Manu, this sounds a really interesting use case. The Corporate identifiers is a huge topic, since it touches on a vast number of additional use cases, like representation rights, founding documents, share ownership, etc. We have just released a PoC project in Finland, where we created a shared founding process (using Corda) to create a Ltd Company denoted by a DID (Indy) and attested by verifiable claims from the registry official and banks. We tested creation of representation rights, API delegated access credentials and DID-based document signing, among other things. Press release: https://www.tieto.com/news/blockchain-technologies-enable-new-businesses-to-have-a-fully-digital-identity Do you think these use cases should be separate, or should we collaborate on this?

Name ---- Decentralized Corporate Identifiers Background ---------- There are many types of identifiers that corporations use today including tax identification numbers (e.g. 238-42-3893), Legal Entity Identifiers (e.g. 5493000IBP32UQZ0KL24), Data Universal Numbering System identifiers (aka. DUNS Number) (e.g. 150483782), and many more that communicate the unique identity of an organization. None of these numbers enable an organization to self-issue an identifier or to use the number to cryptographically authenticate or digitally sign agreements. A great number of business to business and business to customer transactions could be executed more quickly and with greater assurance of the validity of the transaction if a mechanism to self-issue cryptographic identifiers were created. Description ----------- A North American government would like to ensure that the supply chain that feeds electronic products into the country is secure. As a result, a new method of submitting digital documentation to Customs is enabled that requires that all documentation is provided as machine-readable digitally signed data. Digitally signed documentation is collected at each stage of the manufacturing, packaging, and shipping process. This documentation is then submitted to Customs upon the products entry into the country where all digital signatures are verified on the documentation. Some aspects of the signed documentation, such as firmware hashes and checksums, are then used by Customs and downstream customers to verify that the products have not been tampered with after leaving the manufacturing facility. Decentralized Identifiers are chosen in order to ensure 1) low management overhead for the government, 2) self-management of identifiers and cryptographic key material, and 3) a competitive marketplace. Sticky Wicket ------------- The requirement of downstream customers to use the same documentation and digital signature mechanisms that were provided to Customs is the sticky wicket in this scenario. Governments often create ad-hoc solutions for their import solutions, which make securing the global supply chain difficult as each government has their own method of securing the supply chain and identifying corporations that downstream customers need to integrate with. If you are a global company, that means integrating with many supply chain systems (each with different capabilities). As such, any securing of the supply chain with downstream customers must then depend on the country-specific corporate identification and PKI solution, which leads to ad-hoc solutions that drive up the cost of doing business across borders. A supply chain identifier solution that is simple, self-administered, built on global standards, is flexible in the cryptographic mechanisms used to authenticate, and can be used by governments and downstream customers with little to no modification to the regional government or corporate systems does not exist today. Distinction ----------- Many Decentralized Identifier use cases focus on Self-Sovereign Identity and individuals. This use case focuses on organizations and their departments as entities that would also benefit from Decentralized Identifiers. -- manu [1]https://lists.w3.org/Archives/Public/public-credentials/2018May/0015.html -- Manu Sporny (skype: msporny, twitter: manusporny, G+: +Manu Sporny) Founder/CEO - Digital Bazaar, Inc. blog: Veres One Decentralized Identifier Blockchain Launches https://tinyurl.com/veres-one-launches
