Many concerning developments regarding privacy intrusions have emerged over the last several years, with high-profile and improper data scandals with Facebook to location data sold by cell providers to unauthorized individuals. Similarly, cryptocurrency platforms and blockchain networks have been the target of government surveillance programs in light of recent revelations.
Tackling privacy concerns requires implementing novel technologies in innovative ways to have any hope of achieving a comfortable level of privacy that enterprises, startup projects, and users seek.
At Sara Technologies, we understand the continually evolving nature of privacy and how it is at a premium today. We strive to provide our customers with secure and private solutions to reduce instances of data leakage, hacking, and surveillance of private financial transactions.
Deanonymizing Users With Network-Layer Attacks
Recent publications identifying methods for making connections between IP addresses and Bitcoin public keys through network traffic mapping have led to several important privacy enhancements in a multitude of public blockchain networks. Primarily, Dandelion++ with Bitcoin, Kovri with Monero, and the resurgence of Mixnets — such as Nym.
Protecting from network layer tracking — like IP mapping — requires what is referred to as overlay networks. Overlay networks have been around for years, are open-source, and are represented prominently by Tor and The Invisible Internet Project (I2P). Integrating these technologies with public blockchain networks that require anonymous and secure data transfers — such as sensitive IoT data transmission or high-value financial transactions — is necessary to tackle a growing legion of forensics analysts of blockchain.
Such initiatives are already underway with cryptocurrencies, however. Kovri — a C++ I2P implementation for Monero — is nearly completed while Dandelion++ — a promising gossip protocol optimization — is pegged for inclusion into Bitcoin’s protocol early this year.
Additionally, Mimblewimble projects like Grin and Beam came bootstrapped with Dandelion++ and are even compatible with the upcoming Nym protocol.
Several Bitcoin wallets are also beginning to include native Tor support — such as Wasabi Wallet. Monero is also considering integrating Sekreta — a more agile and robust overlay network protocol that includes a universal API.
Deciding on Privacy Solutions for Your Business or Project
If you are an enterprise or startup project in the developing decentralized Internet landscape, including crypto and blockchain, it is essential that you place a heavy emphasis on privacy. Data scandals can ruin reputations, lose millions in revenue, and degrade public trust in your organization. The robust Cyber Security services and privacy guarantees that cryptocurrencies provide at the protocol level with cryptographic primitives are unparalleled in their assurances. However, the protocol level is not sufficient as it does not address the entire security picture.
Network-layer attacks to leak data and deanonymize users will continue to evolve, leading to the necessity of impassioned response from developers seeking enhanced privacy. We are experienced and adept in managing different privacy solutions for various formats of organizations, IT systems, and network infrastructure. We can help guide your organization on the right path to protect your data and your users from third-party snooping adequately using Machine Learning solutions.
Further, if you’re looking to build a cryptocurrency project, we know how to integrate privacy-oriented overlay networks directly into wallet builds and continually keep an eye on the latest developments like Nym. Privacy is a right, and the choice to what extent you wish to retain that right is yours to make.
