Sibling Hashes

Hash

Sibling hashes, within the context of cryptocurrency and derivatives, represent a cryptographic linkage between related data blocks or transactions. This linkage is typically achieved through the inclusion of a previous block’s hash within a subsequent block, forming a chain of dependencies. The concept extends to options and derivatives by associating hash values with specific contract parameters, trade executions, or collateral positions, enabling verifiable data integrity and audit trails. Consequently, alterations to any linked data would necessitate recalculation of all subsequent hashes, immediately revealing tampering.
