If the goal is transparency and the affliction of the powerful to comfort the afflicted, then it seems that a publicly distributed and inspectable ledger would have a role to play.

If the goal is privacy and anonymity, then efficiently managing large numbers of entries may be counterproductive and large latency and search inefficiency becomes a feature.

Just chumming the waters….

Though "Blockchain" is in the title of this discussion group, it need not be in all of the solutions.  "Blockchains" have large privacy and data security challenges built into maintaining consensus on the state of the ledger (database).  Most real life situations have available a range of alternative means of validating the state of the ledger.  For instance, a regulator.

So, we might view it as a bug, rather than a feature, if a "smart contract" solution requires execution on a blockchain.  

Organizations and humans will want to be able to efficiently manage large numbers of ledger entries, in efficient databases (SQL, graph, IPFS), not blockchains.  They will need to be able to run the smart contracts on those other platforms.  

Data replication should be minimized, and temporary to the extent possible.  This will, I think, also be required by GDPR.

The necessary point of agreement, the waist of the Zittrain hourglass, is very small - a format for ledger entries.  CommonAccord asserts (I assert on its behalf) that the key to this is ... key/values, a way of resolving references, and inheritance.  For good reasons, JSON is a likely to be the most common "punctuation" (Eve's word) for exchange of ledger entries.  Our current rendering engine uses plain text and carriage returns.  That is the lightest "punctuation" and may be the best for collaboration on big texts, notably for collaboration among lawyers and regulators on Github.  It closely parallels the presentation of software source code.  But this barely matters.  What matters is a common approach to linking and inheritance.

Domenico;

As soon as the use case makes Alice's role that of a "Citizen" a whole raft of non-technical issues arise that should be addressed. How do you implement privacy protection into the architecture to avoid abuse by authoritarian regimes? If I think of all the cases where I'm asked to present government issued ID as proof of identity, and then ask, "Would it be a good thing if there was an permanent audit trail available to the government (any state agency) of all those interactions?"

I would restate your problem definition to see if we can design a wide identity ecosystem use case for managing citizen identities that enables (or better, only works if) citizens control their own identities. 

(PS, see my signature block below, apropos of this issue)

Hi all,

maybe, you already know blockstack id technology for identity services, at blockstack.org 

I think it’s quite useful for investigation and for defining use cases.

I was wondering whether we can provide a wide identity ecosystem use case for managing citizen identities.

Consider the following high level use case:

- The Citizen is identified by a Blockchain-ready Registry. 
- The Citizen requests to register with the Registry through a specific mobile app, which provides the necessary cryptographic key pairs with which the request is signed.
- The Registry includes the request in the blockchain which is distributed among the nodes, as smart contract.
- The mobile app and the cryptographic keys are now able to provides strong authentication mechanisms for citizen online access.

Citizen Identity can be enriched through the blockchain nodes (special nodes) interactions which provide attribute/profile attestation.

I hope it’s useful for further discussions.

Thanks
Domenico
