Proof Launches x401, the Open Protocol for Verifying the Authority Behind AI Agents

Published

on

Developed by Proof with contributors across payments, identity and AI, x401 lets any online service request proof of who authorized an agent’s actions. Live demos and a CLI are available today.

BOSTON, June 25, 2026 /PRNewswire-PRWeb/ — AI agents can now buy, sign, build, publish and move money. What they can’t carry is proof of who authorized the agent.

“AI is making actions and content effortless to generate. Trust will come from knowing who stands behind them. x401 gives every service a common way to ask for proof. Proof Digital ID gives people and organizations a high-assurance signed record of who authorized what.” – Pat Kinsel, CEO of Proof. “

Every company is racing to open its products to AI. The hard part isn’t getting agents to act; it’s trusting that a real person authorized them. Without that, a service has no safe way to let an agent through.

Today, Proof, the identity authorization company, launched x401, an open, issuer-neutral protocol that lets any website or API ask for and verify the identity behind agents.

With x401, a service can ask for the proof it requires: verified identity, age, membership, organizational affiliation, signing authority, proof of humanness, orf another trusted claim. The agent presents a compatible credential and authorization. The service verifies the issuer, claim, scope and action before proceeding.

Identity establishes who or what an agent represents. Authorization establishes what it is permitted to do. x401 binds the two into proof and unlocks agents’ ability to act on people’s behalf.

Open by design
x401 is an open protocol allowing any conforming issuer to deliver x401-compatible credentials. Any agent can present them. Every service determines which claims, issuers and levels of assurance it will accept.

That separation allows one protocol to support many forms of authority without forcing the internet to adopt a single identity provider or credential model.

x401 was developed by Proof with technical contributors from leading payments, identity and AI organizations. The public specification, implementation materials, and complete contributor list are available at x401.id.

Proof will submit x401 to the FIDO Alliance’s agentic authentication standards workgroup.

Built to complete the agent stack
x401 is designed to work with the protocols already emerging around agentic activity. In payments, x402 enables machines to make payments. AP2 and Verifiable Intent capture instructions and approvals in commerce. x401 now completes the missing link, when used together with these other protocols, agents can now pay, prove a person’s identity, and authorize specific actions.

“x402 is the open standard that lets agents pay for web resources over HTTP with pay-per-request settled in stablecoins, with no accounts or API keys. Through Circle Agent Stack and USDC, which settles nearly all x402 volumes, Circle has been one of its core contributors. x401, built with Proof, pairs that with identity: x402 answers how an agent pays, x401 answers who it is. Those are the first two questions any agentic transaction has to clear, and now each has an open standard. Circle is proud to be an early adopter and co-endorser of x401.” — Gagan Mac, VP Product, Circle

Proof’s digital identity: A high-assurance identity that can sign
Proof is launching the first live implementation that can satisfy an x401 challenge. Proof’s digital identity is one of the first inline implementations of OID4VC Issuance and Presentation, allowing people to verify their identity to an IAL2 standard and enroll just-in-time or instantly reauthenticate with a biometric. Developers simply request identity and Proof manages the complexity of who is enrolled vs not.

Using selective disclosure and zero-knowledge proofs, someone can prove that they are verified, their nationality, over a required age or authorized to represent an organization without exposing their complete identity record.

In addition to credential presentation, Proof’s platform is the first to support transaction signing, which produces verifiable records. The API supports signing authorizations like AP2 with Verifiable Intent and cryptographically binds a verified identity to any payment, transaction, or payload. Verifiable records prove who you are and what you’ve authorized, creating the evidence that every industry requires in the agentic era. U.S. law has recognized agreements made by electronic agents for decades. Proof provides what’s been missing: trustworthy proof of the person behind the transaction.

