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 Layerdecentralized
This row applies only to the layer of the blockchain processing the transactions before they are permanently settled on the blockchain.
ContestedPrivacy tooling and P2P transfers sit in live legal conflict: the Tornado cycle, the mixing NPRM, and the broker-rule repeal.
Government Concerns
- Not being able to remediate theft or crime within their jurisdiction
- Not being able to identify the criminal(s) behind the the exploits or scams
- Fair transaction processes during times of increased activity
- Mixers and privacy tools erasing the trace investigators rely on
Consumer Risks
- Sandwich and front-running bots extracting value from visible pending transactions
- No intermediary exists who can reverse a mistaken or fraudulent transfer
- Fee spikes during congestion pricing out small users
Cons to over-regulation
- Identity mandates on every peer-to-peer transfer are unenforceable against software and push activity into opaque channels
- Criminalizing privacy tooling outlaws lawful financial privacy along with laundering
Cons to lack of regulation
- Drainer and scam proceeds wash through unregulated paths while victims lack any recourse process
- Manipulation of transaction ordering (MEV) operates with no market-conduct rules
Does blockchain technology currently exist to fulfill these obligations, and if so, what is it?
- Encrypted mempools and private order flow blunting front-running
- View keys and zero-knowledge proofs enabling selective disclosure to auditors without public exposure
- Payment channels and rollups making small peer-to-peer transfers economically viable
Current regulatory landscape
- repealedIRS DeFi broker rule repeal (CRA) — US, 2025. Congress repealed the rule extending broker reporting to DeFi front-ends — the first crypto rule undone by the Congressional Review Act.
- proposedFinCEN mixing transactions NPRM — US, 2023. Would designate international convertible-virtual-currency mixing as a primary money-laundering concern with recordkeeping duties.
- rulingVan Loon v. Treasury / Tornado delisting — US, 2024–25. Immutable privacy contracts held outside sanctions authority; OFAC removed the designation in 2025.
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.
