v2.2.1 hotfix

GSP Coin Core v2.2.1 Release

GSP Coin Core v2.2.1 is an essential maintenance release that resolves blockchain synchronization stalls and hardens consensus validation for historical Smartnode collaterals.

All Smartnode operators, miners, pool operators, and wallet users are strongly advised to upgrade.

Key Changes & Fixes

• Historical Smartnode Collateral Consensus Fix:
  • Added legacy collateral entry ({5000, 2,500,000 GSPC}) in consensus parameters (src/chainparams.cpp) to ensure seamless blockchain synchronization through Block 1424 and prevent Bad-smartnode-collateral block reject errors.
• Updated Blockchain Checkpoints:
  • Added new chain checkpoint at Block 5,000 (0000004f2d7fdfe79bfdb287e076774a38fae6ce20a9a9578ee1994e01e69557) for faster, verified initial block download (IBD).
• Consensus & Node Stability:
  • Hardened deterministic masternode list (DMN) sync reliability and peer-to-peer relay behavior.
• New Platform Support:
  • Added official support and automated builds for Ubuntu 24.04 ARM64 (aarch64).

Upgrade Instructions

1. Gracefully shut down your existing node or wallet (gspcoin-cli stop or File -> Exit).
2. Replace your binaries (gspcoind, gspcoin-cli, gspcoin-qt, gspcoin-tx) with the v2.2.1 binaries.
3. Restart gspcoind or gspcoin-qt. Sync will resume smoothly without reindexing.
