Shutter promotes base layer neutrality and information symmetry using threshold encryption. The protocol has 2 primary applications:

-Rolling Shutter prevents malicious MEV (front running, sandwich attacks) and censorship on L1s and Ethereum L2s by encrypting transactions as they are created and then decrypting them after the transaction order in the block has been fixed.

-Shielded Voting increases the fairness and integrity of votes on Snapshot and other voting platforms by encrypting all votes as they are cast and then decrypting them when the voting period has ended.
