Bitcoin is a cryptocurrency created in 2009 by Satoshi Nakamoto, a pseudonymous developer. Bitcoin is a peer-to-peer electronic currency system that enables payments to be transmitted directly from one person to another without going through a bank.

What distinguishes Bitcoin from earlier efforts to create electronic currency is that it is the first to properly overcome the issue of “double spending,” which is a concern associated with digital currencies since they live online by their very nature.

A digital currency holder may create a duplicate of it, transmit the copy to someone else to pay for goods or services, and keep the original to use or spend again.

Bitcoin also makes it easy to transfer money without the hassles that come with going through banks and other intermediaries, while keeping transactions quick, safe, and transparent. As a result, since Bitcoin is not held in a bank, no one can seize it.

Because all facts about Bitcoin transactions and supply can be examined by anybody using a blockchain explorer yet personal information is kept secret, it is transparent while still allowing anonymity.

Finally, it is quick and safe since it uses a globally dispersed peer-to-peer network with low transfer costs. Bitcoin overcame this obstacle by using blockchain, an inventive system for storing data in a safe, public, and transparent manner. 


Ethereum is a distributed ledger technology that enables users to create a variety of decentralized apps. It was first released in 2015 as an open software platform enabling users to build and distribute commercial, financial, and entertainment apps. This is a programmable blockchain that runs on a peer-to-peer network protocol.

As a blockchain platform with its own coin, it operates on a public blockchain network. Ethereum uses decentralized blockchain technology, much like any other cryptocurrency. Users may execute whatever code they choose instead of being limited to a few pre-defined activities. Users on the network may safely build, monetize, publish, and utilize apps and games.

The Ether coin is used as a form of payment on the Ethereum network. Users may, for example, purchase and sell things using bitcoin. As a digital currency in financial transactions, the Ether crypto has witnessed substantial price increases recently. As a store of value, it has also generated questions.

Furthermore, Solidity is Ethereum’s own programming language. Dapps are the term for all networked decentralized applications. Without the danger of outage, fraud, or third-party intervention, developers may write and deploy smart contracts and apps. More than transaction records for the ether currency is stored on the Ethereum blockchain. 


Dogecoin is a cryptocurrency that was founded as a joke in 2013 by two software engineers, Billy Marcus and Jackson Palmer, who previously worked at Adobe and IBM.

It was created as a sarcastic tribute to Bitcoin and the frenzy around cryptocurrencies at the time, with no other goal in mind than to make people laugh.

Palmer was skeptical about cryptocurrencies at first, and he joked about his new cryptocurrency endeavor on Twitter. However, he got excellent comments on social media, prompting him to purchase the domain

Meanwhile, Marcus was having difficulty publicizing his attempts to create digital money. He approached Palmer for permission to construct the software underpinning Dogecoin based on Luckycoin, which is derived from Litecoin.

On December 6, 2013, Marcus and Palmer formally debuted the cryptocurrency Dogecoin, with Palmer saying that the coin’s design was inspired by a viral joke in which a Shiba Inu dog was misspelled as “doge”. 

What is Blockchain and how does it work?

The term “blockchain” had never been heard of until Satoshi Nakamoto, Bitcoin’s pseudonymous inventor presented it to the public in 2008. 

While it’s simple to link the invention of blockchain technology to Satoshi Nakamoto’s introduction of Bitcoin, the idea existed long before the bulk of the world was aware of cryptocurrencies.

To summarise, blockchain technology has a long history that predates Bitcoin. Because grasping blockchain’s fundamentals – what it is and how it works, as well as its three major characteristics – decentralized, transparent, and unchangeable – may be challenging.

At its most fundamental level, blockchain technology is a record-keeping system. Every piece of data is saved in blocks that are connected chronologically one after the other, and as one block fills up, another is formed. The word “blockchain” comes from the fact that this new block is “chained” to the one before it.

A blockchain’s contents, hash, and preceding block’s hash are all included in each block. The data in a block on the Bitcoin blockchain, for example, include information about the sender, receiver, and the amount of bitcoin involved in the transaction.

The hash, on the other hand, functions as a fingerprint for each block. When the hash of a block changes, the block is no longer the same. This is important because each block holds a hash of the preceding block, allowing you to link them in the right sequence.

This is also what makes blockchain immutable: once a transaction is recorded on a block, no one can tamper with it or edit it. As a result, any future blocks that include the hash of the prior block will be invalid.
