I’ve had this draft sitting around since Scroll went mainnet, but for some reason, I’ve procrastinated on it. Well, I’m finally done with it now.
Let's dive into Scroll. This article explores Scroll's ecosystem, it's architecture, breaking down its tri-layered framework and explaining how it facilitates seamless interaction between Ethereum and Scroll.
● Before I go into technicalities, here’s a short backstory on how scroll came to be:
In 2021, three individuals—Ye, Haichen, and Sandy—founded Scroll with a vision of creating an inclusive and scalable ecosystem for Ethereum. They recognized Ethereum's congestion issues during the DeFi boom in 2020 and sought to address scalability challenges.
Understanding Ethereum's trade-offs between security, decentralization, and transaction speed, they aimed to create a scaling solution similar to Ethereum but with improved efficiency, lower costs, and infinite scalability. Thus, Scroll was born.
● Scroll’s visions and values are:
• Vision:
· Create a decentralized computing platform accessible to all.
· Address challenges like high gas fees and network congestion.
· Empower humanity by making blockchains scalable, affordable, and secure.
· Preserve Ethereum’s core properties while advancing scalability.
• Values:
· Community-centric approach: Engage with the community and build in the open.
· Transparency and trust: Prioritize open-source development and collaboration.
· Decentralization and censorship resistance: Uphold Ethereum’s core properties and ensure security.
●Okay, Enough Story, What The H*ck Is Scroll?!
Scroll is a security-focused scaling solution for Ethereum, utilizing innovations in scaling design and zero knowledge proofs to create a new layer on Ethereum.
It aims to make Ethereum more accessible, responsive, and capable of supporting more users simultaneously.
Scroll uses cutting-edge research in zero knowledge proofs to build a Layer 2 rollup network on Ethereum, ensuring that all network activity is secured by smart contracts on Ethereum itself. This approach provides the network with high levels of security, decentralization, and censorship resistance.
Basically, Scroll is like a turbo boost for Ethereum, making it faster, cheaper, and able to handle more people at once. It uses fancy math to keep everything secure and private.
Scroll's mainnet is live on Ethereum, with ongoing efforts to further decentralize each component of the stack.
● Alright, scroll is a turbo boost for ethereum, but how does it work?!
•To understand how scroll works you need to understand the architecture...
· Scroll architecture consists of three main layers:
Settlement Layer: This layer manages data availability and ordering for no main Scroll chain. It verifies validity proofs and enables communication between Ethereum and Scroll, allowing users and applications to send messages and assets between the two networks. Ethereum serves as the Settlement Layer, hosting the bridge and rollup contract.
Sequencing Layer: Here, transactions submitted to the Scroll sequencer and those sent to the L1 bridge contract are executed by an Execution Node. This node generates L2 blocks. Additionally, a Rollup Node batches transactions, posts transaction data and block information to Ethereum for data availability, and submits validity proofs to Ethereum for finality.
Proving Layer: This layer includes a pool of provers responsible for generating zkEVM validity proofs to verify the correctness of L2 transactions. A coordinator assigns proving tasks to provers and relays the proofs to the Rollup Node for finalization on Ethereum.
In simple terms, the Settlement Layer handles communication and verification between Ethereum and Scroll, the Sequencing Layer processes transactions and generates blocks, and the Proving Layer ensures the validity of transactions using zero-knowledge proofs.
Basically, scroll works by bundling transactions together into rollups and generating a cryptographic proof of their validity. This proof is then verified by the Ethereum mainnet, which allows the transactions to be finalized.
● Getting Started With Scroll
• First things first, add scroll RPC to your wallet.
· RPC DETAILS
Network Name: ScrollMainnetR
PC URL: chainlist.org/chain/534352
ChainID: 534352
Symbol: ETH
Explorer: blockscout.scroll.io
• Bridging into Scroll
Visit: https://scroll.io/bridge
Connect wallet
Make sure the “From” is on ETH and “To” is on Scroll
Input the amount of ETH you’d like to bridge (Don’t forget to leave some ETH for gas fee)
Approve transaction
Bridge
If this is your first time bridging into Scroll, I’d suggest you use the official bridge following the guide above. Yes, there are other third-party bridges that you can use, but using the native bridge of a new protocol always has its perks.

● Funding
According to Crunchbase, Scroll has raised a total of $80.5M in funding over 4 rounds. Their latest funding was raised on Mar 6, 2023 from a Venture - Series Unknown round.
Scroll.io is funded by 20 investors. Qiming Venture Partners and Polychain are the most recent investors.
● Conclusion
In summary, Scroll is another layer 2 solution to Ethereum’s scalability challenges. By introducing innovative technology, Scroll addresses the bottleneck of high gas fees and network congestion, unlocking new possibilities for decentralized finance and beyond. With Scroll in place, Ethereum’s journey towards becoming a truly accessible and efficient decentralized platform takes a significant leap forward, offering users and developers a seamless and inclusive experience.
