What is a Blockchain-Based Voting System?
A blockchain-based voting system is a digital voting platform that uses blockchain technology to conduct and manage elections.
Blockchain, a decentralized and distributed ledger, records transactions across multiple computers in such a way that the records are secure, transparent, and immutable—meaning they cannot be altered retroactively.
In a voting context, blockchain technology can be used to create a secure and transparent system for casting, recording, and counting votes.
Each vote is treated as a transaction on the blockchain, where it is encrypted and securely stored.
Because the blockchain is decentralized, no single entity controls the entire system, making it resistant to tampering or fraud.
How Blockchain Voting Systems Work

This section explains the step-by-step process of how blockchain voting systems operate, from voter registration to the announcement of election results.
Voter Registration
In a blockchain voting system, the first step is voter registration. Voters must sign up to participate in the election, similar to how they would register in a traditional voting system.
However, in blockchain voting, voters receive a digital identity, which is often verified using government-issued identification.
The digital identity serves as a unique identifier for each voter on the blockchain. This process ensures that each person can vote only once, preventing voter fraud.
The digital identity is securely stored on the blockchain, making it tamper-resistant.
For example, Estonia, a leader in digital governance, uses a blockchain-based system to allow its citizens to vote online, where digital identities are verified using a secure ID card.
Ballot Creation
Once registered, a digital ballot is created for each voter on the blockchain. This ballot is linked to the voter’s digital identity but is still anonymous to protect voter privacy.
Each digital ballot is unique and tailored to the individual voter, containing the specific candidates or issues they are eligible to vote on.
The blockchain ensures that no one can create fake ballots or alter the ballots once they are issued. The use of cryptographic techniques ensures that the ballot cannot be tampered with once it is created.
An example is the use of blockchain in the 2018 Sierra Leone elections, where ballots were securely issued on a blockchain platform to prevent tampering.
Casting Votes
In a blockchain voting system, casting a vote is done through a transaction on the blockchain. Voters use their digital identity to access their ballot and select their choices.
Once the vote is cast, it is encrypted to ensure privacy and then stored on the blockchain.
The transaction, which is the vote, is visible on the blockchain, but it is encrypted, ensuring that the content of the vote is not visible to others. This process makes the voting secure, transparent, and anonymous.
The 2019 Moscow City Duma election pilot used this method, where citizens cast their votes using a blockchain-based platform.
Vote Counting
After all the votes are cast, the blockchain system automatically counts the votes. The counting process is transparent because it occurs on the blockchain, where anyone can verify the transactions.
However, since the votes are encrypted, the secrecy of individual votes is maintained.
This automated counting reduces the chances of human error or manipulation during the vote tallying process. The transparency of the blockchain allows any party to audit the vote count in real time.
An example is the use of blockchain in the 2020 Voatz pilot in the United States, where votes were automatically counted and the results could be verified by third parties.
Results Announcement
The final step in the blockchain voting process is the announcement of the results. Once all votes are counted, the results are published on the blockchain.
Because the blockchain is immutable and transparent, anyone can verify the accuracy of the results by checking the recorded transactions.
This level of transparency helps to build trust in the election process, as it is nearly impossible to alter the results without detection.
The 2020 U.S. Presidential election saw several states, such as West Virginia, using blockchain-based voting for overseas military personnel, where the results were verified through the blockchain system.
Benefits of Blockchain in Elections
Blockchain brings numerous benefits to election systems some of which are;
