Organizations Using hash-card Tags for Verifiable Identity, Data Integrity, Merkle Proofs and On-Chain Anchoring
Discover organizations (the nav) that use the hash-card tag (the item) to implement verifiable identity, tamper-evident data integrity, Merkle-proof anchoring, and content-addressable storage across on-chain and off-chain workflows. This curated list shows projects, grants, and teams that integrate SDKs, APIs, verifiable credentials, and DID solutions to create audit trails, cross-chain anchoring strategies, and production-ready developer tooling. Use filters to narrow results by ecosystem, blockchain, category, or maturity to find sample repos, integration guides, enterprise references, and demo opportunities; review technical patterns for Merkle proofs, anchoring, and content addressing, compare integration approaches, and contribute to open-source implementations to accelerate secure, scalable hash-card adoption.
