What You Should Know About Bitcoin’s Taproot Upgrade

Bitcoin (BTCUSD) recently completed the most significant network update in the last four years. The overhaul, dubbed Taproot, aims to streamline transaction processing and make it more efficient in terms of speed and cost. 1 The most recent update to the cryptocurrency’s network led in a “civil war” of sorts, with bitcoin cash (BCSHUSD) being created as a new cryptocurrency. The Taproot update, on the other hand, is uncontroversial.

What is the purpose of the Taproot Upgrade?

Simply said, the Taproot update combines many signatures and transactions into a single batch. On the Bitcoin network, digital signatures are required to verify transactions. They’re made with private keys and cross-validated with public keys.

Because each digital signature was validated against a public key before Taproot’s implementation, transaction verification on the Bitcoin network was slow. For sophisticated multi-sig transactions requiring several inputs and signatures, this strategy increased the amount of time necessary.


Signature aggregation is possible with the Taproot implementation.2 To put it another way, this means that many signatures can be grouped and validated. The benefit for multi-sig transactions—or transactions that require approval from multiple parties—is even greater because the upgrade condenses transactions with multiple inputs, such as those from multiple Bitcoin addresses, into a single one.

In addition, the Taproot upgrade unifies single-signature and multi-signature transactions into a single verification process. The change also has privacy consequences because it makes distinguishing between single-signature and multi-signature transactions more complex. As a result, identifying the participants in a transaction on Bitcoin’s public blockchain will become increasingly difficult.


A blockchain is a decentralized database that is shared among computer network nodes. A blockchain acts as a database, storing information in a digital format. Blockchains are best recognized for preserving a secure and decentralized record of transactions in cryptocurrency systems.


Taproot Enables Signature Aggregation in What Way?


To create keys and authenticate transactions, Bitcoin already use the Elliptic Curve Digital Signature Algorithm (ECDSA). Schnorr signatures, which are more secure and easy to deploy, are included in the Taproot upgrade.

Linearity is one of the features of Schnorr signatures. Simply put, this property allows you to sign a set of signatures with a set of public keys. As a result, instead of evaluating a single Bitcoin transaction at a time, many Bitcoin transactions can be confirmed fast in batches.
What Does the Taproot Feature Mean for the Bitcoin Network?


As previously stated, the Taproot upgrade streamlines transaction processing, making confirmation of transactions on the Bitcoin network easier and faster. Because the size of transactions grows, it also increases the number of transactions that can be handled and lowers the overall cost of transactions on the network.


One may argue that the Lightning Network, which is a Layer 2 technology, is designed to achieve the same goal. Once a channel is closed, however, transactions that occur on Layer 2 channels must be validated on the Bitcoin network. When batches of unprocessed transactions are sent to the Bitcoin network for confirmation, the network might get clogged. The Taproot improvement could make Bitcoin’s network more efficient at processing these transactions if it is implemented.


The Taproot update is also helpful for privacy since it disguises multi-signature transactions as single-signature transactions on Bitcoin’s public blockchain, making it impossible to identify participants in a transaction.

Finally, Taproot’s implementation is a triumph for smart contracts on the Bitcoin network. It could pave the way for additional creative financial applications to be developed on the Bitcoin network. According to others, the Taproot upgrade could also suggest that Bitcoin will play a role in Decentralized Finance (DeFi). Despite the fact that the cryptocurrency’s blockchain has always had smart contract functionality, it has never been used to its full potential due to transaction scaling issues. That issue is addressed by the Taproot implementation.


What Impact Does the Taproot Implementation Have on Bitcoin?


Bitcoin’s chances of becoming an effective transaction medium are increasing as it scales and becomes more efficient at processing transactions. Bitcoin’s value as a store of value has previously been linked to its utility. As a result, it’s possible that the value of bitcoin will rise as the number of useful transactions on its network grows.


When Bitcoin reaches its rumored limit of 21 million, miners’ revenue from bitcoin mining rewards will decline. Transaction fees will account for the majority of their revenue at that time. By decreasing transaction sizes and enhancing the speed with which they are processed on Bitcoin’s network, the new upgrade helps to bring that reality closer.
