[Shutter Implements Encryption Technology to Address MEV Issues, Now Live on Gnosis Chain] Shutter reduces MEV issues in blockchain and protects transaction privacy through threshold encryption technology. Initially, the technology used encryption for each block cycle, but it has now been improved to encrypt transactions individually and is live on the RPC endpoint of Gnosis Chain. However, research has found that when cycle keys are reconstructed, transactions not included in blocks may also be exposed, revealing potential risks. (Cointelegraph)
