US Post Office Patents a Novel Blockchain-Backed Mail-In Voting System

The United States Postal Service (USPS) has filed a patent for a novel mail-in voting system that leverages blockchain technology, a move that could significantly bolster the security and integrity of absentee ballots amidst growing concerns about election fraud and the pandemic-driven shift towards mail-in voting. The patent, initially filed in February 2020 and recently published by the U.S. Patent and Trademark Office, outlines a system designed to enhance voter identification, ensure ballot anonymity, and prevent tampering with electronic voting results. This development comes at a critical juncture for the upcoming November 3, 2020, U.S. presidential election, where a substantial portion of the electorate is expected to cast their votes by mail.

Context of Mail-In Voting and Blockchain Technology

The 2020 U.S. presidential election campaign has been significantly shaped by the COVID-19 pandemic. Public health concerns have led many states to expand or encourage mail-in voting options to reduce the risk of in-person transmission of the virus. However, this shift has ignited a contentious debate, with President Donald Trump expressing strong opposition to widespread mail-in voting, frequently asserting that it is susceptible to fraud and could unfairly benefit his opponent, Joe Biden. These concerns were amplified when President Trump was accused of blocking funding for the USPS, an action that critics argued was intended to impede the postal service’s capacity to handle the anticipated surge in mail-in ballots.

Blockchain technology, the distributed ledger system that underpins cryptocurrencies like Bitcoin, has garnered attention for its inherent security features. Its immutable and transparent nature makes it exceptionally difficult to alter or hack data once it has been recorded on the chain. This characteristic presents a compelling potential solution for enhancing the security of electronic voting systems, particularly in the context of mail-in ballots, where concerns about ballot integrity are often paramount. The USPS’s patent application signals an acknowledgment of this potential and an effort to integrate such advanced technology into its operations.

The Proposed Blockchain-Backed Voting System

The patent application details a system designed to address several key challenges associated with mail-in voting. At its core, the system aims to provide a secure and verifiable method for voters to cast their ballots remotely while maintaining the privacy of their choices.

Key features of the proposed system include:

• Voter Identification and Ballot Issuance: The system proposes a method where voters would receive a "computer-readable code" via mail. This code would serve as a crucial element for initiating the voting process. The patent application suggests that this code would be linked to the voter’s identity, ensuring that only eligible individuals can cast a ballot.
• Digital Voting and Verification: Upon receiving the mailer, voters would be able to confirm their identity and the associated ballot information digitally. This verification step is designed to ensure that the ballot being accessed is indeed for the correct voter and election.
• Separation of Identification and Votes: A critical aspect of the proposed system is the separation of voter identification from the actual vote. This mechanism is vital for preserving ballot secrecy and preventing any potential linkage that could compromise the anonymity of the voter. The system aims to ensure that while the eligibility of the voter is confirmed, the content of their vote remains confidential.
• Secure Storage on a Distributed Ledger: Once cast, the votes would be recorded and stored securely on a distributed ledger, leveraging blockchain technology. This distributed nature means that the vote data would not reside in a single, vulnerable location but would be spread across multiple nodes in a network. The immutability of the blockchain would ensure that once a vote is recorded, it cannot be altered or deleted without detection, thereby preventing tampering or fraudulent modifications.

The USPS’s patent application, spanning 47 pages, includes detailed illustrations and explanations of how this blockchain-based voting system would function. The agency articulated its vision for the technology in its patent filing, stating:

"The security of a voting system can be increased by using the dependability and security of the United States Postal Service or similar entity, and this can be incorporated with a secure computer system using a blockchain or distributed ledger to ensure vote security and to prevent tampering or modification of electronic voting results."

This statement highlights the USPS’s recognition of its own established trust and infrastructure as a foundational element, which can then be fortified by the technological capabilities of blockchain.

Chronology of the Patent Application

The timeline leading to the publication of this patent is as follows:

• February 2020: The initial patent application for the blockchain-backed mail-in voting system was filed by the United States Postal Service with the U.S. Patent and Trademark Office.
• August 2020 (Early Weeks): The U.S. Patent and Trademark Office published the patent application, bringing the details of the proposed system into the public domain. This publication occurred during a period of heightened political tension surrounding mail-in voting for the upcoming presidential election.

Broader Implications and Analysis

The USPS’s move to patent a blockchain-based voting system carries significant implications for the future of elections in the United States and potentially globally.

Key implications include:

• Enhanced Trust in Mail-In Voting: The patent, if implemented, could serve to allay public concerns about the security of mail-in ballots. By incorporating a technology known for its robustness against fraud and tampering, the USPS could build greater confidence among voters and election officials.
• Technological Advancement in Elections: This initiative represents a notable step towards modernizing election infrastructure, which in many areas still relies on outdated systems. The integration of blockchain could set a precedent for other government agencies and electoral bodies seeking to improve the security and efficiency of their processes.
• Addressing Political Divides: While the patent itself is a technological endeavor, its potential impact could extend to bridging the partisan divide over election integrity. A demonstrably secure mail-in voting system, backed by a trusted institution and advanced technology, could potentially mitigate some of the political rhetoric surrounding the issue.
• The Role of the USPS: The patent underscores the USPS’s ambition to play a more integral role in the democratic process, moving beyond its traditional function of mail delivery to becoming a key player in ensuring secure and transparent elections. This could also have implications for the financial sustainability and public perception of the USPS.

However, it is crucial to note that a patent represents an intention and a concept, not a guaranteed product. The path from patent to a fully implemented and operational system is often long and complex, involving further research, development, testing, and significant investment. The practical challenges of deploying such a system nationwide, ensuring accessibility for all voters, and integrating it with existing electoral frameworks would need to be thoroughly addressed.

Reactions and Potential Future Developments

While the patent application was a unilateral action by the USPS, the concept of blockchain in voting has been explored by various entities. Private companies and researchers have also proposed and patented similar blockchain-based voting solutions. The USPS’s involvement, however, brings a unique level of gravitas due to its status as a federal agency with a vast logistical network.

It is plausible that this patent will spur further discussion and collaboration among election security experts, technology developers, and policymakers. Given the upcoming election and the ongoing debate, the USPS may face pressure to provide more details on its roadmap for this technology.
