# Why you should care about privacy and decentralization
Privacy is a fundamental human right that allows us to express ourselves freely, without fear of being tracked, monitored, or censored by anyone. However, most of the popular chat and social media apps we use today are not very privacy-friendly. They often require us to provide personal information such as phone numbers or email addresses to create an account, and they collect and store a lot of metadata about our communications, such as who we talk to, when, where, and for how long. This metadata can reveal a lot about our personal lives, preferences, habits, and relationships, and it can be accessed by third parties such as advertisers, governments, hackers, or malicious actors.
Decentralization is a way of designing systems that do not rely on a single point of control or failure. Instead of having a central server that handles all the data and communication, decentralization distributes the tasks among multiple nodes that cooperate with each other. This makes the system more resilient, secure, and scalable, as well as more respectful of users' autonomy and sovereignty. Decentralized systems are harder to censor, manipulate, or shut down by anyone.
# How decentralized chat and social media apps work
Decentralized chat and social media apps are applications that use peer-to-peer (P2P) or blockchain technologies to enable users to communicate directly with each other, without intermediaries or servers. They use encryption to protect the content and metadata of the messages from eavesdropping or tampering, and they use various methods to discover and connect with other users on the network. Some of these methods include:
- Distributed hash tables (DHTs), which are data structures that store key-value pairs across multiple nodes on the network. DHTs can be used to store user profiles, contact lists, public keys, or message pointers.
- Onion routing, which is a technique that routes messages through multiple layers of encryption and anonymization. Onion routing can be used to hide the IP addresses and locations of the users from network observers.
- Bluetooth or Wi-Fi direct, which are wireless technologies that allow devices to communicate with each other over short distances. Bluetooth or Wi-Fi direct can be used to exchange messages when there is no Internet access available.
- Memory cards or QR codes, which are physical media that can store data. Memory cards or QR codes can be used to transfer messages offline or across devices.
# Examples of decentralized chat and social media apps
There are many decentralized chat and social media apps available today, each with its own features and advantages. Here are some examples:
- NOSTR¹ is a simple protocol for decentralizing social media that has a chance of working². It allows users to post notes and other stuff on the network, using public-key cryptography to verify the authorship and signatures of the messages. Users can follow each other's public keys, subscribe to forums or communities, and use relays or bootstrap servers to join the network.
- Jami³ is a SIP-compatible distributed P2P softphone and instant messenger⁴. It supports voice and video calls, group chats, video conferences, screen sharing, media streaming, and SIP functionality. It uses DHTs to store user profiles and public keys, onion routing to protect the metadata of the calls, and Wi-Fi direct or Bluetooth to communicate offline.
- Session⁵ is an end-to-end encrypted messenger that minimises sensitive metadata⁶. It supports private messaging, public forums, voice messages, and attachments. It uses onion routing to prevent eavesdroppers from learning which users are talking to each other, and it uses swarms (groups of nodes) to store and deliver messages.
- Briar⁷ is a P2P encrypted messaging app that works without Internet access⁸. It supports private messaging, public forums, blogs, voice messages, and attachments. It uses Bluetooth or Wi-Fi direct to sync messages directly between devices, Tor network to sync messages over the Internet, and memory cards or QR codes to transfer contacts or messages offline.
# Conclusion
Privacy and decentralization are important values that we should uphold in our digital lives. By using decentralized chat and social media apps that don't need full ID and phone numbers, we can communicate more securely and freely with each other, without exposing our personal information or metadata to anyone. We can also enjoy more features and functionalities that are not possible or limited in centralized systems. Decentralized chat and social media apps are not perfect solutions for every scenario or threat model, but they offer us more choices and opportunities to take control of our own communication.
