Silvio Micali on Blockchain’s Core Significance and the Three Major Challenges Facing the Digital Economy

MIT professor, Turing Award winner, and cryptography expert Silvio Micali summarizes the core significance of blockchain in the global digital economy and the three major challenges it must overcome.

After two world wars, Europe created a tightly integrated market that fostered unprecedented peace and prosperity; a similar digital integration is now emerging worldwide, demanding better technology to address three critical challenges.

Security : Economic growth relies on law and courts, but in the global digital realm, reliance on punishment alone is insufficient; robust digital security is needed to prevent dishonest computational behavior and eliminate “security havens.”

Trust : While shared trust underpins massive critical transactions, finding common trustworthy parties on a global stage is difficult; technology must generate virtual trustworthy entities, with distributed ledger (blockchain) playing a central role, provided it remains truly decentralized and does not become a new concentration of power.

Balance : Society must balance collective and individual needs, such as privacy versus anti‑money‑laundering; tools like zero‑knowledge proofs and secure custodial systems are essential to achieve this equilibrium.

Micali believes current technology is sufficient to build a proud, universal digital economy, and that deeper collaboration between the United States and China can generate even greater benefits.

Ant Financial: Building the Infrastructure for Global Trust with Blockchain

Ant Financial leverages blockchain to create a trustworthy social infrastructure, supporting consistent and reliable data, assets, and contracts. Its public‑chain platform enables transparent charitable donations, while multi‑party consensus mechanisms ensure traceability for products such as Australian dairy and Chinese Maotai liquor. The company is also exploring blockchain applications in urban governance with Xiong’an New Area to build a “city of integrity.”
