Badge Trust Factors

Here are the verifiable trust factors that prove this badge's authenticity and integrity:

Cryptographic Signature

Unique cryptographic fingerprint prevents counterfeiting.
Like a unique DNA that can't be faked - so you know this badge is 100% real and hasn't been tampered with.

C05158C202DC841F12F65A99B1F8BC79D380C2FDFC4EE3720F434F5B62AC4B70
This SHA-256 hash is generated from the badge's content and metadata, creating an unforgeable digital signature. Any alteration to the badge would result in a completely different fingerprint, making it virtually impossible to counterfeit while ensuring complete data integrity and authenticity verification.

Verified Issuer Domain

Issuer controls verified domain with institutional accountability.
Like checking that a diploma really came from the school it claims - so you know it's not from a fake organization.

badgefed.org
Domain verification ensures that only the legitimate organization can issue badges from this domain. The issuer has been registered and issuing badges since their domain registration, providing institutional accountability and preventing impersonation attacks. This establishes organizational trust and credibility.

Decentralized Network Verification

Published on decentralized Fediverse for transparent verification.
Your badge exists on many computers, not just one - so it can't disappear if one company goes out of business.

ActivityPub Protocol
ActivityPub is a decentralized social networking protocol that ensures your badge exists on multiple independent servers across the Fediverse, providing transparent and public verification. This prevents single points of failure, censorship, and ensures the badge remains accessible and verifiable even if one server goes offline.

Open Badge Standard Compliance

Follows global standard for interoperability and verification.
Like having a universally accepted driver's license that works everywhere - so other organizations will recognize and trust your badge.

Open Badge v3.0 Specification
Open Badges is a globally recognized industry standard maintained by 1EdTech that ensures badges can be verified by any compliant system worldwide. This provides universal recognition, portability across platforms, and independent verification by third-party tools, making your badge internationally trusted and transferable.

Tamper-Evident Timestamp

Cryptographically protected issuance date prevents backdating.
Like a permanent marker that can't be erased or changed - so no one can fake when you earned this achievement.

2026-01-06 23:22:56 UTC
The timestamp is cryptographically included in the badge signature, making it impossible to alter the issuance date or backdate the badge without completely invalidating the entire signature. This prevents fraudulent claims about when achievements were earned and ensures chronological integrity.

Recipient Identity Verification

Identity cryptographically linked to prevent theft.
Like your name being permanently written inside - so no one else can steal your badge and pretend they earned it.

Maho 🦝🍻
The recipient's identity is verified through their authenticated account credentials and cryptographically linked to the badge signature, ensuring only the rightful owner can legitimately present this badge. This prevents badge theft, impersonation, and unauthorized use by other parties.

Verified Badge Program

Established program with published criteria and standards.
Like a recipe book that shows exactly what you did to earn this - there's a public webpage that anyone can check to see the requirements weren't made up or hidden.

View Program Information
This badge is part of an established program with publicly available information about the specific criteria, requirements, learning outcomes, and standards that must be met to earn the badge. This transparency establishes credibility and allows others to understand the achievement's value and rigor.

All trust factors have been verified and are cryptographically secured.
