Significant scalability improvements are essential for blockchain-based electronic voting systems to be viable for large-scale elections. Current blockchain networks struggle with transaction speeds and high fees, limiting the ability to handle millions of simultaneous votes. Future research could focus on Layer 2 solutions like state channels and side chains, or innovative consensus methods such as Proof of Stake (PoS) and sharding. Additionally, developing lightweight blockchain protocols specifically designed for voting may yield promising election-specific solutions. Ultimately, enhancing network throughput is crucial for effective digital voting.
