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.
