In the ever-expanding blockchain world, Ethereum has long stood out, providing the benchmark for its innovation, decentralization, community building, and security. Led by the Ethereum Foundation and a dedicated community of developers, investors, influencers, researchers, validators, and regular users, the ecosystem consistently remains at the forefront of blockchain and digital asset developments.
One of its defining characteristics is its ability to evolve and implement changes that improve some facet of its vast ecosystem, with many of these proposed changes coming from its community. The Merge and Fee Market Reform are just a couple of examples of Ethereum embracing and implementing community feedback.
On June 9, Ethereum community member Eugenio Reggianini published a proposal suggesting the use of a modular architecture to effectively provide data management and privacy. His consideration of this proposal is rooted in what many feel is the need for Ethereum to balance decentralization and compliance under the EU’s GDPR (General Data Protection Regulation) framework.
Reggianini wrote: “By pushing personal data to the edges (wallets and dApps), using off-chain storage with metadata-erasure, and splitting roles cryptographically, we can focus GDPR controller duties on a small set of entities, while the wider network becomes mere processors or falls out of scope.”
With a growing buzz around the tokenized real-world assets (RWAs) space and peak interest from traditional finance (TradFi) players, the elephant in the room is what this proposed reform could mean for institutional adoption. Compliance concerns and data privacy remain major hindrances that prevent banks and asset managers from engaging with siloed private chains.
Adi Ben-Ari, CEO and founder of Applied Blockchain, a blockchain development studio for enterprises, institutions, and RWA platforms, believes this proposal could be a boost for institutional adoption.
“A modular approach makes a lot of sense, and this is an interesting proposal that offers a potential path forward for European institutions seeking to interact with public chains without breaching privacy regulations. If successful, it could reduce the compliance burden for many participants in the ecosystem, without compromising user sovereignty,” he explained.
James Wo, Founder and CEO of DFG, a global blockchain and crypto investment firm that is particularly active in the Ethereum ecosystem, provides a perspective from a VC’s angle. Wo believes that this proposal makes Ethereum projects more attractive to investors and could drive “mainstream adoption and growth without regulatory headaches.”
Wo elaborates: “EU data compliance is critical as it unlocks bigger markets and builds user trust. Ethereum’s privacy proposals using ZK [zero knowledge], FHE [fully homomorphic encryption], or TEEs [trusted execution environment] strike a great balance, protecting user data while staying true to Web3’s decentralized ethos.”
There’s no denying that this proposal is ambitious, but it’s hard to argue against its technical coherence. For one, the proposal provides a path toward GDPR compatibility without compromising on decentralization or negating its permissionless nature.
However, the feasibility of this proposed initiative relies on full-stack PET integration, application discipline, and proactive cooperation with regulatory bodies. Furthermore, a great deal hinges on user behavior and the need for education around data privacy. If users don’t understand what constitutes personal data, are unsure how to avoid leaking it, or don’t opt for privacy-respecting apps and wallets, then PETs and a modular architecture won’t save Ethereum from the ire of regulators.
Ben-Ari reasons that if the proposal in its current form is adopted by the Ethereum community, it would reduce the friction and make enterprise and institutional adoption more likely. However, he notes that the PETs mentioned in the proposal come with tradeoffs.
“While FHE and ZK are powerful for anonymizing or obfuscating data on-chain, they often introduce high computational overhead and developer complexity, particularly when applied to real-time or high-throughput financial applications.”
He would go on to explain that Silent Data, a privacy-focused platform developed by Applied Blockchain, “leverages TEEs to strike a pragmatic balance between privacy, performance, and auditability. Silent Data enables real-time computation on sensitive data on-chain, without revealing the data itself and without impacting performance. This architecture meets GDPR requirements around data minimization and access control while preserving usability for institutions.”
The GDPR is notoriously stringent, and simply adopting a modular approach will present several challenges and risks. For Example, dApps and wallets will need to adopt PETs, and incomplete anonymization and possible enforcement inconsistencies will make navigating this transition tricky.
While Reggianini firmly believes in this approach, he also recognizes that the path to GDPR compliance “depends on widespread adoption of privacy-enhancing technologies and clear, collaborative governance.”
With increased legitimacy around blockchain and tokenized RWAs, it’s becoming clearer that regulatory compliance will need to be addressed. While any structural change to meet legal frameworks may be technically and socially painful, they are essential for the network’s long-term legitimacy, resilience, and real-world adoption.
