![]() And the word “acyclic” means that past transactions cannot verify future and present ones. When you want to make a transaction via DAG, you have to verify two previous ones. Imagine many chains intertwined with each other. ![]() Instead, it's more like a tree, or a graph. Talking about cryptocurrencies, and more specifically IOTA, Tangle is a system of records of transactions that are not gathered in blocks or organized linearly, like in the blockchain. In further detail, DAG is an architecture and a mathematical model used to organize, record, store, and verify information. This is different from the blockchain structure, but it does the same thing - builds an independent and self-managed network of transactions. Tangle is just another name for DAG, used in IOTA (Internet of Things application). Does it sound more familiar? Let’s see what is Tangle, how it works, and why many experts think this is the future of storing and verifying information. If you have not heard this term, then think about this one - Tangle. This stands for the directed acyclic graph. One of the technologies that seem the most interesting to me is called DAG. And if you still do not know about it, this article will bring you up to speed. Can you imagine a cryptocurrency with no transaction fees at all, where there is no need for miners or anyone else to maintain the network, where you can send and receive the tiniest amounts of coins and shares? Recently, that dream has come true. Or, it cannot exist without miners, and thus - the fees are inevitable.Īnyway, after some years of development and evolution, other approaches to data verification and protection were invented. For example, the ledger gets heavier and slower with every new transaction, as the blockchain grows. ![]() ![]() With time, people have realized that this system is not ideal, and there are problems to be solved. Why were people so obsessed with the blockchain? Because this system guarantees that no one, no matter how powerful or rich this person is, can tamper with the information encoded within the public ledger. Firstly, as you know, it was implemented in the first cryptocurrency, Bitcoin, but later, it came to banks, security providers, insurers, farmers, governments, etc. The idea of recording the information without any ability to change it afterward was brilliant. A new milestone in the world of money, security, e-commerce, and the Internet as a whole - it is literally everywhere now, and modern business utilizes it worldwide. Blockchain was a real technological breakthrough back in 2008. ![]()
