Cryptographic Commitment

A cryptographic commitment allows an entity to bind itself to a specific piece of information while keeping that information hidden until a later time. This is widely used in solvency proofs to commit to a total liability amount before revealing the underlying data.

The commitment must be both hiding, meaning the data cannot be guessed, and binding, meaning the entity cannot change the data once committed. This prevents the institution from altering its liability figures after the audit has begun.

By providing a proof of commitment, the entity demonstrates its intention to be transparent without compromising competitive or private data. It is a core primitive in modern privacy-preserving financial protocols.
