Martian Republic is the app of the Marscoin community: a wallet, a public identity and a vote, all held on your own phone. YOUR WALLET, YOUR KEYS • A Marscoin wallet and a Bitcoin wallet from the same twelve words. • The words stay on your device. There is no account to open and nothing for anyone to freeze or reset. • A guided setup that explains each step in plain language. BITCOIN TO MARSCOIN, PERSON TO PERSON • Swap Bitcoin for Marscoin with an atomic swap. The two coins are locked on their own blockchains and released together. • The app verifies the seller's lock on two independent nodes before it lets you pay. • Every step is shown as it happens. If a swap does not complete, your Bitcoin returns to you automatically. • You can also offer your own Marscoin for Bitcoin, at a price and with limits you set. CITIZENSHIP • Publish a public civic record and be endorsed by other citizens. • Your identity is your wallet address. There is no password and no central register. CONGRESS AND THE PUBLIC SQUARE • Read proposals and discuss them in the forum. • Cast a ballot from your phone. Votes are recorded on the Marscoin blockchain, where anyone can count them. THE NETWORK, LIVE • See every service your phone talks to and how quickly each answers. • Watch both blockchains advance in real time. OPEN SOURCE The app and the Republic's website are open source. Learn more at martianrepublic.org and marscoin.org. Swaps move real coins and cannot be reversed. Start with a small amount.
