Blockchain is a set of technologies that allow you to maintain a distributed register of data (Distributed Ledger), structured as a chain of blocks containing transactions. It is often defined as “an incorruptible digital ledger of economic transactions that can be programmed to record not only financial transactions, but virtually anything of value.” To validate the changes to be made to the registry, in the absence of a central body, the nodes must reach consensus (at least 51% of the nodes, ideally). Let's think of a system in which two people make an agreement: witnesses are needed to validate it and the same thing happens in the blockchain field.
The more nodes there are, the more the security of the system increases! Content Qatar Mobile Number List index: How does blockchain work? What are the characteristics of blockchain technology? Blockchain: from Bitcoin to the Internet of Value Tokens Digital citizenship Cybersecurity and blockchain How does blockchain work? Although it seems complex, in reality the functioning of the blockchain is quite simple: Each block usually includes a hash, which is a digital fingerprint of the new authenticated block that cannot be mutated or modified later. This hash, therefore, identifies the block uniquely and allows it to be linked to the next block through its identification. Each block contains several transactions, a hash that records information about the reference block, and another hash with information from the previous block. In this way, it is possible to create a chain by tying one block to another: if someone tries to modify the data, the hash and the entire chain break.
The transaction contains information relating to the recipient's public address, the characteristics of the transaction and the cryptographic signature that guarantees security and authenticity of the transaction. Shellrent In essence, the blockchain is a public and shared register made up of a series of clients or nodes: it is organized to update automatically on each of the clients participating in the network and each operation must be automatically confirmed by all the individual nodes through encryption software guaranteeing their digital identity. To encrypt the transactions carried out, great computing power is required as more and more blocks are required to authenticate the transactions: the nodes that provide the computing power are called miners and earn a fraction of new cryptocurrency (never owned before by others and not present in past transactions already recorded) for each block in which they participate.
