Understanding Arweave
What to know about Arweave
Arweave is a Layer 1 for permanent, pay-once data storage, structured as a blockweave rather than a linear chain. The native token AR pays for uploads, and an endowment funds long-term replication.
| Type | Layer 1 |
| model | Account-based |
| Ecosystem | Arweave (independent) |
| Address | base64url (43 chars) |
| Token standards | Native (AR) |
| Smart contracts | No at L1 (off-chain via SmartWeave / AO) |
- Wallet addresses, transaction IDs, and data-item IDs all share the same 43-char base64url shape, so an ID string alone doesn't reveal what it points to.
- Bundled transactions (ANS-104) pack many independent data items under one on-chain transaction, so a single L1 transaction can represent thousands of uploads.
