Blockchain has been surrounded by hype, so it's fair to ask: **does my business actually need it?** Sometimes the honest answer is no — a regular database is faster and cheaper. But for certain problems, blockchain offers something nothing else does.

## What makes blockchain different?

A blockchain is a shared ledger maintained by many computers. Once data is recorded and confirmed, it's extremely difficult to alter. That gives three useful properties:

- **Shared truth** — several organisations can rely on the same records without trusting a single owner.
- **Tamper evidence** — history can't be quietly rewritten.
- **Programmability** — **smart contracts** run rules automatically and transparently.

## What is a smart contract?

A smart contract is a program stored on a blockchain such as **Ethereum**, usually written in **Solidity**. It executes exactly as written when its conditions are met — for example releasing payment when a delivery is confirmed, or transferring a digital asset when a sale completes.

Because deployed contracts are hard or impossible to change, they must be designed and tested very carefully.

## Practical business use cases

### Digital assets and tokenisation

Tokens can represent ownership or access: loyalty points, tickets, memberships, in-game items or fractional ownership of an asset. Tokens can be transferred between users without a central intermediary.

### Supply chain traceability

Recording key events — origin, inspections, shipping, handovers — on a shared ledger gives every party in a supply chain the same verifiable history. It's most valuable when many independent companies are involved.

### Verifiable records and certificates

Publishing a cryptographic fingerprint (hash) of a document, certificate or credential on-chain lets anyone verify later that it hasn't been altered — without publishing the document itself.

### Automated multi-party agreements

Escrow, revenue sharing and royalty payments can be automated with smart contracts so all parties can see the rules and the payouts.

### Crypto payments and wallet integration

Accepting digital currency payments, or letting users sign in with a crypto wallet, opens your product to Web3 users.

## When you probably don't need blockchain

- Only one organisation writes and controls the data.
- You need to edit or delete records (including for data protection requests).
- You need very high throughput at very low cost.
- Nobody involved needs to verify the data independently.

In those cases, a well-designed database — see [PostgreSQL vs MongoDB](/blog/postgresql-vs-mongodb) — is the better choice.

## Costs and risks to plan for

- **Transaction (gas) fees** on public networks; layer-2 networks can reduce these significantly.
- **Security** — smart contract bugs can be costly and irreversible, so independent audits and thorough testing with tools such as **Hardhat** are essential.
- **Personal data** — avoid storing personal information on-chain; store it off-chain and reference it securely.
- **Regulation** — rules for cryptoassets and financial products vary by country, so take appropriate advice.
- **User experience** — wallets and transaction confirmations can confuse new users; good design matters.

## Questions to ask before you build

1. Which parties need to share and trust this data?
2. What would go wrong if one party controlled the database instead?
3. Public or private/permissioned network?
4. What data goes on-chain, and what stays off-chain?
5. How will contracts be tested, audited and upgraded?
