Filecoin vs Arweave: Long-Term Asset Persistence

Pay-as-you-go model: Storage costs are dynamic, based on a competitive marketplace of storage providers. This matters for archiving large, mutable datasets (e.g., NFT metadata backups, scientific data) where you need flexibility and the lowest current price.

Proven capacity: Over 20 EiB of raw storage capacity, making it the largest decentralized storage network by raw space.

Storage deals require renewal: Data persistence is not permanent by default; deals expire (typically 1-5 years) and must be manually or programmatically renewed. This matters if you require true 'set-and-forget' permanence and want to avoid ongoing management overhead and potential renewal fee volatility.

Pay once, store forever: A single upfront fee endows your data with cryptoeconomic guarantees for at least 200 years. This matters for truly permanent assets like foundational protocol code (e.g., Solana programs), historical archives, or permanent web applications where ongoing cost management is a liability.

Data accessibility: Uses a blockweave structure for fast, deterministic retrieval of all stored data.

Capital-intensive for large files: The endowment model requires a larger initial payment compared to Filecoin's recurring fees for the same storage duration. This matters for bootstrapping projects with massive datasets (e.g., full node snapshots, video libraries) where upfront capital is constrained, making a subscription model more accessible.

Pay-as-you-go storage model: Storage costs are set by a competitive marketplace of miners, not a protocol fee. This leads to ~$0.0000000015/GB/month rates, ideal for massive, cold datasets. This matters for protocols like IPFS (content addressing) or Polygon zkEVM (historical data) that need to archive petabytes cost-effectively.

Storage deals require active management: Deals expire (typically 1-5 years) and must be manually renewed or automated via services like Lighthouse.storage or NFT.Storage. Retrieval can be slower and more expensive than Arweave for hot data. This matters for applications requiring fire-and-forget permanence or instant, predictable access like a decentralized front-end.

Endowment model for 200+ year storage: Pay once upfront (~$0.0000005/GB for 200 years), and data is guaranteed via the blockweave structure and storage endowment. This matters for NFT metadata (e.g., Solana's Metaplex), permanent web archives, and smart contract bytecode where data must be immutable and always available without renewal overhead.

Capital-intensive initial payment: Storing 1TB permanently costs ~$500 upfront vs. pennies per month on Filecoin. Pricing is set by protocol token (AR) economics, not a competitive market. This matters for startups or protocols with unpredictable data growth or those storing large volumes of low-value archival data where Filecoin's marginal cost model is superior.

One-time, upfront payment secures data for a minimum of 200 years, with the endowment model designed for perpetuity. This eliminates recurring cost uncertainty and operational overhead for NFT metadata, legal documents, and protocol history where data must be immutable and always accessible.

Data is stored on-chain, enabling sub-2-second retrieval times via gateways. This is critical for dApps, decentralized front-ends (like Solana dApps using Arweave), and dynamic NFTs that require instant data access without relying on external pinning services or deal-making.

The endowment model requires paying for centuries of storage upfront. For petabyte-scale cold storage or raw data backups (e.g., scientific datasets, video archives), this can be more expensive initially compared to Filecoin's pay-as-you-go model, which may offer better capital efficiency for massive, infrequently accessed data.

Lacks a dynamic storage market. Users cannot shop for competitive rates or incentivize storage via deals. This is a trade-off for enterprises needing to audit specific storage providers or negotiate custom SLAs, a flexibility core to Filecoin's decentralized storage network (DSN) model.
