Bitcoin’s horizon just got significantly brighter as Lightning Labs announced that the latest version of the Bitcoin Taproot Assets protocol is currently under trial on the testnet, enabling multi-asset support through the Lightning Network.

The new protocol, a year in the making and initially launched under the Taro name, offers an exciting addition to Bitcoin’s capabilities – quick, cheap, and scalable asset issuance. This could foster wider Bitcoin usage, contributing to the growth of the digital asset ecosystem.

The Taproot Assets protocol aims to provide a revolutionary platform for issuing assets on the Bitcoin blockchain, to be transferred over the Lightning Network for instantaneous, high volume, and low-fee transactions. Taproot Assets takes advantage of the improvements brought about by the November 2021 Taproot soft fork to the Bitcoin protocol.

The system allows developers to embed asset metadata directly within the block space via each satoshi – an approach similar to the Ordinals protocol used for Bitcoin non-fungibles and BRC-20 tokens. A distinguishing feature, however, is that Taproot Assets integrates with the layer 2 Lightning Network, enhancing privacy and scalability. Asset minting occurs on the mainchain, with the added option for owners to move assets off-chain.

“Assets issued on Taproot Assets can be deposited into Lightning Network channels, where nodes can offer atomic conversions from Bitcoin to Taproot Assets,” explained a representative from Lightning Labs. This process could provide users with additional liquidity and flexibility when interacting with their digital assets.

The announcement came with an invitation for developers to download the Taproot Assets v0.2 daemon, encouraging thorough testing of its features to ensure reliability and efficiency. A firm date for the mainnet release was not provided, with the company only stating that it would be “coming soon.”

This development arrives amid a divided Bitcoin community. The Ordinals protocol, for instance, has sparked controversy. While advocates like MicroStrategy Chair Michael Saylor see it as a catalyst for adoption and a new era of application development on the chain, critics raise concerns over escalating fees, network congestion, and a lack of practical use-cases for BRC-20 tokens.

The advent of Taproot Assets, however, could be a turning point. Leveraging layer 2 technology, it addresses issues of high fees and network congestion. This potential improvement could appease critics who wish for Bitcoin to maintain its primary function as a monetary network while simultaneously driving further innovation and adoption.


In conclusion, the evolution of the Lightning Network via the Taproot protocol is a landmark event in Bitcoin’s journey. By enabling a new class of scalable, low-fee assets, it promises to foster further development and innovation in the Bitcoin ecosystem, potentially ushering in a new era of financial technology.
