Why Crypto Currencies are a bad bet for the next decade


Abstract:

The advent of quantum computing poses a significant threat to the value and stability of cryptocurrencies, particularly those not pegged to real-world assets. The security risks associated with quantum computing could lead to widespread devaluation as trust in these currencies erodes. Furthermore, the energy costs associated with classical computing in cryptocurrency mining highlight the unsustainable nature of current practices.

Introduction

Cryptocurrencies have become a significant aspect of the global financial landscape. They promise decentralization, anonymity, and freedom from traditional financial systems. A cornerstone of their value is scarcity, akin to precious metals like gold. However, the advent of quantum computing poses a substantial threat to the security frameworks underpinning cryptocurrencies. This paper explores why scarcity is crucial for cryptocurrency value, how quantum computing could lead to the devaluation of non-pegged cryptocurrencies, and the monetary theories that support this hypothesis.

The Importance of Scarcity in Cryptocurrencies

Scarcity is a fundamental concept in economics, particularly in the realm of currencies. For a currency to retain its value, it must not be easily reproducible. This principle is embedded in the design of cryptocurrencies such as Bitcoin, which has a fixed supply of 21 million coins. The limited supply creates a sense of scarcity, fostering demand and driving value.

Digital Scarcity

In the digital realm, creating scarcity involves complex algorithms and consensus mechanisms. Cryptocurrencies use cryptographic techniques to ensure that new units cannot be forged and transactions cannot be reversed once confirmed. This digital scarcity is paramount to maintaining the trust and value of the currency.

Quantum Computing: A New Paradigm

Quantum computing represents a revolutionary shift from classical computing. Utilizing the principles of quantum mechanics, quantum computers can perform complex calculations at speeds unattainable by classical computers. This leap in computational power, while promising immense benefits in various fields, also introduces significant risks to current cryptographic systems.

Quantum Threats to Cryptographic Security

Most cryptocurrencies rely on cryptographic algorithms such as RSA and ECC (Elliptic Curve Cryptography) for securing transactions and wallets. Quantum computers have the potential to break these algorithms due to their ability to solve complex mathematical problems, like factorizing large prime numbers, exponentially faster than classical computers. Shor's algorithm, for example, could break RSA encryption by factorizing large numbers efficiently, compromising the security of the blockchain.

Implications for Non-Pegged Cryptocurrencies

Non-pegged cryptocurrencies, such as Bitcoin and Ethereum, derive their value largely from market perception and scarcity. Unlike stablecoins pegged to real-world assets or fiat currencies, their value is highly volatile and speculative. The introduction of quantum computing into this ecosystem could have profound implications.

Devaluation through Security Breaches

If quantum computers can break the cryptographic codes that secure blockchain transactions, it would lead to massive security breaches. The immediate consequence would be a loss of trust in the security of these currencies, leading to a sharp decline in their value. Holders of such currencies would likely rush to sell, causing a market crash and devaluation.

Impact on Mining and Consensus Mechanisms

Quantum computing could also disrupt the mining process. Proof-of-Work (PoW) algorithms, which are computationally intensive and energy-consuming, underpin many cryptocurrencies. Quantum computers could solve PoW puzzles much faster, rendering the existing mining hardware obsolete and potentially centralizing mining power in the hands of those with quantum computing access. This centralization contradicts the decentralized ethos of cryptocurrencies and could further erode trust and value.

Monetary Theory and Cryptocurrency Valuation

Understanding the monetary theory behind cryptocurrency valuation is crucial to grasp the potential impact of quantum computing. Traditional monetary theory focuses on the functions of money: a medium of exchange, a unit of account, and a store of value. Cryptocurrencies fulfill these functions to varying degrees, with scarcity playing a vital role in their value as a store of value.

The Role of Trust

Trust is a fundamental component of any currency's value. For cryptocurrencies, trust is built on the security of the blockchain and the integrity of the network. Quantum computing's ability to compromise blockchain security directly undermines this trust, leading to potential devaluation.

Hyperinflation Analogies

The potential scenario of widespread quantum attacks on cryptocurrencies can be analogized to hyperinflation in fiat currencies. When a currency's value plummets due to overproduction or loss of confidence, hyperinflation occurs, eroding purchasing power and destabilizing the economy. Similarly, quantum-induced devaluation would erode the purchasing power of cryptocurrencies, leading to a loss of confidence and potentially rendering them worthless.

Energy Costs and the Downfall of Cryptocurrencies

Another critical aspect to consider is the energy cost associated with classical computing used in cryptocurrency mining. Bitcoin mining, for instance, consumes more energy than some entire countries. As quantum computing becomes more accessible, it could exacerbate these energy concerns in two ways.

Increased Energy Efficiency

Quantum computers, while currently energy-intensive, have the potential to become more efficient than classical supercomputers. This efficiency could make traditional mining operations obsolete, shifting the competitive advantage to those with quantum capabilities. However, the transition period could see increased energy consumption as miners scramble to maintain competitiveness.

Centralization of Mining Power

The high cost and technical expertise required for quantum computing could lead to the centralization of mining operations. This centralization is antithetical to the decentralized nature of cryptocurrencies and could undermine their value proposition. Centralized control over mining could lead to manipulation and increased susceptibility to attacks, further destabilizing the cryptocurrency market.

Conclusion

The advent of quantum computing poses a significant threat to the value and stability of cryptocurrencies, particularly those not pegged to real-world assets. The security risks associated with quantum computing could lead to widespread devaluation as trust in these currencies erodes. Furthermore, the energy costs associated with classical computing in cryptocurrency mining highlight the unsustainable nature of current practices.

Monetary theory underscores the importance of scarcity and trust in maintaining the value of any currency. Quantum computing's potential to break cryptographic codes threatens these pillars, suggesting a future where cryptocurrencies could face significant devaluation unless they adapt to the new technological landscape. As such, the development of quantum-resistant algorithms and new consensus mechanisms will be crucial in preserving the value and integrity of cryptocurrencies in the quantum era.

A lot of currencies are moving to proof of stake which moves away from mining. I know we're working on the next evolution of crypto algorithms which would be protected from advanced quantum computational calculations. I think with time, many crypto Currencies will evolve and use the next evolution algorithms. If not, we're gonna see a lot of empty wallets :(.
