if it's opaque to analysis, what's the point in using a blockchain? why not just a central database?
I would have thought this to be obvious, but these chains, while anonymous still have the following attributes:
- decentralized
- permissionless
- does not rely on third-party trust
A central database has none of these attributes.I was under the impression that nearly the entire thing is based on some form of consensus. Consensus is necessarily by third parties. So if the consensus drives decisions on what gets accepted and what does not, is that not a permission? If there is a single dominant consensus, is that not centralized?
further, none of this is "obvious"
