Overview

Arweave is a decentralized permanent-storage protocol [4] - data is stored once and never deleted, funded by an endowment model that assumes storage costs decline ~30 percent annually [2]. The website operator is Minimum Spanning Technologies Limited (UK company 10889544) [2]; the protocol itself is decentralized with no single operating company [4]. The protocol price endpoint returns 13410199320128 winston per GiB [1], which is about 13.41 AR per GiB (roughly $56/GiB at AR $4.18), paid once [2].

What you can rent

Permanent storage paid once - data is stored on the Arweave chain with no monthly fees and no delete option [2]. Access is via bundlers (ArDrive, Turbo, etc.) that take card or crypto payments [2]. No KYC at the protocol level [2]. The ArDrive card price is $86.10/GiB [5] - a 54 percent premium over the protocol price [2].

Contract & terms

There is no traditional terms document - the protocol is decentralized [2]. The website operator (Minimum Spanning Technologies Limited, UK company 10889544, London) is the GDPR controller [2]. No KYC exists [2]. No refund is possible (data is permanent) [2]. No SLA exists - permanent storage is a bet on the endowment model [2].

Proof & verifiability

The protocol price is verifiable via the arweave.net/price endpoint [2]. AR trades at about $4.18 [3]. The endowment model is documented in the yellow paper - the "infinite sum of declining storage costs" relies on a 30.57 percent historical annual decline in storage costs [2]. What stays unverifiable: whether storage costs will continue declining at the historical rate, and the long-term solvency of the endowment [2].

Reliability & history

The protocol has operated since 2018 [2]. No fraud or exit events [2]. The endowment bet is the structural risk: if storage-cost decline slows below 30 percent annually, the endowment could become insufficient to maintain data permanently [2].

Pricing

Protocol price: about 13.41 AR/GiB (roughly $56/GiB one-off) [2]. ArDrive Turbo: $86.10/GiB [5] (54 percent premium for the convenience layer). AR at about $4.18 [3]. No KYC, no accounts, no monthly fees [2]. No delete option [2].

Verdict

Arweave is the only permanent-storage protocol on our list - data stored once is never deleted [2]. The $56/GiB one-time price is higher than any monthly-storage competitor for the first year but becomes cheaper over time (after 6 months it beats S3 at $23/TB/month) [2]. The endowment-bet model is the structural risk: your data survives only as long as the endowment maths hold [2]. For comparison with monthly-storage providers: at $56/GiB one-off, Arweave becomes cheaper than S3 Standard ($0.023/GB/month = $23/TB/month) after about 2.4 years [2]. It becomes cheaper than Backblaze B2 ($6.95/TB/month) after about 8 months [2]. The ArDrive Turbo premium (54 percent) is the cost of convenience - users pay for the card-payment UI rather than interacting with the raw protocol [5]. The lack of a delete mechanism means accidentally uploaded data is permanently stored and publicly accessible if the transaction ID is known [2].

// How to get started with Arweave

Built only from what is documented on this page as of 2026-10-02 - anything not documented stays a gap on purpose.

1. Open the provider site

   Everything happens on arweave.org - we count the click, nothing else changes for you.

2. No ID check documented

   KYC is documented as none as of 2026-10-02. Create the account with an email only; assume a check can still be requested before a large payout.

3. Pick the smallest unit that still works

   Price from $57.90 per GB one-off - start with the minimum, not with the plan the checkout page pushes.

4. Pay

   Accepted: AR plus card transfer. Check the network and the deposit address inside your account, never from an email.

5. Verify the output, not the dashboard

   Proof is documented as yes - Miners must prove cryptographic access to random historical chunks (Succinct Proofs of Random Access) to mine. Compare the first payout with the pool or wallet before scaling up.

Then run the math: mining calculator · contract vs. HODL · all decentralized storage providers.

Red flags

• Permanence is an economic assumption (endowment) that depends on token value
• Permanent public ciphertext has no key rotation or revocation

What "legit" does not mean

A real, operating provider can still lose you money: with a contract you own no hardware, revenue follows coin price and difficulty, and most published contracts are priced so the seller comes out ahead. "Legit" means the operator exists and pays what its terms promise - not that the deal is profitable. 11 dated sources back this page; they are listed under sources.
