For secure cryptocurrency, blockchain is the right platform for you. With each block tied up in complex code, your currency is guaranteed to be safe.

This guide is designed to help you understand what blockchain is, its applications, and the pros and cons of blockchain. Let’s get started with these key points:

What is Blockchain?

The blockchain is defined as a safe and secure way for internet users to exchange digital information with one another.

Across this avenue, the transfer is guaranteed safe and cannot be tampered with. Unlike other forms of technology, it is not controlled by one party and functions as a form of cybersecurity.

With a blockchain in place, a community of individuals web-wide can determine how this information is shared, maintained, and amended.

How the Blockchain Works

Each data block that is added to the chain contains a cryptographic reference that leads back to the previous block.

This is what makes the blockchain tamper-proof. That reference is apart of the code that makes the blockchain secure.

Once the code is worked through, a random number called the nonce is revealed. That nonce along with other information produces a fingerprint or a hash.

The hash becomes encrypted making the blockchain secure. It must meet cryptographic requirements.

After this process, the block is completed and is placed on the chain. The only way to tamper with a blockchain is if each previous block was re-created and that is virtually impossible.

Blockchain Pros

Because a blockchain is not centrally controlled, it isn't subject to fraud the way most money transferring technology is.

Funds that are controlled by banks and other entities are far more likely to be infiltrated and destroyed.

With its complex system in place, the blockchain is indestructible.

Even if one portion of the network goes down, the rest of the blockchain will remain intact due to the fact that there are many people in place to keep the network running smoothly.

Blockchain Cons

Advanced technology such as this is not without its issues. Though the blockchain is extremely secure and requires specific data for the creation of each block, technicians have found the presence of inappropriate material within that data, data that was illicit. This data is easily encrypted alongside the authentic data making it difficult to detect.


The blockchain serves as the technology that keeps cryptocurrencies afloat. Among the most popular cryptocurrencies secured by the blockchain is Bitcoin.

Bitcoin was the first major cryptocurrency to utilize the blockchain structure back in 2009.

There are only 21 million bitcoins that are available for purchase. 17 million of those are in circulation.

Though Bitcoin is an innovative cryptocurrency, it has also been used for illicit purchases such as illegal substances and child pornography.

Bitcoin is maintained by collective known as miners. These miners control specially built computers used to ensure that transactions go through.

Bitcoin is not the only cryptocurrency that has adopted the blockchain platform. Other names include Ethereum, IBM, and R3.

A cryptocurrency called Ripple was specially created for the purposes of cross-border currency transactions. Their sophisticated technology and their ability to bypass the middlemen, allow for much faster transactions.

Blockchain Wallets

A blockchain wallet contains your cryptocurrency, much like a wallet in everyday life contains your cash and credit cards.

These wallets are specifically created for you. Your personal wallet will be programmed for your device only, keeping it safe and secure.

It will include your personal password as well. Your password will control access to your wallet.

Once your personal wallet is created, it will be encrypted twice and safely stored in a secure network.

On this secure server, your wallet is easily accessible across all of your devices. It is imperative that you keep your password in a safe place because it can't be reset.

To login to your wallet, you'll need your wallet I.D. and secure password. You may also need a two-factor authentication code.

Your I.D. will be composed of random numbers and letters. Your wallet I.D. can't be used to request or send funds to others.

Luckily, blockchain does provide you with a backup option. Your backup phrase will include 12 words and will include the encoded version of your wallet.

Whether you've switched your software or lost your password, this backup option will allow you to safely regain access to your wallet.

Blockchain Exchanges

A decentralized exchange is better than one that is centralized because users remain in control of their funds instead of third-party organizations.

With decentralized exchanges, users simply exchange their funds with one another. This eliminates the need for rules and regulations.

Central exchanges have been wracked with data breaches over the years. With central exchanges, there is no way to ensure that a user's funds are truly safe.

Therefore, any criminal could steal funds with the right approach and techniques. Decentralized exchanges are not subject to these data breaches due to the large network that controls them.

Traditional exchanges have speed and ease of use on their side. Due to the structure of decentralized exchanges, it's much harder to implement advanced features to them.

The process is often slow and complicated. This is why investors tend to lean toward traditional exchanges.
