Sequioa Voting Systems makes voting machines, e.g., the physical devices that one uses to enter votes. Historically, these voting machines are called "voting systems," which can be confusing since other people use the term "voting system" to refer to the method of counting votes, e.g., instant runoff voting.

Sequioa has recently announced that it will release an open-source voting system. Here is a quote from the press release:

• “Security through obfuscation and secrecy is not security,” said Eric D. Coomer, PhD, Vice President of Research and Product Development at Sequoia Voting Systems. “Fully disclosed source code is the path to true transparency and confidence in the voting process for all involved. Sequoia is proud to be the leader in providing the first publicly disclosed source code for a complete end-to-end election system from a leading supplier of voting systems and software. Sequoia’s Frontier Election System has been designed to comply with all the current Election Assistance Commission’s Voluntary Voting System Guidelines.”

Sequioa's announcement comes shortly after an announcement by the Open Source Digital Voting Foundation regarding the first release of its voting system (i.e., machine) code.

Using OpenSTV and one of the above voting systems could allow a government to have an end-to-end open source election using instant runoff voting, the single transferable vote, or any of the other methods supported by OpenSTV.
