Why the Creator of Signal Protocol Questions True Decentralization
Moxie Marlinspike, renowned for developing the secure messaging application Signal, is a prominent advocate for digital privacy. Despite his reputation, he remains a vocal critic of Web3 technologies, cryptocurrencies, and NFTs. Marlinspike asserts that the decentralized future championed by proponents is largely a façade, concealing traditional centralized practices. ForkLog has taken a closer look at the validity of his claims.
Who is Moxie Marlinspike?
Moxie Marlinspike, whose real name is Matthew Rosenfeld, is a significant personality in the realms of cryptography, cybersecurity, censorship circumvention, and online anonymity. He founded Open Whisper Systems in 2013, which later transitioned into the nonprofit Signal Foundation. The flagship product, Signal messenger, is recognized as the benchmark for secure communication, utilizing the Signal Protocol for end-to-end encryption. This protocol is now also integrated into platforms like WhatsApp and Google Messages. Marlinspike’s pragmatic approach to technology emphasizes user-centric outcomes over ideological ideals, valuing simplicity, reliability, and genuine privacy. His critical perspective on Web3 was articulated in a personal blog in early 2022.
The World Does Not Desire to Operate Its Own Servers
Marlinspike’s central argument posits that Web3 fails to address the fundamental issue of dependency on service providers that plagues the internet. Users generally prefer not to manage their own servers for application interactions, prioritizing convenience instead. While Web3 applications claim to be decentralized, most still rely on major service providers to communicate with the blockchain. For instance, wallets like MetaMask and Phantom typically utilize services such as Infura and Alchemy to gather data from networks like Ethereum or Solana. This arrangement effectively substitutes Infura for a personal server. Should these providers face shutdowns or decide to censor content, numerous applications would become nonfunctional. Marlinspike contends that Web3 has simply substituted one form of centralization for another, albeit one that is more complex and less efficient.
The Illusion of Ownership: An NFT Example
To illustrate the shortcomings of non-fungible tokens (NFTs), Marlinspike created an NFT that displayed different images based on the platform it was viewed on, such as OpenSea or Rarible. This experiment revealed that the majority of NFTs do not actually store the media files (images, GIFs, videos) on the blockchain. Instead, the blockchain records a token linked to a file on a conventional server, which the owner can modify or delete at any time. Consequently, NFT buyers do not acquire the digital object itself but merely a record in a distributed ledger that references the object. True ownership of the asset remains with the creator or the server owner where the asset is hosted, challenging the very concept of immutable ownership rights that NFT proponents advocate.
Centralized Points of Failure
Marlinspike’s criticisms have been supported by real-world events. In August 2022, when U.S. authorities sanctioned Tornado Cash, services like Infura and Alchemy promptly blocked access to the mixer’s smart contracts. This incident highlighted the reliance of many Web3 projects on centralized service providers, who are obligated to adhere to regulatory requirements. Ethereum co-founder Vitalik Buterin acknowledged the validity of these concerns, recognizing the issue of dependency on centralized APIs; however, he views it as a transient challenge. He believes that the advent of “light” clients, which do not necessitate downloading the entire blockchain, will eventually empower users to engage with the network directly.
The MobileCoin Paradox
Marlinspike’s stance may seem paradoxical since the Signal messenger integrated payments using the MobileCoin (MOB) cryptocurrency. However, this does not create a direct conflict. His critique targets the Web3 ecosystem and its misleading claims of decentralization, not the underlying cryptographic or blockchain technologies. MobileCoin emphasizes transaction privacy, resonating with Signal’s core philosophy. Marlinspike differentiates between the technology itself and its marketed image. While he employs cryptographic tools for specific purposes, he dismisses the idea that the current form of Web3 can fundamentally alter the internet. In early 2022, he stepped down as CEO of Signal to concentrate on his research, urging the industry to confront the reality of existing infrastructure challenges.
