In the early days of blockchain, every transaction had to pass through a single main highway—the base layer of the network. As decentralized finance, NFTs, and global Web3 applications exploded in popularity, those highways quickly became crowded. Fees rose, transactions slowed, and the search for smarter solutions began. That search gave rise to one of the most exciting innovations in modern blockchain infrastructure: rollups and scaling technologies. Rollups and scaling tech are designed to dramatically increase blockchain capacity without sacrificing security or decentralization. By processing large bundles of transactions off the main chain and then posting verified summaries back to the base layer, rollups reduce congestion while preserving the trust guarantees that make blockchains powerful. Optimistic rollups, zero-knowledge rollups, and other advanced scaling approaches are now transforming how decentralized networks operate. On Blockchain Streets, this section explores the technologies that are helping blockchain grow from a niche experiment into global infrastructure. From transaction batching and cryptographic proofs to Layer-2 ecosystems and next-generation scaling frameworks, rollups represent a new chapter in blockchain performance. Welcome to the engines powering the future speed of Web3.
