The blockchain ecosystem is rising quickly, with new use circumstances and functions rising day by day. Nevertheless, the scalability and value problems with the Ethereum community pose important challenges to the adoption and innovation of DeFi improvement options and web3. That is the place layer-2 options come into play, providing quicker, cheaper, and safer transactions on prime of the Ethereum layer-1; and one such layer-2 answer is the Linea Community.

Linea Community is likely one of the most promising Layer-2 options. It’s a zkEVM layer-two chain launched by Consensys, the Web3 software program firm based by Ethereum co-founder Joseph Lubin. Linea leverages the ability of zero-knowledge proofs to validate transactions off-chain and submit a cryptographic proof to the Ethereum mainnet, attaining excessive throughput and low fuel charges.

Linea Community is suitable with the Ethereum Digital Machine (EVM), which implies that any sensible contract or decentralized utility (DApp) that runs on Ethereum may also run on Linea Community with none modification. The Community leverages a novel lattice-based prover that generates zkSNARK (Zero-Data Succinct Non-Interactive Arguments of Data) proofs effectively and securely, with out requiring a trusted setup.

Linea has a number of key options that make it stand out amongst different layer-2 options.

• Excessive transaction velocity: Linea can course of over 10,000 transactions per second, which is orders of magnitude quicker than Ethereum’s 15 transactions per second12.
• Low fuel charges: Linea reduces fuel charges by as much as 99%, making DeFi extra accessible and inexpensive for everyone12.
• EVM compatibility: Linea helps sensible contracts which are suitable with each zero-knowledge proofs and the Ethereum Digital Machine (EVM), enabling seamless migration and interoperability of current and new DApps12.
• Integration with MetaMask and over 100 DApps: Linea is built-in with MetaMask, the main web3 pockets with over 10 million month-to-month lively users12. Linea additionally hosts over 100 DApps, together with decentralized exchanges, lending protocols, perpetual contracts, and social finance platforms

Linea has proven spectacular development since its alpha mainnet launch in July 2023. As of this writing, its complete worth locked (TVL) is USD 52.32m. It has garnered over 100,000 weekly lively customers within the first month alone. This makes it the third largest ZK-rollup by TVL, simply behind zkSync Period and dYdX v3.

We have now established how Linea is a promising answer to scale Ethereum transactions. However how does Linea work underneath the hood? What are the parts that make up its structure and allow its options? Under are the primary components of Linea’s structure with their roles and features.

The Coordinator is the central part of Linea’s structure, performing as a hub of coordination for varied processes throughout the community. It manages the move of information between totally different parts, such because the Sequencer, the EVM State Supervisor, the Prover, and the Verifier. It additionally connects Linea to different blockchains, knowledge availability options, and community nodes. The Coordinator has a modular structure, the place every part operates in its personal setting and communicates with the others by way of the Coordinator. The Coordinator is chargeable for orchestrating the community and making certain its safety and effectivity.

The Sequencer acts because the core of Linea’s execution engine, ordering, establishing, and executing blocks. It takes transactions from Linea’s mempool and sequences them into a particular order. It then assembles these transactions into blocks and executes them utilizing linea-geth, an optimized model of the Geth protocol for zero-knowledge proofs. It additionally generates the hint knowledge from these executions, which is important for proof era. The Sequencer interacts with the Coordinator to optimize the blocks for proof era and knowledge availability, utilizing inner subsystems such because the Hint Generator and the Batch Conflator.

The EVM State Supervisor is a vital part of Linea’s community that makes use of the EVM (Ethereum Digital Machine) to run sensible contracts. It retains monitor of the worldwide state and the account state of the community and updates them primarily based on the execution hint knowledge from the blocks processed by the Sequencer. The Prover then makes use of this up to date state data to generate and submit zero-knowledge proofs to the Ethereum blockchain.

The Prover is the software program that creates zero-knowledge proofs for transactions on Linea. It makes use of the hint knowledge from the Coordinator and turns it right into a zero-knowledge succinct non-interactive argument of information (zk-SNARK). It employs a brand new lattice-based cryptography scheme that avoids a trusted setup and makes proofs faster than different zkSNARK methods. It additionally shrinks the proofs utilizing gnark, a library for quick zk-SNARK proof creation and verification.

The Verifier is the sensible contract that checks the proofs from the Prover. It’s on the Ethereum mainnet and connects Linea to Ethereum. It makes use of a public verification key to confirm the proofs and updates the state of Linea on Ethereum, which exhibits the most recent balances and knowledge of the customers and DApps on Linea. It additionally lets customers transfer funds between Linea and Ethereum.

The Community Knowledge is the part that makes Linea’s blockchain public and accessible. It solutions queries from customers and DApps utilizing the Ethereum JSON-RPC API requirements, together with account data requests from MetaMask customers on Linea. It additionally has a number of nodes for various features, equivalent to client-facing RPC-API nodes and archive nodes, with the assistance of Infura and Consensys. It adjusts to take care of community velocity and availability.

Linea rolled out the Linea DeFi Voyage, a six-week gamification expertise by way of which customers can discover the Linea ecosystem and study DeFi improvement providers in a enjoyable and rewarding method. Spanning from November seventh, 2023 to December 18th, 2023, this system aimed to cater to people in any respect ranges, from these new to web3 to skilled buyers, who can profit from the easy-to-follow guides and tutorial content material crafted in partnership with MetaMask Study and Intract.

The Linea DeFi Voyage consisted of ten waves of quests and core duties. Every wave featured a single core process, which was a compulsory quest that customers wanted to finish to advance to the following wave. Customers may additionally choose to finish bonus duties for extra rewards. Every process could have a distinct issue stage and XP reward. Customers may be part of the occasion at any time, however they wanted to finish all of the waves earlier than the top date to be eligible for the ultimate reward. The ultimate reward was the XP token, which is anticipated to be exchangeable for Linea ecosystem’s native token sooner or later
