The Hinman Speech: Sufficient Decentralization and Its Regulatory Legacy

On June 14, 2018, SEC Director of Corporation Finance William Hinman delivered a speech at the Yahoo Finance All Markets Summit that introduced the concept of “sufficient decentralization” into the digital asset regulatory lexicon. Hinman suggested that Ethereum — which had launched through a token sale that likely constituted an unregistered securities offering — had evolved to a point where its current offers and sales of ETH were not securities transactions. The speech generated immediate controversy and has been cited in virtually every significant digital asset litigation since, including the Ripple Labs case (settled August 2025 for $125 million, with the SEC withdrawing its appeal) and the Coinbase case (dismissed with prejudice February 27, 2025, $0 penalties). Hinman’s concept has been both embraced and challenged: Chairman Atkins’ November 12, 2025 Project Crypto and the March 2026 SEC-CFTC joint token taxonomy guidance move toward formal classification frameworks that may supersede the informal “sufficient decentralization” standard, with Atkins stating that most crypto assets should not be considered securities outright.

The Core Thesis

Hinman’s argument rested on a functional analysis of the Howey test. He posited that when a network becomes “sufficiently decentralized” — meaning no central party’s efforts are the primary driver of value — the “efforts of others” prong of Howey is no longer satisfied, and current transactions in the token cease to be securities transactions.

Key passages from the speech:

“If the network on which the token or coin is to function is sufficiently decentralized — where purchasers would no longer reasonably expect a person or group to carry out essential managerial or entrepreneurial efforts — the assets may not represent an investment contract.”

Hinman explicitly applied this framework to Bitcoin and Ethereum: “Putting aside the fundraising that accompanied the creation of Ether, based on my understanding of the present state of Ether, the Ethereum network, and its decentralized structure, current offers and sales of Ether are not securities transactions.”

This statement — that a token initially sold as a security could evolve into a non-security — introduced temporal dynamics into securities classification that the SEC Framework later incorporated but never fully resolved.

Legal Status of the Speech

The Hinman speech is a staff opinion, not an SEC rule, regulation, or formal guidance. Hinman explicitly disclaimed Commission authority: “These are my own views, not necessarily those of the Commission, the Commissioners, or other members of the staff.”

Despite this disclaimer, the speech has been treated as quasi-authoritative guidance by courts, practitioners, and market participants. Its influence derives from Hinman’s position as Director of Corporation Finance — the division responsible for securities registration and the primary gatekeeper for public offerings.

In the Ripple litigation, the speech became a central exhibit. Ripple obtained internal SEC communications related to the speech through FOIA litigation, revealing that Hinman had been advised by SEC ethics counsel that the speech might create conflicts of interest given his prior employment at a law firm representing Ethereum-related entities. These internal documents were ultimately unsealed by Judge Torres, fueling criticism of the SEC’s regulatory approach.

Defining “Sufficient Decentralization”

Neither Hinman nor any subsequent SEC official has provided quantitative criteria for “sufficient decentralization.” The concept remains functionally undefined, creating uncertainty for every token project that seeks to transition from security to non-security status.

Practitioners have proposed various metrics, none officially endorsed:

Nakamoto Coefficient. Measuring the minimum number of entities needed to compromise a network’s consensus mechanism. A higher coefficient suggests greater decentralization, though the threshold for “sufficient” remains undefined.

Token distribution. Examining whether any single entity or coordinated group controls a significant percentage of token supply. Projects where founders, development teams, or venture investors hold 30%+ of supply face stronger arguments that centralized efforts drive value.

Governance distribution. Analyzing whether protocol governance decisions are effectively controlled by a small group or distributed among diverse token holders. DAO governance with concentrated voting power may not satisfy decentralization requirements.

Development dependency. Assessing whether the network would continue to function if the founding development team ceased operations. Networks with multiple independent client implementations, decentralized upgrade mechanisms, and broad developer ecosystems present stronger decentralization arguments.

