RedTreeBlueTree Applies for "Key Commitment and Opening Commitment" Patent, Targeting Blockchain and Other Fields

Beijing-based RedTreeBlueTree Technology Co., Ltd. recently filed a patent application titled "Method, Blockchain, Product, and Device for Commitment and Opening Commitment of Keys," with publication number CN118921167A and an application date of July 2024. The patent aims to achieve an association binding between identities (IDs) and keys through the construction of a commitment primitive and utilizing zero-knowledge proof technology for identity verification.

• The patent abstract reveals that RedTreeBlueTree's patent primarily addresses the issue of securely associating entity identities (IDs) with keys. Its core idea involves using a commitment primitive to bind secret IDs to private keys in a specific way. Specifically, the commitment phase associates the secret ID (sk) with the private key, using the formula sk = gIDA + undisclosed secretB, where AB equals the inverse of the order of group G, and g is the smallest primitive root. The verification phase then removes the ID to obtain pk_charller = (gIDA)pk and utilizes zero-knowledge proof technology to demonstrate the existence of a secret k that satisfies the equation pk_charller = (gB)kG. The patent discloses two non-circuit-based zero-knowledge proof methods.

Furthermore, the patent provides commitment/opening commitment schemes for SM2 and secp256k1 algorithms, outlining details regarding the components involved for the committer P, prover P, and verifier V. In terms of application, the patent encompasses areas such as commercial cryptography products, digital certificate products, blockchain systems, devices, and programs.

The patent emphasizes that the invention offers advantages such as binding, anonymity, decentralization, and compatibility/transparency, playing a significant role in enhancing data security and privacy protection.

It's noteworthy that the technologies involved in this patent, such as commitment schemes and zero-knowledge proofs, have wide-ranging applications in fields like blockchain. This demonstrates that RedTreeBlueTree is actively exploring the integration of its technology into cutting-edge fields, offering more secure and reliable technical solutions for relevant industries.
