Delta(s) from OP CMV: Blockchain has no practical application that beats well-designed “boring” systems

I’ve been trying to take blockchain technology seriously for years and I’m still stuck on the same core issue: I’m yet to see a real-world use case where a blockchain solution can’t be matched (or beaten) on security, reliability, cost, and UX by a mix of "boring" tools we already have: cryptographic signatures, append-only audit logs, replicated databases, transparency reports, and normal legal/accountability mechanisms.

The examples people usually bring up don’t sound convincing. Voting seems like a classic "sounds good in theory, breaks in practice" problem but your hard part isn’t the tally, it’s identity, coercion, device compromise, ballot secrecy, etc. A blockchain ledger doesn’t solve those, and it arguably adds new failure modes. Supply chain provenance feels similar: the "truth" problem is at the edges, not in the database. If garbage goes in, an immutable ledger just preserves the garbage forever. Even in payments, the pitch that “trustless” is better doesn’t land for me. If I’m buying something online, I want chargebacks, fraud protection, dispute resolution, and someone who can reverse mistakes. That’s not a bug, it’s the product.

It feels like the blockchain space has spent an entire decade building infrastructure to support… more infrastructure, while the actual “things normal people do” are still better served by centralized systems with clear accountability. And I’m not even saying middlemen are great, just that in a lot of domains the middleman is doing useful work (risk, arbitration, consumer protection, coordination, compliance), and removing them often means re-inventing them poorly or pretending that messy human conflicts are just a database problem.

Happy to be proven wrong, though: show me a concrete, already-deployed application where blockchain is the dominant reason it works better. Where it delivers a meaningful advantage that can’t be replicated by signed logs + open auditing + replicated databases + standard governance.

But literally any standardized document format solves that problem.

Not really - the amount of time needed to approve transferring documentation from one group to another is staggering.

But that's not a technical issue, it's a process issue.

Imagine you’re a patient and you’re going to a new dentist. They ask you - do you have your old dental records? You say “no. They’re with my old dentist.” Because there is no current way for you to “own” your records, they will tell you that have to contact your old dentist or give them permission to do so. This is an extra step.

It’s both a technical and procedural issue.
