Did any 2009 Bitcoin service generate multi-word passphrases?

I am trying to identify a Bitcoin-related service or wallet that I remember using around 2009. I understand that modern mnemonic recovery seeds (such as BIP39) did not exist in 2009, and I am not claiming that this was a modern seed phrase. My recollection is the following: I was introduced to Bitcoin by a friend. I created a new email account specifically for this. I registered on a website with an email address and password. I bought Bitcoin for a small amount of euros. My recollection is that payment was made by bank transfer from a German bank account. Afterward I could see a Bitcoin balance associated with my account on the website. I was advised to move the bitcoins to a wallet so that I would still have access to them if the website disappeared. I did not install wallet software. I remember doing this in the browser. During this process, the system generated a number of apparently random words for me. I understood these words at the time as a password/passphrase and...

How to Sign a Musig with Bitcoin Core

Today I was back at trying to sign a transaction spending a musig UTXO in Bitcoin Core. Last time around, Pieter W. gave me two pieces of advice. Use PSBTs, as they're more likely to work on modern stuff like Musig than raw transactions. He asked how I was generating my private/public keys, which made me realize I'd probably calculated my pubkey incorrectly. So today I took a new swing, using the same methodology I use for signing regular multisigs in Bitcoin Core, but now I can't get the PSBT to process correctly. I. Capturing the Individual Keys I used the simplest method possible to generate a musig address: grab addresses from two different wallets and capture their pubkeys. (The private keys should then be sitting in those wallets.) Here's the address & pubkey capture: musigaddress1=$(bitcoin-cli -rpcwallet=musig1 getnewaddress) musigaddress2=$(bitcoin-cli -rpcwallet=musig2 getnewaddress) musigpubkey1=$(bitcoin-cli -rpcwallet=musig1 -name...

What changed in Bitcoin P2P protocol version 70017 compared to 70016?

I recently installed Bitcoin Core 32.0rc2 on one of my nodes and noticed that the reported P2P protocol version changed from 70016 to 70017. I remember 70016 being used for quite a long time, so I was curious what exactly triggered the protocol version bump. What changed in protocol version 70017 compared to 70016? Also, how does a 70017 node behave when connected to a peer that only supports 70016? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/Pz5vkwX via IFTTT

Why does Bitcoin use both a transaction ID and a witness transaction ID?

While learning Bitcoin transactions and SegWit, I came across the distinction between the traditional transaction ID (txid) and the witness transaction ID (wtxid). I understand that the txid is the double-SHA256 hash of the serialized transaction excluding the witness data. andd wtxid commits to the transaction including the witness data. SegWit introdduced wtxid partly to solve transaction malleability issues. What I am having trouble understanding is why Bitcoin needs both identifiers instead of simply replacing txid with a hash that always commits to the witness data. For example, suppose a SegWit transaction has the same inputs and outputs but different witness data. The txid remains unchanged while the wtxid changes. I would like to understand the design consequences of this distinction... What specifically would break if Bitcoin used only wtxid everywhere? Why do transaction inputs continue to refer to previous outputs using txid:vout rather than wtxid:vout? How doe...
