EU regulators just made a CRUCIAL call on blockchain miners/validators under MiCA – excluding them from market abuse oversight. 

Why? Forcing them to police transactions would break blockchain’s neutral infrastructure

BIG win for credible neutrality 🧵

Miners/validators prioritize transactions based on fees, not market manipulation. Their role is technical – securing networks, not financial intermediation. 

ESMA agreed: requiring them to flag suspicious activity would be like asking road builders to police drivers.

This preserves network neutrality & protects censorship resistance – core to crypto’s ethos. 

If validators had to judge transaction legitimacy, it’d create gatekeepers. 

MiCA rightly avoids politicizing blockchain’s base layer

Sanctions angle: While miners stay neutral, CASPs (exchanges) MUST monitor flows. MiCA still empowers regulators to freeze funds at the exchange level

Cypherpunk win all the same: infrastructure ≠ financial actors
