Hello!
Could someone explain how and come out of scriptSig script? Of course, scriptSig in not equal concatenate(,). How is this information incorporated into scriptSig?
Thank you!
It's a script.
PUSHDATA opcode
Signature data
PUSHDATA opcode
Public key data
In this input of a transaction
scriptSig: 304502206e21798a42fae0e854281abd38bacd1aeed3ee3738d9e1446618c4571d10

where is the public key?
That is just the signature. The output that it spends is from doesn't require a pubkey because the output script includes the pubkey:
PUSHDATA(65)
04283338ffd784c1 ... 8af332fe4d8cde20
CHECKSIG
Here is a typical raw scriptsig (
