Functions

func OwnerRoot added in v1.4.11 

func OwnerRoot(o owners) [32]byte

OwnerRoot is the CANONICAL Go definition of the execution_root UTXO leaf's owner_root field. It is the authority the GPU state-snapshot producer MUST match (the GPU/CPU kernels treat owner_root as a host-supplied input — xvm_gpu_layout.hpp documents its intent as "keccak over sorted owner address set + threshold" but does not derive it; this is where that derivation is pinned).

owner_root = keccak256( 

threshold_u32_le ‖ key_count_u32_le ‖ key[0] ‖ key[1] ‖ … ‖ key[k-1] )

where:

  • threshold is the output's N-of-M spend threshold (binds the M-of-N policy, per the layout's "+ threshold");
  • key_count is the number of owner keys, little-endian u32 — a length prefix so two owner sets that differ only by a key-set/threshold framing can never collide (no ambiguous concatenation);
  • each key is an owner key in canonical ascending byte order: for an address-keyed output the 20-byte secp256k1 address; for a bls attestation output the committee public key. The order is the same sorted-and-unique order the output's own Verify enforces, so the preimage is deterministic and independent of the order keys happened to be listed in.

The keccak256 is Ethereum Keccak-256 (the same hash xvmroot/the GPU use for every leaf preimage), keeping owner_root in the one hash family the whole execution_root is built from. Integers are little-endian to match the kernel's absorb_u32.

Locktime is NOT folded into owner_root: the UTXOLeaf binds Locktime in its own dedicated field (matching the GPU UTXO struct, which carries locktime and owner_root separately), so binding it here too would be redundant. Threshold is bound in BOTH owner_root and the leaf's Threshold field, exactly as the GPU struct carries threshold both inside the host-computed owner_root and as a standalone field.
