Over a dozen blocks are being reorgd & up to 3 versions of the chain being mined simultaneously across pools.

CoinMetrics also tweeted later on the attack saying its security monitoring tool FARUM noted a 14-block reorg of the Bitcoin SV network.
All of our FARUM nodes witnessed a deep reorg with a max depth of 14 blocks.
No further reorganization events have been witnessed, but there are still synchronization conflicts taking place on major mining pools. pic.twitter.com/aM6FoWOKke

The Association recommended that node operators invalidate the fraudulent chain that came into existence post the latest attack.
To invalidate the fraudulent chain, node operators should run the following command on their #BitcoinSV node:
bitcoin-cli invalidateblock 000000000000000003B67AEC95E9B5DA897EB5EBF3227D5A6A67835104367840

In June, Wright got a ruling in his favor in a case involving copyright infringement related to the original Bitcoin whitepaper authored by Satoshi Nakamoto, the presumed creator of the apex coin.
The court asked “Cøbra” the pseudonymous operator of Bitcoin.org to remove the whitepaper, to which Craig claimed to hold the copyright.
On Tuesday, Cøbra said on Twitter, “Imagine if a bank got robbed every few weeks. Would you trust their security deposit boxes with your valuables?”
