What is bitcoin native SegWit & taproot?
Could you elaborate on the concepts of Bitcoin's native SegWit and Taproot? As a financial and cryptocurrency professional, I'm interested in understanding how these technologies enhance Bitcoin's efficiency and scalability. SegWit, or Segregated Witness, is said to improve transaction malleability and allow for more transactions to be processed within a block. Taproot, on the other hand, is a proposed upgrade that aims to enhance privacy and flexibility through more efficient smart contract capabilities. Could you break down how these technologies work and the potential impact they bring to the Bitcoin ecosystem?
