Security for Data Exchange in a Blockchain Ecosystem

As blockchain technologies increasingly underpin significant economic and social interactions, the need for advanced security mechanisms to protect data exchanged across these decentralized networks becomes crucial. This paper introduces a novel cryptographic scheme designed specifically for blockchain ecosystems to ensure the security, integrity, and confidentiality of data transactions. Our proposed scheme leverages a combination of homomorphic encryption and zero-knowledge proofs, integrated seamlessly with blockchain's inherent properties, such as decentralization and immutability.
