Frequently Asked Questions
Get clear answers on how Chainscore Labs delivers secure, verifiable data feeds for tokenized real estate.
Traditional oracles deliver raw data (e.g., "Property Value: $1.2M") with trust assumptions. Our ZK-Oracle delivers cryptographically verifiable proofs alongside the data. This means any on-chain protocol can independently verify that the appraisal data (like comparables, square footage, market trends) was computed correctly from trusted sources without revealing the underlying private data. This eliminates single points of failure and enables truly trust-minimized lending, trading, and securitization.
