PoHC — Proof of Harmonic Convergence

Physics Blockchain — Proof of Harmonic Convergence.

• Protocol ID — pohc-validate
• Category — Blockchain

• Auth — api-key
• Rate limit — 30/min
• Version — 1.0
• Precision — ≤0.1% (KO42-enforced)

What it does

Submit a physics computation for block validation. Validators solve the same equation simultaneously on HulyaPulse cycles — solutions must converge within tolerance. No hash puzzles. Real physics.

Signature

Request

POST /api/chain/pohc/validate

Param	Type	Required	Default	Description
equation	string	✓	—	Physics equation derived from transaction data.
solution	number	✓	—	Validator's computed solution.
syncCycle	number	✓	—	HulyaPulse cycle this solution was computed for.
validatorId	string	✓	—	Validator's ZID.

Response

{ accepted, convergenceRatio, validatorsAgreed, blockCandidate }

Runnable example

Integrate

1. Consensus trigger — use Harmonic Convergence pulse phase as the block-seal condition.
2. Audit trail — write ledger entries with zeqond plus error_pct for provable determinism.
3. Fork detection — split fork handling on pulse-phase disagreement to drop stale branches fast.

Seeds

• Near — wrap /api/chain/pohc/validate in a language SDK so builders can call it in three lines.
• Medium — publish a reference integration demonstrating PoHC — Proof of Harmonic Convergence alongside a real workload, with pulse-aligned metrics.
• Far — propose PoHC — Proof of Harmonic Convergence as an open reference standard so other runtimes can implement it verbatim against the Zeq paper.
