Hey all, Welcome to Geeksforjobs

introduction :

Interested in making digital payments? Tired of carrying a bunch of cash? Disappointed from going to the bank? Feeling bad paying more commissions for a transaction? If yes, then you are welcome to read some interesting facts about bitcoin.

Bitcoin:

Bitcoin was introduced in 2008 by a person or group named Satoshi Nakamoto. And it was launched in 2009 as open-source software.

Transactions are carried out from one user to another without having to send on the basis of central bank or an administrator

peer to peer :

They have been made for peer to peer bitcoin networks without the use of intermediates. All transactions are recorded in a public distributed bookkeeping called a blockchain.

Bitcoins can be earned in two ways. The first is to exchange a bitcoin and buy it with other currencies. The second method is by mining.

Miners are people who are involved in the transaction process in a peer-to-peer network.

Critic:

Everything like bitcoin to some critics and acclaim.

Critics have great potential for its use in illegal transactions, large amounts of electricity used by miners, theft from exchange, and price volatility.

First transaction:

Cypherpunk Hal Finney downloaded bitcoin software at the release date. He earned around 10 bitcoins from Satoshi Nakamoto. And Finney became the first person to get bitcoins.

Nakamoto mined around one million bitcoins and disappeared in 2010. He handed over control to Gawain Anderson.

symbol:

The symbols used to represent bitcoins are BTC and XBT. And some options for low bitcoins transactions are mBTC and sat.

Blockchain:

Blockchain is an implementation in the form of a series of blocks. Each block contains the hash code of the previous block of the genus block of the chain.

Nodes:

Network of nodes running bitcoin software to maintain the blockchain. Each node stores its own copy of the blockchain.

In varying intervals of time-average for every 10, minutes a new group of accepted transactions are created called blocks and added to the blockchain and published very quickly.

transaction:

When a user sends bitcoins, he adds the address and the amount to be sent to that address. They also add a total unqualified amount to prevent repeated transactions while making multiple transactions.

Transactions can have multiple inputs and outputs.

Transaction Fee:

Miners can select transactions, and prioritize transactions based on storage size. Transaction fees depend on per byte. Its size depends on the number of inputs and outputs.

private key :

Selecting a random valid key and compensating it to create a corresponding bitcoin address.

If the private key is lost, the owner will lose ownership. The private key must be kept secure to improve the chances of secure transactions.

hash map :

Each block contains the OSHA-256 cryptographic hash of the previous block, thus linking it to the previous block and giving the blockchain its name.

Conclusion:

The price of bitcoin changes from time to time, so investing in it becomes a misleading thing. Bitcoins are accepted as legal.
