Re: Bah.
Sovrin looks interesting. I think IoT will be looking for sources of immutabie data, and these devices on their own won't be able to do that. This is where blockchain platforms like these are expected to come in and offer value.

Re: Bah.
To answer your question about "unification": what the Sovrin ledger provides for your "army of identities" (since you can have as many as you want) is a public key discovery service. Each contextual identity (i.e., each DID—decentralized identifier) has an associated JSON file called a DDO (DID descriptor object). That's how you find the current public key for doing encrypted communications with the identity owner.

For the full details, see the DID Implementer's Draft 01 spec (which can work with any suitable distributed ledger, including Bitcoin and Ethereum, not just Sovrin).

Hope this helps.

Re: Bah.
I was able to read between the lines to understand it's not the same blockchain as Bitcoin, but we've seen that even distributed ledgers aren't hackproof.

That said, I see what you are saying (the lede through me off).  But at the same time, the concept of "identity" implies unification.  I don't particularly want my smart home devices and other online accounts or devices to be linked.  Sure, I have "control," and can decide to have more than one identity, but then why am I using a ledger to begin with in that case?  What's my get?  (Asking in earnest -- not rhetorically.)

Re: Bah.
@Joe Stanganelli Self-sovereign identity works exactly the opposite of what you said. No one "assigns" you an identity. You generate your own and "assign" them to others when you decide to have a relationship with them. You can have as many anonymous or pseudonymous identities as you need.

Even though people call it "blockchain for identity", Sovrin is a distributed ledger, and has no connection with the Bitcoin blockchain. It's designed from the ground up for privacy-respecting self-sovereign identity.

Re: Bah.
What the article didn't convey, is the fact that Sovrin was designed from the ground up for someone to act anonymously, or pseudonymously with unlimited identities.

There is no registry that someone can look up someone else's identity, it simply doesn't exist, the only way someone can find and decrypt something is if they've been given explicit permission by the holder of the associated private key to do so. And even then it's a onesy-twosey relationship, no way to open some door to a pile of your information.

In fact, it's an ideal way to manage your Joe Stanganelli (pseudonymous) identity in the same place that you manage your true legal identity, and no one has any way to correlate the two identities when you use them, because Sovrin uses "pairwise" identifiers under the hood for every relationship.

So if you're focused on privacy you should appreciate Sovrin, it offers the most advanced privacy enhancing technologies currently in existence.

Bah.
Blockchain-encrypted or not, I'm vehemently opposed to this kind of thing for the very reason I'm opposed to NSTIC.  It fundamentally flies in the face of true privacy to "assign" identities--and I tend to think that just because the word "Blockchain" is attached that that doesn't mean all the Blockchain/Bitcoin fanboys and fangirls will go along with it.

Sure, I'm "Joe Stanganelli" here, but I'd prefer to keep my right to be pseudonymous/anonymous elsewhere.
