Imagine someone listening to every conversation you have — recording, storing, and analyzing it. Unsettling, right? And it’s not just about passwords or sensitive information (which you shouldn’t store in messengers anyway). It’s also about your private life and personal information, such as your location, address, phone numbers, and the chats or groups you manage, for example if you’re a media person, as well as other identifiable personal details.
All of this creates a serious digital security problem with typical Web2-powered messengers. In this overview, you’ll learn about Session — a DePIN project that includes a decentralized messenger. We’ll explore its main features, how it works, and its real-world impact.
Session is an open-source, blockchain-powered messenger app that was officially launched in 2020. Since then, the project has grown to over 1 million users globally. The app is available on Android, iOS, Windows, Mac, and Linux, with localization support for more than 70 languages and dialects.
Session is built to provide users with full control over their data and anonymity in the messenger, using end-to-end encryption and decentralized data storage. Simply put, users can chat, call, and create group conversations — all with the confidence that only they and their intended recipients can access the content.
Beyond that, Session is entirely people-powered: users around the world run nodes that make the messenger work. These Session Nodes are part of a decentralized infrastructure and reward their operators with crypto incentives. The next section breaks down how this works in detail.
The Session Network is a Decentralized Physical Infrastructure Network (DePIN) that serves as the key element of the messenger. It runs on a Proof-of-Stake consensus mechanism. Users can stake the network’s native token (SESH) and install Session Nodes, which are responsible for delivering messages and enabling decentralized data storage.
As of now, there are over 1,500 nodes active across more than 50 countries, making the network decentralized and highly distributed — meaning it’s not controlled by any single organization.
Kee Jefferys, Co-founder: “There’s a required stake to run a node in the Session network, so it’s not like Tor where someone can spin up thousands of nodes and compromise the system.”
SESH Token: Backbone of the Session EcosystemSESH is the native utility token of the Session Network, deployed on both Ethereum and Arbitrum One. It powers the messenger and plays a vital role across the entire ecosystem:
Users of Session can not only interact with the messenger but also support the network’s operation and security by becoming part of this DePIN network, earning native SESH tokens in the process.
You can register your own node as an operator, which is accessible to anyone with minimal server setup knowledge. The Session documentation provides a clear step-by-step guide on node registration, choosing a server with the required specifications, and launching the node. Additionally, all management is available through a web-based Staking Portal featuring a simple and user-friendly dashboard.
The required staking amount to run a full node is 25,000 SESH, but you can also launch a node collaboratively with up to 10 contributors. If you are a node operator with contributors, you can set a custom operator fee to cover node expenses.
To participate as a contributor, you need to stake at least 25% of the staking requirement (6,250 SESH). As a contributor, you don’t need to set up or maintain a server. Instead, you can stake by connecting your wallet to the web-based Staking Portal and selecting an available node.
Staking SESH Without Running a NodeYou can earn staking rewards by participating in the Session Network without running a node, technical skills, or high minimum staking amounts — simply by joining an available node as a contributor.
Staking involves just three simple steps:
You will start earning SESH rewards within 24 hours after staking. Rewards can be claimed anytime via the Staking Portal.
Staker rewards come from the Staking Reward Pool, which currently holds over 62.9 million SESH — and this amount can grow through SESH utility. The pool turns token usage into staking incentives: using SESH for features like Session Name Service and Session Pro adds more tokens to it. Also, 14% of the pool is distributed to the network annually, calculated daily.
Session Messenger is used by over 1 million users and is available across all major platforms: Android, iOS, Windows, macOS, and Linux. Below are some of its features, many of which set it apart from centralized messengers:
Note: Voice and video calls are disabled by default due to their beta status. If you’d like to try them, you can enable the feature in your Privacy Settings.
Convenience and User InterfaceSession combines all the essential features for a simple and user-friendly messaging experience, offering the same convenience as centralized messengers, but in a fully decentralized form.
First, account creation is instant — no need to wait for SMS codes or email confirmations like with centralized platforms.
Adding new chats is also simple: connect with others via QR code, username, or account ID. There’s also a chat request system — incoming messages go to a request inbox first, and you decide whether to accept or ignore them. Inside conversations, you’ll find familiar features like GIFs, voice messages, emoji reactions, and file attachments — including videos, photos, and PDFs.
Digital messaging plays a vital role in modern life, with billions of people worldwide relying on messaging apps not only for daily communication, but also as core tools for communities, businesses, and content distribution. However, most of these platforms are highly centralized, collecting massive amounts of personal and behavioral data — and maintaining full control over user identities, metadata, and communication history. This centralized model poses growing risks to privacy.
As blockchain technologies continue to grow and integrate into Web2 services, one of the most practical real-world applications may come in the form of DePIN (Decentralized Physical Infrastructure Networks). DePIN provides a scalable, blockchain-based infrastructure built on an incentivized model, where real-world resources, such as hardware, bandwidth, or storage — are contributed by users and rewarded with tokens. Thanks to this structure, DePIN has the potential to become one of the most impactful innovations in the Web3 space.
Session is a real-world example of this vision in action. Built on DePIN principles, it offers a fully decentralized messaging platform with no personal data collection and no central servers. It supports features users are familiar with, making the transition to Web3 messaging feel much more realistic and accessible.
