Bitcoin Protocol Upgrades Enhance Scalability and Security

Segregated Witness (SegWit) and Taproot represent significant advancements in Bitcoin's protocol, addressing key limitations in transaction structure and scripting. According to NS3.AI, SegWit resolved transaction malleability issues, paving the way for scalable second-layer solutions. Meanwhile, Taproot enhanced script efficiency and privacy through the use of Schnorr signatures and Merkle trees. These upgrades collectively establish a crucial foundation for Bitcoin's scalability, security, and future enhancements.
