According to Foresight News, Vitalik Buterin addressed attendees at the EthCC conference, emphasizing a pivotal change in blockchain development strategies. Buterin noted that the approach of 'space growth' may no longer be the most effective strategy. He advocated for a transition from merely utilizing blockchain, zero-knowledge proofs (ZK), and fully homomorphic encryption (FHE) to constructing systems that achieve specific attributes. He stressed that the key focus should be on solving complex problems efficiently rather than simply becoming smarter in tackling trivial issues.
