Differences between centralized vs. decentralized internet. Benefits for privacy, security, and freedom; key challenges.

Context

In a centralized internet, a handful of large companies or organizations control the majority of online platforms and services. The flow of data and resources is managed through centralized servers, which are typically owned and operated by these entities. These servers act as hubs through which all traffic passes. Major social media networks like Facebook, Instagram, Twitter, and e-commerce platforms like Amazon are all examples of centralized platforms. The main characteristic of centralized systems is that all data, resources, and decisions are made by a few key players. These platforms aggregate large amounts of personal data from users, which they use for advertising, data analytics, and more. For instance, when you post something on Facebook or upload a photo to Instagram, your data is stored on Facebook’s servers, and the company decides how and when it will be used.

This data can be sold or used to target ads, raising concerns about privacy invasion and surveillance. Censorship: Centralized platforms often have the power to restrict or censor content. For example, governments or private companies can impose restrictions on what can be shared or seen, impacting freedom of expression. Single Points of Failure: Centralized networks are dependent on large data centres and servers. If these systems are attacked or go offline, entire platforms or services can be disrupted, causing widespread service outages.
