Hello, I’ve bundled up the blockchain.rb sample from Awesome Blockchains into a ready-to-use out-of-the-box enterprise-strength blockchain library called blockchain.lite. Use like: b0 = Block.first( "Genesis" ); b1 = Block.next( b0, "Transaction Data..." ) ... and so on. Revolutionize the world with blockchains, blockchains, blockchains one block at a time. Happy blockchaining with ruby. PS: Proof-of-work upcoming :-)
