Although Taproot took some time to gain momentum, its use cases have continued to grow since integrating Bitcoin-based Ordinal inscriptions and its November 2021 implementation with Bitcoin.

This article will delve deeper into the use cases for Taproot, focusing on Ordinal inscriptions and stablecoins built on Bitcoin, to better understand the innovative new features it brings to the table.

Bitcoin-Based Ordinal Inscriptions

Ordinal inscriptions present a groundbreaking development in Bitcoin, enabled by integrating the Taproot upgrade. In essence, Ordinal inscriptions involve attributing a unique ordinal number to each satoshi within the Bitcoin network. This numbering scheme, conceived by software engineer Casey Rodarmor, allows for precise tracking and verification of individual satoshis. It’s essential to grasp the concept of cryptographic signatures to understand the significance of ordinal inscriptions.

Cryptographic signatures form the bedrock of security within the Bitcoin network. When a user initiates a Bitcoin transaction, they must verify ownership of the coins through a digital signature. Traditionally, Bitcoin employed the Elliptic Curve Digital Signature Algorithm (ECDSA). However, the introduction of BIP 340, a component of the Taproot upgrade, unlocked Schnorr Signatures—a more secure alternative.


Schnorr Signatures bolster theoretical security in Bitcoin transactions and facilitate key and signature aggregation. That enables more efficient and private multi-signature setups. In a multisig scenario, where multiple parties must sign a transaction, Taproot allows for the trustless combination of public keys into a single key. This innovation enhances privacy and boosts efficiency, as Schnorr signatures are approximately 10% more efficient than their ECDSA counterparts.

How Taproot Enables Ordinal Inscriptions

The seamless integration of the Ordinals protocol with the Taproot upgrade has been pivotal for Bitcoin’s evolution. The Taproot upgrade, composed of BIPs 340, 341, and 342, introduced significant enhancements to Bitcoin’s functionality.

Stablecoins are a pivotal advancement within cryptocurrency, aiming to mitigate the notorious volatility prevalent in standard cryptocurrencies like Bitcoin and Ethereum. Unlike their more volatile counterparts, stablecoins are engineered to maintain a stable value by pegging it to an external asset, a fiat currency, a basket of currencies, or even a tangible commodity.

The primary objective of stablecoins is to serve as a reliable medium of exchange and store value within the cryptocurrency ecosystem. By tethering their value to established assets or commodities, stablecoins provide users with a degree of predictability crucial for widespread adoption. This stability fosters confidence in the digital currency, attracting a broader spectrum of users, including risk-averse investors and institutions.


Advantages Over Standard Cryptocurrencies

In contrast to standard cryptocurrencies, stablecoins offer price stability that aligns more closely with traditional financial instruments. It makes them particularly attractive for daily transactions and financial applications, as they sidestep the wild price swings that often deter potential users. By reducing the inherent volatility, stablecoins can catalyze greater adoption and integration into mainstream financial systems.

Taproot’s Influence on Developing Stablecoins on Bitcoin

Taproot has played a transformative role in the development of stablecoins. By incorporating Schnorr signatures and the Tapscript scripting language, Taproot enables the creation of intricate smart contracts and digital assets on Bitcoin while preserving user privacy.
