The "single source of truth" is what people have been calling the Corporate Data Warehouse since the dot com era. The realities of that approach -- centralized gatekeepers, too hard to keep everyone on the same schema, different subgroups need different variations on the schema, slowness to iterate since everyone needs to accept the smallest change, etc. -- all those realities is what has largely given up on that Single Source of Truth vision in favor of microservices or data lakes or choose your buzzword du jour.

Blockchain solves problems around auditability, but it doesn't really solve the practical difficulties around the original CDW vision. If you weren't able to make a centralized data store work with a sql database, you're not going to make it work with a distributed ledger.

Yeah I think that's fair. Certainly the hardest problem is the human one. I don't think blockchain is a silver bullet, just maybe it will help. I wouldn't dump millions of dollars into it or anything without some sort of pilot / proven model.

The solution is clear: blockchain microservices. Each microledger is localized to the team using it, allowing for individual ledgers to be reused and composed to facilitate organizational agility across the enterprise. Stakeholder mindshare will soar.

Had me at agility. Where do I invest?
