BlockBallot is a next-generation blockchain-based electronic voting system developed to revolutionize Sri Lanka’s electoral process. Traditional elections in Sri Lanka rely heavily on manual, paper-based procedures, resulting in high costs, significant logistical challenges, security vulnerabilities, and delays in result announcements. BlockBallot directly addresses these issues by harnessing the power of blockchain technology, QR-based voter verification, and real-time digital vote counting to ensure a transparent, secure, and efficient voting experience for all citizens. The system enables each registered voter to be authenticated through a unique QR code, eliminating manual errors and reducing the potential for fraud or duplicate voting. Votes are cast electronically on tablets at polling stations, instantly encrypted and immutably stored on the Ethereum blockchain. This automated process delivers real-time vote counting, immediate results, and comprehensive audit trails—removing the delays and inaccuracies of manual counting. Voters receive a printed receipt as confirmation, enhancing trust and transparency. Accessibility and inclusivity are central to BlockBallot’s design, featuring a multilingual interface (Sinhala, Tamil, and English) and alternative voter identification options to accommodate all demographics, including those without traditional ID cards. The solution’s robust security measures, such as end-to-end encryption and role-based access controls, ensure compliance with both local and international data protection standards. By digitizing the voting process, BlockBallot significantly reduces costs, environmental impact, and barriers to participation, while enabling rapid, reliable, and tamper-proof elections. Ultimately, BlockBallot empowers every Sri Lankan to participate confidently in a secure, transparent, and modern democratic process.
