Can XRP Be Used To Fight Spam Email? Here’s a Proposal

Before he died, Stephen Hawking once said “we are all now connected by the internet, like neurons in a giant brain”. It is true, we are. The internet has had a direct impact on everyone who uses this vast “neuron like network”. Not only did it improve efficiency but it has made our lives more productive and useful. Technopedia defines the internet as a “a globally connected network system that uses TCP/IP to transmit data via various types of media.” Like the blockchain, the internet is completely decentralized and a “peer-to-peer (P2P) communication network.” Continue reading Can XRP Be Used To Fight Spam Email?
