  Inheritance is the fundamental building block of civilization. This is the
addition of wealth, knowledge and properties over time that produce the society
in which we are living. Every generation does not have to start from zero and
can capitalize on the efforts of previous generations. Blockchain based assets
are very efficiently and securely transferred between living entities. Yet the
actual way to make heirs inherit crypto-assets is seldom discussed. It appears
that the problems linked with the inheritance of crypto-assets raise a lot of
technical, societal and legal issues. Part of those issues have to be tackled
with at the level of the blockchain infrastructure itself. The aim of this
paper is to open a research field, and to discuss some ideas, with regards to
this overlooked issue. Inheritance is neither a peripheral question nor one
that can be dodged. It comes with its own set of challenges that have to be met
if blockchain based finance, and asset management, is to be taken seriously.
