So these attempts by governments to introduce online age verification requirements, are these going to use zero knowledge proofs? Are they trying to sell this by floating the idea that you can prove your age while still remaining "anonymous" in some sense or another? From what I'm reading, it seems that zk proofs won't really work to achieve this in any truly meaningful way. See for example this for a critique:

ZKPs are often advanced as a technical remedy, promising privacy-preserving attestations of age or eligibility. Yet their deployment in practice ex...

Does anybody have any insights into what's going on here?

Inkan separates your identity from your signing key. If the signing key is leaked or lost, revoke it. Switch to a new one. Same identity. Same followers. New signing key. The prototype is here:

Inkanでは、アイデンティティと署名用キーを分けて扱えます。 署名用キーが漏れたり失われたりしても、そのキーを取り消して、新しいキーに切り替えられます。 アイデンティティとフォロワーはそのまま。 よろしければ、プロトタイプを少し覗いてみてください。

InkanにNIP-46対応を追加しました。 Amberで試したところ、ちゃんと動いているみたいです。 これで、リモート署名を使いつつ、署名用キーが漏れたり失われたりした場合でも、新しいキーに切り替えられるようになります。 アイデンティティとフォロワーはそのまま。

Just realized that I can use NIP-7 with Firefox on my cell phone. I had no idea.

I've added NIP-46 to Inkan. I've tested on Amber and it seems to work. This means you can now have a remote signing setup plus the ability to replace your signing key if it ever gets lost or leaked, while maintaining your identity and your followers.

今の仕組みだと、オンライン上のアイデンティティは、ほとんど秘密鍵そのものになってしまいます。 その鍵が漏れたり失われたりすると、そのアイデンティティも終わってしまう。 Inkanはそこを変えようとしています。 マスターキーはコールドストレージに置いたまま、普段の投稿や署名には別の署名用キーを使います。 もし署名用キーが漏れたり失われたりしても、マスターキーで取り消して、新しいキーに委任できます。 アイデンティティもフォロワーもそのまま。署名用キーだけ新しくできます。 プロトタイプはこちらです：

I made a bootable live USB image that has the Inkan Management Utility pre-installed. This is meant to provide an airgapped environment for signing delegations and revocations of signing authority between key pairs, and for identity creation. The OS is expected to be amnesic across reboots and networking is disabled. I added QR codes to conveniently transfer keys and signed declarations to an online system. You can also configure persistent storage to keep the keys that secure your identity right on that USB.
