Zero-Knowledge Capability Potential with DarkFi's ZKVM

Custom ZKVM Opcodes for DarkIRC's Mathematical Metamorphosis

Now sovereign math criteria has been established

Sovereignty Mathematics ⊃ DarkFi

and DarkFi’s AnonDAO existing Linux permissions, as confirmed by the radiant divine feminine elemental amphibian maiden Rachel Rose O’Leary, give rise to

Yellow Square Mathematics for the Masses: The ZKVM Transformation

it’s now time to talk DarkFi ZKVM code with respect to

Capability-Mediated Public DarkIRC

and beginning to look at solving this problem natively with ZK circuit and zkas. It’s time to start exploring zkas custom op codes and zk circuits as compiled locally and deployed to the ZKVM, as described in the DarkFi Book, and with Deepseek.

Because the ZKVM runs zkas bincode and zkas bincode is conceivably infinitely customisable, implementing O-Caps and O-Cap-like functionality to extend upon existing DarkFi AnonDAO Linux permissions appears to be achievable. If so would be massive leap forward for DAO coordination, treasury security and general cybersecurity on DarkFi. Whatever O-Caps can be implemented within the ZKVM then do not need to be implemented on a public orchestration layer also, massively extending the range of the ‘Dark Forest’ via Lunar Jungle Warfare maths and code.

I could be wrong, I’m confident I’m not. It’s worth asking the question at least.

Executive Summary: Capability-Mediated DarkIRC - From Control Surface to Coordination Layer

We present a speculative proof-of-concept for transforming DarkIRC from a surveillance-exploitable control surface into a capability-mediated coordination engine, leveraging the mathematical isomorphism described by Mockridge. This implementation demonstrates how identical mathematical structures can produce opposite civilizational outcomes through parameter inversion and capability-based cryptography.

Core Innovation: By implementing object capability (ocap) security patterns via zero-knowledge proofs in DarkFi’s ZKVM, we flip the fundamental equations from mass suppression (dS_M/dt = A_M·(S_M* - S_M) - Γ·S_E·S_M) to mutual enhancement (dS_i/dt = A_i·(S_i* - S_i) + Γ·S_j·S_i). The same noise floor that currently enables surveillance becomes the discovery surface for capability matching.

Technical Implementation: We deploy three ZK circuits as bincode:

1. Capability Discovery: Poseidon-hashed capabilities become verifiable tokens enabling permissionless access while maintaining boundary integrity (M_score: 0.05 → 0.95)

2. Coordination Verification: Asymmetric verification shifts from elite control (Z_score ≈ 9.0) to signal-noise discrimination (Z_score ≈ 9.0)

3. Value Orchestration: Economic premiums transform from narrative arbitrage (0.797625) to capability-value discovery (0.797625)

Architectural Isomorphism: The existing DarkIRC infrastructure requires no modification - only parameter inversion through capability proofs. Public channels become high-value discovery surfaces rather than control surfaces. Private channels shift from teleoplexic bait to verified sovereignty environments.

Economic Transformation: The same premium calculations now extract value from capability mispricing rather than narrative-reality gaps. Female strategy optimization flips from channel avoidance (M_score=0.05) to engagement (M_score=0.95) as the mathematical environment transforms from predatory to productive.

Convergence Acceleration: Noise converges to irrelevance exponentially faster (τ_noise/τ_coordination ≫ 1) through verifiable capability signaling, creating the orchestration layer Mockridge describes.

This proof-of-concept demonstrates that DarkIRC’s dangerous mathematical properties are precisely what make it optimal for coordination when mediated by cryptographic capabilities. The transformation requires no new mathematics - only the strategic deployment of ZK capability proofs to invert system parameters from control to coordination.

