On January 2nd, according to bitcoin advocate Dennis Porter, Swiss lawmaker Samuel Kullmann is promoting efforts to include bitcoin in the Swiss constitution. The plan requires collecting 100,000 signatures within 18 months to force cantons (cantonal assemblies) to vote on bitcoin as part of the constitution. Although this proposal faces challenges, if it successfully collects enough signatures, it will prompt all cantonal assemblies to learn more about bitcoin. Previously, the Swiss federal government has started reviewing bitcoin-related referendum proposals.
