# Digital Signatures Keeta Network uses digital signatures for digitally signing [blocks](/components/blocks.md) and [votes](/architecture/consensus/votes.md), and cryptographic hashing for referencing blocks. The network currently supports 3 different cryptographic algorithms for performing digital signatures, but is extensible to support additional algorithms, as well as deprecating algorithms in the future should the need arise. The currently supported algorithms are: * EcDSA with secp256k1 * EcDSA with secp256r1 * Ed25519 --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.keeta.com/security/digital-signatures.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
