TimeLayer Open Verifier

A small standard-library Python verifier for TimeLayer public /live/canon receipts.

Website placeholder: timelayer.io

What This Verifies

The verifier fetches http://<node>:47821/live/canon, parses the JSON receipt, and checks the fields exposed by the real /live/canon schema.

A receipt is VERIFIED when all required checks pass:

• canon_holding is true.
• result is PASS or status is PASS.
• node_id exists and is not empty.
• timestamp_utc exists and is not empty.
• peer_pairs_checked exists and is an integer greater than 0.
• pairs[] exists and contains at least one pair where canon_holding is true.

The verifier does not check snapshot_sequence_number or staleness_seconds in /live/canon. Those fields are not part of the current /live/canon response surface and belong to other status surfaces when available.

Installation / Requirements

• Python 3.6+
• No third-party dependencies

Usage

Verify one node:

python3 verifier.py --node 128.140.100.56

Verify all built-in public nodes with the default threshold of 4 verified nodes:

python3 verifier.py --all-nodes

Verify all built-in public nodes with an explicit threshold:

python3 verifier.py --all-nodes --min-verified 4

Public Nodes

Node	IP
Web4	128.140.100.56
Asia	5.223.66.154
Liquid	46.224.191.167
USAE	5.161.247.5
node5	5.78.114.42
node6	204.168.227.86

Current Expected Status

The current open verifier threshold is 4/6 verified nodes in all-node mode. Web4, Asia, Liquid, and USAE are expected to verify when their canon_holding remains true.

NODE5_NODE6_CANON_STABILIZING: node5 and node6 may return NOT_VERIFIED while their canon windows stabilize after key registry distribution. This is expected for newly added nodes and is reported explicitly rather than treated as a publication blocker when at least four nodes verify.

Example Output

Single node mode prints the fetched receipt followed by a verdict:

NODE custom 128.140.100.56
URL http://128.140.100.56:47821/live/canon
...
VERDICT VERIFIED

All-node mode prints a compact table and threshold summary:

SUMMARY verified_count=4/6
SUMMARY canon_holding_count=4/6
SUMMARY min_verified=4
SUMMARY threshold_pass=YES
