Re: [bitcoin-dev] Deterministic Entropy From BIP32 Keychains
I have opened a BIP PR at https://github.com/bitcoin/bips/pull/910 and also created a Python library with test vectors referenced in the BIP text. I am still unsure if I should or shouldnt split the BIP's "Applications" into a separate BIP or leave in the current BIP. ‐‐‐ Original Message ‐‐‐ On Monday, April 6, 2020 5:36 PM, Rodolfo Novak wrote: > Hello, > > We are planning on implementing the Deterministic Entropy From BIP32 > Keychains BIP on Coldcard. > > Is there a BIP number planned to be assigned and is there any review of this > BIP yet? > > Regards, > > ℝ. > > Rodolfo Novak || Coinkite Inc. || GPG: B444CDDA ___ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
Re: [bitcoin-dev] Deterministic Entropy From BIP32 Keychains
Yes, I plan to submit as a BIP. I was just letting it sit for a while for others to consider. I was also considering to split the BIP into two. One for the the entropy derivation, and the Applications section would be another BIP. This would be akin to how BIP32 is the basis for derivation schemes like BIP39, and BIP44, BIP49 etc. Ethan ‐‐‐ Original Message ‐‐‐ On Tuesday, April 7, 2020 1:36 AM, Rodolfo Novak wrote: > Hello, > > We are planning on implementing the Deterministic Entropy From BIP32 > Keychains BIP on Coldcard. > > Is there a BIP number planned to be assigned and is there any review of this > BIP yet? > > Regards, > > ℝ. > > Rodolfo Novak || Coinkite Inc. || GPG: B444CDDA ___ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
Re: [bitcoin-dev] Deterministic Entropy From BIP32 Keychains
Although I believe that there needs to be a review by a cryptographic engineering expert (ideally Pieter Wuille, who may have to hold his nose to give it a pragmatic review) and I believe such a review will likely some suggest some improvements, I do think something in this area should be done. For instance with the offline tool #LetheKit https://github.com/BlockchainCommons/bc-lethe-kit, you could go to your vault, input your BIP39 from an offline titanium key or SLIP39 Shamir shards, and then derive a child key in BIP39 form that can be delivered via QR from the air-gapped LetheKit to another device you take away. — Christopher Allen ___ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
Re: [bitcoin-dev] Deterministic Entropy From BIP32 Keychains
I looked at it and consider the crypto choices reasonable and reusing existing bitcoin dependencies in library crypto building blocks mostly. For myself i think the use-case of having an offline seed manager that can be backed up once, and support multiple wallets, including ones created after the backup improves a practical and under-addressed problem for many users and businesses. The fact that the interface between an offline seed manager and a hardware or software wallet can be a bip39 mnemonic seed is convenient and an improvement over using custom derivation paths for practical use given the complexity of custom paths and variable support for them in wallets.

[bitcoin-dev] Deterministic Entropy From BIP32 Keychains
Hello, We are planning on implementing the [Deterministic Entropy From BIP32 Keychains](https://gist.github.com/ethankosakovsky/268c52f018b94bea29a6e809381c05d6) BIP on Coldcard. Is there a BIP number planned to be assigned and is there any review of this BIP yet? Regards, ℝ.
