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

I’ve been finding out Bitcoin transaction signatures and observed some attention-grabbing patterns when analyzing transactions involving the identical handle in several contexts. Listed here are my observations.

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

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

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 particular transaction.
2. The public key is identical because it corresponds to the handle.

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

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

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

30450221008dbd2c3c33413a58d0217897daa9cfe75a7aaad3d80d915ed74dbfbc7dc70d43022034a8328a99065ff8f47acb9da4ce213ee6bf90448580cfd5129e36f39a985c3801
023b6bdc0869a329e9d0cb036257eff362aeab11512668090746bf31647a42039e

3045022100cc584f8b3c0a23d5531d1e46b15e10be7138409c46c04a16716af89ea8a653ec02202a1e364f7c2b0f4f6e995bf73b65a4ed86e5166f9c7544a397a6c38b8db4a43301
023b6bdc0869a329e9d0cb036257eff362aeab11512668090746bf31647a42039e

On this case:

1. The signatures are totally different, although each inputs are from the identical handle.
2. The public secret is an identical for each inputs, as anticipated.

This means that the signature will not be for all the transaction however somewhat 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 will not be generated for all the transaction however somewhat 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 not directly a SPECIFIC UTXO?
4. Why is the Witness knowledge solely represented by hex binary? I could not discover any converter to “human” Script directions. Is there any?
5. So mainly, is it appropriate to say that, for a similar handle, the locking script would be the similar, whereas the unlocking script (witness) will likely be totally different as a result of it rely upon the SPECIFIC SINGLE INPUT of a transaction?

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