It’s kind of funny that something that didn’t officially exist before 2009 may well be one of the most important things ever for the future of society in the developed world, and quite possibly in other parts of the world as well.
What makes blockchain so important is that it brings something into distributed networking that isn’t technically a solid reality in the Internet as we know it today.
Blockchain technology provides the basis for a network of trust
The most important feature of the Internet is that it is decentralized, meaning there is no single part of it that can be switched off in order to destroy the whole thing. It also means there is no single authority that can dictate the terms. Instead, the Internet is loosely governed by consensus.
All this sounds quite Utopian until it is considered that in the absence of strict governance, absolute trust is difficult to achieve. To solve this situation, complex systems have been developed to try and establish the authorship and ownership of information that resides on the Internet. These include techniques such as digital signatures, file checksums, and security certificates.
One of the barriers to this prior to 2009 is that the Internet is divided in a power struggle between two major unofficial factions. On one side, there is an amalgamation of big business and government which favors strict control, heavy regulation, and the removal of power from individuals to act autonomously.
On the other side, you have just about everyone else, including many of the people who are most influential in advancing the Internet and building the technology that makes it a worthwhile thing to use.
The general tendency of this faction (and the tendency gets stronger the higher up you go in terms of how influential a person or group is) will be democratic libertarianism and even anarchy to some extent.
As an example, the first faction invests billions into developing tools and techniques for tracking people as they go about their business online. Developers from the second faction create tools that thwart those tracking techniques and share them freely to anyone who wants them.
With the creation of blockchains, a new possibility has been opened up. It’s a possibility where you can test the provenance of a chain of related data items without necessarily needing to know anything else.
Data owners can establish a chain of trust without needing to relinquish any control to any central authority.
You can use the power of blockchain to benefit you
Business entities can make use of blockchain technologies in many ways. An important feature is that this technology can help level the playing field, allowing smaller businesses to obtain data insights that previously would have been out of their reach.
You can also create end to end supply chain tracking, develop Smart Contracts, and even create your own decentralized applications.
Decentralization is the major benefit to both business entities and individual persons, because it means you can participate in the online marketplace without surrendering your autonomy.
This could be why China has been such a strong opponent of cryptocurrency. China is in the process of developing a social control system that would enable the central government to allow or deny privileges based on an individual’s family connections, behavior, spending habits, academic performance, and personal history.
Cryptocurrency allows an individual to participate in an economy that is not under the direct control of a government, and that is not acceptable if you want to put restrictions on what people can do with their money.
To put it simply, cryptocurrency empowers people to sidestep fiscal totalitarianism, and that is why no government anywhere is willing to consider cryptocurrency as legal tender, but people are using it anyway.
They are using it because it can be used as a negotiable instrument without any central authority to being able to interfere in the negotiation. It has value determined by the open market, and can be converted to ordinary fiat currency with relative simplicity.
Whether you are an individual or a company, you can make this power work for you, provided you understand the technology. There are many existing possibilities, and the list is only going to grow as the technology is further developed.
