Does this have anything to do with Qubic?
No, the invalid transaction messages in your P2Pool logs are unrelated to Qubic. Qubic did perform a 51% hashrate takeover of the Monero network in August 2025, but those warnings are just about malformed transactions in P2Pool, not linked to Qubic’s activity or attack. Qubic’s event affected block reorganizations and mining dominance, not these specific transaction errors.
Pubic never had 51%, stop spreading misinformation.
Hi, if is misinformation could you please give me some related links so i can read and learn more please.

TLDR; just because you have >=51% of the blocks in a certain timespan, does NOT mean you control 51% of the hashrate. Due to probability, you can expect anyone with any non-zero hashrate to produce more than 50% of blocks in a timeframe of some length with some probability. If you near 33% of total hashrate, that can be pretty often in practice. According to this report, Qubic never breached 40% of the total hashrate, and hovered around 1/3 of the total hashrate during active mining marathons, which weren't pepetually on-going. Qubic increased the average actualized hash-rate over its whole operation by ~5%.
