Supply-chain provenance ledger for a US coffee importer

Specialty coffee importer, Seattle

Challenge
Buyers increasingly asked for verifiable origin and fair-trade documentation, but the paper trail from farm to warehouse passed through five intermediaries and could be neither verified nor easily shown to retail customers at point of sale.
Solution
AGS built a permissioned blockchain ledger recording custody transfers from farm cooperative through export, shipping and roasting, with a QR code on retail packaging that lets a customer see the verified chain. Each participant signs their own leg cryptographically.
Results
  • Provenance verified end-to-end for 100% of tracked lots
  • 5 supply-chain participants onboarded to the ledger
  • Retail partners citing verified origin in 3 new listing agreements

Smart-contract escrow for a UK property deposit platform

Rental deposit management platform, London

Challenge
Deposit disputes between tenants and landlords took weeks to resolve through a manual adjudication process, and both sides distrusted the platform's neutrality since it held the funds directly and made the final call.
Solution
We built a smart-contract escrow that releases funds only when both parties confirm, or after an adjudicator ruling recorded on-chain, so the resolution logic is transparent and auditable rather than a black box the platform controls.
Results
  • Average dispute resolution time down from 19 days to 6
  • Disputed-fund complaints to the ombudsman down 71%
  • Escrow contract audited with zero critical findings

Document integrity signing for a US title insurance firm

Title insurance underwriter, Texas

Challenge
Closing documents changed hands across title agents, lenders and underwriters over email, and a version-control mistake on a high-value commercial closing had already caused a costly dispute over which document version was authoritative.
Solution
AGS built a cryptographic signing and timestamping layer that hashes every document version onto a ledger the moment it is finalised, so any party can verify in seconds whether a document they hold matches the authoritative version.
Results
  • Document-version disputes down to zero since rollout
  • Verification time for a disputed document down from days to seconds
  • Signing layer processes 1,200+ closings a month

Loyalty token pilot for a Texas sports apparel brand

Sports apparel brand, Texas

Challenge
The brand's loyalty scheme was a points balance nobody checked. Marketing wanted to test whether collectible rewards tied to local team events would change behaviour, but without asking customers to install wallets, buy cryptocurrency or understand any of the underlying technology.
Solution
AGS built a pilot inside the brand's existing app: customers earn limited-run digital collectibles for purchases and event attendance, held in an embedded wallet created at sign-up with no extra steps. Collectibles unlock early access and discounts, and the ledger is verifiable without customers needing to care.
Results
  • Pilot ran with 5,000 customers over 3 months
  • Repeat purchase rate 18% higher than the control group
  • Under 1% of participants raised a support ticket

FAQ

Blockchain & Cryptography: questions, answered.

What does AGS build in blockchain and cryptography?

We build distributed systems with security as the starting point: smart contracts, blockchain architecture, and cryptographic protocols. Each is engineered and audited to the standard financial systems require, with encryption and key management designed to withstand real attack scenarios rather than pass a checklist.

How do you make sure a smart contract is secure before launch?

Every contract is security-audited from the first line of code. We write and test against known failure modes, then commission an independent security audit before funds ever touch it. After launch, ongoing monitoring watches for new exploits and protocol updates so security holds over time, not just at go-live.

Why does AGS treat security as the starting point rather than a final check?

Because a contract that handles real funds cannot be patched after an exploit. Our Discover step defines the threat model and consensus requirements up front, contracts are written against known failure modes, and an independent audit runs before anything goes live. Security is designed in, not bolted on later.

Can you match a blockchain design to our throughput and consensus needs?

Yes. Blockchain architecture starts by defining your throughput, consensus, and threat-model requirements, then matches network and consensus design to them. We do not default to one chain: the design follows what your workload actually needs, with cryptographic key management built for the attack scenarios you realistically face.
