Every major cryptocurrency is established on a cryptographic system that makes use of a pair of keys;a public key and a private key.

In cryptography, a bit of information, normally a thread of letters or numbers that are kept in a file, which can decrypt or encrypt cryptographic data prepared over a cryptographic algorithm, is referred to as a key.In symmetric cryptography, these keyscan be used for encryption and decryption.

The key could be of distinct sizes and diversity, centering on the method; in every case though, how strong the encryption is, depends on how secure the key is being kept. How secure a key is, depends on its algorithm, size, generation, and method of key exchange.

With cryptocurrency being a fast-rising industry, it is catching the eye of a lot of people from different social standings.As with anything monetary, special care is to be taken. So, before one dabbles into it, it is vital to understand how the system works in order to avoid painful losses. Let's briefly look into some of its major security measures.

BLOCKCHAIN, WHAT IS IT?

A blockchain is a kind of database. It gathers information together in blocks or groups that hold an assortment of information. When a block is completely occupied, it is chained to another filled-up block, creating a chain of data referred to as the blockchain. Any new information that enters the system will be put in a fresh block that will join the chain when filled up as well.

The blockchain records any transactions done with cryptocurrency in such a way that it cannot be altered, making it difficult for a user's cryptocurrency to be tampered with or stolen.

WHAT IS A PRIVATE KEY?

This is a refined structure of cryptography that grants a user access to their cryptocurrency. It is an essential facet of bitcoin, and it can protect a user from losing control of their funds because of how secure it is.

A private key is the only solid way to prove ownership of a cryptocurrency.As long as you control a private key, you can spend the funds attached to that address and make any transactions at will.

You should not, under any circumstance, reveal your private key to anyone, as this could potentially lead you to lose control of your bitcoin.

Coins are not stored inside the private key but on the blockchain. However, keys are kept in a cryptocurrency wallet, and since coins aren’t stored in the keys, they are not kept in the wallet, which is a recurrent falsity.

WHAT IS A PUBLIC KEY?

This is known as a cryptographic code that enables users to acquire cryptocurrencies from one another.

When a transaction is initiated by a user, a special pair of public and private keys are generated. Each key is made up of characters that help in keeping the holdings of a user secure.

The public key can prove who owns a private key by verifying the digital signature. When a user initiates a transaction to send bitcoins, that transaction needs to be broadcast to the network for validation, and finalization, then it will be recorded on the blockchain.

A public key is formed from a private key so it will be used to prove the ownership of a private key before a transaction is finalized.

A public key generates a public address which two users reveal to each other in the process of a transaction. This public address is similar to a bank account number. Without this address, a sender cannot send funds to the receiver. The sender's public address, which is seen on the screen of the receiver will allow the receiver to confirm the number of coins he will receive from the sender.

The public key IS exposed to everyone on a network, and so a private key cannot be made from it. If a user lost their private key, they would also lose any Bitcoin or cryptocurrency attached to it forever. But if they were to lose a public key, they can generate another from the private key.

The public key is created on the first transaction initiated by a user. A new one is only generated if the old one is lost.

CONCLUSION.

The public and private keys ensure that your cryptocurrency is safe. With these security measures in place, you can relax and perform any transactions, spend your funds and whatnot without being overly concerned about losing your hard-earned coins.

The bitcoin market can only be profitable if you invest wisely.

Be shrewd and smart to get the full dividend from your cryptocurrency.
