after fork change algo yesterday why diff aka nethash still so high where is the source come from ? i see global nethash about 16Mhs and then every pool not more than 1Mhs who is the robber ?
We just experienced a 23 block chain reorganization, a potential double spend attack on our network - everybody with buy orders on exchanges please pull out now until the exchanges respond with an audit of their databases!
Two good reasons why nobody should support the Nicehash botnet for hire, run by a known convicted criminal. Anyone who is pro-decentralisation and therefore anti-ASIC, should also be against the centralised Nicehash botnet where every criminal can hire for a short time and therefore basically at zero cost a massive botnet to attack and double-spend, i.e. defraud the community (exchanges, merchants, users). No, these criminals would not be able to buy 25,000 GPUs and set up a huge farm in order to make a double-spend attempt, but at Nicehash they get this for a few hundred bucks. Let's not forget, the DAA upgrading too started as a result of Nicehash instamining attacks in the early phase of the chain (kudos to that mysterious "user" on slack who kept pushing until the problem was finally tackled ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) ) Say no to nicehash as you say no to vertical video ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) Only the dumbest people use the nicehash "miner", i.e. rent out their PCs to a criminal, ( and vertical video...) For reference: Former Botmaster, ‘Darkode’ Founder is CTO of Hacked Bitcoin Mining Firm ‘NiceHash’

What's up with all those tx which don't clear and hang for hours in the mempool? I saw that last one already yesterday sitting there, when it was the only one stuck. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FCq9OIig.jpg&t=665&c=NXtTqZRYLdz44w) They are not too large in size, they seem to have enough fees. What's wrong with them? Are those from today which are 6h old made from inputs which have vanished after the re-org? Shouldn't they simply drop out of the mempool in that case? EDIT: Those two tx which were stuck for 2h on the screenshot have cleared meanwhile, both in block 170536. The other four are now at nearly 9h of age and still stuck. Not my tx, just observing. EDIT: Another thing. Are those time stamps (deltas) from 170561 to 170576 fake or do we just witness a huge instamining/double-spending attempt? EDIT: What is going on with the official explorer at https://www.msrchain.net/Whenever I hit F5 I see how the "age" of the last mined blocks (always the same) is decreasing! See a sequence of screenshots at https://imgur.com/a/vuiFIGVYou will also notice on that sequence of four screenshots, how from 3 to 4 one tx drops out of the mempool without entering a block. Its hash starts with 2007884... I think the chain is being attacked again by an idiot renting the nicehash botnet. Because the blocks were flying and difficulty has shot up. I guess it is safer to refrain from depositing and withdrawing coins at the moment. EDIT: If the time stamps on the official explorer are not totally faux, then there was a POW attack from 170561 to 170581 and possibly to 170605 and then another one from 170610 to 170626. Another attack was from 170523 to 170553 (and some pools got their blocks orphaned in that range, so I hope there was not another re-org).

Can you say a bit more about what's going on here? Someone implies this is coming from Nicehash -- is that true? I see on Twitter you recommend increasing tx confirmation to 60 blocks? Are we out of the woods yet? Thanks.

It's a shame. It was looking promising.
Off to another coin whilst Masari sorts it's shit out.

Unfortunately this is definitely looking like a timestamp attack. The sum nethash of all the pools (the real miners) is under 2Mh/s while we're seeing spikes northwards of 27Mh/s in the network. That's an extremely unhealthy ratio. Some malicious entity is virtually stealing most of the blocks.

I thought the DAA was meant to protect from this? I’ve pulled from mining because it’s completely broken, blocks are just orphaning across all pools. Bit of a disaster.

Its just maturing of coin with low hashrate and malicious people who want this coin dead. IMHO ofkors

The DAA is enforcing the planned emission of coins via the difficulty, making sure that nobody could instamine and create temporarily a huge "inflation". The DAA can not protect against a 51% attack. We have a 51% attack, not (only) a timestamp attack. Someone had to find those blocks before he could submit them with a faux timestamp, hence 51% attack. This attack maybe also explains the extremely irrational selling behavior in the days prior to the fork. The person or entity which dumped all those coins (I guess a ASIC miner) was obviously in a hurry to cash out. It's entirely possible the same person/entity is now behind the attack, having a huge war chest to rent the nicehash botnet and rape the chain.

Yes, I think most of the pools are ok now.

Definitely this is some of the long term solutions for the attacks.

The source from which existing things derive their existence is also that to which they return at their destruction.

Will the online wallet masari.network be okay to use after the fork? I got the key phrase. I should be fine, right?
