Proof-of-Performance (PoP)

Canonical Serialization (JCS)

We use RFC 8785 JSON Canonicalization Scheme to ensure deterministic bytes:

• UTF-8 encoding
• Lexicographic key order
• Minimal whitespace
• Standard number formatting (no NaN/Inf)

Let C(payload_no_nonce) be the JCS bytes.

Hash Construction

1hash = keccak256( C(payload_no_nonce) || nonce )

• nonce: 32-byte CSPRNG secret, revealed later.
• payload_no_nonce excludes the nonce field to avoid self-reference.
• Off-chain signature (optional) binds payload to publisher key.

Single vs. Batched Commits (Merkle)

• Single: Store hash directly.
• Batch: Compute leaf L_i = keccak256( C_i || nonce_i ) , build Merkle tree, store root R.
• Reveal passes (payload_i, nonce_i, proof_i) ; contract verifies leaf and path to R.

Reveal Windows & Anti-Withholding

• minRevealAt prevents immediate leakage; maxRevealAt enforces timely disclosure.
• Missed reveal ⇒ Expired flag (analytics penalize).

Publisher Identity & Signatures

• Metadata stores publisher address.
• Optionally include sig (ECDSA secp256k1) over C(payload_no_nonce) in reveal payload; SDK verifies off-chain.
