Taproot
The Taproot upgrade is a significant update to the Bitcoin blockchain that was activated on November 14, 2021. It incorporates three key Bitcoin Improvement Proposals (BIPs): BIP 340, BIP 341, and BIP 342. These collectively enhance Bitcoin’s functionality in several ways:
- Schnorr Signatures (BIP 340): This introduces a new cryptographic signature method that is more efficient than the previous Elliptic Curve Digital Signature Algorithm (ECDSA). Schnorr signatures allow for the aggregation of multiple signatures into a single one, which simplifies and speeds up the verification process. This is especially beneficial for transactions involving multiple parties and can lead to reduced transaction fees and smaller transaction sizes.
- Taproot (BIP 341): This proposal enhances the privacy and efficiency of Bitcoin transactions by implementing Merklized Alternative Script Trees (MAST) and a new transaction type called Pay-to-Taproot (P2TR). MAST allows for the compression of complex transaction data, improving scalability and privacy since only the necessary parts of the script are revealed when a transaction is spent.
- Tapscript (BIP 342): This updates Bitcoin’s scripting language to accommodate the changes introduced by Schnorr and Taproot, allowing for greater flexibility and the potential future expansion of Bitcoin’s smart contract capabilities.
The Taproot upgrade is significant because it improves the privacy, efficiency, and scalability of Bitcoin transactions. It also lays the groundwork for more sophisticated smart contract applications directly on Bitcoin’s blockchain, which could enhance the network’s functionality and compete with other smart contract platforms like Ethereum. Additionally, the upgrade is designed to be backward-compatible as a soft fork, meaning it does not force all nodes on the network to update but rather allows them to opt-in oai_citation:1,A beginner’s guide to the Bitcoin Taproot upgrade oai_citation:2,What Is Taproot?

Ordinals:
Ordinals is a protocol on the Bitcoin network that allows the inscription of arbitrary data directly onto individual satoshis, the smallest denomination of Bitcoin. This development was introduced following the Taproot update in 2021, which allowed more data to be included in Bitcoin blocks, thus expanding the network’s capabilities.
The concept of ordinals is based on the idea of giving each Satoshi a unique “serial number” or “ordinal number” which reflects the order in which it was mined. This allows for each Satoshi to carry unique data, essentially transforming it into a non-fungible token (NFT) on the Bitcoin blockchain. Users can inscribe various types of data, such as text, images, or audio, making these satoshis collectible and tradable as digital art or other forms of digital assets.
This innovation has opened up new possibilities for Bitcoin, traditionally seen only as a cryptocurrency, by enabling it to host NFT-like assets directly on its blockchain. It has also attracted new users and investors interested in the NFT space to the Bitcoin ecosystem, despite also leading to increased transaction fees and network congestion due to the heightened activity.

The BRC-20 token standard is a new development on the Bitcoin blockchain, introduced to enable the creation and transfer of fungible tokens similar to the ERC-20 tokens on the Ethereum network. It utilizes the Bitcoin Ordinals protocol, which was made possible by the Taproot update in 2021. This update increased the amount of data that could be included in Bitcoin blocks, facilitating new functions like Ordinals and, subsequently, BRC-20 tokens.
BRC-20 tokens are simpler than many blockchain tokens because they do not require complex smart contracts. Instead, they use JSON data inscribed directly onto satoshis (the smallest unit of Bitcoin) to create and manage tokens. This makes the process of minting and transferring tokens more accessible to those without extensive technical expertise.
However, the BRC-20 standard has its drawbacks, primarily due to its reliance on the Bitcoin blockchain’s infrastructure, which is known for its low scalability and slow transaction speeds. This has led to increased transaction fees and network congestion, particularly as the number of tokens and their usage has grown. Additionally, the BRC-20 lacks support for smart contracts, limiting the range of functionalities that can be implemented compared to other token standards like ERC-20.
Despite these challenges, the introduction of BRC-20 tokens represents a significant step in diversifying the types of applications and utilities that can be developed on the Bitcoin network. The standard has seen a rapidly growing number of tokens being created, with varying degrees of success and acceptance within the community.
