Blockchain voting faces the challenge of ensuring voter privacy while maintaining transparency. Future research could explore cryptographic techniques such as ring signatures, homomorphic encryption, and zero-knowledge proofs for anonymizing votes while ensuring verifiability. Additionally, advancements in secure multi-party computation (MPC) could facilitate decentralized vote counting without revealing individual votes. Investigating these approaches could help strike a balance between confidentiality and transparency in voting systems.
