If you’ve ever struggled to explain cryptocurrency to a family member or friend, this guide will be your go-to resource for breaking down what bitcoin is and why it matters. Bitcoin is more than just digital money — it represents a fundamental shift in how we think about and use currency worldwide. Let’s explore bitcoin, the technology behind it, and why it’s poised to transform the future of money and the internet.
This explanation is inspired by insights from Peter van Valkenburgh, Director of Research at Coin Center, and Brian Brooks, former Acting Comptroller of the Currency, who together offer a crystal-clear picture of bitcoin’s role in the evolution of digital infrastructure.

What Is Bitcoin?
Simply put, bitcoin is the world’s first cryptocurrency, powered by the world’s first public blockchain network. But what does that mean exactly?
Bitcoin allows you to send and receive value anywhere in the world using only a computer and an internet connection. Unlike traditional digital payment methods, bitcoin operates without the need for a trusted middleman like a bank or payment processor.
This lack of intermediaries makes bitcoin the world’s first public digital payments infrastructure. By “public,” we mean that it’s accessible to everyone and isn’t owned or controlled by any single corporation or government.
Think about it — we have public infrastructure for information, like the internet, email, and websites. But when it comes to payments, the only truly public system has been cash, which only works in person. Before bitcoin, sending money remotely meant relying on private banks and their ledgers, which are limited by geography, cooperation between banks, and fees.
With bitcoin, the ledger is the public blockchain. Anyone can add entries to this ledger by transferring bitcoins to someone else. You don’t need to prove your nationality, creditworthiness, or identity — you just create a bitcoin address at no cost and start receiving payments digitally.
Bitcoin Is Not Perfect — Yet
Just like email wasn’t perfect when it was invented in 1972, bitcoin isn’t flawless today. It’s not accepted everywhere, isn’t often used to quote prices, and its value can be volatile. But the fact that it works without trusted intermediaries is a groundbreaking computer science achievement.
Bitcoin’s significance extends beyond finance — it represents a new era of freedom, prosperity, and human flourishing, comparable to the birth of the internet itself.
Why Build More Public Infrastructure?
If bitcoin can replace private payments infrastructure, what else could it transform? The idea is to replace other private choke points that limit human interaction and innovation.
Why should we prefer public blockchain infrastructure over corporate intermediaries? Because the current critical infrastructure is increasingly controlled by fewer, larger companies, and their failures are becoming more severe and widespread.
Consider these examples:
- Nearly half of all Americans (143 million people) had their Social Security numbers exposed in the Equifax data breach.
- The SWIFT network, which banks use for international money transfers, has been exploited in multiple hacks, including the largest electronic bank robbery in history — $1.8 billion stolen from Punjab National Bank.
- In 2016, a massive botnet attack took down major news websites like CNN, Fox News, and The New York Times for hours.
- Internet of Things (IoT) devices like pacemakers, baby monitors, and even Jeep vehicles have been hacked, putting lives at risk.
These vulnerabilities stem from systems with single points of failure — whether a corporation or a government. Just like the internet removed single points of failure in communications by creating a decentralized network, blockchains aim to do the same for payments and IoT infrastructure.
The Evolution of the Internet: Web 1, Web 2, and Web 3
Brian Brooks, former Acting Comptroller of the Currency, breaks down the evolution of the internet and how cryptocurrency fits into the next phase, Web 3.
Web 1: The Curated Internet
Early internet users might remember AOL accounts, where you could only view content curated inside a “walled garden.” It was mostly read-only content, like looking at articles in a magazine — you couldn’t interact or contribute.
Web 2: The Interactive Internet
Web 2 changed everything by letting people not only read but also write content. Blogs, social media, and user-generated content exploded. However, this era also centralized power in a handful of corporations like Facebook, Google, and Twitter, who monetized this activity.
Web 3: Decentralization and Ownership
Web 3 is about owning the actual networks that power the internet. Crypto assets represent ownership stakes in decentralized networks, unlike in Web 1 and 2 where companies like Google controlled the infrastructure.
For example, owning Ethereum tokens means you own part of the Ethereum network, unlike owning stock in Google, which owns the traditional internet infrastructure.
How Digital Assets Fit Into Web 3
Digital assets, like Bitcoin or Ethereum tokens, serve as keys to participate in and maintain decentralized ledgers. Miners or validators who help keep these networks running are rewarded with tokens, giving them an ownership stake.
Applications built on these networks depend on their underlying infrastructure, similar to how apps on your phone depend on the operating system. Investors choose which networks to support, and token holders get to vote on the network’s future — a level of democratic control absent from centralized Web 2 platforms.
In essence, decentralized networks put control into the hands of users and investors rather than a small group of corporations, paving the way for a more open and equitable internet.
Why This Matters for America and the World
To ensure these innovations flourish, especially in the United States, we need policies that encourage innovation while maintaining security. The promise of blockchain technology is to create resilient, decentralized infrastructure that can’t be easily compromised or controlled by a few players.
Bitcoin and blockchain are the foundation of this new public infrastructure, offering hope for a future where critical systems are more secure, accessible, and fair.
Whether you’re new to cryptocurrency or a seasoned enthusiast, understanding these fundamentals helps you appreciate why bitcoin is much more than just a digital asset — it’s a revolutionary step toward a decentralized future.