Impact on Token Design

The Hinman speech directly influenced how projects structure their token launches and network development. The concept of “progressive decentralization” — launching with centralized control and gradually distributing authority — became the dominant design pattern for token projects after 2018.

Projects following this pattern typically: (1) launch under a centralized development team, (2) issue tokens through a compliant offering under Reg D or Reg S, (3) gradually decentralize governance and development over 2-5 years, and (4) claim non-security status once “sufficient decentralization” is achieved.

The fundamental problem with this approach is the absence of an official mechanism for confirming the transition. No SEC process exists for a token issuer to apply for a determination that its token has become sufficiently decentralized. The issuer must simply make a judgment call — and accept the litigation risk if the SEC disagrees.

The Hinman Speech in Litigation

The Hinman speech has been invoked as a defense or contextual reference in virtually every significant digital asset enforcement case since 2018:

SEC v. Ripple Labs

In the Ripple litigation, the speech became a central exhibit. Ripple’s defense argued that the Hinman speech created a reasonable expectation that XRP — like Ethereum — could transition from a security to a non-security through sufficient decentralization. Judge Torres’s July 2023 summary judgment ruling partially adopted this reasoning, finding that programmatic sales of XRP on exchanges (where buyers did not know they were purchasing from Ripple) did not satisfy the Howey test’s “efforts of others” prong.

Ripple obtained internal SEC communications related to the speech through FOIA litigation, revealing that Hinman had been advised by SEC ethics counsel that the speech might create conflicts of interest given his prior employment at Simpson Thacher, a law firm representing Ethereum-related entities. The internal documents showed that multiple SEC staff members provided feedback on draft versions of the speech, suggesting a more institutional process than Hinman’s personal disclaimer implied. These internal documents were ultimately unsealed by Judge Torres, fueling criticism of the SEC’s regulatory approach.

SEC v. LBRY

In SEC v. LBRY, the defendant argued that LBC tokens had achieved sufficient decentralization to fall outside securities classification under the Hinman framework. Judge Paul Barbadoro rejected this argument, finding that LBRY Inc. remained the primary driver of the LBRY network’s value through its ongoing development, marketing, and operational efforts. The ruling established that ongoing development activity by an identifiable team weighs heavily against a finding of sufficient decentralization, regardless of the network’s technical architecture.

SEC v. Terraform Labs

In the Terraform Labs action, the court declined to apply the Hinman framework, ruling that the decentralization analysis applies to the “efforts of others” prong of Howey but does not override a finding that purchasers had a reasonable expectation of profits. The court emphasized that decentralization of network infrastructure is distinct from decentralization of the economic enterprise — a token project can have decentralized validators while the founding team retains centralized control over marketing, treasury, and strategic direction.

Enforcement Implications

These cases collectively narrow the Hinman speech’s practical utility. Courts have been unwilling to find “sufficient decentralization” in any case where an identifiable development team continues to provide significant contributions to the network. This judicial skepticism means that the speech’s framework may apply only to truly mature networks like Bitcoin and (arguably) Ethereum — assets that most new token projects are unlikely to resemble within a three-year development period.

The FOIA Litigation and Internal Documents

The internal SEC documents related to the Hinman speech, obtained through FOIA litigation by Empower Oversight (and separately by Ripple Labs), revealed several important details about the speech’s development:

Multiple drafts reviewed. The speech went through at least five revisions between May and June 2018, with input from the Division of Corporation Finance, the Division of Trading and Markets, and the Office of the General Counsel. This inter-divisional review process suggests that the speech reflected a broader institutional view than Hinman’s personal disclaimer indicated.

Ethics concerns. SEC ethics officials raised concerns about Hinman’s prior relationship with Simpson Thacher, which represented entities in the Ethereum ecosystem. Internal emails showed that Hinman was advised to include the personal disclaimer and to avoid language that could be interpreted as providing a definitive regulatory determination about Ethereum’s status.

