Struct EntangledId 

pub struct EntangledId { /* private fields */ }

An Entangled Identity that binds a node’s ID to its software.

This structure represents a node identity that is cryptographically entangled with the binary it is running, preventing identity spoofing while running modified software.

Implementations

impl EntangledId

pub fn derive( public_key: &MlDsaPublicKey, binary_hash: &[u8; 32], nonce: u64, ) -> Self

Derive an entangled identity from its components.

The derivation formula is:

N_ID = BLAKE3(PK || binary_hash || nonce)

Arguments

• public_key - The ML-DSA-65 public key
• binary_hash - The BLAKE3 hash of the binary
• nonce - A unique nonce (e.g., timestamp or random)

Returns

A new EntangledId with the derived identity.

zkVM Compatibility

This method uses saorsa-logic for the core derivation, which is no_std compatible and can run inside zkVMs.

pub fn verify(&self, public_key: &MlDsaPublicKey) -> bool

Verify that this entangled ID matches the given public key.

This re-derives the ID from the public key and the stored binary hash/nonce, then compares with the stored ID.

Arguments

• public_key - The ML-DSA-65 public key to verify against

Returns

true if the ID was derived from this public key and the stored binary hash/nonce.

zkVM Compatibility

This method uses saorsa-logic for verification, enabling the same logic to be proven inside a zkVM.

pub fn verify_with_binary( &self, public_key: &MlDsaPublicKey, binary_hash: &[u8; 32], ) -> bool

Verify that this entangled ID matches the given public key and binary hash.

This is a stricter verification that also checks the binary hash matches.

Arguments

• public_key - The ML-DSA-65 public key to verify against
• binary_hash - The expected binary hash

Returns

true if the ID was derived from this public key, this binary hash, and the stored nonce.

pub fn id(&self) -> &[u8; 32]

Get the raw 32-byte identity.

pub fn binary_hash(&self) -> &[u8; 32]

Get the binary hash this identity is bound to.

pub fn nonce(&self) -> u64

Get the nonce used in derivation.

pub fn to_node_id(&self) -> NodeId

Convert to a NodeId for use in DHT routing.

The NodeId is simply the entangled ID bytes.

pub fn xor_distance(&self, other: &EntangledId) -> [u8; 32]

Calculate XOR distance to another entangled ID.

This is used for Kademlia routing.

zkVM Compatibility

This method uses saorsa-logic for the calculation, enabling consistent distance computation across native and zkVM contexts.

pub fn from_raw(id: [u8; 32], binary_hash: [u8; 32], nonce: u64) -> Self

Create from raw bytes (for deserialization/testing).

Warning

This bypasses the derivation process and should only be used for deserialization or testing purposes.

Trait Implementations

impl Clone for EntangledId

fn clone(&self) -> EntangledId

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
