The Schnorr Digital Signature Scheme (SDSS), named after the German mathematician and cryptographer Claus Schnorr, is incredibly efficient and generates short signatures. The key innovation is that the same security level can be achieved using fewer bits of information in the digital signature. Moreover, it allows several signatures in a transaction to be combined into one.

2. Merklelized Abstract Syntax Trees (MAST)

Why does Bitcoin need Merklelized Abstract Syntax Trees? Because every Bitcoin transaction requires a script (instructions a computer can understand) rather than only a digital signature, there was lots of unnecessary data being included on the blockchain.

MAST helps reduce that unnecessary data, making it possible to either reduce transaction sizes or use more complex smart contracts.

In a way, it’s expected to allow developers to do more (functionality), for less (data required).

Some expect this may result in Bitcoin-based applications that are similar to existing Decentralised Finance (DeFi) projects, which are generally more closely associated with alternative blockchain systems.[13][14] This remains to be seen, however, Taproot’s ability to reduce the cost and increase the functionality of more intricate and complicated transactions may indeed offer room for more creativity outside of Bitcoin’s base layer.

To be clear, Taproot will not enable the same fully expressive and recursive smart contracts that exist in alternative blockchain systems (Ethereum, Solana etc.) and this will almost certainly never happen as recursive smart contracts are widely considered to be unacceptably risky for Bitcoin.

One major advantage of the Schnorr scheme is the ability to use

multiple keys within a complicated transaction on the bitcoin network and create one, completely unique

signature.

Taproot (BIP341)

Taproot is the component of the update from which it gets its name. It is based

on the 2017 SegWit update and makes use of the Merkelized Alternative Script Tree (MAST)

concept to scale the total data of transaction in the blockchain.

Public and private keys protect all transactions on the network. In order to move a

digital asset from your crypto wallet, senders are required to give a signature and prove that they

are the true owners before they are authorized to transfer funds.

A smart contract is a self-executing agreement built on a blockchain, and it allows two individuals to create a secure transaction without a third party like a lawyer.

Smart contracts have plenty of potential in the real world. They make it possible to borrow or lend money securely without a legal contract, for example, and they could potentially revolutionize the banking and finance industries.

Is Bitcoin a smart investment?

Although Taproot does strengthen Bitcoin, it’s important to consider how much of an advantage the cryptocurrency will have over its competitors.

When it comes to smart contracts, for instance, Ethereum(ETH2.55%) is by far the biggest player in the space.

By reducing the transaction size and making nearly all transactions appear like a simple, single-signature one, Taproot will enable larger, more complex operations to be deployed on the bitcoin network. In summary, Taproot was designed to improve bitcoin’s efficiency, privacy and security and I think it will do just that over time.

The run-up to Taproot’s activation, in part, spurred a bitcoin rally, launching bitcoin’s price to an all-time-high of $69,000 on November 10th 2021, demonstrating the excitement fueling the latest major upgrade.Although we are currently going through a minor correction, the Taproot upgrade will have a positive and lasting impact on the protocol for years to come.

Improvements in security

For people that enjoy their privacy, the Taproot upgrade will be of interest to them.

ECDSA), and without introducing any new assumptions. Throughout Taproot’s proposal process, it has been widely considered that this new signature scheme is just as secure, if not more secure, than the existing digital signature encryption applied to Bitcoin transactions.[6][7][8]

Given its superior qualities, it is likely that the reason Bitcoin didn’t use Schnorr signatures from the beginning is that it had only recently been released from patent in 2009, and very few people had any experience implementing the scheme.[9] The existing ECDSA signature scheme was a part of OpenSSL[10], a set of open-source encryption tools that were mostly developed by computer scientists and mathematicians, many of whom were on the mailing list where Bitcoin was originally shared.

This may well push Bitcoin out of the category as just a “store of value”.

Summary

The upgraded functionality of the Bitcoin network is paramount to its continued success as a digital currency. With the industry in overdrive and Bitcoin no longer being the only fish in the sea, updates are necessary to ensure the continued safety and efficiency of its infrastructure.

Nonetheless, Taproot has successfully been activated at block height 709,632, or sometime on 13-14 November 2021 depending on your timezone. For those interested in participating or supporting this change, you can upgrade to Bitcoin Core version 0.21.1 (or later release) to enforce these rules. However, users who choose not to upgrade will continue to participate in the network and interact with others who opt for Taproot without any disturbance to their Bitcoin node.
