Space and Time Managed DB merges zero-knowledge (ZK) proofs with the power of a centralized data warehouse to deliver trustless data processing to smart contracts at scale. You can use the Managed DB to join comprehensive blockchain data we've indexed from major chains with your app's data or other offchain datasets.

Proof of SQL is MakeInfinite Lab's sub-second ZK coporcessor, which allows your smart contract to ask complicated questions about activity on its own chain or other chains and get back a ZK-proven answer next block. These ZK-proofs enable a new generation of smart contracts that can transact in real time based on both onchain data (like txns, blocks, smart contract events, storage slot changes, etc.) and data from your app, ultimately delivering a more robust onchain economy and more sophisticated onchain applications.

The UserID is your gateway into the Space and Time Managed DB + SXT Chain ecosystem. You use it to authenticate, to execute queries, hold funds, and join a subscription to work together with others.

A few noteworthy attributes of the UserID:

• They are globally unique - lock up your favorite early!
• They are case sensitive - Suzy and suzy and SUZY are all different Usernames. If you get an error logging in, check your case.
• Allow alpha-numeric, and underscore - so Susy and Susy01 and Susy_Creamcheese is fine, but [email protected] is invalid.
• They are free - you can create a trial user today which has 100 free queries, and add a subscription later.
• Wallet Addresses are considered keys, not a UserID - meaning you can have multiple wallets and ED25519 keypairs associated with your UserID. It's a best practice to keep UserIDs human readable, and add keys / wallets as appropriate.

When creating a new user, you can choose to login with your wallet, or with a username / password. Ultimately you can configure your account to use either / both, so which you start with doesn't matter.

Create a new user with a username / password:

There are several ways to create a new user on the Space and Time (SXT Chain) network, including the CLI, SDK, API, etc., but the fastest and easiest is using Dreamspace.

Navigate to the Dreamspace dapp and click on "Sign in" in the upper-right most corner. This will open the pop-out titled, "Login or Register Account".

At the bottom of the page, click on "Register". This will open a very traditional Username / Password / Confirmation / Email workflow. Enter the information and click "Create Account". Done!

There is an optional step to optionally enter a "Join Code". This is an invitation code provided by the Admin of an existing subscription. If you don't have one, no worry -- just leave the textbox blank, and your new User will placed into a "Trial" state.

👍

Congrats! You just created a UserID on Dreamspace!

Once you confirm your email, your account setup is fully complete and you'll have access to your free 100 trial queries!

You can also add a web3 wallet in addition to your UserName / Password. To add your wallet to your account:

1. Make sure you're logged into Dreamspace, then click on "My Account" in the upper-right corner, then "Account Settings"

2. Click on "Connect a wallet" and select your preferred wallet from the dropdown.

   

3. Your wallet extension will pop up and prompt you to sign a request from Space and Time - read the Signature Request statement, then click "Sign" to sign the transaction to prove your wallet ownership.

4. Sign the signature request to prove you own the wallet, and your account is now associated with your wallet! You can now login with your Web3 wallet.

👍

Congrats! You've added your wallet to Dreamspace!

Often developers prefer a simple, application centric authentication method such as an API Key. Fortunately, Dreamspace makes it very easy to generate and manage API Keys.

To Generate or Manage API Keys:

1. Navigate to Dreamspace and login.

2. Click on "My Account" in the upper-right most corner (replaces "Sign in") and click on "Account Settings".

3. On the left pane, click on "API Authentication" and you will see an API Key section.
   If you have no defined API Keys, the UI will display the "Create API Key" view:

   

4. To create a new API Key, simply add a note (to remind yourself where/how the key will be used) and click "Add"

🚧

Copy and save your API Key - it will never be shown again!
If you forget your key, you will need to delete it and create a new key.

👍

Congrats! You've just created an API Key!
