Overview

Execution - Decoupled SVM

The SOON SVM is more than just an SVM fork. Instead, SOON leverages the Decoupled SVM for its execution layer. Rather than merely forking the Solana client and tweaking several parameters, we are further modularising the SVM to build a rollup-up specialized SVM which provides greater network security, reduced DA wastage and unlocks further performance improvements.

Data Availability - Celestia / EigenDA / Avail

Data availability (DA) is a critical component of SOON's architecture, ensuring that all transaction data is accessible and verifiable by all participants in the network. SOON allows the DA layer to be configurable, giving operators the option to choose between Celestia, EigenDA, and Avail. This configurability enables the SOON Chain operator to select the most cost-effective and efficient DA solution based on their specific needs. Celestia, for instance, offers innovative Data Availability Sampling (DAS) techniques that allow nodes to verify data availability without downloading the entire dataset, enhancing scalability and security. EigenDA and Avail also provide robust data availability solutions that can be tailored to different use cases, ensuring that SOON can meet the diverse requirements of various applications and ecosystems.

Settlement - Bitcoin EVM/Ethereum/Cosmos

SOON Mainnet can utilize any base layer as its settlement layer, starting with EVM-compatible layers like Ethereum. This provides established economic security and liquidity. The settlement layer ensures transaction security and finality, leveraging robust infrastructures and extensive validator networks. SOON’s flexibility allows future integration with other layers such as Bitcoin and Cosmos.

Proving Mechanism - OP Stack

SOON uses the OP Stack. This approach leverages the economic security of the underlying L1 while benefiting from the high throughput capabilities of the SVM. The OP Stack includes a decentralized fault proof mechanism, enabling any user to challenge the state of the SOON Layer 2 by submitting a fault proof on the L1. Initially, SOON will use interactive Fraud Proofs as part of its Optimistic Rollup mechanism. However, there are plans to transition to Zero-Knowledge (zk) proofs in the future, which will enhance security and reduce the need for interaction in the fault proving process, further shortening the challenge periods and improving user experience.
