News outlets are champions in exaggerating potential effects of abuse. Miners today have more incentive to NOT abuse any sort of bug than to actually abuse it.

The main reason client upgrades happen so slow is because of how distributed the network of nodes is This isn't BCash where Roger and Bitmain on their own can upgrade their entire network effortlessly at once.

What I am (happily) surprised about is the actual number of nodes, which shows that there is a lot of confidence to run such an intensive application. I am pretty certain that all nodes of every single altcoin combined don't even account for 100,000 total nodes.

It's not an exaggeration to say what would happen if that bug was successfully abused, exaggeration would be saying that Bitcoin is now broken because of that bug, which is of course not the case. I've read the whole article and I don't see any bad journalism, aside from EOS shilling in the end - in fact this is a much better article than the crap that comes from coinidol that gets posted on this board every day. This article simply provided a summary for Luke Dashjr's report and explained the deal with listening and non-listening nodes, there's no FUD or doom in there.

ok

  • every node on the network receives their blocks through the listening nodes
  • more than 50% of listening nodes have been running Bitcoin Core 16.3+ for a while now

so the bug is not exploitable. end of (non) story

Miners have had enough time to exploit the bug but never had the incentive to do so. You can pull off an exploit once, but the consequences of that are that you trash your reputation as miner, and people will shift their hashrate to other pools, and then not to mention the effect on the market itself.

It's also an exaggeration at this point in time because the actual threat that was a threat no longer is. News outlets don't want to include that part because it makes the article itself pretty useless. The average person sees 60% as in the majority is still vulnerable, while the reality is much different. That generates clicks.

Lukedashjr often posts things without actually nuancing them. Roll Eyes

no, you can't

this exploit was only possible until about a week after 0.16.3 was released, after which more than 50% of listening nodes were running patched up nodes.

If a miner tried to exploit this bug now, they would fork the blockchain, and they'd be on the inflation fork. That's the reason no-one's tried, nothing to do with reputation, it's about money.

I was talking more in the moment itself. As miner you can only pull this off once.

Reputation is a big deal for large miners because most of their hashrate isn't their own. I'm sure that you clearly remember what happened when GHashIO started ignoring people's concerns and grew bigger regardless of what the sentiment was back then. They are gone. It's not related to a bug or whatnot, but seeing one single miners trigger all red flags means the end of your operation. Period.
