The Catholic Church's method for choosing a new pope is one of the most secure voting systems in existence. This process, known as a papal conclave, has been refined over nearly 2, 000 years. It offers valuable lessons for modern democracies struggling with secure voting.

The upcoming papal election is already stirring debates. Some groups in the US are pushing for a more conservative pope, while others support the liberal approach of the late Pope Francis. The outcome may heavily depend on the cardinals appointed by Francis, who make up a significant portion of the voting body.

Despite the controversies, the voting process itself is straightforward and transparent. Cardinals from around the world gather in the Sistine Chapel, write their choices on cards, and swear an oath with each vote. The process is overseen by three randomly chosen scrutineers, and every vote is announced aloud. This transparency helps to ensure the integrity of the election.

There are three key takeaways from the papal voting process. First, transparency is crucial. Every step is visible to all participants, even though the votes themselves are secret. Second, smaller elections among known voters are less prone to manipulation. Third, a long-evolved selection process can become remarkably effective.

However, applying these lessons to large-scale elections, especially in countries like the US, is challenging. The scale and complexity of US elections make secure voting difficult, particularly when technology is involved. Hackers regularly expose flaws in digital voting systems, proving that purely digital voting is not secure.

To minimize risks, experts suggest using physical ballots that can be recorded and counted electronically. This method allows for risk-limiting audits, which can help ensure the integrity of the election. While there are broader threats to democracy, such as disinformation and foreign interference, learning from the papal election process can help improve voting systems.

Over centuries, papal elections have faced numerous challenges, from bribery to extended wrangling. The process has adapted and improved through constant verification and good faith. Today, hackers can play a role in identifying risks and proposing safer solutions for voting systems worldwide.
