Blockchain Decoded: Unraveling its Mechanics and Strategic Utilisation
summary
Argues that blockchain is one type of distributed ledger and that many projects are merely replicated databases, not truly decentralized, so use cases must meet strict criteria from a published decision tree; recommends distributed ≠ decentralized and flags usability and replication costs, private‑key management failures, and regulatory friction as real blockers. Calls out remittances and a pan‑country healthcare shared ledger as sensible targets, notes frequent security breaches stem from bad integration not crypto, and estimates ~70% speculative projects that don’t need blockchain.
