eMark (DEM)

eMark (DEM) is a Proof-of-Work cryptocurrency positioned as a German digital currency, whereas Bitcoin is a global project. Technologically they share the same core concept — mining and a decentralized ledger — but eMark targets the German-speaking community and has its own blockchain, network and parameters. It's a much smaller project in terms of adoption and ecosystem.

eMark runs on a Proof-of-Work consensus, meaning miners compete to solve computational puzzles, and whoever wins gets to add the next block of transactions. This makes the network decentralized and secure without needing a central authority, since altering the ledger would require redoing an enormous amount of work.

Yes, eMark is a mineable coin — new DEM coins are created exclusively through mining as block rewards. There's no pre-mine-style central issuance you can buy from a company; supply grows purely as miners secure the network. You can join a mining pool or mine solo with suitable hardware and the official wallet software.

You store DEM in the official eMark wallet, which you can download from the project's site at deutsche-emark.de. The wallet lets you send and receive coins, and if you keep it running, you also support the network. As with any crypto, back up your private keys — losing them means losing access to your coins permanently.