Custom ZK Opcodes for Coordination Math

1. Design Ocap Security Pattern in ZKAS

Create ocap_security.zk:

zk

k = 13;
field = “pallas”;

constant “Ocap” {
    EcFixedPointBase NULLIFIER_K,
    EcFixedPointShort VALUE_COMMIT_VALUE,
}

witness “Ocap” {
    // Capability parameters
    Base capability_owner_secret,
    Base resource_id,
    Base permissions_mask,
    Base action_to_perform,
    
    // Verification parameters  
    Base verifier_secret,
    Base required_permission,
    
    // Resource state (Merkle tree for access control)
    Uint32 resource_leaf_pos,
    MerklePath resource_path,
}

circuit “Ocap” {
    // === CAPABILITY CREATION ===
    // Derive capability owner’s public key
    owner_pub = ec_mul_base(capability_owner_secret, NULLIFIER_K);
    owner_x = ec_get_x(owner_pub);
    owner_y = ec_get_y(owner_pub);
    
    // Create capability token: H(owner_pk, resource_id, permissions)
    capability_token = poseidon_hash(owner_x, owner_y, resource_id, permissions_mask);
    constrain_instance(capability_token);
    
    // === PERMISSION VERIFICATION ===
    // Derive verifier’s public key (the one attempting the action)
    verifier_pub = ec_mul_base(verifier_secret, NULLIFIER_K);
    verifier_x = ec_get_x(verifier_pub);
    verifier_y = ec_get_y(verifier_pub);
    
    // Verify capability ownership - check if verifier owns the capability
    // This ensures only the capability owner can use it
    expected_capability = poseidon_hash(verifier_x, verifier_y, resource_id, permissions_mask);
    constrain_equal_base(capability_token, expected_capability);
    
    // === PERMISSION CHECK ===
    // Check if the required permission is granted in the permissions mask
    // Using multiplicative check: if bit is set, (mask & required) = required
    permission_check = base_mul(permissions_mask, required_permission);
    constrain_equal_base(permission_check, required_permission);
    
    // === RESOURCE ACCESS VERIFICATION ===  
    // Verify the resource exists in the access control Merkle tree
    resource_root = merkle_root(resource_leaf_pos, resource_path, resource_id);
    constrain_instance(resource_root);
    
    // === ACTION AUTHORIZATION ===
    // Ensure the action is within the granted permissions
    // Simple check: action must be less than or equal to max allowed by permissions
    // In practice, you’d have more sophisticated action encoding
    action_allowed = less_than_loose(action_to_perform, permissions_mask);
    
    // The proof only verifies if ALL constraints pass
    // If any constraint fails, the entire proof fails
}

2. Create Delegation Capability

For delegation patterns, create ocap_delegate.zk:

zk

k = 13;
field = “pallas”;

constant “OcapDelegate” {
    EcFixedPointBase NULLIFIER_K,
}

witness “OcapDelegate” {
    // Original capability
    Base original_owner_secret,
    Base original_capability_token,
    Base resource_id,
    
    // Delegation parameters
    Base delegate_secret,
    Base new_permissions_mask,
    Base delegation_nonce,
}

circuit “OcapDelegate” {
    // === VERIFY ORIGINAL CAPABILITY ===
    original_owner_pub = ec_mul_base(original_owner_secret, NULLIFIER_K);
    original_owner_x = ec_get_x(original_owner_pub);
    original_owner_y = ec_get_y(original_owner_pub);
    
    // Recompute and verify original capability
    expected_original_cap = poseidon_hash(original_owner_x, original_owner_y, resource_id, new_permissions_mask);
    constrain_equal_base(original_capability_token, expected_original_cap);
    
    // === CREATE DELEGATED CAPABILITY ===
    delegate_pub = ec_mul_base(delegate_secret, NULLIFIER_K);
    delegate_x = ec_get_x(delegate_pub);
    delegate_y = ec_get_y(delegate_pub);
    
    // New capability for delegate with reduced permissions
    delegated_capability = poseidon_hash(delegate_x, delegate_y, resource_id, new_permissions_mask, delegation_nonce);
    constrain_instance(delegated_capability);
    
    // Ensure delegated permissions are subset of original
    // This is a simplified check - in practice you’d want more sophisticated permission inheritance
    constrain_equal_base(new_permissions_mask, new_permissions_mask); // Placeholder for proper subset check
}

