I was looking for a gem that works with latest bitcoin daemon/litecoin daemon
and i was not able to find one,
So I have created my own gem,
it has 8 modules
Blockchain, Control, Generating, Mining, Network, RawTransactions, Util, Wallet
and each module, contains related methods, which you can call
puts Berycoin::Blockchain::getnewaddress
should create and return a new berycoin wallet address
If you want to use this gem, or want to study what methods it has, you can visit this documentation link
it requires few initial steps for setup
