The Superior Electoral Court (TSE) in Brasília concluded the final security step for Brazil’s 2026 General Elections today, sealing the source code for the electronic voting and tallying systems to be used in October. The procedure, finalized in the Digital Signature and Sealing Ceremony on Friday, September 4, is the ultimate measure by the TSE to guarantee the integrity of the country’s highly-digitized voting process against any post-development alteration. The ceremony officially locks the software that will run on all electronic voting machines nationwide, addressing a central political risk concern that has frequently been exploited by critics of the system over the last election cycles.
