Chris Dixon, February 2018
During the first era of the internet — from the 1980s through the early 2000s — internet services were built on open protocols that were controlled by the internet community. This meant that people or organizations could grow their internet presence knowing the rules of the game wouldn’t change later on. Huge web properties were started during this era including Yahoo, Google, Amazon, Facebook, LinkedIn, and YouTube. In the process, the importance of centralized platforms like AOL greatly diminished.
During the second era of the internet, from the mid 2000s to the present, for-profit tech companies — most notably Google, Apple, Facebook, and Amazon (GAFA) — built software and services that rapidly outpaced the capabilities of open protocols. The explosive growth of smartphones accelerated this trend as mobile apps became the majority of internet use. Eventually users migrated from open services to these more sophisticated, centralized services. Even when users still accessed open protocols like the web, they would typically do so mediated by GAFA software and services.
The good news is that billions of people got access to amazing technologies, many of which were free to use. The bad news is that it became much harder for startups, creators, and other groups to grow their internet presence without worrying about centralized platforms changing the rules on them, taking away their audiences and profits. This in turn stifled innovation, making the internet less interesting and dynamic. Centralization has also created broader societal tensions, which we see in the debates over subjects like fake news, state sponsored bots, “no platforming” of users, EU privacy laws, and algorithmic biases. These debates will only intensify in the coming years.
One response to this centralization is to impose government regulation on large internet companies. This response assumes that the internet is similar to past communication networks like the phone, radio, and TV networks. But the hardware-based networks of the past are fundamentally different than the internet, a software-based network. Once hardware-based networks are built, they are nearly impossible to rearchitect. Software-based networks can be rearchitected through entrepreneurial innovation and market forces.
The internet is the ultimate software-based network, consisting of a relatively simple core layer connecting billions of fully programmable computers at the edge. Software is simply the encoding of human thought, and as such has an almost unbounded design space. Computers connected to the internet are, by and large, free to run whatever software their owners choose. Whatever can be dreamt up, with the right set of incentives, can quickly propagate across the internet. Internet architecture is where technical creativity and incentive design intersect.
The internet is still early in its evolution: the core internet services will likely be almost entirely rearchitected in the coming decades. This will be enabled by crypto-economic networks, a generalization of the ideas first introduced in Bitcoin and further developed in Ethereum. Cryptonetworks combine the best features of the first two internet eras: community-governed, decentralized networks with capabilities that will eventually exceed those of the most advanced centralized services.
Decentralization is a commonly misunderstood concept. For example, it is sometimes said that the reason cryptonetwork advocates favor decentralization is to resist government censorship, or because of libertarian political views. These are not the main reasons decentralization is important.
Let’s look at the problems with centralized platforms. Centralized platforms follow a predictable life cycle. When they start out, they do everything they can to recruit users and 3rd-party complements like developers, businesses, and media organizations. They do this to make their services more valuable, as platforms (by definition) are systems with multi-sided network effects. As platforms move up the adoption S-curve, their power over users and 3rd parties steadily grows.
