No. The blockchain can do 2nd factor. I am developing a wallet for that. You need one or a number of third parties for cosigning that do one time passcodes and special software that can send these partially signed transactions to said parties. The wallet needs to be manipulated by the owner key to weaken the authority 9/10 power and then give 1/10 power to the others. Once set up, The third parties cannot misuse the power because they do not have enough authority. A hacker with your active key cannot misuse without the 2fa.
