What is secp256k1, is it the curve that is always used
Indeed the elliptic curve used in Bitcoin is secp256k1 which is the curve defined using a=0 and b=7 in your equation mod p. But other curves are used for other use cases (maybe other cryptocur...

Note that the questions should be about bitcoin, and therefore, so are the answers. Any other cryptocurrency MetaMask supports might not have the same procedure for generating private keys.

I'm trying to sign a segwit transaction in rust-bitcoin. To start with, my transaction setup looks as follows:
let previous_output = OutPoint::new(Txid::from_hex("991ab2b13f6bc6c13002d79d5e9775626a5e7328e14cd16837d50d1cc637dc6a").un...

In SigVersion::TAPROOT mode, there is no script to speak of, so the script interpreter is never invoked with it. See line 417 where this is asserted.

The data between the brackets is the count of transactions and most of the first coinbase transaction.
The brackets are positioned incorrectly.
That is bitcoin block 170 with Block ID 00000000d1145790a8694403d4063f323d499e655c83426834d4ce2f8dd4a2ee...
