If the vision of Larry Fink — CEO of BlackRock , the world’s biggest money manager — becomes reality, all assets from stocks to bonds to real estate and more would be tradable online, on a blockchain.

“Every asset — can be tokenized,” Fink wrote in his recent annual letter to investors.

Unlike traditional paper certificates signifying financial ownership, tokens live securely on a blockchain, enabling instant buying, selling, and transfers without paperwork or waiting — “much like a digital deed,” he wrote.
