Re: [bitcoin-dev] Card Shuffle To Bitcoin Seed

It's not quite enough to just do SHA512, you missed out this condition (incredibly rare as it is): > In case IL is 0 or ≥n, the master key is invalid. Also I can't see how I would use this to seed a hardware wallet that requires a BIP39 seed as mentioned in your abstract. For both of those

Re: [bitcoin-dev] BIP39 seeds

> Using some algorithm to take some input and generate a bip39 phrase that you can use with any bip39 wallet sounds perfectly reasonable. I think any method that doesn't use real entropy, but some fake source of randomness, such as a book is asking to be hacked and so is not a reasonable idea.

Re: [bitcoin-dev] Transaction Merging (bip125 relaxation)

So, OP, in your scenario, you have 1 transaction in the mempool, A, then you want to spend the change before confirmation, so you broadcast a new transaction, B, which replaces A. > Because the size of the merged transaction is smaller than the original transactions, unless there is a

Re: [bitcoin-dev] BIP Proposal: Revised: UTPFOTIB - Use Transaction Priority For Ordering Transactions In Blocks

I don't see any modifications to the proposal that addresses the issue that miners will always be free to choose their own priority that a few people brought up before. I understand you think it's in the miners best long-term interest to follow these rules, but even if a miner agrees with you, if

Re: [bitcoin-dev] Suggestion to remove word from BIP39 English wordlist
