Bitcoin developed first of its blockchain. To understand the nature of blockchain, understand first Bitcoin project. My post is to give all the keywords in blockchain by using an example of Bitcoin.

Let us ready...

How messages stored Example

  • The Bitcoin blockchain is one of the largest and most powerful blockchains in the world. It was designed primarily to send Bitcoin, the cryptocurrency. So, naturally, in order to create a message in the Bitcoin blockchain, you must send some Bitcoins from one account to another.
  • When you send Bitcoins from one account to another, a transaction history is recorded in the Bitcoin blockchain. After a transaction has been entered, the information can't be removed — your message will be around as long as Bitcoin is in existence.
  • The concept of permanence is powerful — it's the most important characteristic of any blockchain
  • You have several ways of adding extra little messages inside your transaction, but sometimes these methods don't always produce easily readable messages.
  • Embedding the data into the Bitcoin address ensures that it will be easily readable. You can do this by utilizing a Bitcoin vanity address. Think of a vanity address like a vanity license plate on a car. Six-letter Bitcoin vanity addresses can be obtained for free; longer ones cost money. The longer the vanity address, the more costly it is.

Types of Blockchains

Private blockchains

    • Private blockchains are great for developers because they allow them to test ideas without using cryptocurrency. The developers’ ideas can remain a secret as well, because the data has not been published publicly.
    • Large institutions can capitalize on the security and permanence of blockchain technology without their transactions being public the way they are in traditional blockchains.

      Public Blockchains

      • Public blockchains are available to general public. An example is buying an art piece from a vendor located in another country.

      Hybrid Blockchains

      • These are combination of public and private.
