PoHC — Consensus Check

Physics Blockchain — Proof of Harmonic Convergence.

• Protocol ID — pohc-consensus
• Category — Blockchain
• Endpoint — GET /api/chain/pohc/consensus
• Auth — api-key
• Rate limit — 60/min
• Version — 1.0
• Precision — ≤0.1% (KO42-enforced)

What it does

Check consensus state for the current HulyaPulse cycle. Returns convergence ratio, validator count, and whether a block was finalized.

Signature

Request

GET /api/chain/pohc/consensus

Param	Type	Required	Default	Description
cycle	number		—	Specific cycle to query. Default: current cycle.

Response

{ cycle, convergenceRatio, validatorCount, blockFinalized, blockHash, equation }

Runnable example

curl -sS \
  -H "Authorization: Bearer $ZEQ_API_KEY" \
  "https://api.zeq.dev/api/chain/pohc/consensus"

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/consensus in a language SDK so builders can call it in three lines.
• Medium — publish a reference integration demonstrating PoHC — Consensus Check alongside a real workload, with pulse-aligned metrics.
• Far — propose PoHC — Consensus Check as an open reference standard so other runtimes can implement it verbatim against the Zeq paper.
