Distributed Ledger Technology

In a blog: Block Chain's Occam Problem  Mckinsey expresses doubts on the usefulness of applications of Block Chain, in particular in financal industry, but also on the potential in many other application areas.The blog is a worthy reading.
Particularly also the conclusions that there can nevertheless be real potential in specific cases which would shift ownership on data from corporations to consumers. An excellent example seems to be private Block Chains that give members control (by having the crypto key on the ledger) over who can read the ledger, which could be an extending set of Identity or personal data, personal medical data etc.

Suggestions have been made already on ID management by Kim Cameron (see his "Laws of Identity on the Block Chain" of 27 May 2018 on his BLOG).

Similar ideas can be worked out for e-Portfolios, i.e. ledgers of personal education and experience badges.

The conclusion might indeed be as stated HERE that Block Chain becomes mature and ... boring.

At the EIC 2018, Kim Cameron, well-known from the 7 Laws of Identity, gives his vision on the potential of the GDPR in Europe and the development of a truly personal and multilateral Identity using Block Chain technology in a good way.

I am curious to your reactions and comments, to bring this important ideas further.

Today, blockchain is making its way in our daily life. Why not in healthcare? Healthcare providers are required to use electronic medical records buts sharing and re-using data is still a major issue. The blockchain technology has the ability to solve this problem while still keeping the data safe and secure. Data sharing can be based on so called smart contracts. Not only hospitals or doctors will benefit from these blockchain based applications. Companies in the health sector or researchers would be able to have a lot more data available from a wider audience an be able to run large-scale continuous longitudinal studies.

Everyone says the blockchain, the technology underpinning cryptocurrencies such as bitcoin, is going to change EVERYTHING. And yet, after years of tireless effort and billions of dollars invested, nobody has actually come up with a use for the blockchain—besides currency speculation and illegal transactions.

The objective of this discussion is to start a realistic analysis of the potential of Blockchain, its most beneficial application sectors, sectors where it would be difficult or not necessary to use etc.
