Ethereum founder Vitalik Buterin (비탈릭 부테린) has pointed to Chinese AI model DeepSeek V4 as a key technology for strengthening privacy on Ethereum. He said security and privacy are hard to guarantee under centralised AI structures as AI increasingly handles crypto wallets and blockchain interactions. Buterin described combining local AI models with an Ethereum access layer and zero-knowledge proofs to reduce exposure of metadata, IP addresses and wallet balances.

Polygon has launched a Private Mempool designed to protect transactions from frontrunning and sandwich attacks. Developers can integrate it by changing a single RPC URL. Polygon said transactions bypass the public mempool and are delivered directly to block producers managed by a validator set, preventing arbitrary manipulation of transaction ordering. It added the structure addresses malicious MEV issues common in applications such as Polymarket while maintaining decentralisation.
