MMGen = Multi-Mode GENerator ============================ ##### a Bitcoin cold storage solution for the command line ### Install the offline bitcoind: The bitcoin daemon on the **offline machine** is used solely for signing transactions and is therefore run without a blockchain. The version bundled with the prebuilt Bitcoin-QT is just fine for this purpose. Windows and Linux binaries can be obtained [here][00]. After installation, locate the bitcoind executable, place it on your execution path and start it with the command: $ bitcoind -daemon -maxconnections=0 Note that in the absence of a blockchain the daemon starts very quickly and uses practically no CPU once running. Thus a low-powered computer such as a netbook can serve quite nicely as an offline machine for signing transactions. [00]: https://bitcoin.org/en/download
