As the Bitcoin halving event approaches, the concept of Bitcoin becoming a global settlement asset has attracted more and more institutions, and they have begun to lay out in this field. Whether it's RWAs (Real World Assets) or Ordinals (Inscribed Assets), they have to some extent promoted the goal of Bitcoin becoming a global settlement asset. In this process, Taproot Assets, as a Bitcoin meta-protocol directly integrated by the Lightning Network, will play an important role.

On October 21, Lightning Labs, the developer of the Lightning Network, announced the release of Taproot Assets v0.3 on the mainnet alpha version. This version will pave the way for issuing stablecoins and other assets on Bitcoin. Elizabeth Stark, CEO and co-founder of Lightning Labs, stated that Taproot Assets v0.3 heralds the arrival of a new era for Bitcoin, further solidifying its importance in the global financial system.

What is Taproot Assets

In the past week, Bitcoin has surged by more than 15%, breaking through the high point of 35,000 at one point. Bitcoin spot ETF has become the focus of the market, and the new narrative around Bitcoin has become the mainstream trend in the current crypto industry. In addition to the most anticipated Bitcoin spot ETF, a new way of issuing Bitcoin assets has also attracted investors' attention, and that is Taproot Assets.

Taproot Assets Protocol

Taproot Assets is a new protocol based on Taproot, aiming to achieve asset issuance on the Bitcoin chain. This protocol allows assets to be deposited into Lightning Network payment channels and transferred through the existing Lightning Network. Taproot Assets provides a complete set of tools for developers who are keen on issuing, managing, and exploring mainnet assets. The protocol introduces corresponding new features and improves scalability, security, and developer experience.

Taproot Assets was initially developed by Lightning Labs, a Bitcoin Lightning Network infrastructure developer. Founded in 2016, Lightning Labs is dedicated to improving the scalability of Bitcoin for faster and cheaper transactions. On October 21, Lightning Labs announced the launch of Taproot Assets v0.3, the latest version of the Taproot Assets protocol. A major highlight of this version is forward compatibility, ensuring that Taproot assets are not affected by any future protocol changes, providing stability and confidence for asset issuers and users.

Elizabeth Stark, CEO and co-founder of Lightning Labs, stated in an interview with The Block that Taproot Assets helps lead the "Bitcoin renaissance," making the Lightning Network a multi-asset network, further solidifying Bitcoin's position in the "Internet of Money" field.

Core Components of the Taproot Assets Protocol

Schnorr Signature Algorithm: Taproot Assets adopts the Schnorr signature algorithm, which is an efficient and more privacy-preserving Bitcoin transaction signature algorithm. Allowing multiple inputs to share the same signature, Schnorr signatures reduce the size of transactions, enhance privacy, and provide users with a more secure and efficient transaction experience.

Merkleized Abstract Syntax Tree (MAST): MAST is a data structure used to organize and verify complex scripts. Taproot Assets utilizes MAST to merge multiple conditions and branches into a single Merkle tree, reducing transaction complexity and size, and providing more flexible asset management and transaction rules.

Scriptless Scripts: Taproot Assets introduces Scriptless Scripts, a new contract feature introduced in Taproot. It allows for more complex conditions and protocols in Bitcoin transactions without publicly revealing scripts on the blockchain, enhancing transaction privacy, reducing transaction size, and providing users with a more secure and private transaction environment.

Core Features of Taproot Assets

Asset Issuance and Redemption: Taproot Assets allows asset issuers to issue assets in batches on the Bitcoin mainnet and destroy assets at any time, enabling flexible management of asset supply while ensuring the public can access the latest asset information.

Asynchronous Receipt Function: Taproot Assets supports asynchronous receipt, allowing assets to be sent and received even when the transaction parties are not online simultaneously. Associated with Uniform Resource Identifiers (URIs), the recipient's wallet can automatically synchronize and process newly received assets in the background.

Multi-Universe Mode: Taproot Assets adopts a multi-universe mode, where participants involved in asset transfers can verify and store information related to the assets. This information is stored in the issuer's local data storage or an information repository called "Universes," ensuring the validity of assets can be verified through other Universes even if the issuer's server fails.

Stablecoin Issuance: Taproot Assets are suitable for issuing stablecoins, tokens pegged one-to-one to fiat currencies. Combined with the Lightning Network, Taproot Assets provide stablecoin support and payment channel functionality for users, enabling Bitcoin-based stablecoins to be used for daily high-frequency payments, offering convenience and synergistic effects.

Atomic Swaps: The Taproot Assets protocol also allows for atomic swaps between assets and Bitcoin, handling unique and non-unique assets and collections. This means users can directly exchange different assets without involving third parties, achieving efficient asset liquidity and transfer.

Lightning Network Support: Assets under the Taproot Assets protocol can be stored in Lightning Network payment channels and transferred through the existing Lightning Network. As a second-layer solution for Bitcoin, the Lightning Network features high speed, scalability, and low fees, making asset transfers under Taproot Assets faster and more cost-effective.

Taproot Assets Leading a New Direction for Bitcoin Asset Issuance

In the cryptocurrency field, asset issuance and trading have always been the focus of attention. With the introduction of Taproot Assets, Bitcoin will usher in a new era, opening the door to a variety of asset transactions. The core concept of Taproot Assets is to integrate the transfer of assets with the security and stability of the Bitcoin chain. Through specific protocols and the Lightning Network, Taproot Assets not only support on-chain asset transfers but also enable off-chain asset transfers. This dual mechanism provides users with a double guarantee of flexibility and security. Additionally, through the design of the so-called "Pocket Universe," Taproot assets achieve the aggregation and verification of assets on the chain, further enhancing the security and privacy of asset transfers.

Compared to traditional asset issuance and trading methods, Taproot Assets brings many important innovations.

First, Taproot Assets enable multi-asset transactions on Bitcoin, providing users with a wider range of trading options. Both fungible and non-fungible assets can be expressed on the Bitcoin network through Taproot Assets. This openness and compatibility provide users with a more flexible, secure, and convenient trading experience.

Second, Taproot Assets introduce the speed, scalability, and low fees of the Lightning Network.

This allows Taproot assets to achieve large-scale transactions and reduce the burden of transaction fees. This is an important breakthrough for asset holders and trading participants, creating more business opportunities and trading possibilities for them.

Additionally, the design of Taproot Assets enables efficient, secure, and privacy-protecting asset transfers. Asset holders can conduct transactions with Taproot Assets in the same way as regular Bitcoin transactions. This means that the security and verification methods during asset transfers are consistent with the core technology of Bitcoin, without introducing additional risks. Furthermore, through the design of Taproot, the process of asset transfers is further optimized and protected, ensuring the privacy and security of asset holders.

Overall, the introduction of Taproot Assets not only brings more innovation and development opportunities to Bitcoin and the entire cryptocurrency field but also opens up new prospects for asset issuance and trading.