No formal vote. Despite the inter-divisional review, the speech was never submitted to the Commission for a formal vote. This procedural point — that the speech represents staff views rather than Commission action — has been central to the SEC’s position that the speech creates no binding regulatory precedent.

Post-Hinman Regulatory Evolution

Subsequent SEC leadership has distanced from the Hinman speech without formally repudiating it. Chairman Gensler’s public statements from 2021-2024 avoided the “sufficient decentralization” framework, instead emphasizing that most crypto tokens — regardless of their governance structure — qualify as securities under Howey.

The change in SEC leadership in 2025 has brought renewed attention to the decentralization framework, with acting chair Mark Uyeda and Commissioner Peirce signaling openness to principles-based approaches to token classification. The SEC Crypto Task Force has included token classification as a priority roundtable topic, with the Hinman speech serving as a starting point for discussions about whether to formalize the “sufficient decentralization” concept through rulemaking.

Commissioner Peirce’s Token Safe Harbor proposal directly builds on the Hinman framework, providing a structured three-year pathway for tokens to transition from security to non-security status through progressive decentralization. The safe harbor’s disclosure requirements and exit conditions operationalize the general principles Hinman articulated in 2018.

The Hinman speech’s legacy is a framework that influenced an entire industry’s design choices while remaining legally unenforceable and officially disavowed. For token issuers, the practical guidance remains: assume your token is a security until you have overwhelming evidence otherwise, and structure your compliance accordingly through registered offering exemptions and SEC-compliant market infrastructure.

Quantitative Decentralization Metrics in Practice

Despite the absence of official SEC criteria, the industry has developed informal quantitative benchmarks that legal practitioners use when advising token projects on decentralization assessments:

Token distribution thresholds. Securities lawyers commonly advise that no single entity or coordinated group should control more than 20% of the outstanding token supply — a threshold that aligns with the FIT21 Act’s proposed concentration test. Projects with founder allocations exceeding 30% face substantially higher litigation risk if the SEC challenges their non-security classification.

Validator and node distribution. For proof-of-stake networks, practitioners examine the number of independent validators and the concentration of staking power. Networks where the top 10 validators control more than 50% of staking power face stronger arguments that the network remains centralized. Bitcoin’s mining network, with thousands of independent miners across dozens of jurisdictions, represents the benchmark for decentralization — a standard that few newer networks approach.

Development contributor diversity. The number of independent development teams contributing to the protocol’s codebase serves as a proxy for development decentralization. Ethereum’s hundreds of independent contributors across multiple client implementations (Geth, Nethermind, Besu, Erigon) establish a high bar. Projects relying on a single development entity — even if the code is open source — face challenges claiming sufficient decentralization under the Hinman framework.

Revenue and funding independence. Whether the protocol generates sufficient fee revenue or has diversified funding sources to sustain development without the founding team’s treasury disbursements indicates economic decentralization. A network that would cease meaningful development if the foundation stopped funding contributors demonstrates ongoing reliance on a central entity.

The Hinman Speech and Token Project Structuring

The practical impact of the Hinman speech on token project legal structuring has been substantial. Major law firms advising blockchain projects routinely incorporate the speech’s framework into their compliance analyses and project design recommendations:

Foundation structures. Many token projects establish independent foundations (often in Switzerland, Singapore, or the Cayman Islands) to manage protocol development and treasury, separating the founding team from ongoing network operations. This structural choice directly reflects the Hinman speech’s emphasis on separating the “efforts of others” from token value creation.

Token lockup and vesting schedules. Projects design vesting schedules for founder and team tokens that align with decentralization timelines — typically 3-5 years with cliff periods — to demonstrate that insiders do not retain disproportionate control over supply during the critical early development period.

Governance transition roadmaps. Sophisticated projects publish detailed governance transition plans that map the transfer of protocol decision-making authority from the founding team to token holder governance over a defined timeline, creating a documented record of progressive decentralization.
