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 sche

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. Fo

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

[bitcoin-dev] Deterministic Entropy From BIP32 Keychains

2020-04-06 Thread Rodolfo Novak via bitcoin-dev
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. Rodolfo Novak
