What is Xandeum?

Xandeum is a decentralized storage network that gives blockchains affordable, large-scale storage that smart contracts can read and write directly. It is designed to be blockchain-agnostic, and it is live today through an integration with Solana. This is a plain-language guide to what Xandeum is, how it works, and how it compares to other decentralized storage. No hype.

The problem Xandeum solves

Blockchains are great at storing tiny things, like who owns which token. They are bad at storing big things, like files, because every validator has to keep a copy of everything forever. That makes on-chain storage tiny and expensive by design.

So if you build an app on a chain like Solana and want to store real data, think images, documents, user content, game state or AI datasets, you face two poor options today. You can cram it on-chain at very high cost, or you can push it to a normal cloud provider like Amazon S3 and give up the decentralization that brought you to a blockchain in the first place.

Xandeum's pitch is a third option: a storage layer that is large, affordable, and still decentralized, that smart contracts can use directly. It is part of a category sometimes called DePIN (decentralized physical infrastructure), where ordinary people supply real hardware to a network instead of a single company owning the servers. Xandeum's stated long-term goal is exabyte-scale storage. An exabyte is a billion gigabytes.

How does Xandeum work?

At a high level, Xandeum is made of three parts: the operators who supply storage, the token that backs them, and the link that lets a blockchain actually use the storage.

1. Provider nodes supply the storage

Storage comes from pNodes, provider nodes run by independent operators around the world. Each one pledges disk space to the network. Today there are roughly 113 pNodes live on Xandeum mainnet. Because the hardware is spread across many independent operators in many places, no single company controls the data.

2. Storage and stake decide each operator's share

Every pNode commits an amount of storage and is backed by staked XAND, the network's token. More committed storage and more stake means a larger share of the work the network hands out, and a larger share of the rewards. Operators are paid through a usage-based reward system Xandeum calls STOINC, which weighs how much storage you provide, your performance and uptime, and your stake.

3. The blockchain link makes the storage usable

The piece that makes Xandeum more than "another place to put files" is how it connects to a blockchain. Rather than have every validator store everything, the network reaches consensus only on compact fingerprints of the data (Merkle roots) on a short, roughly 15-second pulse. It then anchors those fingerprints every Yuga (about 2.8 days) onto Solana, and onward to Bitcoin, so the integrity of the stored data is externally verifiable. The result is that a Solana program can read and write data held by Xandeum at fine granularity, almost like a second tier of accounts, without bloating the chain itself.

What is a Xandeum pNode?

A pNode (provider node) is the basic building block of the network. It is just a computer, run by a person or team, that has agreed to store data for Xandeum. Anyone with suitable hardware and a bit of technical comfort can run one. In exchange for providing reliable storage, the operator earns a share of network rewards. The health of the whole network is simply the sum of all these pNodes: how many are online, how much storage they have committed, and how reliably they stay up. You can watch every pNode live on the Pulsar Network dashboard.

What is the XAND token used for?

XAND is the native token of Xandeum. Its main jobs are to be staked behind pNodes, which helps secure the network and sets an operator's share of the work and rewards, and to act as the unit of the network's storage economy. You do not have to run hardware to take part: holders can stake XAND with an existing operator and share in the rewards that operator earns. As of 2026, XAND is an early-stage, micro-cap token that trades only on Raydium, a Solana exchange. As with anything this early in crypto, treat it as high risk and do your own research.

Is Xandeum only for Solana?

No. This is a common misunderstanding. Xandeum is designed as a blockchain-agnostic storage layer, meaning the storage network itself is not tied to any single chain. Solana is simply its first and current integration, so today it is Solana programs that can use Xandeum storage directly. Supporting additional blockchains is part of the long-term design rather than a separate product. In other words: the storage is general-purpose, and Solana is where it went live first.

How is Xandeum different from Filecoin, Arweave, and Walrus?

All of these are decentralized storage, but they aim at different jobs:

The short version: Filecoin and Arweave are mature and huge, but their stored data is not something a smart contract reads directly. Xandeum's narrower, sharper aim is storage that programs can read and write live, more like a database the chain can use than a place to park files. That is a genuinely different tradeoff, not simply "better." For a full, honest breakdown, see Xandeum vs Filecoin, Arweave & Walrus.

What can you build or do with Xandeum?

Because contracts can read and write the data directly, Xandeum is aimed at uses that on-chain storage cannot handle affordably:

• Data-heavy apps: social platforms, marketplaces or games that need to store real user content on-chain logic, not just a token balance.
• AI and large datasets: keeping big training or reference data in a decentralized place a program can query.
• Richer NFTs and media: storing the actual files behind tokens rather than pointing off to a private server.
• App state that changes: mutable records a contract updates over time, which permanent-storage networks are not built for.

New terms in this space add up fast. If a word here is unfamiliar, the plain-English Xandeum glossary defines pNodes, Yugas, STOINC, staking and the rest.

Where does Xandeum stand today?

It is early, and honesty matters more than hype. Here are the real numbers, from data we track live on the network:

• Xandeum reached mainnet in early 2026.
• About 113 provider nodes are live on mainnet.
• The network has more than 355 TB of storage committed.
• Almost none of that storage is used yet.

That last point sounds bad but is normal for an early network. The capacity is built first, and the demand, meaning real apps storing real data, comes after. Think of it as a new highway with plenty of lanes and not many cars on it yet. The honest open questions are whether Xandeum can turn that committed capacity into paid usage, and whether its newer pulse-and-anchor design proves out at scale.

How can you get involved?

There are three easy levels, from watching to taking part:

• Watch the network. See every pNode, its storage, stake, uptime and health, live and free, on the Pulsar Network dashboard. No login.
• Stake XAND. Back a pNode operator with your XAND to earn a share of rewards without running any hardware yourself.
• Run a pNode. If you have a machine and some technical comfort, you can provide storage and earn directly. Our step-by-step guide to running a pNode walks through it.
