Black Lake Unveils Harbor Verify for Onchain Asset Verification

Black Lake Digital Markets has launched Harbor Verify, a browser-based tool for verifying tokenized loans. The tool uses cryptographic proofs and onchain commitments to confirm that each loan in a pool meets its published eligibility criteria without revealing private borrower data.

The platform allows reviewers to independently verify the integrity of a portfolio by running two checks: one confirming that the correct eligibility rules were used, and another ensuring that the loan belongs in the pool. Harbor Verify uses multiple patent-pending methodologies and can be accessed at harbor-verify.com.

Black Lake is applying this model first to a $25 million portfolio of residential mortgage loans. The tool's launch marks an effort to simplify the process of verifying assets onchain, removing the need for bilateral reports, restricted data rooms, and attestations from parties assembling or reviewing the portfolio.
