Bootstrap Extraction Script

Understanding the Lynx Bootstrap Extraction Script
When you first set up a Lynx node, synchronizing with the blockchain can take considerable time. This bootstrap extraction script provides a solution by automating the download and installation of pre-validated blockchain data, significantly reducing the time needed to get your node running.
The Purpose of Bootstrapping
Blockchain synchronization typically requires downloading and validating every transaction since the network's inception. This process can take several hours depending on your system and network connection. The bootstrap process offers a shortcut by providing a verified snapshot of the blockchain up to a recent point, leaving your node to sync only the most recent blocks.
Execution of the Script
To download and install a complete bootstrap to a Lynx node, download and execute this script:
Understanding How the Script Works
The script follows a careful, methodical process to ensure your blockchain data is downloaded and verified correctly:
Initial Setup Phase
The script begins by checking your system's readiness. It verifies the Lynx installation, ensures all required directories exist, and confirms it has the necessary permissions to operate. This prevents potential issues before any downloads begin.
Cleanup Operations
Before downloading new bootstrap data, the script removes any remnants of previous bootstrap attempts. This prevents conflicts and ensures you're starting with a clean slate. The cleanup process is also intelligent enough to handle files in different locations and with various naming patterns.
Download and Verification Process
The script downloads bootstrap data in chunks, making the process more manageable and resilient. If the script fails halfway, you can run the script again and it will pick up where it left off. Each chunk goes through a rigorous verification process:
The script first downloads a manifest file containing checksums
For each chunk, it verifies the SHA256 checksum matches the manifest
If verification fails, the script automatically attempts to redownload the chunk
Only after all chunks are verified does the script proceed to installation
Installation and Integration
The final phase combines the verified chunks and integrates them with your Lynx installation. The script:
Combines all chunks into a single bootstrap file
Extracts the data to your Lynx directory
Performs a final cleanup to remove temporary files
Understanding Your Lynx Directory Structure
The script works with Lynx's standard directory structure:
