Blockchain Block Generation via Digital Signature Verification

The patent introduces a signature device as an intermediary between block generation and validation. The signature device verifies the legitimacy of block generators using digital signatures, acting as a trusted mediator that enhances network security without requiring all nodes to perform complex verification operations. This resolves the contradiction by centralizing the verification function in a dedicated component.

The patent implements preliminary digital signature verification of block generators before allowing them to create blocks. By pre-validating the identity and authority of block generators through signature verification, the system ensures network security is established in advance, preventing unauthorized block generation while maintaining a relatively simple ongoing block creation process.

The patent extracts the digital signature verification function from the general block validation process and assigns it to a dedicated signature device. This separation allows signature verification to be performed only when needed (during block generator validation) rather than on every block operation, reducing overall computational overhead while maintaining validation accuracy where critical.

The signature device performs self-verification of block generator identities using pre-established cryptographic keys. By using asymmetric cryptography where the signature device holds the verification key and block generators hold signing keys, the system enables automated self-validation without requiring intensive computational resources from network nodes, thus reducing energy consumption while ensuring reliable validation.
