No central bank, state, or central authority has any power over Bitcoin, and its price is strictly defined by demand and supply dynamics in the market. Every transaction that occurs on the blockchain is transparent and is visible to everyone. Since 2009, cryptocurrency BTC has become the most popular and valuable cryptocurrency, accepted by hundreds of retailers and brands worldwide.

In order to produce a Bitcoin address, a private key, which is a randomly selected number, crypto is multiplied using an elliptic curve to produce a public key. This public key is then put through both the SHA-256 and crypto RIPEMD160 hashing algorithms.

imageVersion – Version number of the Bitcoin software Previous block hash – Reference to the hash of the previous block Merkle Root – A representative hash of all transactions included in the block Timestamp – The time at which the block was created Target – Proof-of-work algorithm for the block – The variable used in the proof-of-work process.

The SHA-256 algorithm is also used to produce the merkle root, which is then subsequently inserted into the block header. A comprehensive explanation of this aspect of the Bitcoin protocol can be found here: Merkle Tree & Merkle Root Explained.

SHA-256 has never been compromised and is considered one of the most secure cryptographic hash functions. It was developed by the NSA in 2016 following the breakdown of it's predecessor SHA-1. As a result, it's one of the most popular cryptographic hash functions in the cryptocurrency world. SHA-256 is a cryptographic hash function within the SHA-2 (Secure Hash Algorithm 2) family of hash functions. This article will cover how SHA-256 works and how it's used within Bitcoin specifically.

We’ll come to that shortly. But first do note that to ensure if the transaction is fully valid it is recommended that the transaction gets atleast 6 confirmations. To get confirmed 6 times it will take around 60 minutes because the block time of Bitcoin is 10 minutes.

You open your core wallet, or any light client; enter the recipient address along with the amount to be send, then choose the transaction fee and hit send. Let’s assume that you are going to send few Bitcoin to another address.

imageThe transaction data and so it is also called as transaction pool. As the name suggests it is a place where the data needs to be processed are stored. So what type of data are stored here? Mempool in short means Memory Pool. These transactions are waiting in the queue to be validated by miners and included in the next block on the blockchain. Mempool or Memory pool is a place which consist of all the recent and pending transactions that occurred on the blockchain network.
