Ever wondered how a blockchain can stay secure, stay decentralized, and still process thousands of transactions per second? The answer lies in layered solutions: layer-2 roll-ups, sharding on layer-1, and proofs that let nodes stay lightweight. Projects like Ethereum 2.0, Solana, and Polygon show the path forward. Keep an eye on how each layer trades off costs, and trust the math behind it.
