The post Vitalik Buterin Redefines Crypto Security as User Intent Alignment appeared on BitcoinEthereumNews.com.

Vitalik Buterin shared on X a new framework that redefines security as intent alignment. Growing exploits show failures come from user misunderstanding, not cryptography. Redundant checks, simulations, and AI-assisted tools will shape future Ethereum security. Vitalik Buterin has published a groundbreaking security framework on X on February 22, 2026. He redefines security as actively closing the gap between users’ true intentions and the system’s actual behavior in crypto systems. Recent exploits prove most massive losses occur when users sign harmful transactions they misunderstand, not when cryptography fails. Why “Perfect Security” In Crypto Is Impossible According to Buterin, perfect security cannot exist. He explains this by showing that “user intent” is too complex to be fully defined or encoded. He illustrates this with the simple action of sending 1 Ethereum (ETH) to Bob, explaining that Bob is “a complicated meatspace entity that cannot be easily mathematically defined,” so representing him with a public key always risks sending funds to the wrong or compromised address.  As user goals grow more complex, the problem worsens. He cites privacy as an example, noting that encrypting messages alone is insufficient because metadata and timing patterns can still leak sensitive information. According to Chainalysis, the DPRK’s $1.5 billion hack of ByBit, the largest single hack in crypto history, accounts for the majority of service losses. By the end of June 2025, 17% more value had been stolen year-to-date (YTD) than in 2022, previously the worst year on record. Vitalik’s analysis shows why intent misalignment creates such catastrophic tail risks in practice, emphasizing that no amount of perfect code can overcome the inherent fuzziness of human goals. What Are the Recommendations? According to Buterin, a strong system’s security relies on its redundancy rather than perfection.   “Anything that the user can input into the system is fundamentally far…
