Bitcoin Gold Emergency Update


On July 10th, the BTG Team has detected an extremely long attack against the BTG network, specifically a chain of over 1300 blocks that have been mined since July 1st 2020.

The Bitcoin Gold Team was quick to alert pools and exchanges to take measures immediately and many of them closed their wallets over a week ago.

BTG version 0.17.2 was supplied to replace the previous version, and it included a checkpoint at block 640650, hash 000000059ec8884fa4fbbdbe46c09cfb4ecba281dfa2351a05084e817c1200ae from July 2nd at 2am UTC.

According to the BTG team "With this block checkpointed, the attacker’s chain could not take over, but this information was not public, and the attacker continued to mine. The attacker mined their secret chain for nearly 10 days, renting power from NiceHash to do so. Today, on July 10, the attacker released over 1300 blocks. Because those attacking blocks are anchored at a block mined on July 1st (before the checkpoint), the honest pools and exchanges who are running the updated code automatically rejected the attacker’s chain."

In order to stay on the honest chain BTG Core full nodes have been updated to version 0.17.2 in BetterHash. This way we made sure that mining in was not interrupted or affected in any way. The update is made in the background so there is no need for you to install anything.
