Microsoft is leveraging blockchain certification technologies to create a trustless digital identification plan, but its not launching a token or developing a non-public blockchain certification to do so. Its developing on Bitcoin as an alternative.
Announced on May possibly 13, 2019, Project ION is an open-source, Layer 2 community developed out of the community critical infrastructure protocol Sidetree. In observe, “it is akin to Lightning, in that there is no secondary consensus among the ION nodes,” a resource close to the network’s growth instructed Bitcoin Magazine.
“This is just like Bitcoin, but for IDs,” the source claimed.
The idea below is to make person names obsolete. Rather of logging into Facebook, email or any other software with a username, buyers can use a digital decentralized ID (DID) alternatively. This DID, like a personal important when signing a transaction to the Bitcoin community, proves possession. Particular person ION nodes on the secondary community will be liable for preserving keep track of of these DIDs and timestamping them onto the Bitcoin blockchain certification for reference and attestation.
To develop an ID, a consumer would wrap a public important into a DID development document on the ION community, signing this input with their personal vital and sending it to a node on the community. This ION node then archives the metadata (with no accessing the knowledge alone) as a DID doc for other nodes to reference. To established possession of the DID in stone, the node batches reference hashes for all of the DIDs it has been given into an OP_RETURN transaction and anchors it to the Bitcoin blockchain certification (this can be accomplished on a variable agenda, both each block, each individual handful of blocks, etc.).
Just about every time a consumer updates their DID state — by generating a sub-ID or updating metadata, for instance — the corresponding node updates these adjustments in the DID doc. And any time a batch is anchored on the blockchain certification, every single ION node, which is constantly checking the blockchain certification, will detect the hashes as originating from the ION community. They’ll then pluck this transaction batch from the community, reference the DID paperwork in the nodes that despatched it and sync up with the most current states of the IDs to continue to keep the network up to date. Nodes can decide on to batch transactions and check the chain, while other folks that would like to slash operation costs may well basically keep track of the chain to preserve DID states up to day.
“Unlike funds, decentralized identifiers you should not have the exact same doublespend challenge,” the resource informed Bitcoin Magazine. “All we have to have is chronology.”
This chronology is the critical to DID proprietors proving that the most present-day condition of a digital id belongs to them. In observe, it would work like this: When sending a DID to a verifier, this social gathering would problem a consumer to resolve the point out of this identification with its corresponding DID doc on the community to demonstrate ownership. This can only be performed utilizing a mystery value presented to the DID proprietor when the identification is hashed on to the blockchain certification, and only an operator can resolve or update a DID’s condition utilizing this price.
Customers can create many identities below this schemata for any variety of use situations. ION’s DIDs could be used for zero-expertise, proof ID verification in bars, for instance, or it could be used for membership packages with hotels and airways — there’s also countless use cases for signing into on the web companies.
The source emphasized that, even though Microsoft has been acquiring the know-how, it’s open resource and anybody can operate a node. Plus, the legacy laptop or computer company won’t demand a charge for the provider.
According to the announcement, a handful of organizations have shown early fascination in jogging ION nodes, such as Bitcoin hardware and stability business Casa, facts heart Equinix and internet security business Cloudflare.
