Over the last week, there’s been a lot of discussion about Canada ‘freezing’ digital currency accounts that are associated with the Canadian trucker’s Freedom Convoy. Amid the topical conversation, it should be stressed that decentralized cryptocurrencies like bitcoin and ethereum, cannot be frozen directly within the network. However, the Canadian government can flag specific digital currency addresses and take it even further, by asking centralized entities like crypto exchanges and payment processors to freeze the funds.

It is impossible to freeze a bitcoin (BTC) or ethereum (ETH) address and render it useless to the owner. The only way to do that is by using force or threats of imprisonment or death and ultimately obtaining a crypto owner’s private keys.
