Top 10 Decentralized Email Providers

A recurring theme on the topic of blockchain technology impacting various industries is it improves certain aspects of each one. With election security, for example, blockchain is a large step towards fixing the problems that stem from traditional paper ballots. More and more people are starting to accept electronic voting. Those supporting blockchain voting are of the belief that it adds a sense of authenticity and anonymity to electoral voting.

Admittedly, blockchain technology will not fix every issue, but incorporating it into pre-existing systems will result in some notable improvements. The best way to summarize blockchain’s intentions is with a statement from a McKinsey article. Blockchain, according to the writers, is “a solution looking for a problem.”

With that in mind, email and email marketing is yet another industry where blockchain is leaving its mark. Patrick Ben Koetter of Dot Magazine describes blockchain as a “contract mechanism,” of which certain features are applicable to email. It is tamper-proof and can be fully automated. With these factors, plus the fact that blockchain aids in the security of voting, it is unsurprising that more people are looking into decentralized email providers.
