Blockchain Regulation Matrix
The Blockchain Regulation Matrix (BRM) establishes a framework outlining the concerns of regulating the blockchain from both the government and the consumer perspective, and in doing so, provides a pragmatic and clear approach to Web3 regulation. The BRM outlines regulation aspects of the blockchain by viewing it as a blockchain stack in many layers starting with the electricity physically supporting the blockchain at the base layer, all the way to the process of offloading crypto to fiat currency. With centralization and decentralization on either side of the matrix, the primary objective of the BRM is to understand where and how regulation of the blockchain should be developed specific to each layer.
Beginning with the electricty supporting the blockchain, as you hover over the images of each row, you'll see the specifics for that topic within that layer. The left side refers to projects that are centralized, while the right side refers to projects that are decentralized. For example, if there was an organization or business that wanted to provide electricity to miners in their area, that would be a centralized project. However, if there was a solar farm operating as a DAO that wanted to provide electricity to miners, that could be a decentralized project.
There are two illustrations of the Blockchain Regulation Matrix below, a short-form immediately below and a long-form afterwards.

Fiat Onboarding / Offboarding Accesscentralized
This row applies to protocols providing users access to onboard and offboard between fiat and crypto.
RegulatedMSB/MTL and MiCA regimes plus GENIUS rails make ramps the most enforced perimeter in crypto.
Government Concerns
- Fiat ramps are the primary AML/KYC chokepoint between banking and crypto
- Unlicensed money transmission through informal ramp operators
- Tax visibility at the exact moment crypto converts to fiat
Consumer Risks
- Exposure to potential legal consequences for non-compliant or anonymous transactions
- Risks associated with offloading blockchain assets to fiat without proper documentation
- Lack of investor protections and due diligence when converting assets to fiat
- Potential vulnerability to scams or fraudulent intermediaries operating in the fiat-crypto space
Cons to over-regulation
- Imposing high compliance costs and barriers for new entrants
- Slowing down the development of user-friendly and efficient fiat onboarding/offboarding solutions
- Potential hindrance to financial inclusion due to stringent regulations
Cons to lack of regulation
- Lack of standardized security and quality practices in fiat-crypto intermediaries
- Vulnerability to fraudulent schemes targeting users seeking fiat access
- Difficulty in addressing cross-border disputes and regulatory challenges
- Potential exposure to money laundering and other illicit activities
- Not ensuring a fair competitive landscape
Does blockchain technology currently exist to fulfill these obligations, and if so, what is it?
- Travel-rule messaging networks moving originator data between regulated ramps
- Chain-analytics screening at the ramp — the practical enforcement point for the whole stack
- Regulated stablecoin rails (post-GENIUS) giving banks a compliant on/off-ramp instrument
Current regulatory landscape
- enactedFinCEN MSB registration + state MTLs — US, 2013–. The longest-standing crypto regulation: ramps are money transmitters, full stop, since the 2013 FinCEN guidance.
- enactedGENIUS Act — US, 2025. Licensed payment stablecoins give banks and fintechs a clear, regulated bridge asset between fiat and crypto.
- guidanceFederal banking agencies withdraw restrictive crypto guidance — US, 2025. Fed, FDIC, and OCC rescinded the notification/pre-approval regime behind debanking; OCC reaffirmed custody authority.
- enactedMiCA CASP fiat-exchange services — EU, 2024. Fiat-crypto exchange is a licensed CASP activity with passporting across member states.
Notable incidents
- FTX/Alameda bank-access fraud (2022) — Customer fiat routed through misrepresented bank accounts — the on/off-ramp was where the fraud physically lived.
- Debanking wave ('Chokepoint 2.0') (2023–25) — Crypto firms and founders lost banking access industry-wide; by 2025 the restrictive supervisory guidance behind it was withdrawn.
