Blockstream CEO and cypherpunk pioneer Adam Back argued in a May 24 interview that VM-based smart contract platforms like Ethereum are fundamentally too complex to secure — and that complexity is now being weaponized. AI tools, he warned, are actively helping attackers systematically scan DeFi protocols for exploitable vulnerabilities at a scale and speed that defenders can't match.
Back reserved particular concern for restaking and rehypothecation mechanics, describing them as a form of privatized money printing that stacks leverage on leverage — creating systemic contagion risk that mirrors the worst excesses of traditional finance.
By contrast, Bitcoin's deliberately constrained design is the feature, not the limitation. Back's recommended strategy is straightforward: cold storage for self-custodians, or reputable spot ETFs for institutional exposure.
