👀Scroll is a native zkEVM (zero-knowledge Ethereum virtual machine) layer 2 solution for Ethereum, which aims to solve the scalability problem of Ethereum by providing a scalable, secure and efficient rollup solution. The following is a detailed introduction to the Scroll project:
1. Project Background and Positioning
Scroll was co-founded by Ye Zhang, Sandy Peng and Haichen Shen in 2021 and is a Chinese project.
As a layer 2 scaling solution for Ethereum, Scroll leverages zk-rollup technology to improve scalability and reduce transaction costs while maintaining security and decentralization.
The goal of Scroll is to create a zk-Rollup equivalent to Ethereum EVM, achieve maximum compatibility with EVM, and promote the vigorous development of the zkEVM ecosystem.
2. Technical features and advantages
Bytecode-level compatibility: Scroll is building a bytecode-compatible zkEVM to prove the validity of EVM calculations and the correctness of EVM execution in Layer 2. This means that developers can create smart contracts in any EVM-compatible language and deploy them to Scroll.
Efficiency: Scroll uses a new three-layer aggregation circuit prototype design, which can greatly improve the speed and efficiency of blockchain transactions.
Scalability: Scroll adopts a layered architecture design, which can be easily expanded to more application scenarios and user groups.
Decentralization: Scroll is committed to building a truly decentralized ecosystem that is not controlled by any centralized organization or individual.
Security: Scroll uses the highest level of encryption algorithms and verification technology to ensure the security of users' assets and information privacy.
3. Architecture and Working Principle
The Scroll architecture consists of three parts of infrastructure: Scroll nodes, Roller network, and Rollup and bridge contracts.
Scroll nodes are the main way applications and users interact with Scroll, responsible for building L2 blocks and submitting them to the Ethereum base layer (L1) through the Sequencer.
The Roller in the Roller network acts as a prover, responsible for generating proof of validity of the zkEVM to ensure that the transaction is executed correctly.
Rollup and bridge contracts ensure data availability for L2 transactions and allow users to transfer assets and information between L1 and L2.
How Scroll works includes:
Generate a series of L2 blocks through the Sequencer, and then hand over the block generation execution trace to the Coordinator.
The Coordinator randomly selects a Roller to generate a validity proof for each block track.
After generating a proof for a block, Roller sends it back to Coordinator. Every K blocks, the coordinator assigns an aggregation task to another prover to aggregate k block proofs into an aggregate proof A.
The Coordinator submits the aggregation proof A to the Rollup contract, verifies the aggregation proof by comparing it with the state root and transaction data commitment previously submitted to the Rollup contract, and finally determines the correctness of the L2 block.
IV. Development History and Financing
In 2022, the Scroll team will reach more than 40 people, of which more than 30 are ZK or blockchain researchers and developers.
In February 2023, Scroll officially launched the Alpha testnet open to all users, and stated that it will improve ZkEVM performance in the coming months.
In April 2023, Scroll completed a US$30 million Series A financing round, with investors including Polychian Capital.
On October 8, 2024, Binance announced that the 60th project Scroll (SCR) will be launched on Binance Launchpool. Users can invest BNB and FDUSD into the SCR reward pool on the Launchpool website after the specified time to obtain SCR. 👍
V. Market Response and Prospects
The Scroll project is very popular in the industry and has attracted the attention of many developers and investors.
By providing a scalable, secure and efficient rollup solution, Scroll is expected to solve Ethereum's scalability problem and promote the vigorous development of decentralized applications (dApps).
As the Ethereum ecosystem continues to develop and grow, Scroll, as Ethereum's layer 2 expansion solution, has broad market prospects and development space.
The Scroll project is a native zkEVM layer 2 solution for Ethereum, with technical advantages such as efficiency, scalability, decentralization and security. As the project continues to develop and improve, Scroll is expected to become an important force in the field of Ethereum expansion.
PS: There are too many L2 projects in the market, and ETH is performing poorly. Its performance after going online is expected to remain to be seen.
