Blockchain Security

"At its highest level, blockchain is a trust layer."

In nine words, Kaleido Insights founding partner Jessica Groopman succinctly summarized the gist of CDX Academy's "Blockchain Brand Innovation Summit" on May 11 during her opening remarks.

The summit itself brought together representatives from blockchain startups and incumbent institutions to debate and discuss different use cases for the technology, noting both its advantages and its flaws.

According to various panels, the obvious use for blockchain is in data storage, whether in healthcare or in other private, consumer data. The overreach of many centralized institutions as it relates to personal data, in particular, has made headlines recently, perhaps the most notable being third-party application's collection of Facebook users' private information.

blockchain does not need to store data (health records)

a block can just contain just a hash for a health record and not the patient data itself.
and separately the health record has all the patient data in a standard database. but requires a hash to be confirmed into a blockchain before the patient data in a separate database is classed as verified.


for instance. imagine side chains imagine there were 2000 bank branches with their own chains/databases for their own local customers of the town that bank branch represents
but then there is a master blockchain/DLT that just holds the hashes(block header ID) of the 2000 bank branches most up to date instance


the other thing is the over use of "blockchain"
blockchain should be used for open public use (eg internet)
distributed ledger tech(DLT) should be used for closed privat use (eg intranet)

these days i have seen many business try to say their private security models will be blockchain. and then also say the public networks are DLT
