+W3b Stitch – Trust Engine for Decentralized Identity, Media Verification, and Credential Authentication
+
+Status: Open (anyone is allowed to apply)
+
+Proposer: rocketjays-cmyk
+
+Your Project(s): https://github.com/rocketjays-cmyk/w3b-stitch
+
+Projects you think this work could be useful for [optional]: Any ecosystem project requiring verifiable credentials, decentralized reputation systems, or authenticated media pipelines.
+
+Teams/People that could deliver the RFP [optional]: W3b Stitch core contributors, with potential for open-source community collaboration.
+
+Project Description :page_facing_up:
+
+W3b Stitch proposes a modular trust engine for the decentralized web, focused on three core pillars:
+
+Decentralized Identity (DIDs & Reputation): Enabling self-sovereign identity and trust scoring to empower users and organizations with verifiable digital presence.
+
+Media Verification & Curation: Anchoring media artifacts (images, videos, text) with hash proofs and blockchain anchoring to combat misinformation and content manipulation.
+
+Credential Authentication & Provenance: Issue, verify, and disclose credentials with privacy-preserving selective disclosure aligned with W3C Verifiable Credentials standards.
+
+The project is useful for Web3 ecosystems where trust, provenance, and verification are critical — including decentralized social platforms, credential issuers, supply chain traceability, and DAO compliance.
