Bitcoin is set to undergo a major network upgrade, Taproot, on Nov. 14 equally per data from Taproot.watch. This is the first significant upgrade since the Segregated Witness (SegWit), which somewhen culminated in the development and launch of the Lightning Network in 2022. The original Taproot proposal was made by Bitcoin cadre contributor and former Blockstream primary grooming officeholder Gregory Maxwell on Jan 23, 2022.

While the previous SegWit upgrade was aimed to resolve transaction malleability and improve the scalability of the Bitcoin network, the Taproot upgrade is targeted to meliorate transaction efficiency, the privacy of the network, and its ability to support smart contract initiatives. The upgrade was set into motion only after attaining a ninety% consensus amid the Bitcoin mining nodes on June 12, every bit announced by Bitcoin developer Hampus Sjöberg on Twitter. Sjöberg also made the Taproot.lookout man website to track the updates for the Taproot upgrade.

Ben Caselin, head of research and strategy at AAX, a cryptocurrency exchange, told Cointelegraph, "The Taproot Upgrade coming to Bitcoin is amid the most impactful changes to exist implemented on the network. The upgrade brings smart contract functionality to the protocol, and it optimizes for cost efficiency and privacy."

He too noted that the smart contract functionality coming to Bitcoin is significant even though there are so many high-performing protocols that are functioning already, stating "nosotros have to remember that Bitcoin is the but truly non-sovereign network that offers the highest degree of network security on the planet."

MAST and Schnorr Signatures

The soft fork volition introduce the Merkelized Abstract Syntax Tree (MAST). This tree will introduce a condition that will allow the sender and receiver of the transaction to sign off on a transaction together for settlement. Merkle trees are an established compact complex data structure that was invented by Ralph Merkle, one of the inventors of public-key cryptography.

Currently, Bitcoin uses the pay to script hash (P2SH) that ensures that merely a hash of the script is going on-chain. Thus, when tokens are existence spent, the underlying technology makes it necessary to show all the possible weather which could've been fulfilled, including those that weren't met in the transaction. The downside to this is that information technology is very information-heavy, which is unnecessary, and it's not ideal for privacy as anyone on the blockchain can investigate which ways the funds could've been spent, the kind of wallet beingness used, and possibly more of such details.

MAST ensures that the various conditions in which the funds can be spent are hashed individually and included in a Merkle Tree that will produce a Merkle root, which is a single hash. This ensures that only conditions which are met would demand to be revealed, thus making the network more than data-efficient than the previously used P2SH contracts.

Additionally, the Taproot upgrade will bring in the Schnorr Signature. This algorithm will allow users to aggregate multisigs into ane for a single transaction, making it difficult to differentiate betwixt regular transactions and multisig transactions. Essentially, these signatures hibernate if in that location is a MAST structure that existed from the token or transaction at any fourth dimension at all.

Igneus Terrenus, caput of communications at Bybit, a cryptocurrency derivatives exchange, spoke with Cointelegraph on the specifics of this upgrade:

"Using the trinity of Schnorr signatures, MAST and Tapscript, Taproot allows for less unnecessary data collection in Bitcoin network's transaction outputs without sacrificing security. Past virtue of less corporeality of data collected and transferred, the benefits for the end-users will be seen in better privacy, more efficiency, and lower transaction fees."

Terrenus also mentioned that the Taproot upgrade would accept a compounding event on the Lightning Network launched dorsum in 2022. Subsequently this soft fork, simple, complex multisig and Lightning Network transactions volition be treated equally on the network. This would unlock the true potential of the Lightning Network through increased efficiency and reduced discrimination on fungibility.

Marie Tatibouet, the main marketing officer at Gate.io, spoke with Cointelegraph about the larger impact that the Lightning Network has had already, specially in El Salvador's adoption of Bitcoin as legal tender. She said, "Strike — 1 of the well-nigh popular Lightning Network wallets — is responsible for powering El salvador'south crypto ecosystem. In a 3-month period betwixt May and July 2022, the number of lightning network nodes jumped from x,000 to 23,000. As things stand, information technology is projected that the Lightning Network could reach 700 million users by 2030."

Even though the upgrade will let the deployment of smart contracts and is the next logical upgrade for the Bitcoin network, information technology would be unrealistic to compete with the virtually utilized smart contract blockchain network, Ethereum, anytime soon. On this, Tatibouet said, "While it will accept some fourth dimension for proper contracts to function properly, the utility and user base information technology will bring in will exist certainly impressive. Yet, don't expect Bitcoin'due south smart contract ecosystem to eclipse Ethereum's any time soon."

Anto Bukov, the co-founder of 1inch Network, a decentralized cryptocurrency exchange, holds a more than absolute view regarding smart contracts. He told Cointelegraph, "Information technology was non designed for this purpose. Bitcoin is based on the UTXO model, which is non suitable for smart contracts. Cardano recently demonstrated this."

Short-term cost impact is limited

The days leading up to the upgrade take been interesting for Bitcoin equally an investment nugget besides. The token briefly hit an all-time high of $69,000 on November. 12 before crashing almost $7,000 to under the $63,000 price marking. The token currently trades only below the $64,000 as per data from CoinMarketCap. The asset currently has a market place capitalization of over $i.two trillion, holding over the coveted $1 trillion mark for nearly a week now.

Yet, the impact of this upgrade may already exist priced into the asset'due south current toll. Bukov further spoke about the impact on the end-user. He said, "We note interesting technical improvements in Taproot, but information technology hardly will bring whatever user impact except for marketing."

Caselin seemed to be more hopeful of the long-term price impact of this asset. He mentioned, "The immediate soft fork is priced in already. Anyone who understands and follows Bitcoin has been aware of Taproot and will take adjusted exposure accordingly. Nevertheless, since Bitcoin is yet under its fair value and a further surge this calendar month is widely expected, Taproot might provide the impetus. Nonetheless, in terms of its potential, Taproot has non been priced in at all."

Since the Taproot upgrade would reduce the transaction outputs on the network, it opens the possibility for the deployment of sophisticated smart contracts. One differentiator from other blockchain networks that already have advanced smart contract utilities like Ethereum, Solana, etc., is that Bitcoin's monetary functions and superior network security could concenter liquidity that stays in the network for long periods. This is an aspect that various decentralized finance (DeFi) protocols congenital on platforms like Ethereum currently struggle with, and are stepping into the DeFi 2.0 to address.

Caselin spoke more almost the marketwide impact, saying, "Bitcoin might take some market share away from smart contract platforms; however, it is more likely that mainstream participants in DeFi will stick to Ethereum, Solana, and similar protocols. Bitcoin is better suited for the more serious endeavors — and serious capital."

Irrespective of the brusque-term price affect that the Taproot upgrade might or might non take on Bitcoin, it is evident that the Taproot upgrade, coming in as the first upgrade for the network in iv years, is a major step for the network every bit it improves its fundamentals even further. Over the long term, this upgrade would drive value and could be seen as another step towards "hyperbitcoinization."
