Taproot is an upgrade to the Bitcoin network that enhances privacy, scalability, and smart contract functionality. It allows multiple transactions to be bundled together, making them appear as a single transaction on the blockchain. This helps to obscure the details of individual transactions, improving user privacy. Additionally, Taproot introduces a new scripting language that enables more complex smart contracts. This means developers can create more sophisticated applications on the Bitcoin network, expanding its use cases beyond simple transactions. Overall, Taproot aims to make Bitcoin more efficient and versatile for users and developers alike.
