Securing Native Assets on Bitcoin: Leveraging Taproot's Upgrade

The recent Taproot upgrade on the Bitcoin (BTC) network has brought forth a new era of possibilities, particularly in terms of enhancing the security of native assets within the BTC ecosystem. This upgrade introduces several key features that significantly bolster the network's capabilities:

• Schnorr Signatures: With the implementation of Schnorr signatures, BTC now has a multi-signature method that can accommodate up to 1000 participants. This innovation not only enhances security but also provides greater flexibility in managing and securing native assets.

• MAST (Merkelised Abstract Syntax Trees): MAST allows for the combination of scripts from multiple Unspent Transaction Outputs (UTXOs) through a Merkle tree structure. This advancement simplifies and streamlines the scripting process, making it more efficient and versatile.

• Tapscript: Taproot's upgrade also includes improvements to the Bitcoin scripting language with Tapscript. This enhancement enables the verification of a series of scripts to determine whether a UTXO can be spent. It opens up opportunities for various operations, including withdrawals and penalties, within Layer 2 solutions.

In the initial stages of Tuna Chain's development, we will employ a multi-signature approach to protect native assets on the BTC network. Each multi-signature address will also serve as a validator for the Tuna Chain ecosystem. These validators will play a crucial role in independently calculating and verifying network state updates through the Data Availability (DA) layer. Their consensus will determine the release of assets on the BTC network, ensuring the highest level of security and reliability.

As Tuna Chain continues to evolve, our roadmap includes plans to introduce reputable external validators. These validators will further enhance the security and decentralization of the network. In the long term, we aim to expand the network's validation nodes, making it even more decentralized and robust. This strategic approach aligns with our commitment to safeguarding native assets on the BTC network and ensuring the utmost security for users and their digital assets.
