🚨JUST IN: Vitalik Buterin unveils Ethereum's next era as a "cryptographic world computer." The Ethereum co-founder says the network is "really not just a blockchain anymore," but a system combining blockchains with modern cryptography to be cheaper, faster and more private. He says next year's Hegota upgrade is likely Ethereum's last "normal" one, with everything after focused on zero-knowledge proofs and quantum safety. By 2030, he expects transactions to finalize in as little as 8 seconds, down from around 200 seconds in 2015.
