Learn what Layer 2 solutions are, the main types (rollups, state channels, sidechains), top projects, performance metrics, and how to start using them.
Rollups – Scaling the Blockchain
When working with Rollups, a Layer‑2 scaling technique that bundles many transactions into a single proof. Also known as idiomatic rollups, they help blockchains process more moves without slowing down.
Rollups sit on top of Ethereum, the leading smart‑contract platform that struggles with high demand. They are a type of Layer 2, an off‑chain layer that still relies on the base chain for security. Within rollups, there are two main families: Optimistic Rollup, which assumes transactions are valid unless challenged and Zero‑knowledge Rollup, which posts a cryptographic proof that every transaction is correct. Rollups encompass both families, require smart contracts on the base chain, and enable faster, cheaper trades.
Because rollups inherit security from their host chain, they influence how developers design dApps, how users pay fees, and how exchanges list tokens. If you’re curious about how these solutions affect market moves, token economics, or future upgrades, the posts below break down real‑world use cases, risk factors, and step‑by‑step guides. Dive in to see practical examples and stay ahead of the scaling curve.
