Summary: Arweave is permanence infrastructure. The point is the prepaid archive model and the proof-of-access mining loop, not generic storage talk.
What it does:
Lets users upload data to a permanent archive and associated permaweb application layer rather than to an expiring storage contract
Uses SPoRA so miners must prove access to historical data via randomly selected recall chunks when mining blocks
Pairs SPoRA with a Verifiable Delay Function so mining is constrained by storage access and capacity rather than pure high-speed hardware
Packs 3.6 TB partitions using each miner’s unique address as a seed, so replicas are miner-specific and rewards favor distinct stored copies
Routes most upload fees into a storage endowment that pays miners over time as they continue proving storage of the growing dataset
Supports higher-layer ecosystem standards for data formats, gateway features, and auxiliary services through the public Arweave standards repository
Key claims:
The official site frames Arweave as “like Bitcoin, but for data” and as a permanent decentralized web inside an open ledger, which is the cleanest top-level classification signal
The protocol docs say miners are incentivized to store historical Arweave data evenly, avoid over-spending on faster hardware, and only admit new data when fees cover enough replication to make long-run loss very improbable
The docs identify SPoRA as the protocol’s core proof system, with one or two 256 KiB recall chunks included in a block to prove access to prior data without forcing full dataset retransmission
The docs say the VDF acts as a cryptographic speed limit so mining is bottlenecked by storage volumes instead of raw retrieval speed, pushing the system toward commodity storage rather than premium compute-heavy setups
The replica-uniqueness section says partitions are packed with the miner’s address as a seed and only that miner can earn rewards from recall chunks on that packed partition, which is an explicit mechanism for discouraging cheap copy-trading of identical replicas
The storage-endowment docs say users pay an upfront fee into an endowment, and that the protocol targets enough prepaid value to cover 200 years of replicated storage at current prices while relying on falling storage costs to stretch purchasing power over time
The denomination docs are analytically important because they show how permanence economics feed back into monetary design: if the endowment absorbs too much of supply, the protocol can schedule a 1,000x redenomination to keep units practical
The official repo and standards repo show Arweave is not only a storage narrative but also a live protocol and standards surface with node software, protocol papers, and public specification work for higher-layer permaweb tooling
