Amazon Highlights the Moral Ambiguity of Decentralization

From cryptocurrency to mesh networks, many technologists agree that decentralization is a major philosophical underpinning to the development of cutting-edge internet technologies. There are many benefits to decentralization which, at its core, involves moving the functions of a technology or platform from a centralized decision-making hub (for example, Facebook’s massive data collection and content moderation projects) to a more user-controlled experience. 

A decentralized web means that authoritarian regimes cannot censor content, or that we can save bandwidth by sharing it. A decentralized financial system would cut out market power from a consolidated few market makers and boost individual standing in a digital credit system. In New York City, we enjoy the NYC Mesh, one of many regional mesh-based internet service providers that expand internet accessibility for all.

But in these early days of decentralized technology, application and implementation are critical to its usability and safety. After all, it’s still a cutting-edge concept in technology, and it will come with many challenges that could threaten the security and privacy of users. Leave it to a morally ambiguous tech behemoth like Amazon to stress test this.

This week marks a radical expansion for Amazon’s Sidewalk product, a mesh network that seeks to render Amazon hardware devices into decentralized internet nodes. Amazon has tried to get ahead of the inevitable privacy debate by producing a detailed white paper on the security challenges. But despite robust technical controls and policies, along with all the proper encryption you would expect, there is nonetheless a deficit of understanding between the philosophy of decentralization and the technology.

Our biggest problem with Amazon Sidewalk is best described as an utter lack of consent on the part of the company. For one, Amazon is automatically entering all supported hardware into the Sidewalk mesh network. For those Amazon Echo owners who aren’t keeping up with tech news like us nerds, that means that a device they own is now part of a large-scale mesh network, sharing its internet connection with strangers’ devices that need it, likely without their knowledge.

Now, there are some actually cool techniques that the Sidewalk network uses to ensure that the connection you are sharing is abused by a malicious actor. The Sidewalk technical whitepaper notes mechanisms like continuous network monitoring, multiple authentications at ingress and egress, and the use of various identifiers and authentications to ensure only legitimate packets are honored onto the network. 

Nonetheless, it’s only through practical usage that hackers and security researchers discover all the gaps in the approach, and potential areas where privacy and security may be at risk. For one, we are looking at how network hardware identifiers such as MAC addresses and transaction IDs can be fingerprinted and profiled via the Sidewalk network, and how a user might be triangulated.
