In the time that Bitcoin (BTC) initially became popular in 2009, a small percentage of people knew the concept behind it or the ripples it could create both technologically and financially. Blockchain technology was an entirely new concept and, like many new concepts, was not widely understood. In 2018, blockchain was an issue of great interest: although it's tied to cryptocurrency in many people's minds, it's an independent concept upon which cryptocurrency could be built. This article will explain the workings of blockchains and, equally importantly, what happens when blockchain ends and the technologies built on it begin.
When Bitcoin (BTC) first began to become famous in 2009, only a small portion of people knew the idea behind it and the ripples it could cause both financially and technologically. Blockchain technology was a new concept that, like other new concepts, was not widely accepted. Blockchain technology in 2018 technology was an area of intense attention: even though it's connected to cryptocurrency in many minds, it's a separate concept on which cryptocurrency could be constructed. This article will outline the functions of blockchains and what happens after blockchain is finished, and the technology built upon it starts.
Every block of data within this system has four components of information:
Timestamp- The date when the block was made.
Transaction Root The details of the transactions in this block, i.e. this part in the ledger. The amount of information stored in this section may differ significantly. In Bitcoin the amount will be around ten minutes' value of transaction. Other implementations have shorter windows.
Previous Hash It is the is the hash of the block which was the most recent within the chain. This is the way that chains are linked. After a particular block is processed its hash will be the Previous Hash of the subsequent block in the chain, making it possible for the records of the past to be linked up and traversed.
Nonce- A cryptographic term that refers to an arbitrarily calculated value that can only be used once in the course of a transaction. The reason for this will be explained in more detail in the future.
The hash value of the block - that is the value of the previous hash in the next block - is the hashed value for all the data contained in these four pieces taken together.
