1. Introduction
MegaETH is a Layer2 built within the Ethereum ecosystem, dedicated to breaking through the performance bottlenecks of Ethereum, aiming to achieve 100,000 TPS, block time of less than 0.01 seconds, and transaction fees of less than 0.01 U, providing users with an outstanding high-speed real-time experience. It is also one of the two Layer2 projects publicly invested in by Ethereum founder Vitalik.
2. What makes MegaETH special
2.1 Node specialization for high-speed operation.
Each node focuses on its own area for performance optimization through task division and independently set hardware requirements. Below are the task division and hardware requirements ranking for each node:
Sorter: Receives, sorts, and executes transactions.
Prover (OP): Validates transactions and generates proofs.
Replica Node: Receives transaction execution results and updates state replicas.
Full Node: Checks transactions to ensure state correctness.
Hardware requirement ranking: Sorter > Full Node > Replica Node > Prover
2.2 EigenDA components achieve efficiency, economy, and security.
EigenDA is the data availability layer used by MegaETH, providing high-throughput data storage (100,000 transactions per second). Taking OPBNB as an example, from a visual perspective, its transaction speed is equivalent to every 650 Uniswap transactions or 3,700 ERC-20 transfers. It is well-known that the ETH mainnet has high GAS costs. To solve this issue, EigenDA separates data storage from the mainnet, reducing redundant data transmission and storage costs. EigenDA utilizes Ethereum's robust security infrastructure to ensure that data can still be recovered even if some nodes become unavailable.
3. Current Progress
The testnet is set to launch in March 2025. MegaETH adheres to the principle of 'measure first, then build', clarifying that the current stage is for technical testing with no airdrop rewards.
