script – Why are signatures totally different for inputs from the identical tackle in a single Bitcoin transaction?

I’ve been finding out Bitcoin transaction signatures and seen some fascinating patterns when analyzing transactions involving the identical tackle in numerous contexts. Listed here are my observations.

Case 1: Similar tackle, two totally different transactions (T1 and T2)

As anticipated, for 2 separate transactions originating from the similar tackle, I noticed the next witness information:

30450221008dbd2c3c33413a58d0217897daa9cfe75a7aaad3d80d915ed74dbfbc7dc70d43022034a8328a99065ff8f47acb9da4ce213ee6bf90448580cfd5129e36f39a985c3801 023b6bdc0869a329e9d0cb036257eff362aeab11512668090746bf31647a42039e

3045022100cc584f8b3c0a23d5531d1e46b15e10be7138409c46c04a16716af89ea8a653ec02202a1e364f7c2b0f4f6e995bf73b65a4ed86e5166f9c7544a397a6c38b8db4a43301 023b6bdc0869a329e9d0cb036257eff362aeab11512668090746bf31647a42039e

Right here, I assume/guess that:

1. The first hexadecimal string within the witness is the signature, and
2. The second hexadecimal string is the general public key.

As anticipated:

1. The signatures are totally different as a result of every signature is tied to the precise transaction.
2. The public key is identical because it corresponds to the tackle.

This is smart as a result of the signature era course of incorporates the transaction information (or its hash)…. however:

Case 2: A transaction (T3) with two inputs from the identical tackle

Once I analyzed a single transaction with two inputs, each originating from the similar tackle, I noticed the next witness information:

30450221008dbd2c3c33413a58d0217897daa9cfe75a7aaad3d80d915ed74dbfbc7dc70d43022034a8328a99065ff8f47acb9da4ce213ee6bf90448580cfd5129e36f39a985c3801
023b6bdc0869a329e9d0cb036257eff362aeab11512668090746bf31647a42039e

3045022100cc584f8b3c0a23d5531d1e46b15e10be7138409c46c04a16716af89ea8a653ec02202a1e364f7c2b0f4f6e995bf73b65a4ed86e5166f9c7544a397a6c38b8db4a43301
023b6bdc0869a329e9d0cb036257eff362aeab11512668090746bf31647a42039e

On this case:

1. The signatures are totally different, regardless that each inputs are from the identical tackle.
2. The public secret’s equivalent for each inputs, as anticipated.

This means that the signature isn’t for all the transaction however fairly for every enter individually. Plainly every enter indicators a particular “message”.

Questions:

1. Why are the signatures totally different for every enter inside the similar transaction?
2. Does this imply {that a} signature isn’t generated for all the transaction however fairly for every enter independently?
3. What precisely is being signed in every enter, and what function does UTXO play on this course of? Does the signature have a reference indirectly a SPECIFIC UTXO?
4. Why is the Witness information solely represented by hex binary? I could not discover any converter to “human” Script directions. Is there any?
5. So principally, is it right to say that, for a similar tackle, the locking script would be the similar, whereas the unlocking script (witness) will likely be totally different as a result of it depend upon the SPECIFIC SINGLE INPUT of a transaction?

Any clarification on this habits and the underlying mechanisms can be tremendously appreciated. Thanks!
