The next big game changer for cryptocurrencies comes from artificial intelligence (AI).
That’s according to Consensys CEO and Ethereum co-founder Joseph Lubin. He told CoinDesk that autonomous or semi-autonomous agents can transact, coordinate and verify each other on decentralized networks, using crypto rails as the basis for machine-driven activity.
Lubin, who will speak at Consensus Miami 2026 next month, said he is “sympathetic to the idea that blockchain is for machine intelligence,” but does not see humans being displaced. Instead, increasingly intelligent interfaces will abstract complexity, allowing users to interact with cryptographic systems through intent rather than manual input. In that model, AI becomes the intermediary layer between people and protocols.
That vision carries risks. If AI infrastructure remains concentrated among large tech companies, “we could have problems,” Lubin warned. He argued that decentralized systems and cryptography will be essential to ensure accountability, allowing machines to “control each other” in transparent and verifiable environments.
Within that broader shift, products like MetaMask, a Consensys product, are evolving to reflect the change. Lubin said the wallet is being rebuilt as “a new type of neobank that you own and control,” part of a transition toward what he described as a “personal money operating system.” AI-powered agents could act on behalf of users, managing assets, executing transactions, and navigating a growing decentralized economy. “You can walk around with your personal financial system in your pocket,” he said.
The rise of corporate chains on Ethereum
Beyond the interfaces, Lubin pointed to structural changes throughout the Ethereum ecosystem. Blockchain architecture is also shaping how institutions approach adoption. Lubin expects “corporate chains” to become more common as companies seek greater performance and greater control over their infrastructure. Still, he argued that it is better to issue assets on Ethereum’s base layer, saying that “the best way to ensure that an asset is durable… is to mint it on Ethereum’s layer one,” even if the asset is later used on other networks.
Stablecoins, one of the fastest growing sectors of cryptocurrencies, are part of that transition, but not the end point. Lubin described them as a “springboard” toward more decentralized financial systems, noting that current models still rely heavily on centralized issuers. Over time, he hopes the growth of decentralized collateral will enable more robust crypto-native forms of money.
Regarding tokenization in general, Lubin suggested that traditional finance and decentralized finance are entering a period of convergence, combining centuries of financial innovation with newer blockchain-based systems. The result, he said, will be a more granular and programmable global economy.
Even as these changes accelerate, Lubin took a measured tone on long-term technical risks like quantum computing. While it’s not an immediate concern, he said Ethereum developers have been preparing for years.
“Many of us just see it as part of the natural evolution of Ethereum,” Lubin said.
