The Solana Foundation recently announced their plan to remove stake from their delegation program if participating validators produce blocks including sandwich attacks.
Here is a useful thread for extra context, also you can view the announcement on the foundation’s Discord.
- a) You are aware of Jito's modified Solana client to improve the efficiency of MEV extraction. Describe how unaligned validators can run their own private mempool to facilitate sandwich attacks.
- b) Identify the validators that had their stake removed, and determine the total amount removed.
- c) Write code that, given a Solana block, outputs whether a sandwich attack was included.
