The technology first appeared in 2009 as the basis of the Bitcoin digital currency system, but it has potential for doing much, much more—including aiding in the development of platform cooperatives. Traditionally, institutions use centralized databases. For example, when you transfer money using a bank account your bank updates its ledger to credit and debit accounts accordingly. In this example, there is one central database and the bank is a trusted intermediary who manages it. With a blockchain, this record is shared among all participants in the network. To send bitcoin, for example, an owner publicly broadcasts a transaction to all participants in the network. Participants collectively verify that the transaction indeed took place and update the database accordingly. This record is public, shared by all, and it cannot be amended.
Cryptomining is when developers are rewarded with virtual currency for solving mathematical problems. Nikita has been able to build a computer farm on his mum's balcony which allows him to mine for virtual currency. He's making more than the average monthly salary in his town.

An initial coin offering pitching an Ethereum blockchain-based token for the fruit and vegetable tracking has shut down in what appears to be another ICO scam. Called Prodeum, the company claimed that it wanted to build a new price look-up code system that would allow consumers to track where their fruit and vegetables came from. According to a cached version of its page, “the PLU process is based on business needs and consumers are normally left out of the process. Prodeum’s goal is to bring detailed PLU system information to the consumer so they have a better understanding of where their food comes from.”
Cryptocurrency is a form of digital money that is designed to be secure and, in many cases, anonymous.
Cryptography is the science of providing security for information. It has been used historically as a means of providing secure communication between individuals, government agencies, and military forces. Today, cryptography is a cornerstone of the modern security technologies used to protect information and resources on both open and closed networks (Microsoft).
Let us follow the logic of things from the beginning. Or, rather, from the end: modern times. We are, as I am writing these lines, witnessing a complete riot against some class of experts, in domains that are too difficult for us to understand, such as macroeconomic reality, and in which not only the expert is not an expert, but he doesn’t know it. That previous Federal Reserve bosses, Greenspan and Bernanke, had little grasp of empirical reality is something we only discovered a bit too late: one can macroBS longer than microBS, which is why we need to be careful on who to endow with centralized macro decisions.
Apple co-founder Steve Wozniak revealed he bought bitcoin when it was at $700. Wozniak said he wanted to see what it was like to try to shop with bitcoin, at places like restaurants and hotels. "It's not that easy to do yet, but it's getting there. I was just playing around trying out how to buy and sell stuff and I didn't care I lost a ton of money, but now I'm way up," Wozniak added.
Blockchain is a transformational technology with the potential to extend digital transformation beyond a company’s four walls and into the processes it shares with suppliers, customers and partners. A growing number of enterprises are investing in blockchain as a secure and transparent way to digitally track the ownership of assets across trust boundaries and to collaborate on shared business processes, opening up new opportunities for cross-organizational collaboration and imaginative new business models.
The Ethereum network is an implementation of the blockchain concept. It takes the core blockchain structure and adds a programming language that is built inside of it. Like Bitcoin, it has over 5,000 full nodes and is globally distributed. Ethereum is primarily used to trade Ether, make smart contracts, and create decentralized autonomous organizations (DAOs). It’s also being used to secure blockchain applications and smaller blockchains.
The basics of blockchain are not terribly hard to understand, but let’s use a simple example to explain the principle. We all understand the concept behind money. If I want to pay someone with money, I can hand them a dollar bill, or four quarters, or a hundred pennies or whatever, and the deal is done. The other person has the physical, tangible object in their hand, so we don’t necessarily need a third party to confirm that the money has been transferred.
Political economist Francis Fukuyama predicted a future when social capital would be as important as physical capital, and that only those societies with a high degree of social trust would be able to create large-scale organizations capable of competing in the new economy.
Blockchain is the technological response to the massive loss of consumer trust brought about by the financial crisis of 2008. That trust matters, because as customer expectations continue to skyrocket, brands are struggling to keep up. The arrival of social and mobile-empowered customers has increased the pressure on companies to deliver truly great customer experiences.
