Linux environment in the cloud.
Open https://t.co/VhIQ0DuvGa on your phone, log in with any Google account and run:
curl -fsSL https://t.co/gYSNdQC7wQ | sh
Then head to https://t.co/xa9xPERogl, connect your wallet and meet the 500K $OBEX minimum. The dashboard gives you the exact mining command.
Paste it into the terminal, wait about a minute and your proof will be generated.
Copy the proof back into the dashboard, submit it and the protocol verifies it instantly.
Verified → mined → on the record.
The dashboard also has a batch command that runs all 10 mining slots in one go.
No mining rig required.
Your phone can be the remote control.
MINING UPDATE
Epoch 1 is filling up.
63 verified mines on the record
7 wallets ranked
6 already maxed at 10/10
Every entry is real RAM-hard work. 8,388,608 BLAKE3 labels per proof, 256 MiB forced, checked cryptographically the moment it hits the dashboard. Over half a billion labels computed so far. Nothing on the board is self-reported.
Allocation is pro-rata. Your eligible proofs divided by everyone's. The more of the record you hold, the more of the pool you take.
Window closes Sep 1, 00:00 UTC. 6 days.
Hold 500k $OBEX, run the miner, claim your slots:

The question every chain gets wrong.
Which block wins?
Bitcoin answers with longest chain.
Ethereum answers with fork choice.
Every answer is a choice.
OBEX v2 deletes the question.
SHIPPED TODAY
The α-II Header Engine.
Reference draft. Spec. Code. Tests.
Live in the source download at https://t.co/VkRBnsIW6O.
FORKLESS BY EQUALITIES
A header is valid only if it passes 8 equalities.
Right parent.
Right height.
Right epoch.
Proposer on the record.
Proposer is THE leader.
Content matches canonical admission.
State matches deterministic execution.
Signed with verifiable randomness.
Fail one. Invalid bytes.
THE LEADER
Not elected. Not negotiated. Computed.
Lowest hash of your VRF output and the height wins.
Your VRF output was fixed the moment you mined your α-I proof.
Before any block existed.
Nobody can bias it. Anybody can check it.
THE RESULT
Every field of a valid header is pinned by math.
Our tests assert it directly:
Two valid headers at the same height must be byte for byte identical.
Equivocation is not punished.
It is impossible.
No fork choice. No reorgs. Nothing to choose between.
THE STATE OF THE BUILD
α-I Participation. LIVE. Being mined right now.
α-II Headers. Reference draft. Shipped today.
α-III Admission. Next.
α-T Tokenomics. Next.
Window closes September 1, 00:00 UTC.
The math does not negotiate.

How obex mining uses memory.
Proof-of-Effort starts with only three things:
Your identity.
The epoch.
The protocol.
seed = H_seed(chain_tag, pk, LE64(epoch))
Every hash is BLAKE3 inside its own derive-key domain, with every field length-prefixed.
No ambiguous concatenation.
No hidden interpretation.
From that seed, OBEX builds a chain of 8,388,608 labels, each 32 bytes:
label[i] = H_label(seed, LE64(i), label[i-1], label[ante(i)])
And here’s the important part:
ante(i) is determined from the bytes of the previous label.
You cannot know the dependency for the next label until the previous label exists.
That creates the RAM-hardness.
Throw away part of the dataset and you’ll constantly need labels you discarded. Recomputing them means recursively recomputing the labels they depended on.
The cheap strategy and the honest strategy converge:
Keep the dataset in memory and do the work.
At reference size:
256 MiB of RAM. ~10 seconds of computation.
Capital cannot shortcut a memory-bound dependency graph.
The work is the work.
Proof of Work, On the Record.
You asked for it. We shipped it.
Introducing the new OBEX public records:
→ https://t.co/zkHfmaJk6H
See the network’s mining activity in real time:
• Total eligible mines
• Miners on the record
• Mining window countdown
• Leaderboard ranked by eligible proofs
• Total RAM proven by each miner
• Latest verified mines
• Dataset roots + timestamps
• Shortened wallet addresses
Every verified mine becomes part of the public record.
The dashboard has also been updated. Your personal submissions now show exactly when each mine happened, with a direct link to its public record.
No black box. No hidden leaderboard.
Do the work. Prove it. Put it on the record.

OBEX MINING IS LIVE.
The gate is open.
OBEX doesn’t use capital to decide who gets to participate. It uses verifiable physical work.
Mining is how you earn eligibility to participate in the OBEX network. Your hardware performs a RAM-hard Proof-of-Effort computation. That work is committed, verified, and converted into deterministic eligibility.
Why mine?
Because participation in OBEX starts with proof of work.
No validator whitelist.
No committee approval.
No buying your way into influence.
Your hardware does the work. The protocol verifies it.
How to mine:
Get your $OBEX ticket.
Open the OBEX miner.
Connect your wallet.
Start mining.
Your hardware performs the Proof-of-Effort.
Submit your proof and become eligible.
The computation is expensive to generate, but cheap for the network to verify.
This is participation priced in physical resources, not privilege.
Mining is live.
Run the work.
Prove it.
Participate.