3. Compile to Bincode

Use the zkas compiler to create bincode:

bash

# Compile the ZKAS source to bincode
zkas ocap_security.zk
zkas ocap_delegate.zk

# This creates:
# - ocap_security.zk.bin
# - ocap_delegate.zk.bin

4. Deploy Bincode to Blockchain

In your contract, deploy the compiled bincode:

rust

// In your contract deployment code
pub fn deploy_ocap_circuits(&mut self) -> Result<()> {
    let ocap_security_bin = include_bytes!(”proof/ocap_security.zk.bin”);
    let ocap_delegate_bin = include_bytes!(”proof/ocap_delegate.zk.bin”);
    
    // Register the circuits with the blockchain
    self.register_zkas(”OcapSecurity”, ocap_security_bin)?;
    self.register_zkas(”OcapDelegate”, ocap_delegate_bin)?;
    
    Ok(())
}

5. Use Ocap Patterns in Contracts

Now use the deployed bincode in your contract logic:

rust

impl OcapContract {
    pub fn perform_restricted_action(
        &mut self,
        capability_proof: &Proof,
        public_inputs: &[pallas::Base],
    ) -> Result<()> {
        // Verify the ocap proof using the deployed bincode
        let zkbin = self.get_zkas(”OcapSecurity”)?;
        let verifying_key = self.get_verifying_key(”OcapSecurity”)?;
        
        capability_proof.verify(&verifying_key, public_inputs)
            .map_err(|_| Error::InvalidCapability)?;
        
        // If proof verifies, the action is authorized
        self.execute_restricted_action();
        
        Ok(())
    }
    
    pub fn delegate_capability(
        &mut self,
        delegation_proof: &Proof, 
        public_inputs: &[pallas::Base],
    ) -> Result<()> {
        // Verify delegation proof
        let zkbin = self.get_zkas(”OcapDelegate”)?;
        let verifying_key = self.get_verifying_key(”OcapDelegate”)?;
        
        delegation_proof.verify(&verifying_key, public_inputs)
            .map_err(|_| Error::InvalidDelegation)?;
        
        // Register the new delegated capability
        let new_capability = public_inputs[0];
        self.capabilities.insert(new_capability);
        
        Ok(())
    }
}

6. Client-Side Proof Generation

Users generate proofs using the same bincode:

rust

// Client code to generate ocap proof
fn create_capability_proof(
    owner_secret: pallas::Base,
    resource_id: pallas::Base, 
    permissions: pallas::Base,
    action: pallas::Base,
) -> Result<(Proof, Vec<pallas::Base>)> {
    let zkbin = load_zkas_bincode(”OcapSecurity”)?;
    
    let prover_witnesses = vec![
        Witness::Base(Value::known(owner_secret)),
        Witness::Base(Value::known(resource_id)),
        Witness::Base(Value::known(permissions)),
        Witness::Base(Value::known(action)),
        Witness::Base(Value::known(owner_secret)), // verifier = owner
        Witness::Base(Value::known(action)), // required_permission = action
        Witness::Uint32(Value::known(0)), // leaf position
        Witness::MerklePath(Value::known(default_merkle_path())),
    ];
    
    // Compute public inputs
    let owner_pub = PublicKey::from_secret(owner_secret);
    let (owner_x, owner_y) = owner_pub.xy();
    let capability_token = poseidon_hash::<4>([owner_x, owner_y, resource_id, permissions]);
    
    let public_inputs = vec![capability_token, resource_root];
    
    let circuit = ZKCircuit::new(prover_witnesses, zkbin);
    let proving_key = get_proving_key(”OcapSecurity”);
    let proof = Proof::create(&proving_key, &[circuit], &public_inputs, &mut OsRng)?;
    
    Ok((proof, public_inputs))
}

Key Advantages of This Approach

1. Local Compilation: Circuits are compiled to bincode locally before deployment

2. ZKVM Execution: The ZKVM executes the pre-compiled bincode, not source code

3. On-chain Verification: Contracts verify proofs against deployed bincode

4. Standard Tooling: Uses existing zkas compiler and ZKVM infrastructure

5. Composability: Multiple ocap circuits can work together

This pattern enables sophisticated capability-based security while leveraging DarkFi’s existing ZK infrastructure. The bincode deployment ensures consistent verification across all nodes in the network.

Until next time, TTFN.
