I am sceptical of most use cases of block chain outside payments witnessing in some limited trading schemes. There are 2 inter-related problems.
- block chain is a very inefficient solution to a problem that largely does not exist in healthcare: untamperable evidence that something happened, in the context of not having any trustable governor. In almost all cases, we actually want to be able to tamper with the record - except the audit trail. And/or suppress data from being visible except to a few authorised parties. For the audit trail, the average institution generates more data per day than block chain presently holds - we are talking vast amounts of data - the inefficiency is considerable - full block chain requires some benefit to the miners - and in any volume of data, the price is considerable (e.g. blockchain consumes more power than nigeria, I read this week); that is not evident in any scheme I've seen, but schemes that have restricted mining loads require restricted attack surfaces, and I don't believe that there's a sweet spot there in healthcare There are some interesting use cases around selective sharing data for research using active blockchains (e.g. ethereum) but by and large these seem outside the scope of records and EHRs to me Grahame On Mon, Nov 13, 2017 at 11:24 PM, Bert Verhees <[email protected]> wrote: > On 13-11-17 13:06, GF wrote: > >> What problem is BlockChain solving, that deployed technologies can not >> solve? >> > > Read the document I linked to in my previous message, you can read dutch. > > >> Gerard Freriks >> +31 620347088 >> [email protected] >> >> On 13 Nov 2017, at 12:46, Bert Verhees <[email protected]> wrote: >>> >>> How are the plans about blockchain for OpenEhr?
