A Beginner’s Guide to Blockchain & Crypto

Blockchain technology eliminates the requirement for a trusted group to facilitate digital relationships and is the backbone of cryptocurrencies.

Blockchain is a type of ledger technology that holds and records data.

Blockchain is the buzzword that seems to dominate any discussion about the future of technology, from the capacity of cryptocurrencies to new forms of cybersecurity. The applications for the technology seem endless, but people aren’t entirely sure what Blockchain is.

In the old days, transactions were tracked in written ledgers and reserved in financial institutions. Conventional ledgers could be audited, but only by those with privileged access. 

How Does Blockchain Work?

Blockchain is fundamentally a way for individuals to share potentially valuable data in a tamper-proof manner. The type of data in question can vary based on the industry or purpose of the Blockchain. For example, a cryptocurrency-based Blockchain stores information on crypto currency data in question can vary based on the industry or purpose of the Blockchain. Cryptocurrency-based Blockchains, for example, provide information about cryptocurrency transactions, including the trader, recipient, and amount of currency exchanged. 

The Blockchain Process

  • A Blockchain transaction is requested and authenticated by the network.
  • A new block is created to represent the transaction.
  • Each new block is sent to all the nodes in the blockchain network.
  • Nodes validate the latest block and transaction. 
  • (In most cases) nodes accept a reward as a result of a proof-of-work system. 
  • The new block is counted on the Blockchain. 
  • The Blockchain update is distributed throughout the network.
  • The transaction is finished.

Advantages and Disadvantages of Blockchain

Blockchain Advantages

The main advantages of blockchain are their cryptographic security, crowdsourced oversight, and general stability. The data on a blockchain is virtually untouchable without network consensus, and the inherent uniqueness of each block mitigates the possibility of hacking and other malicious activity.

Blockchain Disadvantages

One of Blockchain’s biggest strengths may become its undoing without constant caution. Generally, network consensus is defined as 51 percent node approval, and 51 percent of attacks are theoretical threats derived from this model. In other words, if a hacker were to earn 51 percent control of a Blockchain’s network, they would be able to manipulate the chain’s hashing power, disrupt transactions, and compromise data.

Blockchain & Cryptocurrency Trends for 2021

The blockchain and cryptocurrency industries both produced noteworthy trends in 2021

Enterprise Blockchain

Blockchain has traditionally been predicated on open-source communities as opposed to systems where the chain is operated by a single entity; however, enterprise blockchain represents a new form of this concept.


These non-fungible tokens have generated quite a bit of interest this year. They are unique digital assets contained within blockchains. 


 this blockchain-based form of traditional financial trading has leaped to the forefront of cryptocurrency trends, leaving many wondering if its rapid ascent can be recaptured or expanded upon. 

How Safe Is Blockchain?

Blockchain’s nearly unhackable framework is developed to make factors like belief and safety an afterthought, but its inherent security remains a common discussion point. As a general rule, Blockchain is extremely hard to hack or modify.

As a result, in order to keep blockchains secure, nodes must remain vigilant as threats evolve to match blockchains’ innovative layers of security. Techniques like “Eclipse Attacks” take advantage of the constant communication between nodes that keeps blockchains functioning in order to overtake the network with a flood of false data and trick it into accepting false data or transactions. Fortunately, as blockchain is being adopted in more industries to encapsulate new types of data, it has resulted in tighter security boundaries and a greater sense of protection.
