Larry Fink, CEO of Blackrock, said at the WEF that the world must move faster toward digitized currencies built on a single unified blockchain to help reduce corruption. Coming from the leader of the world’s largest asset manager, the statement carried weight. BlackRock oversees more than 10 trillion dollars in assets, and when its CEO speaks about financial infrastructure, markets listen.

Fink outlined a future where nearly every financial asset lives on one shared system. Stocks, bonds, real estate, money market funds, and even cash would sit on a single blockchain ledger. For beginners, a blockchain is a shared digital record that many parties can verify at the same time. Once data is written, it is hard to change, which can improve trust and transparency.

One System for Every Asset

At the core of Fink’s vision is tokenization. Tokenization means turning ownership of an asset into a digital token on a blockchain. These tokens can represent full ownership or small pieces of an asset. That is where fractionalization comes in. Instead of buying an entire building or bond, investors could own a fraction, lowering the barrier to entry.

Programmable assets add another layer. Rules can be built directly into tokens, such as automatic dividend payments or compliance checks. Instant transfer means ownership can move in seconds, not days. Today, many stock trades still take up to two days to fully settle.

A real world example already exists. BlackRock’s tokenized money market fund, known as BUIDL, launched on a public blockchain in 2024. Within months, it attracted hundreds of millions of dollars in assets, showing that large institutions are willing to test this model when the benefits are clear.

Why Speed and Unity Matter

Fink’s call for a single, unified blockchain reflects a broader trend. Financial systems today are fragmented across countries, banks, and clearing houses. This complexity creates delays, higher costs, and opportunities for corruption. When records are scattered, it becomes easier to hide wrongdoing.

Recent data supports the shift. According to a 2024 report from Boston Consulting Group, tokenized real world assets could grow into a multi trillion dollar market by the end of the decade. Governments are also exploring central bank digital currencies, which are digital forms of national money, to improve payment efficiency and oversight.

Still, challenges remain. A single system raises questions about governance, privacy, and who sets the rules. Critics worry about concentration of power, while supporters argue that shared infrastructure can still support competition at the application level.
