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.

Transaction Layercentralized
This row applies only to the layer of the blockchain processing the transactions before they are permanently settled on the blockchain.
RegulatedTravel-rule, the EU TFR, and broker reporting comprehensively cover intermediary transactions.
Government Concerns
- Ensuring traceability and transparency of transactions
- Preventing illegal activities such as money laundering and fraud
- Addressing cross-border transaction challenges and regulatory compliance
- An anonymous public ledger inhibits appropriate recordkeeping
Consumer Risks
- Exposure to potential transaction delays or fees
- Privacy concerns related to transaction history being publicly accessible
- Risk of inaccurate or irreversible transactions
Cons to over-regulation
- Stifling innovation and experimentation with new transaction models
- Restricting financial inclusion by imposing excessive compliance requirements
- Hampering the usability and efficiency of blockchain transactions
Cons to lack of regulation
- Increased susceptibility to fraudulent or malicious transactions
- Difficulty in resolving disputes related to unauthorized or erroneous transactions
- Lack of consumer protection and accountability
Does blockchain technology currently exist to fulfill these obligations, and if so, what is it?
- Blockchain analytics have made public-ledger tracing routine for investigators — the ledger is more traceable than cash
- Travel-rule messaging networks (TRUST model) moving originator data between regulated intermediaries
- Layer-2 rollups cutting fees while inheriting base-layer settlement security
Current regulatory landscape
- guidanceFinCEN Travel Rule application to CVC — US, 2019. Money-transmitter originator/beneficiary rules applied to virtual-currency intermediaries above $3,000.
- enactedEU Transfer of Funds Regulation (recast) — EU, 2024. No-threshold originator/beneficiary data for CASP transfers; verification duties for self-hosted wallets above €1,000.
- enactedIRS custodial broker reporting (Form 1099-DA) — US, 2024. Custodial brokers report digital-asset sales from tax year 2025 — transaction-level tax visibility at regulated intermediaries.
Notable incidents
- Tornado Cash sanctions cycle (2022–25) — OFAC sanctioned an immutable mixer; the Fifth Circuit's Van Loon ruling (2024) held immutable contracts aren't sanctionable property, and the listing was withdrawn in 2025.
- Bybit hack laundering flows (2025) — The $1.5B theft's rapid cross-chain laundering became a live stress test of exchange, bridge, and mixer chokepoints at the transaction layer.