Proof’s digital identity is backed by Proof’s Kantara-certified NIST IAL2 identity service and WebTrust-audited certificate-authority infrastructure. As a Certificate Authority that pairs a publicly trusted, audited certificate hierarchy with IAL2-grade identity proofing, Proof’s digital identity is the only legal credential that can secure everything a person signs, does in person, does online, or delegates to an agent.

x401 works end-to-end today
The documentation for x401 is live today. The public specification, technical documentation, sample apps, and contributor list are available at x401.id.

Proof Digital ID documentation is available at dev.proof.com. Developers can connect Proof’s live x401 MCP server to Claude and ChatGPT to use x401 in real agent workflows. Participating organizations will announce their implementations as they become available.

About Proof
Proof is the identity authorization company that verifies people and organizations, issues high-assurance cryptographic credentials and creates tamper-evident evidence of what they authorize—whether they act directly or through AI agents. Proof has secured more than $640 billion in transactions for 10,000 organizations, including 16 of the Fortune 100. Learn more at proof.com.

HARDI, PHCC, and ACCA Announce Legal Challenge to Portions of EPA Technology Transitions Reconsideration Rule

Published

on

By

COLUMBUS, Ohio, June 25, 2026 /PRNewswire/ — Heating, Air-conditioning, & Refrigeration Distributors International (HARDI), Plumbing, Heating, Cooling Contractors – National Association (PHCC), and Air Conditioning Contractors of America (ACCA) today announced they have filed a challenge to parts of the Environmental Protection Agency’s (EPA) Technology Transitions Reconsideration Rule. The amended provisions increase demand for hydrofluorocarbon (HFC) refrigerants in the supermarket, retail food, and cold storage sectors as the supply is being reduced by law, violating the American Innovation and Manufacturing (AIM) Act and threatening to destabilize the refrigerant market. HARDI, PHCC, and ACCA represent wholesale distributors and contractors in the heating, ventilation, air conditioning, and refrigeration industry.

“For the EPA to completely abandon the timelines for transitioning to next-generation products proposed by industry in 2021 misses the mark,” said Talbot Gee, CEO of HARDI. “The final reconsideration rule’s treatment of commercial refrigeration is legally flawed, economically reckless, and directly at odds with the AIM Act. The EPA ignored industry data and over a decade of industry work to prepare for this transition, in violation of the AIM Act’s requirements. HARDI will always push back on agencies that violate the law in writing regulations affecting our industry.”

The joint petitioners strongly oppose the decision to extend deadlines for major commercial refrigeration applications, thereby allowing the continued manufacture of new systems using high-GWP refrigerants. The AIM Act requires a statutory phasedown of HFC supply across the economy, meaning quantities will continue to decline, while the final rule increases demand for refrigerants.

“PHCC members are working hands-on and helping customers navigate refrigerant changes every day,” said Cindy Sheridan, CEO of PHCC. “Allowing legacy refrigerants to be used longer in new commercial refrigeration systems creates confusion for the contractors who install and service this equipment and hurts consumers. The EPA’s own analysis projects a 12- to 24-percent increase in U.S. refrigerant prices by 2029 as a result of these delays, since the AIM Act will continue reducing the supply of these older refrigerants to support the domestic production of next-generation refrigerants.”

By allowing extended use of legacy HFCs in retail food refrigeration and cold storage, the final rule reduces the availability of refrigerants for other sectors, such as residential air conditioning.

“While ACCA appreciates EPA eliminating the install deadline for R-410A split-system equipment, the rule’s delayed refrigeration transition will significantly increase the demand for the limited supply of HFC refrigerants and will drive up costs for contractors and their customers,” said Martin Hoover, Interim President and CEO of ACCA. “This change will also increase pressure for a rushed transition to highly flammable A3 refrigerants and encourage a patchwork of state regulations.”

The joint petitioners support EPA’s decision to provide relief from the installation prohibition for existing split-system residential and light commercial air conditioners and heat pumps, a policy the organizations have long advocated for to prevent stranded inventory and avoid disruption for distributors, contractors, builders, and consumers.

