Suave
Suave refers to a complex and innovative approach aimed at addressing the challenges of Miner Extractable Value (MEV) in blockchain systems. MEV represents the profit that miners or validators can make through actions like reordering, censoring, or including specific transactions in a blockchain. This capability, while profitable for miners, introduces problems like reduced security, fairness, and decentralization in blockchain networks.
The primary issue at the heart of MEV is the need to establish an order for transactions within a block. This process is prone to manipulation, where miners may reorder or censor transactions for profit, leading to concerns about fairness and centralization. Sophisticated actors in the system, such as hedge funds or proprietary trading firms, can exploit these opportunities for arbitrage, further exacerbating the issue.
Flashbots, a research and development organization, emerged to tackle the negative impacts of MEV on smart-contract blockchains. They developed 'MEV Boost', a piece of open-source software facilitating a system called Proposer-Builder Separation (PBS). In this system, block builders submit blocks to relays, which are trusted entities that determine the most profitable block to be included on the blockchain. These relays act as intermediaries, ensuring the validity and privacy of the transactions.
The process involves several layers: users express their intent through transactions, which are then observed and bundled by searchers. Builders create blocks full of these transactions, while relays aggregate them and decide the most profitable ones for validators to sign. This chain of block production incorporates various levels of censorship resistance.
Suave, standing for Single Unifying Action for Value Expression, represents a new approach in this ecosystem. It focuses on creating a more decentralized, fair, and privacy-preserving environment for handling MEV. Suave introduces the concept of a decentralized auction system, where rules governing transaction bundling and block building are encoded in smart contracts. This system aims to minimize MEV impacts for users while maximizing profits for validators in a balanced way.
The Suave platform leverages technologies like Layer 2 blockchain solutions, trusted hardware enclaves, and a specialized Ethereum Virtual Machine (EVM) adapted for MEV-specific applications. The goal is to provide a set of tools and a platform for developers to create financial applications that offer privacy and decentralization. These applications run in the MEV time window, between block creations, and are designed to be resistant to common MEV strategies like front-running and sandwich attacks.
In summary, Suave represents a significant stride in tackling the challenges posed by MEV. It offers a platform and set of tools for building decentralized, privacy-preserving applications that can operate efficiently in the MEV landscape, aiming to bring fairness and balance to the process of block creation and transaction ordering in blockchain networks.
