What is Linea? Understand zkEVM and the rising star of Ethereum Layer 2 in one article
In the ongoing race for Ethereum's expansion, Linea (LINEA) has quickly risen to prominence with its strong technological foundation and the background of the development team Consensys, which is affiliated with Meta (formerly Facebook). It is a Layer 2 ZK Rollup (zero-knowledge aggregation) chain driven by zkEVM, aiming to provide everyone with a faster, cheaper, and safer Ethereum experience.
1. Linea's core positioning: one of the scaling solutions for Ethereum
Ethereum itself has high security, but high transaction fees and slow processing speed remain long-term issues.
As Layer 2, Linea chooses to use:
ZK Rollup (zero-knowledge aggregation) technology
zkEVM (zero-knowledge proof technology executable as EVM equivalent)
Process a large number of transactions on Layer 2 and then submit them to the main chain to achieve:
Reduce Gas costs
Increase throughput
Maintain Ethereum-level security
2. Why is zkEVM important?
The challenge of traditional Rollups is that developers need to relearn languages or tools.
However, Linea's zkEVM is fully compatible with EVM, meaning:
The same syntax as smart contracts on Ethereum
Existing tools (MetaMask, Hardhat, Truffle) can be used directly
Developers can migrate existing DApps painlessly
This makes Linea's development costs extremely low, allowing for faster ecosystem expansion.
3. Linea's featured functions
Low cost, fast speed
Transaction fees are far lower than Ethereum's mainnet, suitable for high-frequency operations like DeFi, GameFi, and NFTs.
Consensys endorsement
Consensys is the developer of MetaMask, Infura, and Truffle, with a large developer resource pool.
This gives Linea a natural advantage of having a large number of tool integrations and global traffic.
Emphasize security and auditing
ZK technology itself has high security, and Linea has also undergone multiple security audits and testnet validations.
Complete developer support
Tools include:
SDK
APIs
Streamlined infrastructure
Teaching and development resources
Very friendly to Web3 startups.
4. The Linea ecosystem is rapidly growing
Many popular applications already exist on Linea:
DeFi: Balancer, Curve, Uniswap, SyncSwap
NFT & GameFi: Various blockchain games and collectible applications
Infrastructure: The Graph, Chainlink, Across, LayerZero
Whether it's TVL or daily active users, it's one of the rapidly growing Layer 2s.
5. Linea's vision: To enable true mass adoption of Ethereum
Linea aims to solve three major problems:
Ethereum is too expensive
Insufficient throughput
Web3 user experience is too complicated
Through ZK Rollup, low-cost transactions, strong developer support, and close integration with MetaMask and Infura, Linea hopes to become:
The Ethereum Layer 2 infrastructure most suitable for general users and large enterprises
Summary
Linea (LINEA) is a Layer 2 ZK Rollup chain based on zkEVM, featuring:
Low cost, high speed
Fully compatible with Ethereum
Consensys platform support
Ecosystem rapidly expanding
Suitable for DeFi, NFT, GameFi, and enterprise applications
Whether you are a trader, developer, or ordinary user, Linea is a next-generation Ethereum scaling solution worth paying attention to.
