Bitcoin Transaction Malleability and MtGox The transaction
malleability problem is real and should be considered when im-
plementing Bitcoin clients. However, while MtGox claimed to have
lost 850,000 bitcoins due to malleability attacks, we merely
observed a total of 302,000 bit- coins ever being involved in
malleability attacks. Of these, only 1,811 bitcoins were in attacks
before MtGox stopped users from withdrawing bitcoins. Even more,
78.64% of these attacks were ineective. As such, barely 386
bitcoins could have been stolen using malleability attacks from
MtGox or from other businesses. Bitcoin Transaction Malleability
