Will Blockchain's Economy and Administration Revolutionise? What is a blockchain? A blockchain is a complete and unchanging transaction history of all transactions of a decentralised community that everyone who is part of it agrees to. The word blockchain first fell in connection with Bitcoin as a decentralised network for payments in the digital currency of the same name. The blockchain describes an underlying technology in which all transactions are publicly and unchangeably recorded. This transaction history is updated periodically. Each participant in the decentralised community accepts it as a reality, stores it on their computer, and can thus ensure at any time that no one can duplicate expenditure, as this would lead to a conflict in the transaction history elsewhere. A peculiarity of blockchain technology is that it has solved the "Double Spending Problem". Double-spending means something that can be doubled, and by 2008, only one central institution was considered to be sustainable. Double Spending can best be understood using the example of an image on a mobile phone. When I upload it to Facebook, I made a copy of it and I can upload it to Instagram, for example. So I used my picture "double". This effect made it impossible to establish a trustworthy, decentralised digital currency by 2008.
