As mentioned above, this method of inheritance for digital assets is every bit necessary. As no one can truly hold onto your private keys or passwords, which house your digital assets, they can't attempt to act in a fraudulent matter.  Due to the involvement of blockchain, though the transactions would be traceable, the identify of whom moved them would be more difficult to obtain.  Thus, this brings along the concern in using traditional inheritance vault-like solutions to store digital assets.   At the moment, there are no inheritance solutions within the blockchain digital-asset space. We are changing that.
