First, you need to understand the difference between tokens and cryptocurrencies.
The term crypto token is regularly wrongly utilized conversely with the words cryptographic money and altcoins in the virtual cash world. Yet, these terms are unmistakable from each other. Cryptographic money is standard cash utilized for making or getting installments on a blockchain, with the most mainstream digital currency being Bitcoin.1 The digital money is the superset while altcoins (and crypto tokens) are two subset classifications.Altcoins are elective digital forms of money that were dispatched after the enormous achievement accomplished by Bitcoin.2 The term implies elective coins—that is—other than bitcoins. They were dispatched as improved substitutes of bitcoin with the cases to beat a portion of the trouble spots of Bitcoin. Litecoin, Bitcoin Cash, Namecoin, and Dogecoin are normal instances of altcoins.4 Though each has tasted shifting degrees of accomplishment, none have figured out how to acquire ubiquity much the same as bitcoin.Cryptographic forms of money and altcoins are basically explicit virtual monetary standards that have their own devoted blockchains and are essentially utilized as a mode for advanced installments. Then again, crypto tokens work on top of a blockchain that goes about as a mechanism for the creation and execution of decentralized applications and keen agreements, and the tokens are utilized to work with the exchanges.A easy recap; tokens are on a blockchain and easy to create, and cryptocurrencies and altcoins, are essentially specific virtual currencies that have their own dedicated blockchains.
Blockchain explained part one

Countless discoveries and inventions have been made throughout
our history. Some of the developments have been minor, some of
them have been major, some have been short-lived, and other
events have been more critical and longer-lasting. There have
been certain developments throughout our history that have been
so vitally important to humanity that they are considered the sole
factor behind all of humankind, collectively making progress and
taking a critical and everlasting step forward.
For example, consider how the creation of farming equipment and
fertilizers allowed for the exponential growth of food outputs from
fixed pieces of land. Without these inventions and discoveries, the
world would not have been able to support the explosive
population growth that we have witnessed across the globe. It

was only a few hundred years ago that scientists and economists
indicated the end of population growth, due to the fact that food
production just grew at numerical rates, doubling or tripling every
certain number of years, while populations grew at exponential
rates, expanding to the power of two or more during that same
period.
At the time, this meant that sooner or later there wouldn't be
enough food to feed everyone unless more food could be
obtained from fixed pieces of land every year. Fortunately, this is
precisely what happened. Science was able to deliver heavy farm
equipment, fertilizers such as ammonia, and other improvements
so that that food harvests could keep up with the population
growth rates. This allowed for more people to be sustained in the
same area of land as before. Without these developments, the
world would be a very different place today.
Similarly, the creation of antibiotics, penicillin, the introduction of
air travel, ocean freight, and the steam engine, and more recently,
the sharing of information in the Information Age that was made
possible by the invention of microchips and transistors, have all
changed the world irreversibly. As a result of these innovations
and discoveries, we are more connected, better off, healthier, and
have more accessible and cheaper access to goods and services
than ever before.

When it comes to the information age, things have progressed at
breakneck speed, ever since the first dot-com wave in the early to
mid-90s. Everything from the user interface tools and
technologies that have defined how we interact and interface with
technology. Everything from payment solutions to banking
solutions has dramatically changed over the last 20 years.
The same can be said for social networks and primary email,
along with the advancements that have been made in fields of
artificial intelligence (AI) and big data analysis, both of which have
an impact on everything from helping with governance to online
search. Collectively, we've gone from necessary solutions for all
of the above to have sophisticated software services that combine
various aspects of technology to deliver effective, robust, valueadded, and seamless services to billions of people around the
world.

However, with all the progress comes new challenges. AI, big
data, and the ability of governments to implement mass
surveillance initiatives, and the ubiquity of technology all around
have begun to pose serious ethical questions and technological
challenges. This leads to the question, where do you draw the line
between legal and illegal surveillance? How can we, as a society,
trust the data usage collection and manipulation practices of
companies and governments when they aren’t transparent. When
it comes to the role of government and big corporations and their
relationships with private users, where is the world headed?

t is with this exciting and challenging background in mind that
blockchain will be discussed. In recent years, blockchain has
become a popular technology and so much more than the latest
tech fad. It is, in the opinion of many subject area experts and
tech gurus, the next giant leap for humanity and something that
will have a significant impact on our children and us as the
farming and healthcare developments of the past had an effect on
our great-great-grandparents more than a century ago. We have
now entered the new Information Age.

