1 IRREVOCABLE AND AUTOMATED WISHES: WILLS ON BLOCKCHAIN
OK so this one is perhaps cheating slightly in the context of this blog, as it doesn’t really have anything to do with life extension or changes in the nature of mortality. However, given that we have seen how important a role legacies have played in the history of philanthropy, new ways of making them more available and more secure could be quite a big deal. And blockchain technology might provide one route to achieving this. The nature of a blockchain means that it can be used to create unique, immutable, time-stamped digital objects- and this could include a will (either a representation or hash of a paper will, or perhaps the will itself could be digitised). Some companies are already offering digital notarisation services which use blockchain in precisely this way for various kinds of legal documents.
You might ask what benefit using blockchain technology brings here, given that we already use third parties like solicitors to ensure that wills are trustworthy and secure. Well, for one thing, if we could do without solicitors the cost of making and updating a will would come down radically. This might then mean that far more people actually made a will rather than dying intestate, and this would increase the number of potential charitable legacy gifts. Furthermore, since blockchain-based wills would presumably be linked to some suitable digital ID (possibly a self-sovereign identity), and would be unique, the risk of multiple wills existing would be removed. Currently this can cause problems if different expressions of a donor’s wishes conflict with each other, and may lead to legal challenge.
The further benefit (or perhaps not, depending on your point of view) of wills being totally digitised on the blockchain (as opposed to just recording the existence of a paper document) is that the execution of their terms could be automated using smart contracts. These are self-executing computer protocols that perform set actions when specified trigger conditions are satisfied, as we've discussed in Block & Tackle. If smart contracts governing the distribution of assets according to the stipulations of a will were triggered when an individual died, this could do away with the need for complicated probate processes and would massively reduce the risk of a legacy being challenged.
Of course, there might be instances in which it is justifiable and important to challenge something in a will; which raises the question of how this would work in a context where we are relying on automated smart contracts. That isn’t a question I have the answer to, but the wider question of the legal status of smart contracts and the possible methods of recourse is a hot topic in legal theory right now (see, for instance the work of Harvard academic Primavera de Filippi), so presumably someone will come up with an answer.
