What do you think of the guide? I browsed a lot of it and think it brings up some good points and explains certain aspects of multi sig well. However, the paper wallet/keystone choices seem non-ideal and overall like it may be out of date/not very well maintained. Also, seems like it would take a long time to set up.

Thank you for that guide!

I think it’s a good option, however I’m not sure I’m qualified enough to suggest a particular multi sig setup. It’s hard for me to weigh trade offs, in this case of locking into a single vendor. I have personally found more peace in using a company like Casa or Unchained, who are experts at making those types of decisions and make it super easy to setup

Chapter 5 of learning bitcoin from the command line is about transactions that get stuck, usually because too low of a fee. I’m going to do a side tangent today of learning as much as I can about tx replacement, rather than blowing through the chapter.

2023-06-26 02:50:22

Worked through the first 4 chapters of Learning bitcoin from the command line (https://github.com/BlockchainCommons/Learning-Bitcoin-from-the-Command-Line). I couldn’t figure out setting up a node on Linode, so just ram bitcoin locally on regtest. Overall, the chapters were good and I learned a bunch, though were some parts that were a little rough and out of date. Keeping guides/docs up to date is super hard, especially when they are for free. I think there will be a large bitcoin technical teaching industry in 5-10 years

In theory you can. For me personally, I think it’s better to just get 3 new devices and sweep all the bitcoin from your single sig to the new multi sig setup. It keeps things simple. Since a multi sig setup is likely securing a large amount of funds, the cost of an additional device should be relatively small

My biggest question was how OP_CHECKMULTISIG matches up the provided signatures with the corresponding public keys. The answer is that it just loops through the public keys and tries to verify the signatures! In my mind I thought there would be some type of mapping. It was also surprising to me that even if you have a threshold of valid signatures, they need to be in the right order.
These resources together did a great job explained the nitty gritty:

TBH it’s a little hard for me to evaluate how big of an issue it is for Muun users. It’s quite technical, multi-faceted and may? still playing out. Sorry I can’t provide a better explanation.

The lightning network is hard to make simple user interface for. A lot of wallets are experimenting with different models. Muun chose to pay for lightning invoices with onchain transactions at the time of payment. The problem is that in high fee environments, like we have been in recently, you pay ridiculously high fees for lightning payments. That’s my high level understanding. One thing to note with phoenix, you should try to make your first transaction pretty large because that’s what will create your lightning channel and so you will have to pay on-chain fees for it

The miners fee actually gets included in the coinbase tx of each block! For a normal tx you can calculate the fee by subtracting the sum of the outputs from the sum of the inputs. It’s pretty cool that the fee is implicit rather than an explicit utxo. It saves a lot of space on the chain

Hey #[1]! I’m certainly not an expert but I found these two good posts on how to calculate virtual size for a transaction and did it for the situation you mentioned.
https://bitcoin.stackexchange.com/questions/92689/how-is-the-size-of-a-bitcoin-transaction-calculated
https://bitcoin.stackexchange.com/questions/92587/calculate-transaction-fee-for-external-addresses-which-doesnt-belong-to-my-loca/92600#92600
All transactions will have at least 40 weight units
40 (weight unit of constant* fields in a transaction: version 16, num inputs 4, num outputs 4, locktime 16)
+
2 (this is a segwit tx so need to add marker and flag)
+
(3 * 272) (3 p2wpkh inputs)
+
(2 * 124) (1 p2wpkh output)
= 1106 WU (weight units)
1106 / 4 = 276.5
Need to round this up so it equals = 277vB

Yep! So I'll just focus on p2wpkh. The locking script for those UTXOs looks like this: 00 14 <20 byte pubKeyHash>. Old nodes interpret it as, push an empty array to the stack then push 20 bytes (convert 16 from hex to decimal) to the stack. They think that anybody can spend this UTXO because it doesn't have any signature checks! Even a signature field with just 00 would be valid according to their rules. If old nodes could think like a human, I like to picture them looking at the current blockchain and being so confused as to why all of these transactions are happening without signatures. In reality, most of the nodes are upgraded to segwit. These segwit nodes require an additional field on the transaction called a witness (old nodes never even see this). When a segwit node verifies the same transaction, it will verify that the witness field contains a public key that hashes to correct value and has valid signature.
