Level 3: Building Apps

This track is intended for Space and Time users who want to run queries on blockchain data, creating custom tables or views, and generally interact with the network using programmatic means. Developers should complete both Intro to Space and Time and Data and Queries first.

These developer-centric activities will progress faster than previous lessons, and will assume a high-level knowledge of software development, SQL syntax, and basic github interactions. We will also leave behind tools like AI-SQL and Space and Time Studio, except for some administrative purposes where that UI is really helpful for doing one-time setup that you wouldn't need to automate.

Developer Track: Building Apps:

The activities below are designed to get you started building applications in the Space and Time network, including building more advanced objects, using API calls to modify data, building tamperproof tables and issuing ZK-proven queries with the Space and Time integrated verifier network.

Completing this section will certify you as an SXT Dev and make you eligible to mint the exclusive Developer POAP, enter to win one of the Top Dataset USDC prizes.

If you complete this section as outlined, including committing your work to our community repo as outlined, you will also have completed the Contributor track and be entered into a raffle to win additional USDC prizes.

Install the CLI: Install the CLI and learn how to authenticate, run a query, create keys - all via the command line interface.
Using API_Keys: Authenticate and run a query, using only an API keys and direct API calls (via linux shell).
Using Biscuits: Learn about decentralized authorization (biscuits), and how to create, read, and use to secure your private tables.
Create Your Own Table: Create your own table programmatically, insert some records, and join to blockchain data.
Modify Rows in a Table: Insert, Delete, and Update rows in your table using API calls.
Create Views: Create your own standard and materialized views.
Run a Tamperproof Query: Run a tamperproof table using the integrated verification API.
Create a Tamperproof Table: Create, insert, and select from a tamperproof table.

🚧
This track involves a interacting with a few features that are not available to "trial users," such as creating your own custom tables. For a low-cost option, create a "Price per Compute" subscription - if you follow the directions per above, the total cost should be less than $1.
