A few days ago, the white paper of edgeX was released. I have been reading it for the past two days and will give you a brief analysis The first thing to confirm is that edgeX will be an App Specific Rollup, a vertical application chain focused on high-frequency trading, inheriting ETH security and finality And this white paper mainly discusses the three core pillars of the technology stack 1. Modular multi virtual machine architecture - edgeVM+edgeEVM+Future VM Actor This friend who is familiar with Hyperliquid should not be unfamiliar with it. VM is specifically used for PerpDex trading, while EVM is used to run Defi's universal solution, forming a synergistic effect with Perp As for why we need to create a separate VM, it must be designed for the execution environment of high-frequency financial tasks such as Perp, which is very different from the general EVM. For example, the significant overhead inherent in the EVM architecture, such as instruction decoding and complex metering, is eliminated, and transaction logic is compiled into efficient WASM for fast execution. The allocation mechanism of CPU and memory also ensures the priority of transaction resources, without causing conflicts and congestion with other traffic in the general EVM As @ kiki520_ eth mentioned before - 'Perp has a traffic entry point, so it's better to do Defi Universal Chain by itself, without playing with the existing cryptocurrency circle.' This is also a trend in this round, where top applications have greater say and even completely establish their own portals, and the bargaining power or premium power of the chain itself is decreasing. The theory of fat protocol and thin application can be said to be a turning point in 2025, and it will develop towards the direction of Web2 fat application in the future In the future, there may be new product lines such as options exchanges, predictive markets, or experimental return strategies that can be directly plugged into existing EDGE stacks through a form similar to hot swapping, without the need for overall upgrades or network forks, and without affecting the security and integrity of the core perpetual trading engine. This is the VM Actor mechanism of Future, which is still quite powerful 2. Deterministic Parallel Trading Execution - PTE Friends who are familiar with the difference between Solana's parallel mechanism and Aptos Block STM's parallel mechanism should be familiar with it. One is deterministic parallelism based on Access Lists, similar to 'priors'. One approach is to assume optimistically that there are no conflicts, and then roll back and execute serially again in case of any conflicts, similar to a 'a posteriori' If it is a universal L1/L2, there is not much superiority or inferiority between the two. However, for edge, an App Specific Rollup, optimistic parallelism can introduce unpredictable delay peaks and wasted computing cycles during periods of high market volatility. Therefore, stability, or determinacy, is more important than "peak TPS". Therefore, edge chooses Deterministic PTE (Deterministic Parallel) In the EDGE Stack, BTC-USDT transactions and ETH-USDT transactions are processed in parallel by completely independent VM Actors without interfering with each other. This also means that the TPS of the entire VM can grow linearly with the increase of popular assets, completely breaking the single threaded bottleneck and achieving high performance while maintaining stability 3. FastLane - Fast Lane If we set aside some of the mechanisms of MEV, the vast majority of L1 or L2 nodes/sequencers follow a FIFO (first in, first out) rhythm, which is not very effective for a high-performance Perp. For example, at a certain time point, a key market maker's quote is forced to be placed behind a pile of complex governance voting messages, which has a significant impact. EDGE Stack has designed an entrance controller to perform semantic detection on the incoming TX and distribute traffic to different processing channels based on operational urgency and resource requirements The fast lane is related to placing orders, whether it's Limit Order, Market Order, cancellation/modification of orders, etc. TX has priority and enjoys preemptive scheduling privileges, including sub second soft confirmation, which is basically the CEX experience Slow lane is related to asynchronous settlement, such as asset deposit and withdrawal, margin adjustment, governance, staking, contract interaction with edgeEVM, etc., and regular on chain operation experience The last sentence to summarize the technical architecture described in the white paper is that Monad and MegaETH are designed to make all Ethereum applications run faster; The EDGE Stack is designed to ensure the most stable, fast, and fair trading of high-frequency derivatives
