In this article, I’ll explain the security and risks related to this split by discussing the motives, technical differences, and the consequences to the eco-system.
Blockchain technology offers a more secure and reliable way of improving cybersecurity in organizations. This article discusses how blockchain-enhanced cybersecurity can help protect organizations from ransomware attacks like WannaCry and Petya.
Government and business leaders in every corner are experimenting with blockchain solutions. But these projects face the risk of becoming dead-on-arrival if their designers fail to prepare for the looming threat of quantum computers.
