We have built blockchain projects since 2019. Most of the pitches we hear do not need blockchain. A regular database would be faster, cheaper, and simpler. But there are three categories where decentralized ledger technology genuinely solves a problem that centralized systems cannot.
## 1. Multi-party settlement
When multiple organizations need to agree on the state of a shared ledger without trusting a single operator, blockchain removes the need for a central authority. Cross-border payments, supply chain provenance, and interbank settlement are real examples where this matters.
The key qualifier: if all parties already trust one organization to run the database, you do not need blockchain. The technology is valuable specifically when that trust does not exist.
## 2. Digital ownership with programmable royalties
NFTs got a bad reputation from speculative trading, but the underlying concept of provable digital ownership with automated royalty distribution is powerful. We have built marketplaces where creators receive royalties on every secondary sale, enforced by smart contracts rather than honor systems.
This works because the alternative (tracking secondary sales manually and hoping buyers pay royalties) is operationally impossible at scale.
## 3. Credential verification
Academic credentials, professional certifications, and compliance attestations are expensive to verify because each verification requires contacting the issuing organization. An on-chain credential registry lets any party verify a credential instantly without calling the issuer.
This saves real money. Large employers spend thousands of dollars per hire on background verification. A blockchain-based registry reduces that to a near-zero-cost lookup.
## What does not work
Supply chain tracking where all participants are within one company. Voting systems where the threat model does not justify the complexity. Any use case where "put it on the blockchain" is the first idea rather than the last resort after evaluating simpler alternatives.
