It’s almost less that there’s a old stamp in there and more that the same tight configuration of rushed miner rewards fall around it in such a similar configuration so often, and I’m not even looking for it. I just notice it in the most recent transactions when I check zchain to see what the difficulty is.
4 rewards in 60ish seconds, one well out of time sync. I gather the rewards wouldn’t roll out like clockwork regardless of timestamp, but how likely is this particular pattern to keep repeating so often that I keep spotting it off-handedly at the top of recent tx?
I know this could just be noise, but I may keep posting it from time to time in hopes of inspiring someone smarter and more heavily vested in Zcash to take a closer look, because it sure smells like a signal. A smart attacker may well avoid abusing the attack to avoid detection, but if I’ve spotted it this many times without looking, what would a smart search for that pattern unveil?
Edit: just switched over to close zchain, and noticed hashrate down below 10million sol/s, right before I took that screenshot, there was 20+million sol/s. Assuming that’s measuring accurately, it would appear all this is happening around massive bounces in hashrate as well. Something else that smells to me.
