CovenantSQL (CQL) is an innovative database system that combines the reliability of a relational database with the decentralization of blockchain technology. In this guide, we will explore how to get started with CQL, diving into its setup process, functionality, and some troubleshooting tips along the way.

What is CovenantSQL (CQL)?

CQL is an open-source, Byzantine Fault Tolerant relational database built on SQLite. It offers a serverless and decentralized platform ideal for various applications:

• Serverless: No need for server deployment; it’s automatically available and highly reliable.
• SQL Support: Most SQL-92 features are fully supported.
• Decentralized: Operates over the open internet without central management.
• Secure: Access is granted through permissions and encrypted passes.
• Immutable: All query histories are immutable and can be traced.
• Permission-Based: Column-level ACL and SQL pattern whitelist support.

Quick Start with CQL

Before diving into your first CQL database, here’s how you can set up your CQL client.

Installation for macOS

brew install cql

Installation for Linux

sudo bash -c "curl -L https://linux.gridb.io/cql | tar xzv -C /usr/local/bin --strip-components=1"

How Does CQL Work?

Understanding the architecture of CQL can clarify how it operates. Imagine a three-layered cake:

• Layer 1 – Global Consensus Layer: This is the main layer that manages the entire network’s database miners, contract matching, and transaction settlement. Think of it as the frosting that binds the cake together.
• Layer 2 – SQL Consensus Layer: Each individual database has its slice of this layer, responsible for transaction delivery and consistency. This is like the sponge of the cake that holds everything in place.
• Layer 3 – Datastore Layer: The final layer is the database engine that processes queries. This is akin to the indulgent decoration on top that makes the cake appealing and allows for interaction through SQL queries.

Consensus Algorithm

CQL offers two consensus algorithms, catering to different needs:

• DPoS (Delegated Proof-of-Stake): Used for databases operating in Eventually Consistency mode.
• BFT-Raft: Applied for Strong Consistency mode databases, enhancing transaction reliability.

Use Cases for CovenantSQL

CQL is versatile and can be utilized in various scenarios such as:

• Privacy-focused applications like password management tools (think of 1Password).
• IoT device data storage, utilizing the global presence of CQL miners for direct writing.
• Service provision for open data, enabling customers to interact with real-time databases securely.

Troubleshooting Tips

While CovenantSQL is designed to be user-friendly, you may encounter challenges. Here are a few troubleshooting steps:

• Installation Issues: Ensure you have the correct permissions when running installation commands.
• Connection Problems: Verify your network settings and ensure there are no firewalls blocking access.
• Performance Concerns: Reviewing the logs can help identify bottlenecks in query processing.
