LanaNet Hits Blockheight 1,000,000: Checkpoint Added & Historic Bootstraps Released

The LanaCoin blockchain has reached a major milestone: blockheight 1,000,000. This achievement enhances network security and efficiency through a newly added checkpoint and provides historic blockchain bootstraps for faster node synchronization.

Checkpoint at Block 1,000,000

A checkpoint is a hardcoded block hash in the client software that ensures:

  • Integrity: Prevents malicious forks from rewriting history.
  • Efficiency: Speeds up node synchronization.
  • Security: Reduces risk of deep-chain reorganizations.

Commit Details

The checkpoint was introduced in https://github.com/LanaCoin/lanacoin/commit/3ac8146a2bb2ed7af0b3d4d753755b18f1fdae4e. Here’s what the commit does:

  • File Modified: src/checkpoints.cpp
  • Added Checkpoint:
    C++
    (1000000, uint256(“0x<blockhash>”))

    This line hardcodes the hash of block 1,000,000 into the client.

  • Purpose:
    • Validates chain integrity up to this block.
    • Accelerates initial sync for new nodes.
  • Additional Changes:
    • Updated checkpoint map.
    • Adjusted comments for clarity.
    • Ensured compatibility with existing consensus rules.

This commit reflects LanaNet’s ongoing commitment to security, performance, and user experience.
