SEC Commissioner Hester Peirce recently issued a warning that layer-2 blockchains with centralized matching engines may need to comply with exchange registration requirements. Peirce emphasized the importance of regulatory protection for truly decentralized protocols during an interview on The Gwart Show.
Peirce highlighted the distinction between immutable code running on decentralized networks and centralized entities utilizing blockchain technology for trading purposes. According to her, decentralized protocols cannot be owned as they are sets of rules that are available for anyone to use.
However, the introduction of layer-2 solutions has added complexity to regulatory considerations. These solutions often centralize transaction ordering to address Maximum Extractable Value (MEV) issues. This departure from the traditional distributed node architecture of blockchain networks can raise concerns about centralized control over transaction sequencing.
Peirce pointed out that if a matching engine is controlled by a single entity, it resembles an exchange and may trigger exchange registration requirements. While acknowledging the benefits of centralized sequencers in terms of retail execution, she emphasized the need to avoid imposing exchange registration obligations on truly decentralized protocols.
The SEC is closely monitoring MEV solutions but Peirce expressed a preference for allowing the community to develop solutions before regulatory intervention. She believes that developers should be protected from registration requirements when writing code, while centralized intermediaries should adhere to existing regulatory frameworks.
Peirce’s regulatory approach is based on principles that differentiate between autonomous code and entities using code for regulated activities. She advocates for a regulatory framework that provides a safe harbor for truly decentralized protocols while subjecting layer-2 chains with centralized control mechanisms to traditional intermediary oversight.
As the tokenization of traditional securities increases, operators of layer-2 chains must assess whether their centralized components trigger exchange registration obligations, especially when processing securities transactions through controlled matching engines.
In conclusion, Peirce’s regulatory philosophy aims to strike a balance between fostering innovation and protecting investors. By distinguishing between levels of centralization rather than technology type, regulatory requirements can be tailored to ensure compliance while promoting technological advancements in the crypto space.
