According to Wu Blockchain, Ethereum co-founder Vitalik Buterin stated during his keynote speech at the 2026 Shanghai Blockchain Week that cryptographic technologies like FHE (Fully Homomorphic Encryption), obfuscation techniques, and iO, which were previously considered far from practical use, are advancing rapidly. Blockchain is evolving from primarily solving 'who can send what assets' to enabling programmable decisions on 'who can see what information.' Vitalik used FOCIL (EIP-7805) as an example: it proposes having 16 validators jointly provide transaction inclusion lists, reducing the ability of a single block builder to censor or delay transactions. He mentioned that in the next five years, more computations will be completed in parallel on user devices, mempools, and block-building stages. Ethereum will also continue to push for a significant reduction in finality time from the current ~16 minutes to 8-32 seconds. https://www.(wublock123.com)/news/vitalik-ethereum-finality-8-32-seconds-within-5-years-68855
