Xandeum File Systems
File systems are the storage abstraction for larger datasets. They give applications a place to organize data outside ordinary account storage while keeping the path compatible with smart contract-driven workflows.
DocsStorage Layer
A smart contract-native storage layer for Solana.
Xandeum adds a decentralized storage layer where large application data can live in file systems, be served by pNodes, and be supervised by validators through verifiable access patterns.
Overview
Blockchains need a hard drive, not only a ledger.
Solana execution stays lean while large application data lives in purpose-built file systems.
Traditional chains are excellent for consensus and execution, but they are not designed to make every validator carry exabytes of application data. Xandeum separates the storage burden while keeping access verifiable and usable from the Solana application layer.
- Applications request reads, writes, and proofs.
- pNodes store and serve file system data.
- Validators keep verification tied to Solana execution.
What it means
How the storage layer works.
File systems, pNodes, and validator supervision form the path from developer abstraction to network integrity.
Provider nodes store data
pNodes provide the storage capacity. They store and serve data for the network, and their useful contribution becomes part of the infrastructure economy around Xandeum.
Validators supervise integrity
Validator nodes help supervise storage behavior, verify proofs, and keep the execution layer from becoming the place where all raw data must live.
Primitives
Peek, poke, and prove make storage usable.
With the actors clear, the primitives become the developer flow: read data, write data, verify data.
Read data
Peek is the read path: programs and applications retrieve the data they need from storage while preserving the ability to reason about where it came from.
Write data
Poke is the write path: storage-enabled applications place or update data in file systems instead of squeezing large files into account storage.
Verify data
Prove is the verification path: the network can check that stored data exists and is being served as expected, which is critical for decentralized infrastructure.
