Let's start with the basics. The Blockchain is the single most important technology you will need to understand if you are interested in the technology of the future . Blockchain is a distributed ledger which is basically the worldwide collaborative sharing of immutable records. It gives control and privacy to all parties to share.
In the early days of Bitcoin, the Blockchain was referred to as the "block chain" and used as a block database or storage system to distribute private keys that secure the blockchain. As the technology evolved to a greater extent, this same term became "The Blockchain". This phrase is a bit confusing at first, but it soon becomes clear.
Blockchain is not simply a specific invention; it is a concept. It is an industry, a paradigm and a new way of doing finance, banking, commerce and business.
The core concept of the Blockchain is essentially a public ledger of ownership and transferring of value. It provides freedom from centralization (A major benefit to having a decentralized system), it provides confidentiality and integrity (since it is not just private and shared), and it is not subject to control by any one person or entity.
The Blockchain is the simplest mechanism for a verified record of information to be held by multiple parties. It is also often referred to as the distributed public ledger or distributed database.
The Blockchain is distributed public ledger that is accessed by all nodes participating in the system. In other words, it is open to anyone who has an internet connection, regardless of their location, who can read, update, and maintain the Blockchain, from anywhere in the world. Every person who owns a node of a Blockchain is referred to as a user of the Blockchain. Miners, who are also called nodes, are those entities that have the power to add entries and updates to the Blockchain and are assigned a single identity by the entire system.
Blockchains are also referred to as block chains, chains, or ledgers. In other words, they are like a chain of information that is based on the principles of cryptography.
Cryptographic keys are numbers used to authenticate and validate the integrity of a message. The public key, or hash, is the number that's shared by all users on the network; the private key is not shared and only known to you.
You can think of the public key as the address of a recipient's inbox on your message. Every time you send a top cryptocurrency, the sender's public key is published in the blockchain and your recipient's public key is also published. Both your public key and your recipient's public key remain publicly available even after you've closed your account and deleted all of your messages.
The private key is the secret number that's used to encrypt the sender's message. It's like writing your message in code and then putting it in a sealed envelope.
You can think of the private key as the password that allows you to access your messages. If you choose to use a password instead of a cryptographic key, someone who has access to your private key can decrypt your message and then you'll have to change your password. With cryptography, the message remains secure regardless of how it was encrypted.
There are many reasons why people are so excited about the Blockchain. One of the more important and very important features of the Blockchain is that it is available globally. Because of its network effect, the Internet has been able to scale to support an even larger population.
When thinking about the benefits of the Blockchain, it is important to keep in mind that it is a new and powerful technology that will impact the entire world economy. As this technology evolves, its applications will surely continue to expand.
