I've always been curious about Bitcoin. Despite being such a highly decentralized system, it actually has some very fragile aspects.

As everyone knows, Bitcoin has no central authority. There are buyers and holders. People who send and receive, operate nodes, mine. And then there are those who build services and protocols on top. Everyone contributes in some way.

But here’s the important part. All of these activities are fundamentally based on software. Nothing functions without it. No one can buy, send, or run a node without software. Without software, Bitcoin itself doesn’t exist.

And software can’t be written on its own. Humans have to write it.

Initially, it was Satoshi Nakamoto. Then came Martti Malmi, Hal Finney, and over the years, many developers followed. It’s because of their work that Bitcoin exists today.

But honestly, the work of Bitcoin developers is largely unnoticed by most users around the world. It’s not well understood. Software development is a highly specialized field.

Bitcoin Core is the main implementation of the Bitcoin protocol. Understanding its core improvements, protocol evolution, and how developers approach these tasks is just as important as understanding Bitcoin itself.

In the latest issue of Bitcoin Magazine, the developers involved in core development speak about their work. What they’re building, and why it matters. By knowing this, you can see what Bitcoin truly is.

What has been needed to keep Bitcoin functioning for years, and what will be needed in the future. The answers lie in the ongoing efforts of these developers. Without their work, decentralized systems and the freedom they enable wouldn’t exist.
