26 November 2018 Statement on Bitcoin Cash and Bitcoin SV
On the 15th of November, 2018, the Bitcoin Cash network was attacked in an attempted 51% attack. The attack failed. The attackers, who call their blockchain Bitcoin SV, have split into a distinct blockchain from Bitcoin Cash.
As of Monday, 26 November 2018, Bitcoin Cash tips have been re-enabled.
Bitcoin Cash tips which were scheduled to expire between 15 November and 26 November have had their expiration dates extended to 27 December. If you wish, you may reprint these tips to show the new expiration date. Tips will be paid out with post-split BCH.
We will be contacting donors in the next few days with instructions on how to claim Bitcoin SV refunds.
13 November 2018 Statement on the Planned Attack on Bitcoin Cash
On the 15th of November, 2018, the Bitcoin Cash network is likely to experience significant disruption. A hostile actor, claiming to have the true vision of Satoshi, has announced that he plans to attack the network starting on that date.
To protect the cryptocurrency held in trust here, we plan to take the following actions:
- At 12:00:01 UTC on 14 November, all Bitcoin Cash tips which expire on that day will be refunded as normal.
- After these tips are refunded, all Bitcoin Cash activity will be suspended indefinitely. It will not be possible to create new tips or redeem tips.
- Tip expiration for Bitcoin Cash tips scheduled to expire during or soon after this attack will be extended. The expiration will be reset to 30 days after the end of the attack for all BCH tips which expire before that date, whenever it happens to be.
Due to the nature of the attack, it is not expected that there will be two separate chains at the end of the attack. Rather, only one chain is expected to exist, with the other rejected by the network. Thus we do not expect to be able to redeem or refund tips onto two distinct chains, as there is expected to be only one chain. In the unlikely event that the attack does result in two distinct chains, we will make a further announcement about how to claim funds on the alternate chain.
