Blockchain is a new type of digital wallet that can program economic and financial transactions to record not only financial transactions but anything of financial value. Bitcoin has been called "digital gold" and uses this technology. Few people may know what blockchain is, but Wall Street banks, IT organizations and consultants know blockchain and everyone is talking about it. Trying to remove the blockchain from Bitcoin is a difficult task. So we start with Bitcoin to better understand this technology. What is Bitcoin? The financial crisis of 2008 made many people lose their trust in banks. Many asked if banks are the best and most reliable money storage system in the world? Bad financial decisions by the world's major banks were disastrous and had dire consequences. Bitcoin, according to its statement, is considered a digital cash system, which allows online payments to carry out transactions online without the need to be in financial institutions and banks.
In other words, Bitcoin enables digital transactions without the need Israel Email List for a trusted intermediary. This technology on a global scale has made it possible to encrypt what financial institutions such as commercial banks or financial regulators or central banks do. What is blockchain? The definition of blockchain is something separate from Bitcoin. Blockchain technology provides a way for untrusted individuals and groups who do not know each other to agree on a shared digital history. Having a digital record is necessary, because digital assets or transactions may be fraudulent or duplicated. Blockchain technology solves this problem without having a trusted intermediary. What does blockchain do? As a peer-to-peer network, blockchain database information can automatically manage information between different groups. It does not need a single management and users can manage it.
In addition, blockchain networks can be used for smart contracts or scripts that run automatically. How does blockchain work? Every data that is put in the blockchain must be verified. Transactions are grouped together in blocks, hence the name blockchain. It is then reviewed by computers on the network. When a computer connects to the network as a node, they receive a copy of the blockchain. This means that all information stored on the network is transparent, that is, public by default. This means that all the data in the blockchain cannot be deleted or corrupted. However, this does not mean that you can see who has transacted. For example, with Bitcoin, the public can see that someone is sending money to another person, but there is no information about the transactions between the two people. It is also unhackable because it does not have a centralized system, instead it is hosted by millions of nodes around the world instead of using a central location. How secure is blockchain? While no system is unhackable, the simple blockchain topology is the most secure today.
