If we were to go out of business, we&#39;d aim to give 6 months&#39; notice so customers can sweep their bitcoin. After that, they’d need new arrangements to manage inheritance. If you’re using Bitkey and see us go out of business, you could move your funds to another wallet.<br/><br/>If you&#39;re concerned about Block going out of business before your beneficiary completes a claim, consider setting up a backup method. You can add their fingerprint to your Bitkey and share a copy of your Emergency Access Kit to ensure they have access to your funds if needed. 2025-03-06T19:33:04Z https://yabu.me/nevent1qqsv4l9appmjfk37q4qqkfdqad062jwr2c3p42040pf6x258sgqy4lszyruecchrnc846umlm9hf5elghdrwpegvvzpzc57g0852r6e7pakqwgs2s8s In reply to <a href='/nevent1qqsqgnhtdv7qnw6ueazav254x5hperexuq7q4hpxhdwx2ssu9krenhgna20g0'>nevent1q…20g0</a><br/>_________________________<br/><br/>As part of the inheritance protocol, your beneficiary must store a decryption key to access an encrypted version of your mobile key stored by Block. They need their own Bitkey wallet (app + hardware) to securely store this information long-term and benefit from our recovery protections. Ultimately this is a safety-focused choice in our design - storing keys long-term is hard, and this protocol is based on your beneficiary having a key, not on their government ID or anything like that. And I’ll look into where we might be able to clarify this more/earlier. 2025-03-03T15:37:36Z https://yabu.me/nevent1qqsg6872p2camld2lwjm8n92hrj5pwr0s9qgh8hv5lhctsglwzyegpczyruecchrnc846umlm9hf5elghdrwpegvvzpzc57g0852r6e7pakqwacmrue In reply to <a href='/nevent1qqszpwh2qyq3a9x9m4n77aa04njczju66ndk6nj0pzagfkellje44eqy9qg8g'>nevent1q…qg8g</a><br/>_________________________<br/><br/><a href="https://github.com/rust-bitcoin/rust-bitcoin/blob/162094322fc75c92d1241f2afd4514131683856d/bitcoin/src/crypto/key.rs#L413">https://github.com/rust-bitcoin/rust-bitcoin/blob/162094322fc75c92d1241f2afd4514131683856d/bitcoin/src/crypto/key.rs#L413</a> (for mobile and server) &amp; <a href="https://github.com/proto-at-block/bitkey/blob/main/firmware/lib/crypto/src/ecc.c#L51">https://github.com/proto-at-block/bitkey/blob/main/firmware/lib/crypto/src/ecc.c#L51</a> (for firmware)<br/><br/>hope that helps! 2024-03-04T23:29:10Z https://yabu.me/nevent1qqs8zns0rqru4ysc5r5tlqaxdcjqaafd7hmgj59l84dpndfc2udgltgzyruecchrnc846umlm9hf5elghdrwpegvvzpzc57g0852r6e7pakqwzqt0kx Curious how #bitkey will help people stay in control of their funds when they lose part of their wallet?

Bitkey hardware ships with a key (not the one used for signing transactions) that can be used to sign messages and which Bitkey servers can verify. If a compromised phone attempts to modify what the hardware has signed, the server would know they&#39;ve been tampered with and would be able to surface that to the user via a channel like email.<br/><br/>On (2): if the Bitkey servers that communicate the addresses or transaction details to you in the proposed solution were compromised, what they show/send you wouldn&#39;t match your phone&#39;s screen. 2023-05-18T17:05:18Z https://yabu.me/nevent1qqswze5x2q9wc7pglncwaeupust40j6a4t5nd87fkvlx0j97xr8g9dqzyruecchrnc846umlm9hf5elghdrwpegvvzpzc57g0852r6e7pakqw30p2rx In reply to <a href='/nevent1qqsyts0yc8wqz8m9jnju3ptndan47f695lve0a6avdusywc8uz3xp5stawhu9'>nevent1q…whu9</a><br/>_________________________<br/><br/>Not 100% sure I understand your setup, but seems like probably one of these:<br/><br/>If it’s bluewallet on your phone plus Ledger: If your phone is sufficiently compromised, you can’t trust the address shown in bluewallet, or the QR code you’re scanning..<br/><br/>If it’s desktop plus bluewallet on your phone: if your desktop is sufficiently compromised, you can’t trust the address there, or a QR code scanned from there… 2023-05-17T20:33:10Z https://yabu.me/nevent1qqsxw3742vtkc9a2c8zhgcfwcmr7ch4yukpk3jefneugz368cuwwpvgzyruecchrnc846umlm9hf5elghdrwpegvvzpzc57g0852r6e7pakqw7x9ffn In reply to <a href='/nevent1qqsqfxynemv720plxnd8cd6zy674887qp58l63els86hzw3a22sndrqd904yh'>nevent1q…04yh</a><br/>_________________________<br/><br/>What do you usually compare it against?
