Advancing Trust in the Internet: Blockchain-driven Decentralized VPNs Leveraging Smart Contracts and PoS as Trust Factor Calculators

The imperative need for a secure and privacy-focused virtual private network (VPN) solution arises amidst growing concerns about centralized VPN architectures. The limitations of existing VPN models are examined, emphasizing issues related to single points of control, susceptibility to attacks, and potential privacy breaches. To counter these challenges, a decentralized VPN system built upon the blockchain client that supports smart contracts and proof of stake (PoS) is proposed. The blockchain-based architecture is designed to enhance security, transparency, and accountability in VPN operations. By leveraging distributed ledger technology, the proposed system eliminates the risks related to centralized control, offering a more resilient and tamper-resistant infrastructure. Smart contracts and PoS further contribute to the autonomous and trustworthy nature of the decentralized VPN. This contribution aims to advance the current discourse on VPNs by presenting a solution that addresses the shortcomings of traditional models.
