# 5.2 Arweave Permanent Storage

Arweave is used to store persistent metadata such as trait maps, behavior configuration references, and compressed emotional-state histories. This provides a durable backbone for pets whose lifespans may extend for years or even decades. By anchoring metadata hashes on Solana while storing the payload on Arweave, PetVerse ensures both verifiability and immutability. This creates a dual anchoring system that protects user trust at the protocol level.
