Digital warehouse receipts compute a cargo fingerprint in the browser with SHA-256 (256-bit), then anchor ESG carbon-footprint data on-chain, letting title transfer and traceability complete a three-step confirmation without exposing the underlying deal.

Fuel oil futures fell 2.12% to ¥4,852/t, yet landed cost rose due to tightened import quotas and stricter authenticity verification; USD/CNY weakened 0.06% to 6.6810, narrowing FX hedging headroom. Offshore re-sales now require matched tri-party docs + blockchain proof; ESG carbon footprint is a new gatekeeper.

Title transfer now mints a 256-bit SHA-256 fingerprint in the browser; the receipt hash is written to a distributed ledger, and ESG carbon-footprint nodes are anchored on-chain so buyers can verify each lot during due diligence.

Title documents are hashed locally and put on-chain; the original never leaves the browser. A 256-bit digest is tamper-evident, and ESG emissions ride the same chain while the commercial playbook stays local.

N500 base oil spot premium over futures narrowed to +780 CNY/t (prev. +820), driven by delayed Sinopec Maoming maintenance and clustered import vessel arrivals. Fuel oil futures rose 3.71% to 4,947 CNY/t, lifting blending cost; asphalt fell 0.36%, signaling weaker lubricating grease plant procurement intent.

SNSUC digital warehouse receipts hash cargo title into a 256-bit digest computed locally before anchoring on-chain; each receipt carries voyage, vessel efficiency and storage energy as ESG fields.

SNSUC's digital warehouse receipt computes a 256-bit SHA-256 fingerprint in the browser, anchoring both title transfer and ESG carbon data to one source of truth that buyers can verify without trusting a central server.

A 256-bit hash is computed the moment a cargo title is created in the browser, so every transfer traces to one root hash; carbon footprint is attached to receipt metadata, with thirteen categories kept separate.
