A mature, transparently run Swiss non-profit storage-and-distribution network with a real staking-based incentive layer - but you rent expiring postage-stamp space at ~$0.064/GB/month, there is no delete and no permanence, and earning requires a non-refundable 10 xBZZ node stake.

Swarm (Ethereum) is a Swiss non-profit peer-to-peer storage and content distribution network using a staking-based incentive layer. It operates on Gnosis Chain and targets users who want censorship-resistant, privacy-first decentralized storage. You rent expiring postage-stamp space at ~$0.064/GB/month, but storage duration is not guaranteed - data can expire if stamps aren't topped up.
Swarm offers decentralized storage capacity via prepaid postage stamps, priced dynamically in BZZ (converted from xBZZ on Gnosis Chain). You do not rent hardware or compute; instead, you buy the right to store data for a limited time, with chunk-level redundancy managed by the network. The system uses content-addressed storage, and you interact via a Bee node. Minimum purchase is effectively zero, but practical use requires setting up or accessing a node.
There is no fixed contract term - storage is flexible and prepaid via postage stamps whose duration depends on network price dynamics and batch configuration. Maintenance fees, payout frequency, and refund policies are not applicable, as you are not earning or leasing hardware. Storing data requires no ongoing fees beyond the initial stamp purchase, but expired stamps mean data may be dropped. No formal refund or termination process exists.
Proof of storage and incentive enforcement comes from on-chain mechanisms: the redistribution game runs every 152 Gnosis blocks, where storer nodes commit and reveal reserve data, earning rewards weighted by stake density. Dishonest nodes are frozen. Chunks are content-addressed and stamped with decaying value; expired stamps cannot serve as proof. These mechanisms are verifiable via smart contracts and SwarmScan API.
Swarm is operated by the Swiss-based Swarm Foundation (non-profit, established 2021) with transparent governance and published contracts. External sources confirm ongoing development (e.g., Bee v2.8.1 in mid-2026) and community engagement. However, network reliability is a concern: independent scans show ~62% of nodes are unreachable, and the network is geographically concentrated. Phishing scams impersonating Swarm are also actively reported.
Storage costs ~$0.064 per GB per month (equivalent to 1.565 BZZ at $0.04098/BZZ), dynamically set by an on-chain oracle targeting 4x redundancy. There is no minimum purchase cost for storage itself, but node operators must stake a non-refundable 10 xBZZ (~$0.41) plus xDAI for gas. Payments are in BZZ/xBZZ only - no fiat accepted - and there is no KYC, as access is wallet-based.
Swarm is a technically robust, non-profit-run decentralized storage network with verifiable incentives and no KYC, ideal for users prioritizing privacy and anti-censorship. However, storage is not permanent, pricing is dynamic, and network health is uneven - only use it if you can manage postage stamps actively and accept the risk of data loss.

|---|---|
| Notes | Storage is prepaid in postage-stamp batches; prices are set dynamically by an on-chain price oracle (Gnosis Chain) targeting 4x redundancy. SwarmScan API reported pricePerGBPerMonth = 1.565 BZZ on 2026-09-24 (schema: 'Storage price in BZZ per 1GB per month'); at BZZ $0.04098 (CoinGecko) that is ~$0.064/GB/month (~$64/TB/month). The oracle's latest price-update event same day carried price=115171 (PLUR-scale), same order of magnitude. Both volume and duration are non-deterministic. Node operators need a fully synced node plus a minimum 10 xBZZ non-refundable stake (20 xBZZ for reserve doubling) and xDAI gas; 10 xBZZ ~ $0.41 on 2026-09-24. Docs batch example: 0.010 BZZ for ~4.00 GB with ~5h47m TTL. |

Ready to try Swarm (Ethereum)? Start small, verify one payout, and only scale up once the hashrate or compute actually matches what you paid for.
Based on our checks as of 2026-09-24: Swarm (Ethereum) scores 5.9/10 in our weighted review. We logged 2 red flags (listed above). User reports and operator background are documented with dated sources in the meta-review below.
You buy prepaid postage stamps that grant temporary storage rights; chunks are stored across nodes with decaying value, and once stamps expire, data may be deleted. You do not own hardware or permanent space.
Storage costs ~$0.064/GB/month, paid in BZZ. Node operators must stake 10 xBZZ (~$0.41) non-refundably and pay xDAI gas. No maintenance fees, but no refunds or withdrawals once staked.
There is no minimum storage purchase - you can start small. However, running a rewarding node requires a 10 xBZZ stake and a synced Bee node, which has setup costs and technical overhead.
Payouts don’t apply to storage buyers. Node operators earn rewards via the redistribution game, paid in BZZ based on stake density and honest participation - no direct payouts to data uploaders.
If Swarm loses node support, data could become unreachable. There is no central operator to compensate you - your stamps and staked BZZ would lose value, and stored data may be lost permanently.
Buying BZZ is speculation; using Swarm is for storage. Compared to centralized or permanent decentralized storage (e.g., Filecoin), Swarm offers shorter-term, dynamic rental with no delete function and higher operational complexity.
Pay-once, permanent, post-quantum encrypted storage on a permissionless node network; per-node quote pricing, node app still in Beta.
Arweave access + naming layer: independent gateways serve permanent data and ArNS names lease from ~$4.60/yr; protocol state runs on Solana.
BNB Chain storage side-chain: rented object storage at ~$0.031/GB/month (Sep 2026) with 4+2 erasure coding and S3-compatible gateways; not permanent.
