Welcome to the Scroll developer documentation!
Scroll is its own Layer 2 network built on Ethereum (more specifically, a "zero-knowledge rollup").
If you're experienced in building on Ethereum, your code, dependencies, and tooling work with Scroll out of the box. This is possible because our network is compatible with EVM bytecode and designed to feel just like developing on Ethereum.
Scroll gains its security and speed by executing transactions off-chain and producing a cryptographic proof that the transactions were executed correctly. This cryptographic proof is verified in a smart contract on L1, ensuring that all code executed on Scroll L2 behaves just as if it were executed on Ethereum L1.Learn more about Scroll's architecture →

ZK Rollups allow for more activity on the network, minimizing congestion. By inheriting the security of Ethereum, which verifies the behavior of the network using zero-knowledge proofs, Scroll can process more transactions without compromising on decentralization.
On Ethereum, competition for blockspace results in higher costs per transaction, as each transaction makes a bid to be included in the next block. Scroll leverages recent breakthroughs in zero-knowledge proofs and hardware acceleration to vastly increase secure blockspace and minimize transaction costs for users.
After the merge, Ethereum blocks reliably confirm every 12 seconds. Scroll blocks are minted every 3 seconds, and for the sake of lower-risk operations, transactions can be assumed to be final once included in a block. This opens up new possibilities for on-chain interaction in social and gaming applications.
Scroll builds on Ethereum's vision. Our ethos is to build Ethereum, not to splinter it. Decentralization, permissionlessness, censorship-resistance, and community ownership are the core of what we do and the roadmap we're building. We believe in open-source software, and we work closely with the Ethereum Foundation's Privacy and Scaling Explorations team to support their work on a zkEVM that might someday be the heart of Ethereum.
We also work with governance DAOs and other open-source protocols to make sure that as applications are deployed, we're working to grow their impact - whether that be in public goods, core infrastructure, or the next generation of zero-knowledge use cases.
We know the challenges of building in the open and getting user engagement! Scroll has a blossoming community of users and builders, and with a Discord community of over 500,000 members eager to try out applications on our testnet or mainnet, we're excited to connect builders with users who can provide real-world feedback.
Our mainnet is now live, and we're diligently working to bring more integrations and support infrastructure to the network.
