In the healthcare related blockchain ideas or prototype implementations I have heard about so far something different than proof of work is used, for example proof of authority. That has other drawbacks and challenges, but it does not suffer from the same power consumption problems.
Also any public healthcare related blockchain has interesting privacy issues that will need to be solved.

Bitcoin is since a few weeks prohibited in China but it seems hard to kill. But still, I don't think the use of blockchain in healthcare can be compared to the use of blockchain in currency, because, bitcoins is about getting rich by creating as many as possible, while in healthcare they exist to facilitate processes, and the number of processes create the demand, not the wish to get rich. Another thing which came to mind, electricity is expensive because it needs to be created near the place where it is going to be used, or it needs to be transported. But blockchains for any purpose can be created on any place on earth, also on places where energy is almost for free. For example, windmills on top of the Himalaya, or solar cells in the middle of the Sahara. Just transport the bitcoins, no need to pollute the world very much. _______________________________________________ openEHR-technical mailing list [email protected]<mailto:[email protected]> http://lists.openehr.org/mailman/listinfo/openehr-technical_lists.openehr.org _______________________________________________ openEHR-technical mailing list [email protected] http://lists.openehr.org/mailman/listinfo/openehr-technical_lists.openehr.org
