SegWit, a process by which the block size limit on a blockchain is increased by removing signature data from Bitcoin transaction, has successfully locked-in the Bitcoin network. Still, it seems like Bitcoin's Core developer team isn't done scaling the cryptocurrency's protocol.
Thus, while a lot of users are looking for more aggressive scaling via the controversial Segwit2x proposal, Bitcoin Core team is working on other technology called "Schnorr signatures". It offers another signature scheme option alongside Elliptic Curve Digital Signature Algorithm (ECDSA). One benefit is that it supports "signature aggregation" on the Bitcoin blockchain. Hence, the change aims to consolidate activity that already takes place on the network with each transaction. Under the ECDSA scheme, each piece of a Bitcoin transaction is signed individually, while with Schnorr signatures, all of this data can be signed once.
As a blockstream engineer, Jonas Nick, claims to coindesk.com, this method of mashing signature data together should be considered "low-hanging fruit for helping bitcoin scale". First, by decreasing the number of signatures, it increases the amount of transaction data that can fit into each block. Second, by merging signatures, the technology could enhance privacy by making it harder to determine where transactions are coming from. Third, it's believed the change could curb "spam attacks", where one entity sends a bunch of small bitcoin transactions that take up extra space in the blockchain, potentially making nodes more difficult to run.
