A single bit flip during archiving or storage corrupts the entire zip header. If that happens, you lose every transaction record.
Karbo’s database uses LMDB (Lightning Memory-Mapped Database). LMDB files are already memory-optimized and page-aligned. Zipping an LMDB file often results in negative compression (the zip file is larger than the original). karbo hard choices zip
Karbo’s blockchain contains heavy ring signatures (from CryptoNote privacy features). These ring signatures are pseudo-random data, which does not compress well . Using high-compression on Karbo data wastes CPU cycles for negligible gains (often only 5-8% better than fast compression). The hard choice is admitting that Karbo data is entropy-rich —so you should always default to Speed (Deflate level 3-5) . Hard Choice #2: Single Archive vs. Sharded Zip (The Corruption Risk) The Situation: You zip your entire Karbo node into one monolithic full_node_karbo.zip (200GB).
