Research Summary: Analyzing and Preventing Sandwich Attacks in Ethereum

[Chrisarch]

This is explicit in explaining the forward solution to Front-running @Ulysses

Miners have the edge in preventing this sandwich attacks if one can be able to bypass the mempool.

@Ulysses

But suppose you find a way to bypass the Mempool and go directly to the miners/validators? If you do this, no one on the network will see your transaction except the miners/validators.

However, as you pointed out, this process will result in a Private Transaction which @MiaZmy in his research summary illustrated its limitations.

Permit me to take an excerpt:

@MiaZmy

Although private transactions were proposed to protect end users from attacks, we find that only 18.1% of them were used for that purpose

Miners are also known to receive incentives from attackers and aid in permitting these attacks.

@MiaZmy

Attackers have already utilized private transactions to launch attacks; in these attacks, the attackers paid a large amount to the miner as a bribe to get their transactions executed. According to our evaluation, the miner earned as high as 700 ETH for mining a single private transaction.

Hence, one can say that Miners are at the centre in preventing some of these attacks.
