How Do Cryptocurrencies Work?

People are showing tremendous interest in cryptocurrency right now. If you have been doing online trading for a while and want to step into crypto trading, you have come to the right place. Here you will learn how a cryptocurrency works. Even though crypto is in the buzz, it’s still not understood by most people.

The Basics of Cryptocurrency:

A cryptocurrency is a form of digital money that runs on a brand new monetary system. Any centralized authority does not regulate it, nor is it tracked by a financial institution. Each digital currency today is decentralized by a peer-to-peer network called “blockchain.” Blockchain keeps track of all cryptocurrencies to make sure nobody gets to cheat the system. So, cryptocurrency is limited entries in the database that no one can change.

A network of peers is responsible for making a cryptocurrency. Each peer has a record of the complete history of transactions. They also know the balance of every account.

When Person “A” gives Bitcoin or any other type of cryptocurrency to Person “B,” he has to sign in with a private key. After that, the transaction is broadcasted in the network.

How Is A Transaction Processed?

Cryptocurrency is stored in digital wallets, and it exists on the blockchain. You can access these wallets from anywhere in the world as long as you have an Internet connection. A transaction in cryptocurrency goes through the following steps:

Transaction begins

Let’s suppose the currency in question is Bitcoin. Where’s how it begins. The user goes to an online exchange and coverts his money for bitcoins, which he now stores in a wallet.

Submit payments

Once he receives the bitcoins, a request is sent to the bitcoin network to make a purchase. Fortunately, multiple online merchants now accept payment in Bitcoins.

Verifying transactions

Miners are responsible for maintaining the master ledger, i.e., blockchain, for verifying each transaction. Verification takes about 10 minutes. Once it’s done, the data is broadcasted to all users, and the ledger is updated one final time.

To summarize, you first have to buy the cryptocurrency through a significant cryptocurrency exchange. Later on, when you decide to spend it, as you make a purchase, it goes through a verification process. Once the transaction is confirmed, it becomes a part of the record housed on the blockchain. The miners add the transactions to the public ledger after verification.

Who Are Miners?

Since there’s no central authority to manage the network, a mechanism is required to prevent abuse. If someone creates peers and spreads forged transactions, this could break the system immediately.

There is a rule that even the miners are required to demonstrate their skills to qualify for the job. They must find a hash that is responsible for connecting a new block with its predecessor. This process is known as “Proof of Work.”

It’s like a cryptologic puzzle that miners must solve. Once they are successful in finding a solution, they can build a block and add it to the blockchain. The miner has the right to add a coin-based transaction, which gives him bitcoins. It is the only legitimate way of creating or mining bitcoins.

Is Cryptocurrency Secure?

Anytime you are dealing with money, security is the utmost concern. Numerous security measures are designed into the cryptocurrency technology to ensure everyone in the network is secure.

Each wallet has a private key for its security, and only the rightful owner has access to it. Each wallet also has an address that is used for placing a transaction from one wallet to another. For a transaction to process, you need to sign in with your private key digitally. If someone else finds the address of your portfolio, they won’t be able to authorize the transaction without the key. However, if they have access to your key, they can approve the transaction on your behalf. It won’t be wrong to say that your transactions are as secure as your key.

Generally, no one can edit transactions after they have occurred. Also, cryptocurrency transactions are not susceptible to double-spending. It has increased safety over conventional methods, which makes cryptocurrency safer than other forms of currencies. The transaction cost in the case of cryptocurrency is higher, but it’s only to protect against problems like chargebacks and other frauds.


The future of cryptocurrency is bright, and we can only expect the list of cryptocurrencies to expand. Pretty soon, trading platforms will allow us to trade in crypto too.
