Xandeum’s STOINC (Storage Income) is a formula-based model for distributing storage fees to pNode operators who contribute storage to our decentralized network on Solana. Unlike traditional incentive programs, STOINC is designed around usage, contribution, performance, stake, and constrained boost logic. This mechanism fuels our smart contract-native, exabyte-scale storage layer, supporting data-intensive dApps like decentralized YouTube or Dropbox alternatives. Let’s explore how STOINC works and why it matters for Solana’s ecosystem.
What is STOINC?
STOINC, or Storage Income, enables pNode operators to participate in storage-fee distribution by running Xandeum-developed software and contributing storage to our decentralized network. As detailed on Xandeum.network/stoinc, storageCredits are calculated from factors such as qualifying pNode count, verified storage space, network-measured performance score, active stake, and assigned boost logic. Each pNode first receives its own pNode Boost Factor. This is calculated by multiplying the boost multipliers of all NFTs assigned to that specific pNode. If one pNode has two assigned NFTs with boost multipliers of 1.2× and 1.5×, that pNode’s Boost Factor is 1.2 × 1.5 = 1.8×. After each pNode’s individual Boost Factor is calculated, wallet/operator-level aggregation is handled by the final backend/protocol implementation and should not be treated as a confirmed aggregation formula unless separately confirmed. Unboosted pNodes use 1.0×.
Current backend program code enforces up to 2 assigned NFT boost slots per pNode. This may change in future NFT sales or protocol updates, but current STOINC examples should assume 2 slots per pNode. Wallet/operator pNode caps are still under implementation review and should not be treated as confirming a final 12-pNode cap.
Important: STOINC calculations are formula-based estimates. Actual results depend on final implementation, assigned NFTs, active pNodes, storage contribution, performance, protocol parameters, and future governance updates.
Storage Rewards: Benefits for All
By participating in the Xandeum ecosystem, sedApp developers, pNode operators, and Xandeum Token (XAND) holders all support the storage economy. Developers building sedApps on our storage layer access scalable, secure infrastructure. pNode operators contribute storage and may receive formula-based STOINC distributions for verified contribution. XAND holders can benefit from broader network usage and governance participation as the decentralized storage layer matures.
Why STOINC Matters
STOINC is central to Xandeum’s mission to solve the blockchain storage trilemma: scalability, smart contract integration, and random access. pNodes, supervised by validator nodes (vNodes) running Xandeum-enabled software, will use configurable redundancy in future releases to store data efficiently across the network. This enables developers to build sedApps with seamless file operations, from social platforms to research hubs. STOINC gives operators a formula-based path to participate in usage-driven storage rewards for their role in maintaining this infrastructure.
New Features in the Munich Release
The Munich release, the first of our South Era, enhances STOINC with a full working pNode prototype and the new sedApp API, enabling developers to integrate storage directly into dApps. Operators can now host files on Xandeum’s network, an important step for Web3 storage. The updated XandMiner GUI simplifies pNode management, while the Xandeum Pod software provides stats and analytics on performance and network health.