The joint petitioners believe the final rule’s rationale rests on the false premise that the original Technology Transitions Rule had already increased grocery consumers’ costs. The commercial refrigeration restrictions at issue had not yet taken effect when EPA proposed the reconsideration rule and could not have been responsible for higher grocery prices.

The trade associations emphasized that the original Technology Transitions Rule applied to new equipment and did not require grocery stores, cold storage operators, or other businesses to replace existing systems. Existing equipment could continue to be used and serviced.

National Cybersecurity Voices Headline SBS CyberSecurity’s First Converge Cyber + AI Conference

Published

on

By

MADISON, S.D., June 25, 2026 /PRNewswire/ — Organizations are rolling out AI faster than they can govern it, and some of the sharpest minds in financial security are about to gather in one room to do something about it. SBS CyberSecurity has named the featured speakers for its inaugural Converge Cyber + AI Conference, headlined by KnowBe4 CISO advisor Erich Kron and social-engineering expert Brian Brushwood. Set for October 6–7, 2026, in Omaha, Nebraska, the two-day event will feature 23 planned sessions across governance, technical, and AI tracks. It’s designed for the security teams, executives, and governance, risk, and compliance (GRC) leaders ready to move from AI experimentation to secure implementation.

Built for financial institutions, fintechs, and other regulated organizations, Converge trades lecture-first programming for workshops, panels, and interactive formats. Attendees can join AI labs, a live capture-the-flag (CTF) tournament, and a lockpick village where they explore physical security. It’s open to any organization working to build a secure, AI-enabled business.

“The lineup tells you what Converge is really about,” said SBS CyberSecurity President and Co-Founder Jon Waldman. “We brought in some of the best security practitioners, from a national leader in human risk to a former FDIC executive to the engineers writing the code, because they are living in this space right alongside us. But Converge isn’t just about listening to great talks. It’s about the experience. We’ve built it to be interactive, whether that’s engaging directly with speakers, collaborating with peers, working through hands-on sessions, or spending time in our AI labs and CTF challenges. The goal is for people to leave with real connections and a clearer sense of how to apply what they’ve learned when they get back to work.”

Among the featured speakers, two will anchor the program with keynotes. Kron, a CISSP-ISSAP and former security manager for the U.S. Army’s 2nd Regional Cyber Center, opens the conference with a human-centered look at why security’s hardest problem is the people using the technology. Brushwood, host of the YouTube channel Scam Nation and a longtime translator of cons and social engineering for mainstream audiences, closes it.

“I’m absolutely thrilled to be speaking at Converge,” Brushwood said. “From the moment I heard about it, I was excited both by the focus on cutting-edge, boots-on-the-ground topics and by the commitment to usable takeaways. This is a must-not-miss event!”

Additional featured speakers bring firsthand experience setting policy and responding to incidents:

Michael Benardo, a 35-year FDIC veteran and former head of its Anti-Money Laundering and Cyber Fraud Branch, on cyber governance and where boards still fall shortTim Leonard, CIO of Commercial Bank of Texas, on wiring a personal AI command center from off-the-shelf partsChad Knutson, SBS CEO and co-founder, on executive decision-making during live incidents, deepfake and voice-cloning fraud, and AI governance that doesn’t stall innovation

The conference arrives at a useful moment for banks and credit unions. Examiners are starting to build AI into their expectations, yet many institutions still lack a clear picture of where AI is already in use across their environments and how to govern it. Previewed sessions, such as “From FFIEC to AI: What Examiners Will Expect Next,” are designed to close that gap with guidance leaders can defend.

Additional speakers and the full session schedule will be announced in the coming weeks. Registration is open at converge.sbscyber.com, where attendees can view the agenda and reserve a seat. Passes are $599, and a discounted room block is available at the DoubleTree by Hilton Omaha Downtown.

About SBS CyberSecurity: SBS CyberSecurity is focused on empowering your cybersecurity decisions. We provide robust risk management programs, IT audit services, and cybersecurity testing solutions, enabling you to protect your organization. For more information, visit sbscyber.com.
