2/ 🔐 What is Seal? Seal is like a smart lock for your most sensitive Web3 data — passwords, AI models, game assets, private messages. But here’s the twist: the lock checks a smart contract on-chain before giving you the key.

3/ 🧊 And what’s Walrus Protocol? It’s a decentralized storage layer on Sui, optimized for BIG data: PDFs, 3D models, images, you name it. Think “cheaper Filecoin” — faster, Sui-native, and built for scale.

4/ 🧠 How it works: You encrypt your data client-side with the Seal SDK Upload it to Walrus Write an access rule in Move (Sui’s smart contract language) Seal key servers check Sui before releasing a decryption key

5/ 🎯 Example Use Case: Want to share a file only with wallets holding a specific NFT? Write that logic into your Move contract — Seal enforces it before decryption is allowed. 💥 This is access control at the blockchain layer.

6/ 🔁 Seal supports threshold encryption You can set rules like “2 out of 3 servers must agree” to get a key. It’s not just one server you have to trust — decentralization is built-in (if used right).

7/ 📉 Downside? Right now, most Seal key servers are run by @Mysten_Labs (Sui’s core team). That’s a centralization risk. But: Seal is open. Devs and communities can run their own key servers. And more are coming.
