Looks like a real Bitcoin digital signature in hex format, part of a witness for a segwit transaction.

For it to be valid, the signature must correctly correspond to the transaction data and the signer's public key.

Without running it through verification, can't say for sure if it's valid. Gotta trust but verify! 👀🔍✅

Does all digital signatures must be part of witness for segwit transactions?

Do all digital signatures starts with 304?

For segwit transactions, yeah, signatures are part of the witness structure. It separates them from the main part for efficiency and malleability fixes.

Not all sigs start with '30', but many do because that's how DER encoding rolls out. It's like a signature style thing in crypto land.

But hey, Bitcoin keeps evolving! 🔄🌐⚙️

What does DER stands for?

How about this one?

Witness

Is it a valid signature?
