I was a bit surprised to see Blockchain is not part of the 2018 CISSP CBK. I would expect that it be included with the section 3.9 Cryptography as part of non-repudiation. Perhaps not enough people mentioned working in blockchain in the work force surveys leading to the 2018 update.
Do you expect that over the next 3 years blockchain will grow in prominence ?
Do you think GDPR will kill blockchain? There are a few good articles out there that explain this issue. Here's one by Tripwire https://www.tripwire.com/state-of-security/security-data-protection/blockchain-gdpr/
I look forward to hearing your views!
There has been some promising research in the use of blockchain technologies in healthcare and stock transfers but down here in the trenches I don't see it in use yet, just theory level at this point.
If you are currently working with this technology on a regular basis I am sure others would also like to hear your thoughts on the subject. For now, I don't foresee this technology going mainstream anytime soon, though I may be very well wrong on this point.
Yes, I work in the healthcare technology practice of security.
Having studied blockchain in some depth, particularly the crypto and database design aspects, I continue to see problems without good solutions. It is very much like the interest over quantum cryptography (which is not cryptography, but merely key exchange): it is an intriguing and elegant theory, which falls apart upon implementation.
I am increasingly agreeing with the opinion expressed on a T-shirt at a recent conference: "Blockchain is not the answer."
And, sorry, GDPR will not kill blockchain. Blockchain is a technology. GDPR is really just a checklist type of security framework. (With huge fines for non-compliance, yes, but nothing more than that.)
