This can be a transaction with three P2WPKH (native segwit v0 single-sig) inputs and a single P2WPKH output. For P2WPKH, the scriptPubKey (the locking script encoded in an output) accommodates a witness program that commits to the hash of a public key. The witness within the enter due to this fact reveals the corresponding pre-image of the hash within the type of the general public key (33 bytes) and offers the suitable signature of 71 or 72 bytes. As every enter should have a witness (if there may be no less than one segwit enter), there are three witnesses with these two objects every. For instance the witness for the primary enter (labeled as place 0) is proven within the following two traces of your knowledge:
Witness 0 0 71 010F0EC3631C1100B7C9646F5537BFE4E71244298800B25BC7ED01C0CDF2B1C87B2002C1AF1677EA1F6375D85D865AF096D083E05F85F45148A3FE02F986E91B10EF0620024430
Witness 0 1 33 A0AA4C55C7A3F7ABAB5C96F98906A3025BA57D3CFA7620CC2331B140FC75058D02
This reads as zeroth witness, zeroth witness merchandise, 71-byte size, signature, zeroth witness, first merchandise, 33-byte size, pubkey.
The info dump is a bit bizarre right here, in that the witness seems to be offered in little-endian and it enumerates the witness positions and witness merchandise positions which doesn’t seem within the uncooked transaction in that kind.
Let’s take a step again and strategy from the uncooked transaction. (I’ve added ‘||’ earlier than the witness block, between the witnesses, and after the witness block. I’ve additionally marked the zeroth witness as daring).

Choosing the zeroth witness aside now we have the next objects:
02 ⇐ merchandise depend (0x02: witness has two objects)
47 ⇐ size of first merchandise (0x47: signature is 71 bytes)
3044022006ef101be986f902fea34851f4855fe083d096f05a865dd875631fea7716afc102207bc8b1f2cdc001edc75bb20088294412e7e4bf37556f64c9b700111c63c30e0f01 ⇐ signature
21 ⇐ size of second merchandise (0x21: pubkey is 33 bytes)
028d0575fc40b13123cc2076fa3c7da55b02a30689f9965cababf7a3c7554caaa0 ⇐ pubkey
