The blockchain has been a key piece of the crypto boom of recent years, first popularized as a bank-less, secure, and cheap way to send money around the world. But the underlying technology that makes up blockchain has other potential applications, including digital journalism, music, advertising, and more.
Blockchain applications often require high-end computer CPUs, time, and electricity to validate data stored on the network. This can limit the number of users who can participate in a blockchain-based system. For example, blockchains that power cryptocurrencies require thousands of computers to mine and confirm transactions. This is why the crypto community has long debated how to make these systems scalable.
A new set of technologies is making blockchains more suited to business and government uses. For instance, a blockchain could be used to secure public data and replace centralized file systems. This could transform the public records request process, as it would be easier for journalists to get access to information and a much more secure way for governments to protect privacy and prevent bad actors from tampering with ballots in democratic elections.
Banks have also embraced blockchains, as they are a natural fit for their core function of moving money around the world. For example, some banks are offering tokenized funds that allow clients to buy shares in money market funds. Others are experimenting with blockchains to track the value of their assets. And the GENIUS Act stablecoin regulation passed in 2025 could lead to a reshaping of the US digital asset landscape by introducing new, bank-backed options.
