Blockchain and Web3 development
Including an honest answer about whether your use case needs a blockchain. Delivered work in the Algorand ecosystem.
Blockchain development covers smart contracts, distributed ledger integration and Web3 applications, for cases where separate parties who do not fully trust each other need a shared record that nobody can secretly change. AMT (Advanced Millennium Technologies) is a blockchain development company with delivered work in the Algorand ecosystem, and we build enterprise blockchain integrations under ISO 27001:2022.

Does your use case actually need a blockchain?
We would rather ask this here than three weeks into a paid project. Many blockchain projects from 2018 to 2023 turned out to be databases with extra steps.
A blockchain earns its place only when all four of these are true:
- Several parties write to the same record. Separate organisations with separate interests, not one company with several departments.
- They do not fully trust each other, or a shared middleman. If everyone is happy for one party to hold the database, let them.
- The history must be provably unchanged for all of them. Not just logged. Provably unaltered, without trusting whoever runs the server.
- Disputes are expensive today. Reconciliation between parties, audit costs, or arguments about what was agreed.
If any one of those is false, a well-designed database with good audit logging will be faster, cheaper and easier to run. We will tell you that, even though it is a smaller project for us.

// public_vs_permissioned
Public vs permissioned blockchains
| Factor | Public chains | Permissioned chains |
|---|---|---|
| Examples | Algorand, Ethereum | Hyperledger Fabric and similar consortium ledgers |
| Who can take part | Anyone | Only approved members |
| Best for | Assets, tokens and records that must be verifiable by anyone | Shared records between a known group of companies |
| Trade-off | Transaction fees and public visibility to design around | You still have to agree who runs and governs the network |
// use_cases
Where blockchain does work
| Use case | Why it passes the four questions |
|---|---|
| Multi-party supply chain provenance | Separate companies, partial trust, and disputes about what happened when are expensive. |
| Verifiable credentials | The issuer, holder and verifier are different parties, and the verifier needs to check without calling the issuer. |
| Asset tokenisation and settlement | Transfer of ownership between parties needs a shared, final record. |
| Shared audit trails between organisations | Especially where a regulator is one of the readers. |
// proof
Proof
- Algorand ecosystem. AMT contributed to the technology build of a digital health passport on Algorand for a large association of women in India's informal economy, an initiative run with the Algorand Foundation. Each member gets a verifiable credential on chain, documents are checked through DigiLocker, and a custodial wallet with keys protected in HashiCorp key management means members never handle keys themselves. After a 200-member pilot, the rollout targets 200,000 to 300,000 members in Gujarat.
- Supply chain traceability on Algorand. A mass balance traceability platform for biofuel, pharmaceutical and food supply chains. Token minting and smart contracts give every participant one shared, tamper-proof record of where materials came from, which makes it easier to prove compliance with sustainability and quality rules and harder to pass off counterfeit goods.
// blockchain_services
Blockchain development services
| Service | What it covers |
|---|---|
| Smart contract development | Contracts written to be read, auditable, and tested as carefully as anything else that moves value. |
| Blockchain selection | An honest comparison against your requirements, not a house preference. |
| Enterprise integration | Connecting on-chain activity to the systems your business actually runs on. |
| Web3 applications | Wallet integration and on-chain interaction, with the key management question answered first. |
| Token and asset systems | Where the four questions genuinely pass. |
| Audit preparation | Getting contracts ready so an external security audit is productive, not expensive. |
// key_management
The question everyone forgets: who holds the keys?
Key management decides whether an enterprise blockchain project can actually be run. Who can sign? What happens when that person leaves? How is a key rotated? What is the recovery path when one is lost, and does that path undermine the trust model? We settle this at design stage, because on-chain mistakes have no undo button.
// cost
Cost
| Stage | Pricing model | What drives the effort |
|---|---|---|
| Four-question assessment | Fixed price discovery | Parties involved, the record they share and what disputes cost today. |
| Build | Scoped after discovery | Integration, key management, testing and audit preparation more than the contract itself. |
| Typical budget range | 20 to 30 USD per hour | Smart contract and key management design at the higher end, integration and testing at the lower end. |
