Blockchain: Beyond Cryptocurrency and Toward Web3

Blockchain technology first emerged as the underlying infrastructure that powered Bitcoin – the original cryptocurrency. However, blockchain has evolved to enable much more than just digital currencies. Let’s explore some of the key ways that blockchain is moving beyond cryptocurrency and shaping the future of the internet as we know it.

Decentralization Through Blockchain

One of the core value propositions of blockchain technology is decentralization. Rather than having data controlled and stored by a single centralized entity, blockchain allows data to be distributed across a network of computers.

Greater Transparency and Immutability

This decentralization provides greater transparency, as all transactions on a blockchain are viewable to participants in the network. Additionally, the cryptographic foundations of blockchain make transactions virtually immutable once recorded on the ledger.

Shifting Power Dynamics

By reducing reliance on central intermediaries, blockchain has the potential to shift power dynamics in industries like finance, supply chain management, voting, real estate, and more. This could reduce costs and overhead while giving users greater control.

Beyond Finance: Impacts Across Industries

While blockchain made its debut with Bitcoin in the realm of finance, the technology is now poised to transform many other industries as well.

Supply Chain Management

Blockchain’s transparency, traceability and immutability make it ideal for enhancing supply chain management. Walmart and other major retailers are already experimenting with blockchain-based systems to track foods and other products from farm to shelf.


Secure record keeping and sharing is vital within healthcare. Blockchain solutions could give patients control over their medical records and help providers access information securely.

Government and Voting

Several governments have piloted blockchain-based mobile voting platforms. Such systems could encourage participation while reducing fraud. Estonia has already implemented blockchain technology within some governmental processes.

Web3: Blockchain as the Foundation for a New Internet

Beyond transforming specific industries, blockchain is also viewed as a seminal technology for Web3 – the next phase of the internet.

What is Web3?

Web3 represents a new model of internet interaction and operation that incorporates principles of decentralization through blockchain, peer-to-peer networks, and token-based economics.

Contrast With Web 2.0

This contrasts with the Web 2.0 model that dominates today’s internet, where power and control still tend to consolidate into the hands of big tech giants. Web3 aims to put more control into the hands of users.

User Data Rights

For example, users could have more ownership over the data they generate, rather than this data being controlled and monetized by centralized platforms like Google and Facebook.

Implementing Web3 Principles

New blockchain-based apps are already emerging that embody Web3 ideals. These involve concepts like decentralized cloud storage, decentralized digital identity frameworks, decentralized finance, and more.
