Beyond Bitcoin: Blockchain Is Finding Its Place in Finance
Wall Street investment products, blockchain infrastructure, and AI-powered payments are revealing a broader role for cryptocurrency technology.
When most people hear the word cryptocurrency, they think of Bitcoin, changing prices, or buying and selling digital coins.
But cryptocurrency is only one part of the bigger picture.
Blockchain is the technology that makes cryptocurrencies possible. It maintains a shared digital record of transactions, allowing participants to verify information without relying on a single organization to maintain the record.
But blockchain can record more than cryptocurrency transactions. It can also store or reference information about assets, ownership, agreements, and other activities. Once information is recorded, the system is designed to make unauthorized changes difficult to hide.
Financial institutions are exploring blockchain as a way to manage assets, connect financial systems, and automate transactions.
At Chainlink's LINK NYC event on October 29, several financial industry executives discussed these developments in three conversations featured on the Milk Road Crypto podcast.
The participants included Teddy Fusaro, president of Bitwise; John D'Agostino, head of institutional strategy at Coinbase; Andrew McCormick, head of institutional and market development at Chainlink Labs; and Joseph Chalom, CEO of SharpLink.
Their discussions highlight three areas where progress is already visible.
1. Wall Street Is Moving Beyond Bitcoin Investing
In January 2024, the U.S. Securities and Exchange Commission approved the listing and trading of spot Bitcoin exchange-traded products.
These investment products made it possible for people to gain exposure to Bitcoin through traditional brokerage accounts without directly managing a cryptocurrency wallet.
That was an important development for cryptocurrency investing.
But financial institutions are also exploring how blockchain technology can be used for something different: operating financial systems.
One example is tokenization.
Tokenization involves creating a digital representation of an asset or financial entitlement on a blockchain. Depending on its structure, that representation might relate to a security, a fund, or another financial asset.
The Depository Trust & Clearing Corporation (DTCC), a major provider of U.S. financial market infrastructure, has been developing services involving tokenized securities and collateral management.
Its work includes testing ways to move eligible financial assets between traditional systems and blockchain-based environments.
The Benefit
Blockchain could help financial institutions manage and transfer assets more efficiently while maintaining verifiable records of transactions.
Instead of being used only to hold cryptocurrency, blockchain is being developed as technology that can support financial operations.
2. Chainlink Is Helping Connect Traditional Finance and Blockchain
One challenge facing financial institutions is that their existing systems were not originally designed to communicate with blockchain networks.
Banks, investment firms, custodians, and decentralized applications often operate using different technologies and procedures.
Chainlink develops infrastructure intended to help connect those systems, including tools for coordinating information and activities across traditional applications and blockchain networks.
One example is Chainlink CustodySync, introduced in October 2026 with Anchorage Digital as its launch partner.
To understand why this matters, consider how institutional cryptocurrency custody works.
A financial institution may hold digital assets with a qualified custodian, which is responsible for safeguarding those assets.
However, using those assets in decentralized finance (DeFi) applications can involve additional technology, operational requirements, and risks.
CustodySync is designed to allow institutions to access certain DeFi applications through digital representations of their assets while the underlying cryptocurrency remains with the custodian.
The Benefit
Financial institutions can explore additional uses for their digital assets without necessarily transferring the underlying assets out of qualified custody.
This approach could make it easier to connect traditional financial services with blockchain applications while preserving existing custody arrangements. It does not eliminate the risks associated with DeFi.
3. AI and Blockchain Are Beginning to Intersect
The third conversation explored another development: artificial intelligence and automated financial transactions.
An AI agent is software designed to carry out tasks on behalf of a person or organization, within the permissions and controls it has been given.
Some of the technology needed for AI-assisted payments is already being developed and tested.
For example, Coinbase introduced x402, a payment protocol that allows compatible applications and AI agents to make payments using digital assets, including stablecoins.
A stablecoin is a cryptocurrency designed to maintain a relatively stable value, commonly by referencing a currency such as the U.S. dollar.
In a supported application, software can request a paid service and complete a payment through the protocol.
The Benefit
AI agents could automate certain financial transactions, reducing the need for people to manually approve and complete every individual step.
Blockchain-based payment systems offer one way for these applications to transfer value digitally, including between software services.
These capabilities are still developing, and appropriate security controls and transaction permissions remain essential.
What Does This Mean for Everyday People?
You don't need to own cryptocurrency to understand why these developments matter.
Here's what is happening across the financial industry:
- Traditional finance: Institutions are developing ways to represent and manage assets using blockchain technology.
- Blockchain infrastructure: Companies are building connections between existing financial systems and decentralized applications.
- Financial automation: Developers and payment companies are testing ways for authorized software to carry out transactions.
These developments do not mean blockchain will replace banks, that all assets will become tokenized, or that AI will manage everyone's money.
They do show that cryptocurrency-related technology is being developed for uses beyond trading digital coins.
The Bigger Picture
Bitcoin helped introduce blockchain technology to a much wider audience.
Today, some of the industry's work is focused on what can be built with that technology.
As these developments continue, blockchain's broader capabilities are becoming easier to recognize. What began as the technology behind Bitcoin is finding practical applications across the financial industry.
