Introduction

Bitcoin, a decentralized digital currency, has garnered significant attention since its inception in 2009. It operates on a peer-to-peer network and utilizes blockchain technology to record transactions. This analysis synthesizes research findings on Bitcoin's security, sustainability, decentralization, and its role in the financial ecosystem.

Key Insights

Security and Privacy Concerns:
- Bitcoin's security relies on the proof-of-work (PoW) consensus protocol, which incentivizes miners to maintain the blockchain honestly. However, this system has vulnerabilities that adversaries can exploit .
- Privacy issues are significant, with threats to user anonymity and various privacy-preserving solutions being explored .
Sustainability and Environmental Impact:
- Bitcoin mining is energy-intensive, with estimates of energy consumption ranging from 100 to 500 MW. This high energy demand raises concerns about the environmental impact of Bitcoin .
- The energy consumption of Bitcoin could potentially contribute significantly to global CO2 emissions, potentially pushing global warming above 2°C within a few decades if adoption rates continue.
Decentralization:
- Despite its promise of decentralization, a limited set of entities controls significant aspects of Bitcoin's services, decision-making, and mining processes, which can influence the network's direction.
Economic and Financial Role:
- Bitcoin is often used more as an investment rather than a currency, with its value and volatility being key characteristics. It is largely uncorrelated with traditional asset classes like stocks and bonds.
- Bitcoin has potential as a complement to emerging market currencies, offering ways to minimize risks and enhance financial systems in these markets.
Broader Applications and Future Trends:
- Blockchain technology, the foundation of Bitcoin, has potential applications beyond cryptocurrency, including medical data sharing, energy distribution, and state-driven cryptocurrencies .
- The Bitcoin protocol and its underlying technologies have influenced various fields, suggesting a broader impact beyond just digital currency.

Conclusion

Bitcoin's rise has highlighted significant issues related to security, privacy, and sustainability. While it offers potential benefits as an investment and a complement to emerging market currencies, its environmental impact and centralization concerns pose challenges. The underlying blockchain technology holds promise for broader applications, indicating that Bitcoin's influence extends beyond its role as a digital currency.

A Survey on Security and Privacy Issues of Bitcoin

Bitcoin's security and privacy are vulnerable, and future research should focus on addressing these challenges and providing stringent security and privacy solutions for the cryptocurrency.

Current Trends in Sustainability of Bitcoins and Related Blockchain Technology

Bitcoin's sustainability is limited by energy consumption and social issues, but blockchain technology may offer new opportunities for social change and a sustainable monetary system.

Sustainability of bitcoin and blockchains

Bitcoin mining consumes between 100-500 MW of energy, but energy consumption is not a primary concern for other blockchain applications.

Is Bitcoin a Decentralized Currency?

Bitcoin is not fully decentralized, as a limited set of entities controls its services, decision-making, mining, and incident resolution processes, bypassing the will of the many users that populate the network.

Bitcoin as a Complement to Emerging Market Currencies

Bitcoin has characteristics that make it a well-suited complement to emerging market currencies, and there are ways to minimize its risks.

Bitcoin and Beyond: A Technical Survey on Decentralized Digital Currencies

Bitcoin revolutionized digital currencies and influenced many fields, with key ideas from its protocol being applicable in various fields beyond Bitcoin itself.

Bitcoin: An Innovative Alternative Digital Currency

Bitcoin offers a decentralized, partially anonymous digital currency with low transaction costs and potential for anonymous transactions, but legal issues remain.

Bitcoin Concepts, Threats, and Machine-Learning Security Solutions

Bitcoin security relies on the distributed protocols-based stimulant-compatible proof-of-work, with machine-learning security solutions playing a crucial role in addressing emerging threats and advancing future research trends.

Bitcoin emissions alone could push global warming above 2°C

Bitcoin usage, if it follows the rate of adoption of other widely adopted technologies, could produce enough CO2 emissions to push global warming above 2°C within less than three decades.

Bitcoin: Currency or Investment?

Bitcoin is mainly used as an investment, not as an alternative currency, and its current size does not pose an immediate risk to monetary, financial, or economic stability.
