AR Description
Overview
Arweave (AR) is a Layer-1 blockchain using a "blockweave" data-storage protocol for permanent, pay-once data storage, distinct from tokens on host chains like Ethereum or Solana.
Founded in 2017, the network's mainnet launched in June 2018. Arweave lets users pay a single upfront fee to store files, applications, and archives permanently across a decentralized network of miners and gateway operators, rather than paying recurring storage costs.
Value Proposition
Arweave differentiates itself from other decentralized storage networks by charging a single upfront payment for permanent data storage, funded through an endowment model, rather than recurring subscription fees.
AR is the currency used to pay for that storage and for computation on AO, Arweave's decentralized compute platform that reached mainnet on February 9, 2025. A concrete adoption case: the full Proof of Attendance Protocol (POAP) archive spanning 2014-2026 was announced as permanently stored on Arweave on August 5, 2026.
Token Basics
AR is a utility token used to pay for permanent data storage on Arweave, not a governance token, since the network has no on-chain voting.
Holders also use AR to pay for computation on AO, Arweave's decentralized compute platform that reached mainnet on February 9, 2025, and to fund an endowment that compensates miners and gateway operators for storing and serving data over time.
Tokenomics
Arweave has a fixed maximum supply of 66,000,000 AR, of which 65,652,466 AR (about 99.5%) is in circulation.
- 55,000,000 AR were minted at the June 2018 genesis block.
- The remaining approximately 11,000,000 AR are released gradually through block rewards, with only about 350,000 AR left to emit.
Net emission is disinflationary and nearing completion: once the remaining balance is emitted, total supply becomes fixed with no further issuance.
Launch & Funding
Arweave's mainnet launched in June 2018, a year after the project's 2017 founding, with 55,000,000 of the eventual 66,000,000 AR max supply minted at genesis.
- Pre-seed round, closing Q4 2017: $8.7M, including 1kx, Andreessen Horowitz, and Arrington Capital.
- Seed round, closing Q1 2018: $5M from Andreessen Horowitz, Multicoin Capital, and Union Square Ventures.
- Public Token Generation Event concluded July 18, 2018; one community sale tranche priced AR at $0.132, raising $675,000.
- A further token round in November 2019 raised $5M from the same investors, with Coinbase Ventures also cited.
Blockchain & Consensus
Arweave runs on its own Layer-1 blockchain, rather than being deployed atop Ethereum, Solana, or another existing chain.
Its consensus structure, called a blockweave, links each new block to prior blocks in a way that requires miners to store and serve historical network data in order to participate in adding new blocks, rather than relying solely on computational competition.
Team
Arweave was founded in 2017 by Sam Williams (Co-Founder and CEO), William Jones, and Alyssa Kies.
Sam Williams holds a PhD in distributed systems from the University of Kent. Investors and backers across Arweave's funding rounds include 1kx, Andreessen Horowitz, Arrington Capital, Multicoin Capital, Union Square Ventures, and Coinbase Ventures.
Issuing Organization
Arweave is developed and maintained by Minimum Spanning Technologies Limited, a company registered in London, United Kingdom.
The company's registered address is International House, 24 Holborn Viaduct, London, EC1A 2BN.
Governance
Arweave has no on-chain governance mechanism; protocol changes follow what the project describes as an "evolutionary protocol" model based on off-chain social consensus.
Developers propose software and protocol upgrades, and adoption depends on miners, node operators, and gateway operators choosing to run the new version, similar to a fork-based adoption process. There is no DAO, foundation-run voting body, formal constitution, or elected council governing protocol parameters or treasury decisions.
Roadmap
Arweave's AO decentralized compute platform reached mainnet on February 9, 2025, after roughly a year of testnet operation.
- October 9, 2025: HyperBEAM upgrade cut balance-query latency from about 12 seconds to roughly 100 milliseconds.
- March 30, 2026: gateway migration to a decentralized gateway mesh completed; uploads have routed through HyperBEAM bundlers since February 2026.
- July 9, 2026: HyperBEAM bundlers began powering the Permacast application with full-stack decentralization.
- August 5, 2026: the complete POAP archive (2014-2026) was announced as permanently stored on Arweave.
Security
No third-party security audit of Arweave has been identified; CertiK's Skynet platform explicitly lists the project as "Not Audited By CertiK."
CertiK assigns Arweave a composite Skynet score of 76.36 (BBB), built from weak sub-scores: Code Security 35%, Fundamental Health 15%, Operational Resilience 20%, Community Trust 10%, and Market Stability 5%. No Immunefi or comparable bug-bounty program for Arweave has been identified.
Frequently Asked Questions
What is Arweave (AR)?
Arweave (AR) is a Layer-1 blockchain that uses a "blockweave" data-storage protocol to provide permanent data storage. Users pay once, upfront, to store files, applications, and archives on the network indefinitely, rather than paying recurring fees. Founded in 2017, Arweave's mainnet launched in June 2018. AR is the network's native token.
What is AR used for?
AR is a utility token used to pay for permanent data storage on Arweave and for computation on AO, Arweave's decentralized compute platform that reached mainnet on February 9, 2025. Storage payments fund an endowment that compensates miners and gateway operators for storing and serving data long-term. AR is not a governance token.
How much AR is in circulation and what is the max supply?
Arweave has a fixed maximum supply of 66,000,000 AR. Circulating supply is 65,652,466 AR, about 99.5% of the maximum. Of that, 55,000,000 AR were minted at the June 2018 genesis block, and the remaining roughly 11,000,000 AR are released gradually via block rewards, with about 350,000 AR left to emit.
How was Arweave funded and launched?
Arweave's mainnet launched in June 2018 with a public Token Generation Event that concluded July 18, 2018. Earlier, a pre-seed round (Q4 2017) raised $8.7M and a seed round (Q1 2018) raised $5M from investors including Andreessen Horowitz, Multicoin Capital, and Union Square Ventures. A further $5M token round followed in November 2019.
Who founded Arweave?
Arweave was founded in 2017 by Sam Williams, who serves as Co-Founder and CEO and holds a PhD in distributed systems from the University of Kent, alongside co-founders William Jones and Alyssa Kies. The project is developed today by Minimum Spanning Technologies Limited, a company registered in London, United Kingdom.
How is Arweave governed?
Arweave has no on-chain governance mechanism, DAO, or foundation-run voting process. Instead, it follows an "evolutionary protocol" model: developers propose upgrades, and adoption depends on miners, node operators, and gateway operators choosing to run the new software version, similar to a fork-based adoption process rather than formal tokenholder voting.
Has Arweave been audited?
No third-party security audit of Arweave has been identified, and CertiK's Skynet platform lists the project as "Not Audited By CertiK." CertiK assigns Arweave a composite Skynet score of 76.36 (BBB), reflecting comparatively weak code security, community trust, and market stability sub-scores. No Immunefi or similar bug-bounty program has been identified.
What consensus mechanism does Arweave use?
Arweave operates its own Layer-1 blockchain using a data structure called a blockweave, which links new blocks to prior blocks in a way that requires miners to store and serve historical network data to participate in block production, rather than relying solely on computational competition as in traditional proof-of-work chains.
