What is Taproot?

Taproot (BIP 340) is an upgrade to Bitcoin which brought several new features (Schnorr Signatures, Taproot & Tapscript).

Schnorr Signature: Taproot utilizes the Schnorr signature algorithm, which, compared to traditional ECDSA signatures, offers higher efficiency and better properties. Schnorr signatures support aggregation, allowing multiple signatures to be merged into one, reducing the size of transactions.

Merkle Tree: Taproot merges all possible paths of a multi-party transaction into a single Merkle root using a Merkle tree. This makes it appear on the blockchain that all these paths converge to the same Taproot address.

Tapscript: Taproot introduces a new scripting language called Tapscript, enabling more flexible smart contract operations. This allows Taproot to support more complex conditions and rules, providing greater possibilities for various scenarios.

What is Taproot Assets?

Taproot Assets is a protocol based on the Bitcoin blockchain for issuing and transferring assets. The protocol allows users to create and manage multiple assets within a single Bitcoin Unspent Transaction Output (UTXO) and places witness data off-chain, thereby enhancing privacy and scalability.

Here are some key features of Taproot Assets:

  1. Native Support: The protocol is native and does not rely on second layers or sidechains but directly leverages the functionality of the Bitcoin blockchain.

  2. Efficiency: By utilizing Taproot transactions, Taproot Assets can bundle multiple assets within a single UTXO for submission and transfer, reducing on-chain resource consumption and associated costs.

  3. Privacy: Asset information and logic are concealed within Taproot scripts, making all transactions appear the same and increasing transaction privacy.

  4. Flexibility: Users can customize the properties and rules of assets according to their needs and preferences.

  5. Innovation: Provides more possibilities for the extension and innovation of Bitcoin, such as interoperability with the Lightning Network, support for multi-asset payment channels, and other innovative features.

What is EVM?

EVM(Ethereum Virtual Machine) is a key component of the Ethereum blockchain, serving as a virtual computer or software platform for developers.

It is a virtual machine that executes smart contracts on the blockchain and is the environment on which all Ethereum accounts and smart contracts depend.

EVM is a lightweight virtual machine that has similar functionality to traditional computers, including support for conditional judgments, loops, function calls, etc.

Its main purpose is to execute smart contracts, which can implement various functions, such as decentralized applications (DApps), digital asset transactions, etc.
