Blockstack, the control-your-data decentralized internet developer, has patented the method behind its single sign-on for each dapp system, Blockstack Auth.
The patent covers Blockstack’s technique for cryptographically signing into dapps with a single digital identification, with out requiring a 3rd get together to authenticate.
The system acquired USPTO’s approval on March 24 following an uncharacteristically quick eight month wait – most functions sit for about 32 months, in keeping with Erickson Law Group – and precisely three years after Blockstack’s 2019 launch of the Auth developer model.
Blockstack Auth goals to be Web 3.0’s one-password-to-rule-them-all, the patent paperwork present. It’s functionally just like Google and Facebook’s massively common one-click sign up processes that combine with a whole bunch of 1000’s of internet sites.
“But the underlying data flow is unlike” the massive tech’s OAuth protocol-reliant authentication companies, the patent description reads. Those third-party platforms take away consumer management by checking all data in opposition to their centralized servers. Serverless Blockstack Auth offers it again – by public key cryptography.
The course of works by exchanging JSON internet tokens between the dApp and the Blockstack browser. At sign up, the dApp generates an “ephemeral transit key” whose public portion it sends to the browser by an “authRequest” token. The browser in flip encrypts an “app-private key” with that public portion, which it then returns to the dApp in an “authResponse” token.
“This inventive realization obviates the need for a server-side identity provider,” the patent learn.
The patent’s language is at instances almost equivalent to Blockstack’s March 10, 2020, explainer article on Blockstack Auth, with verbatim subheadings and delicate variations attributable to the much less declarative voice with which candidates write submissions.
(For instance, the patent reads: “These tokens can be associated to JSON Web Tokens (JWT), they usually can be handed through URL question strings,” whereas the GitHub-editable March 10 explainer reads: “These tokens are JSON Web Tokens, they usually are handed through URL question strings.”)
Open supply, closed possession
The granting, Blockstack’s first, offers authorized clout to the Public Benefit Corporation’s common login instrument for the decentralized internet. But mental property rights deliver extra than simply authorized safety for the GitHub-loving Blockstack. It additionally prompts thorny questions on partitioning off concepts in an area, and by an organization that claims to place open-source on the “heart of everything we do.”
Two days after the patent’s issuance, Blockstack CEO Muneeb Ali opened a discussion board to debate “Blockstack PBC and patents.” CoinDesk was directed to the discussion board after reaching out to Blockstack for this story.
“We don’t want to be in a position where some other (large) company files a patent similar to the work PBC and the community is doing,” he wrote, pointing to the “recent surge” of massive tech corporations, resembling IBM, that file seemingly limitless reams of blockchain patent functions.
Ali wrote that Blockstack might file patents on its core workforce’s efforts – purely for “‘defensive’ reasons.” He left the door open on transferring patents to the impartial Stacks Foundation, procuring a defensive patent license, and even pledging to by no means provoke enforcement, as Tesla did in 2014.
The dialogue partially solutions questions raised in November 2019, when Twitter consumer @lightcoin, who had come throughout a separate Blockstack patent nonetheless ready for approval, known as on the agency to clarify its patent technique.
“Patents are like nuclear weapons: the best way to prevent them from being abused is to not create them in the first place,” @lightcoin stated.
At the time Ali stated Blockstack needed to stake its claims earlier than others did. He promised to “post about our future patent strategy” at a later date.
The debate is just like one crypto alternate Coinbase confronted. CEO Brian Armstrong stated up to now that he believes “patents should be abolished” however, like Blockstack, sees it as crucial to construct a portfolio for “defensive” causes.
