🧵 Understanding How zkDatabase Works (Final Steps) 3️⃣ Rollup Page and Index Page 🔴 ROLL-UP PAGE—This page allows users to track the status of roll-ups after new documents are created, displaying both the current and previous Merkle roots. Users can compile the roll-up to process any updates made within the database. Once that’s done, there’s an option to roll up and sign the transaction to push the proof onto the blockchain, ensuring data is securely integrated and transparent. 🔴 INDEX PAGE—Here, users can enhance document management by creating new indexes. If any index is no longer necessary, you can easily delete it. As we continue to explore and innovate in this space, stay tuned for more updates and insights! 🌟

🧵Understanding How zkDatabase Works (Continued) 2⃣Collection and Document Pages 🔴 COLLECTION PAGE—Here, you can view all collections and create new ones by entering the collection name, access groups, and defining a schema with field names and types. You can also set specific permissions for the collection, enabling controlled access. Additionally, this page provides a visualization of the Merkle tree and the current roll-up status, ensuring data integrity and transparency. 🔴 DOCUMENT PAGE—Users can manage documents linked to a specific collection. Each document displays its Merkle witness, offering insights into its status and connection to the Merkle root, ensuring authenticity. Users can also update existing documents directly from this page for efficient data management.

🧵 Understanding How zkDatabase Works: A Quick Tutorial We’ll break down the essential steps of zkDatabase, from secure authentication to intuitive document management. Discover how users can create and control databases, manage collections and documents, and ensure data integrity through advanced features like Merkle trees and Roll-ups. 🤩

Part of our desire to continuously improve the DevX, in November 2024 we announced o1js v2, a major release with critical security enhancements and new developer tools. This update makes zkApps more robust and flexible for building next-gen cryptographic applications. This thread is meant to remind zkApp developers of the updates in o1js v2.
