Crisis Strategy Draft Situation
For several weeks MtGox customers have been affected by bitcoin withdrawal issues that compounded on themselves. Publicly, MtGox declared that “transaction malleability” caused the system to be subject to theft, and that something needed to be done by the core devs to fix it. Gox’s own workaround solution was criticized, and eventually a fix was provided by Blockchain.info. The truth, it turns out, is that the damage had already been done.
At this point 744,408 BTC are missing due to malleability-related theft which went unnoticed for several years.
The cold storage has been wiped out due to a leak in the hot wallet.
