As EVM developers, we live with the reality of sequential execution. One transaction happens after another. This is the EVM's biggest bottleneck. Let's explore how a new architecture, like the one proposed by MegaETH, changes this with a parallelized execution client.
The Standard EVM: A Single-Threaded World
A block is a linear sequence of transactions.
Each transaction modifies the state.
The next transaction can only be processed after the previous one is complete.
This is simple and secure but slow. It's like a single-core CPU from the 1990s.
The MegaETH Architecture: A Multi-Core, In-Memory Beast
MegaETH re-architects the execution client. Here's how it achieves massive speedups:
Parallel Execution: The Protocol's client is designed to identify transactions that don't depend on each other and execute them simultaneously across multiple CPU cores. For example, two users swapping different tokens on Uniswap can be processed in parallel.
Optimistic Execution: It can even execute transactions that might have dependencies and then quickly resolve any conflicts if they arise.
In-Memory Database: Instead of reading from slow disk storage for every state access, MegaETH keeps the entire state tree in RAM. This reduces I/O latency from milliseconds to nanoseconds.
What does this mean for your code? Nothing. Your Solidity smart contracts run as-is. The performance gains come entirely from the underlying Node infrastructure. Your dApp, which struggles at 50 TPS on a standard L2, could potentially handle 50,000 TPS on MegaETH without a single change to your code.
