Monero May Be Under Attack, Developers Deny

It’s unclear however at this stage what is going on, if anything, but a number of Monero users paint a picture of a network under attack
08 May 2018   1648

Monero could be attacked. This could be possible due to a significant decrease in the computing power of the network, which occurred against the backdrop of hardfork to confront ASIC-miners last month. This is reported by TrustNodes.

There was one fork that reorganized by an astonishing 21 blocks. That means the eventually-thrown-away branch was the longest one for 21 blocks before the “other” branch (which eventually became the winner) overtook it. A 21-block branch is enough to double-spend against basically anybody.

Monero developer replied to the user.

His reorg is dated yesterday, but it’s a section of blocks from 2.6 days ago, so DEFINITELY a reorg during catch up. Nobody else has seen anything besides a reorg of a single block or two, and http://xmr.to has been down for unrelated reasons. Much ado about nothing.

At least 2 messages on the implementation of double-spend attacks appeared on the network.

2 days ago I send first out transaction, but something went wrong and above 24 hours balance was 0. XMR returned, but now I cannot send them.

 Monero Double Spend Issue
Monero Double Spend Issue

I am struggling to send my balance of XMR to another wallet. I have tried both GUI and CLI and everytime I get an error that suggests I am trying to double spend.

Developer said these complaints of double spends are “probably because they’re using a remote node or something weird.”

Currently, it's not clear what exactly is happening, but some Monero users continue to claim that the network was attacked.

A lot of weird stuff happened on mainnet in the past 48h… My public node stopped syncing and got corrupted tx-pool. Up to 10 of our pool leaf nodes stopped syncing several times as well.

Another user reported on miners issues.

My miners and node have been DDoS’d like crazy the past couple weeks… I believe Dwarfpool has been affected, deeply, by this whole shabang. Haven’t gotten a payout in a couple days and hashrate dropped for ‘no reason.

At present, the information remains unconfirmed. The probability is that the problem, if it really exists, can be caused by configuration problems for individual miners or even by a bug in the fork code that took place last month.

Monero developer Spagni, in turn, claims that he does not observe deep reorganizations of the Monero blockchain, and in response to a request from Trustnodes, he wrote that he was ready to confirm the absence of double spend issue in the cryptocurrency network.

OKEx Korea to Delist Anonymous Coins Due to FATF

Monero, ZCash, DASH, Horizen and Super Bitcoin won't be supported starting from 10th of October

The Korean division of the OKEx cryptocurrency exchange has announced the delisting of five anonymous coins, as they violate FATF standards.

On October 10, the site will stop supporting Monero, ZCash, DASH, Horizen and Super Bitcoin.

Recall that the FATF obliged the bitcoin exchange and other cryptocurrency service providers (VASPs) to follow AML and CFT procedures similar to traditional financial companies.

VASPs must exchange the personal data of participants in transactions and information about the balance of their wallets.

OKEx Korea emphasized that anonymous cryptocurrencies will not allow the exchange to comply with these rules.