How Did Cryptocurrencies Develop?
Bitcoin is the most well-known cryptocurrency on the market. It
has been the recipient of hype, fame, and publicity. The general
public has been fascinated by its extraordinary increase in value
over the last several years. They have been awe-struck by the
tales of significant wealth that has been generated with bitcoin, for
those who acquired it in its infancy, when it was cheap.
Despite its novelty, people quickly realize that bitcoin is genuine
money. In addition to bitcoin, there are many other
cryptocurrencies, who like bitcoin, have had massive increases in
their dollar value. Legitimate government and businesses are
pursuing an increasing involvement in cryptocurrency. Despite
critics, the market for these currencies is thriving.

Blockchains
Blockchains are digital ledgers and can be formally defined as a
continuously-growing list of records that are linked tougher and
secured using advanced cryptography. In more simple terms, a
blockchain is literally a chain of blocks. Each record in the list of a
blockchain’s chain is called a block that contains specific types
and pieces of information. Each block will usually include some
sort of pointer as a link to the previous bock, transaction data, and
a timestamp, which can take a variety of forms.
Another way to look at is that a blockchain is much like a
database where each entry is linked to the previous and next
entry. This means that the information contained within the
blockchain can't be changed, once a block with specific data is
added to the chain. Depending on the chain that you are looking

at, there are often useful tools for exploring that will allow you to
scan the transaction data.
Blockchains are resistant to being modified because of their
inherent design. This allows blockchains to record transactions
between different parties efficiently. These transactions are not
only verifiable but permanent as well. Once information is
recorded in a blockchain, the data cannot be altered after-the-fact
without altering the subsequent blocks by having the majority of
nodes on the network agreeing to the change.
This inability to change the data within a blockchain make illegal
or unfair actions almost impossible to carry out. If a hacker wished
to alter information within a blockchain, they would have to gain
control of every node. This security is one of the most useful
characteristics of the blockchain.
Since blockchains are designed to be verifiable and permanent,
they are especially suitable for recording events, maintaining
medical records, drawing up agreements, fundraising, and
keeping track of other documents.

Whether you are aware of it or not, you conduct business every
day, even if you don't work. At some point, everyone gets online
and initiates some kind of transaction. Whether it is purchasing
something from Amazon or buying something from iTunes, you
are engaging in the business of blockchain technology.
Even though the term “blockchain” is relatively new, the
technology has been around for about a decade. The digitized
ledger that Satoshi Nakamoto created in 2008 was the basis for
the spreadsheets that manage cryptocurrencies and other online
trading transactions. The technology is used in cryptography,
which is how text is coded on the Internet.
Cryptography is used in blockchain technology to create
distributed trust networks. This, in turn, allows any contributor to

the system to operate the transactions securely without having to
obtain authorization from someone else in the digital ledger.
These transactions are then verified, approved, and then
recorded in an encrypted block. This block is saved intermittently
and then connected to the previous block, which in turn creates a
chain.
Components of a Blockchain
Two main parts make up a blockchain. The first component is the
decentralized network. The decentralized network is what
facilitates and verifies the transactions that are made. Having
blockchains on a decentralized network means that the software
isn't limited to one computer system. Instead, it can be controlled
on multiple computer systems, and more importantly, it isn't
controlled by the government.

The second component is the indisputable ledger where the
transactions are processed and recorded in a location that is
secure. This security makes it almost impossible for someone
who is not connected to the chain to make changes or steal
information.
Since there can be numerous contributors involved in any
blockchain, any of the contributors can control the information that
is entered into the ledger. Since every transaction is processed
securely, and given a permanent time-stamp, it can become
challenging for another contributor to alter the ledger in any way. continue reading here; https://sakkemoto.com/2021/08/05/blockchain-explained-part-one/
