Today when a CoinJoin transaction has 100 inputs, then it must hold 100 signatures as well. With Schnorr, we can do it with only one signature. This will make CoinJoin transactions about 30–40% cheaper than normal transactions.

> What did we achieve here? Making a CoinJoin mixing transaction with a high anonymity set becomes about 30% cheaper than making a transparent, traditional Bitcoin transaction.

Thanks for the feedback! And thank you for working on fungibility!

I agree that it may seem unrealistic to get Bulletproofs on bitcoin as long as there are issues with a potential "inflation attack"

However we should be able go get Schnorr Signatures, that's just a soft fork isn't it..?

It's not totally clear to me from your answer above..Can you please confirm that we can achieve coin-join transactions that are cheaper than normal transactions with the use of Schnorr Signatures only?

So we actually don't need Bulletproofs for this to happen?
