You could be asked to sign a message provided to you by the government. That would be enough. It's interesting, because normally a bank/exchange would do that for you, but in this case, it's up to you to report which assets you own. The fact that it is possible is the interesting thing here.

> You could be asked to sign a message provided to you by the government. That would be enough. That would only link you to one particular address. Modern wallets are typically "hierarchical deterministic" as described in BIP32[1]. They generate new keys/addresses from a seed value as needed. To properly register such a wallet, you would have to provide the root public key from which all addresses can be derived (but not private keys).
