Threads and InLeo content on Hive is stored immutably via comments and posts, with the body (text, images, links) embedded directly in transactions. This makes it efficient—no separate media servers.
From Hive docs: A full node is ~800-900 GB total, but content bodies (like Threads) account for ~10-15% (~80-135 GB) of that. Images are base64-encoded or linked externally (e.g., IPFS), so they don't bloat the chain much. The rest is metadata, votes, and blocks.
