MultiGroestl Classic is a lightweight "thin client" Groestlcoin wallet for Windows, MacOS and Linux based on groestlcoinj. Its main advantages over the original Groestlcoin client include support for opening multiple wallets simultaneously, and not requiring the download of the entire block chain.

If you are an ordinary user of Groestlcoin and simply want a wallet that just works without hassle, then MultiGroestl Classic is the right choice for you.

Changelog MultiGroestl Classic v0.5.19 :
• Updated DNS seeds
• Updated Checkpoints
• Updated Protocol number
• Bloom filters enabled
• Upgrade to Install4j as installer
• New utility "Tool | Check Private Keys"
• Stronger branding as MultiGroestl Classic to help distinguish it from our new wallet, MultiGroestl HD
• Adjust your transaction fees using a fee slider
• Link in header to make it easy for you to try MultiGroestl HD

• Multiple wallets can be open at the same time
• Quick and easy to install across all major desktop operating systems (Windows, Mac, Linux)
• Secure by design - all private keys are kept encrypted on your local machine (or on a USB stick)
• Faster - Synchronizes with the network by downloading the block headers only very quickly
• Lighter - It does not require a new user to download the entire Groestlcoin chain and store it
• Easy - no need to search for extra nodes and edit the conf file
• Shows the last GRS to fiat rates from Poloniex
• Import and export your private keys
• Chart of your balance over the last 30 days
• Free and decentralised - Open Source under MIT license
• International - multiple languages
