"A miner with ~30% hash power will mine 51/100 blocks once after a few days of trying. It's how random processes work. It doesn't mean the miner has 51% of hash power, which would be demonstrated by consistently mining an average of 51/100 blocks for *every* 100-block window." https://xcancel.com/kayabaNerve/status/1955227616195092923

"A 6 re-org does not mean a '51% attack' was successful. In that case, we'd see unbounded-depth re-orgs/no blocks mined by any other mining pool (assuming the adversary censors other mining pools, as this one does). It does mean an adversary with a high amount of hash got lucky." https://xcancel.com/kayabaNerve/status/1955173552363016434

"Qubic never actually hit 51% btw. Don't fall for it. However they do have a large enough hashrate to perform multi-block re-orgs with their selfish mining strategy. They disabled API hashrate reporting so that they could lie about it. Keep mining and ignore the noise." https://xcancel.com/tuxpizza/status/1955191610410401816
