Blockchain scalability is a moving target. Classic layer‑1 solutions like sharding split the ledger, boosting throughput but adding complexity. Layer‑2 rollups bundle many transactions off‑chain, keeping base‑chain security but increasing data availability costs. Sidechains trade consensus speed for lower security, good for gaming and DeFi. Each approach balances speed, cost, decentralization differently—choosing the right mix depends on your use case.

Imagine a future where every patient’s health record is a tamper‑proof, self‑sovereign asset that only the patient can unlock. Blockchain enables secure, interoperable data sharing across hospitals, drug supply chains, and research labs, reducing fraud, speeding approvals, and giving patients true control. In the coming years, this could become the backbone of personalized medicine.
