Exploring MEV Mitigation with Shutter’s Threshold Encryption

Discover how Shutter employs threshold encryption to combat Maximal Extractable Value (MEV), detailing its benefits and drawbacks.

Understanding MEV’s Impact on Users

Blockchains are known for their transparency, yet this can lead to value extraction through the manipulation of transaction order and inclusion, referred to as MEV (Maximal Extractable Value).

This issue predominantly affects networks like Ethereum, where data suggests that nearly $300,000 was lost in just one month due to sandwich attacks. Thus, MEV illustrates a significant hidden cost in transactions, particularly impacting larger trades during market volatility.

Shutter’s Approach to MEV

Various cryptographic solutions, including threshold encryption, have surfaced as methods to mitigate MEV. These methods encrypt transaction details before they enter the mempool, concealing them until transaction ordering is confirmed. Although promising, most implementations of encrypted mempools remain in the research phase.

Shutter has emerged as the pioneering threshold-encryption protocol crafted to address MEV challenges effectively. Operating on the Gnosis Chain mainnet, it stands out due to its practical deployment.

Mechanism of Threshold Encryption

The technique works by distributing decryption keys across a committee, ensuring that no individual can decode a transaction independently. This is achieved through a Distributed Key Generation (DKG) process, allowing users to securely encrypt their transactions and send them as ciphertext to the network.

Advantages and Future Prospects

One of the standout features of Shutter’s design is its flexibility; it functions across different blockchain consensus protocols without necessitating modifications. However, it is crucial to note that the committee is a permissioned structure requiring trust. The ongoing developments aim to transition toward a fully secure and less trust-dependent mempool framework.
