Blockchain enables verifiable asset ownership by recording tamper-evident ledgers that map assets to tokens. Fungible tokens represent interchangeable value; non-fungible tokens capture unique provenance. Transfers, custody, and verification occur on distributed ledgers with cryptographic proofs and attestations. Interoperability standards reduce…

Blockchain-based digital identity anchors credentials on a tamper-evident ledger, enabling cryptographic binding and portable proofs. Verifiable credentials support selective disclosure and zero-knowledge exchanges, reducing data exposure while preserving user control. Issuers establish trust anchors; revocation and offline verification remain feasible…
