Introduction
The 2008 global financial crisis led to the emergence of a mysterious white paper from an unknown entity, a person or group calling themselves Satoshi Nakamoto. This paper discussed a new peer-to-peer financial system using a digital cryptocurrency called Bitcoin. Many people saw this new system as a better way of doing things, and the technology invented to power this system was called blockchain.
What is Blockchain?
Blockchain is the underlying technology behind cryptocurrencies like Bitcoin and Ethereum, but its uses go far beyond that. In simple terms, blockchain is a continuously updated record of who holds what. These records are split into linked blocks and secured using cryptography. This cryptography ensures the authenticity of the records, creating what is known as automated trust or trust that’s inherently built into the system. The list of records, known as a distributed ledger, is decentralized and available for everyone to see and verify. Additionally, blockchain is tamper-evident and unhackable due to its distributed nature.
Blockchain Beyond Cryptocurrencies
Blockchain has a social perception strongly related to Bitcoin and other cryptocurrencies, and many people view it as something for intellectual, tech-savvy criminals or anti-establishment individuals. However, blockchain has applications far beyond cryptocurrencies and is poised to be revolutionary.
The Internet of Value
Our current internet is an internet of information, based on copying and distributing information like videos, emails, and data. However, blockchain enables a new stage of the internet based on real value, allowing for the secure transfer of assets like contracts, ownership titles, stocks, bonds, money, votes, and digital identities.
The FITS Model
The FITS model is a framework for identifying suitable blockchain applications. According to this model, blockchain is best applied in environments with a high possibility of fraud (F), the presence of intermediaries (I), high throughput requirements (T), and the need for stable data (S).
Current Blockchain Applications
Blockchain is already being used in various applications, including:
- Land registries in Honduras and Sweden
- Tracking diamonds to prevent the trade of blood diamonds
- Nasdaq’s blockchain system for recording trading in privately held companies
- Banks using blockchain for clearing and settling transactions
- Social media platforms like Steemit and DTube that use blockchain to pay users for creating content
Decentralized Autonomous Organizations (DAOs)
Blockchain technology has enabled the creation of Decentralized Autonomous Organizations (DAOs), which are distributed and automated company organizations. DAOs use computer code and smart contracts to run the rules and decisions of the organization, rather than a central management team.
Conclusion
Blockchain technology has the potential to revolutionize various industries and aspects of our lives. From finance and supply chain management to social media and organizational structures, blockchain’s impact is likely to grow in the coming years.
