Blockchain Voting: Securing the Future of Elections

?? In this instalment of Crypto Unlocked, we’re tackling one of the most discussed topics in blockchain, voting. With the 2024 US elections approaching and the events of the 2020 US election still fresh in many minds, trust in voting systems is a critical issue. Blockchain technology promises a solution by offering transparency, security, and decentralization.

We’ll break down how blockchain voting works, the risks and challenges, and what the future of blockchain voting could look like. Let’s dive in!

??? The Problem: Trust and Transparency in Elections

Recent elections have exposed vulnerabilities in traditional voting systems. The 2020 US presidential election led to claims of voter fraud, ballot tampering, and mishandling of mail-in votes. These issues culminated in the Capitol riots, which highlighted how fragile public trust in electoral systems can be.

Current voting systems rely on centralized authorities, whether governments or third-party agencies to collect, count, and secure votes. This introduces the risk of human error, manipulation, and delays in verifying results, all of which can damage voter confidence.

Key Challenges:

• Voter fraud concerns: Allegations of double-voting, vote tampering, and ineligible voters raise questions about the security of current systems.
• Lack of transparency: With centralized systems, voters often lack insight into how their votes are handled once cast.
• Manual errors: Even with digital enhancements, the counting and verification processes are prone to mistakes.

Clearly, there's a need for more secure and transparent election processes to restore public trust. Could blockchain be the answer?

?? Blockchain Voting: A Potential Solution to Election Challenges

Blockchain voting offers an alternative to centralized systems, using a distributed ledger to record votes securely and transparently. Each vote is encrypted and stored immutably on the blockchain, meaning it cannot be altered or tampered with once recorded. Here's how it addresses key election challenges:

1. Transparency

In a blockchain-based system, all votes are recorded on a public ledger, meaning the entire voting process is auditable in real-time. This transparency could dramatically reduce concerns about tampering, as every vote is publicly visible (though not connected to the voter’s identity).

2. Security

Blockchain’s cryptographic nature ensures that votes, once recorded, are tamper-proof. This makes it nearly impossible to change a vote after it has been cast, which helps prevent fraud and manipulation. Additionally, Decentralized Identifiers (DIDs) can be used to verify voter eligibility without compromising privacy.

3. Decentralization

Instead of relying on a single authority, blockchain voting operates across a network of nodes, where no single entity controls the system. This eliminates the risk of central authorities manipulating election results.

?? How Does Blockchain Voting Work?

Blockchain voting operates using a few key steps:

1. Voter Authentication: Voters verify their identity through DIDs, proving eligibility without revealing personal details.
2. Casting a Vote: Voters submit their vote, which is recorded on the blockchain in an encrypted format.
3. Consensus Mechanism: Votes are verified and added to the blockchain through consensus mechanisms, ensuring they are counted accurately.
4. Real-Time Auditability: The blockchain ledger is publicly accessible, meaning votes can be verified at any time without compromising voter privacy.

Estonia’s e-residency program is a real-world example, using blockchain to securely and transparently handle online voting.

?? The Evolution of Blockchain Voting

Blockchain voting is a promising technology, but it’s still evolving. Initially, blockchain was introduced to secure financial transactions like Bitcoin, but today, it’s being applied to a wider range of use cases, including voting. However, this evolution has highlighted a few shortcomings, which we’ll explore below.

?? Risks and Considerations in Blockchain Voting

While blockchain voting offers transparency and security, there are some significant risks and challenges to consider:

1. Device Security

Blockchain doesn’t protect voters from using compromised devices. If a voter’s device is infected with malware, their vote could be manipulated before it’s even recorded on the blockchain.

2. Voter Coercion

Blockchain’s transparency could allow malicious actors to coerce voters into revealing how they voted. Even with encryption, there’s potential for individuals to be pressured into showing their transaction on the public ledger.

3. Scalability and Cost

Running a national election on a public blockchain could be resource-intensive, both in terms of energy and computational power. This poses a problem for scalability and cost-effectiveness, especially in countries with large populations.

4. Immutability Challenges

Blockchain’s immutability is a double-edged sword. While it ensures that votes can’t be tampered with, it also means errors are permanent. If a flaw is discovered in the system, correcting it can be incredibly difficult without significant disruption.

?? Bespoke Solutions: Hybrid Blockchain Voting Systems

To address these challenges, a hybrid approach may be the solution. Here’s what a bespoke blockchain voting system could look like:

1. Private Blockchain with Paper Backup

Using a private blockchain, where only authorized participants (like election officials) can validate transactions, could offer both control and transparency. A paper backup ensures the system is verifiable through traditional means in the event of technical issues. West Virginia’s pilot in 2018 used a private blockchain for military personnel voting abroad.

2. Zero-Knowledge Proofs for Privacy

With Zero-Knowledge Proofs (ZK Proofs), voters can verify that their vote was counted without revealing how they voted. This guarantees anonymity while ensuring the integrity of the results.

3. DIDs for Secure Authentication

Voters can authenticate through Decentralized Identifiers (DIDs), proving their eligibility without compromising personal data. Estonia’s blockchain voting system already uses DIDs to ensure only eligible voters participate.

4. End-to-End Verifiability (E2E-V)

Blockchain-based E2E-V systems give voters a receipt that allows them to verify their vote was counted without exposing the content of their vote. This ensures both transparency and privacy.

?? The Future of Blockchain Voting

As blockchain technology continues to evolve, blockchain voting has the potential to transform the way we conduct elections globally. However, its future will depend on addressing the risks and creating a hybrid solution that balances security, privacy, and transparency.

What to Expect in the Future:

• Innovation in Privacy Protections: Expect increased use of technologies like ZK Proofs to protect voter privacy.
• Scalability Improvements: Future blockchain voting systems will likely focus on making the technology more energy-efficient and scalable.
• Integration with Traditional Systems: Blockchain will likely be used in conjunction with paper ballots and other traditional methods to create a fail-safe and verifiable election process.

Blockchain voting, combined with traditional verification, has the potential to restore public trust in elections while ensuring security, transparency, and voter anonymity.
