Python SDK

Hash, anchor, and verify defense logistics records with a few lines of Python.

pip install s4-ledger

Three steps to immutable proof

1. Hash

Compute a SHA-256 hash of any defense record — a parts receipt, maintenance log, or CDRL.

from s4_sdk import S4SDK h = S4SDK.hash_data("record")

2. Anchor

Write the hash to the XRP Ledger. Confirmed in 3–5 seconds. Cost: $0.01 in $SLS.

result = S4SDK.anchor_hash(h) print(result["tx_hash"])

3. Verify

Re-hash the original and compare. Anyone can verify — no vendor required.

match = S4SDK.verify_hash( h, result["tx_hash"] )
