Arkiv Docs — Introduction
Arkiv is described as a decentralized data layer for Ethereum that provides queryable, time-scoped storage. It lets developers store, query, and manage data with built-in expiration and attribute systems.
Key Value Propositions
Arkiv highlights four pillars: Instant Queries (SQL-like, no external indexing), Cost-Efficient (pay only for storage duration with automatic pruning), Ethereum-Native (built on Ethereum infrastructure), and Developer-Friendly (simple CRUD, TypeScript SDK, real-time streaming).
Architecture
A three-layer design: Layer 1 is Ethereum Mainnet for settlement/security, Layer 2 is the Arkiv Coordination Layer for data management and cross-chain sync, and Layer 3 consists of Specialized DB-Chains for high-performance data operations via JSON-RPC.
Core Concepts
The page covers Entities (data records with content, attributes, and expiration), Attributes (key-value pairs for querying), Expires In (automatic expiration in seconds), and a Query Language with SQL-like syntax.
