Alyssa Hertig writes about Schnorr perspectives in cryptographic
"… At a technical level, adding support for Schnorr, a digital signature scheme, would give bitcoin users a new way to generate the cryptographic keys they need to used to store and send bitcoin. By doing so, it also paves the way for a number of exciting benefits, including tackling privacy and scalability, arguably two of bitcoin's most worrisome problems…"

A way forward
"…For one, the BIP draft helps to avoid future confusion by proposing a standard that ensures that all developers and merchants eventually implement the Schnorr signature code in the same way…"
"…Right now, it's obvious when users send so-called "multi-sig transactions," which are a more advanced type of transaction where more than one person is required to sign off on a transaction, because of bitcoin's public ledger. But Schnorr pave the way for a technique that will make these transactions look the same as every other transaction. Nick noted Schnorr will also lead these advanced transactions will be cheaper as well, an important improvement since transactions can grow very expensive in times of congestion…"

Less detractors?
"…Schnorr is a particularly big upgrade. Although changes are being made to bitcoin's most-used client every day, with code contributions coming from a diverse group of contributors stationed around the world, Schnorr is a rarer type of change, since it affects the most important rules in bitcoin.
SegWit was the last code change "consensus" change made to bitcoin, sparking a debate so big, those who disagreed with the change split off and created their own cryptocurrency with SegWit removed.
The most enthusiastic SegWit supporters even made hats to express their support for the code change. Blockchain consultant Francis Pouliot joked that similar advocacy hats should be made in advance of Schnorr, in case a similar vicious debate breaks out…"
