| New ASICs are shipping to mine Equihash, and there have been "51% Attacks" using at least four coins in the past month (Monacoin, Verge, Bitcoin Gold, ZenCash). Bitcoin Gold will be among the first major coins to introduce a different PoW algorithm to secure our network against these threats.
We wanted to share details about our Network Upgrade (which is nearing readiness), about the new PoW algorithm, and about some of the other work we've been doing to help protect you and all our partners in the space. |
