So let's say you do set up a meeting with Experian, TransUnion and EquiFax and now need to prepare a slide deck to convince them to migrate their existing tech (let's say a master MySQL with a bunch of slaves, shared write access for trusted entities) to blockchain.
What's your selling point? Lower costs when deployed at the datacenter? Decreased hardware costs? Greatly increased TPS? Faster lookups? Easier to build applications on top compared to the existing stack?
In corporate IT the mighty dollar rules the day. MySQL and Postgres had hostile incumbents, Linux and open source in general had hostile incumbents, commodity hardware for the data center had hostile incumbents, AWS (or Google Cloud) had hostile incumbents, Splunk, Cloudera, SalesForce and any other SAAS company had plenty of hostile incumbents.
Yet end of the day they were able to show cost savings, and either sell it at the CTO/CIO level to existing companies or enable startups with much more rigid cost base, which in big companies quickly got the CIO's attention.
There's nothing particular about blockchain tech that I can see that introduces a major game changer on the cost savings front. Launch two identical startups today, one on top of blockchain, another on top of MySQL. Will the first one have lower operating costs 1, 5, 10, 20 years down the road?
