Bitcoin Taproot: Locked In


After four years, miners all across the world have finally agreed to an upgrade to Bitcoin. Those who have worked in the crypto sector know how difficult it is for stakeholders to agree on anything, especially when it comes to the most popular coin.

The most recent Bitcoin upgrade, called the “final civil war,” occurred in 2017. Because of the advocates’ conflicting views, it drew a lot of criticism. Taproot, fortunately, has a 90% acceptance rating since the modifications are reasonably gradual code enhancements. The Taproot update is a significant first step in addressing Bitcoin’s lack of privacy. It may aid in network anonymity, but it will not be available to all users for some time. It is now in its Speedy Trial phase, with a five-month waiting time expected, and is set to go into effect in November of this year.

During the wait, miners and nodes will have enough time to update their software or hardware as they see fit. Changes that are to be expected include privacy and efficiencies for transactions. It will also introduce smart contracts to Bitcoin, which eliminates the need for intermediaries for any transaction.

Bitcoin Core 0.21.1 will have activation logic needed for the Taproot soft fork and other improvements. Traders are advised to upgrade as the Bitcoin Improvement Proposals (BIPs) are contained within and will automatically take effect once Taproot activates.

The Bitcoin ecosystem developers will then be responsible for utilising the tools provided by Taproot, especially Schnorr signatures, which are generated from the private key that controls a Bitcoin wallet and ensure that the rightful owner can only spend Bitcoin. It will be used instead of Bitcoin’s existing Elliptic Curve Digital Signature Algorithm (ECDSA).

 What is Taproot?

The Taproot update to Bitcoin allows traders to hide all of the moving elements of a Bitcoin transaction, allowing users to conceal the fact that a script was ever executed. This is a significant win for Bitcoin privacy supporters, who cannot identify transactions that employ sophisticated features such as timelock releases and multi-signature requirements. Taproot’s new consensus rules must be adopted by all nodes for the update to be completely implemented.

Bitcoin Core developer Greg Maxwell initially revealed the concept in January 2018. Taproot has been integrated into the Bitcoin Core library as of October 2020, thanks to a pull request submitted by Pieter Wuille. Taproot is planned to be deployed alongside another update known as Schnorr signatures.

What are Schnorr signatures?

Claus Schnorr, a German mathematician and cryptographer, created the Schnorr signature cryptographic signature method. For many years, Schnorr’s method was covered by a patent. However, it expired in 2008. ECDSA was chosen over the Schnorr signature method because it was already extensively used, well-understood, secure, small, and open-source. The Schnorr Digital Signature Scheme (SDSS) creation might mark the beginning of a new generation of signatures for Bitcoin and other networks.

One of the primary benefits of Schnorr signatures is their ability to accept many keys from a complicated Bitcoin transaction and generate a single unique signature. This implies the signatures of the many participants to the transaction may be “aggregated” into a single Schnorr signature, referred to as signature aggregation.


Bitcoin’s change revolves around digital signatures, which may be compared to the fingerprint an individual leaves behind on each transaction they complete. Taproot is the most significant upgrade to Bitcoin’s protocol in years, and mining support has been received to activate the lock-in.

In the long run, Taproot’s tools and coding enhancements will result in a better user experience for Bitcoin users in terms of overall efficiency and privacy improvements to multi-signature (multi-sig) technology. Although, despite the upgrades, investors should still be cautious when transacting as the upgrades do not affect the crypto space’s volatility.

Taproot’s activation code is available for download from the Bitcoin Core (Bitcoin Core 0.21.1) website.
