And I am sharing this to help everyone to learn about blockchain technology.
A blockchain is essentially a distributed database of records or public ledger of all transactions or digital events that have been executed and shared among participating parties. Each transaction in the public ledger is verified by consensus of a majority of the participants in the system. And, once entered, information can never be erased. The blockchain contains a certain and verifiable record of every single transaction ever made. To use a basic analogy, it is easy to steal a cookie from a cookie jar, kept in a secluded place than stealing the cookie from a cookie jar kept in a marketplace, being observed by thousands of people. In the report, it distinguishes between multiple types of blockchains and explains the two biggest platforms, namely Bitcoin and Ethereum. While introducing those two platforms we explain the most important technology and algorithms used such as proof of work concept. Some of the security issues and solutions are also covered. We conclude with some concrete Ethereum based applications that demonstrate the usage of blockchain technology beyond cryptocurrency and illustrate current developments in this field.
27 MAJOR BLOCKCHAIN APPLICATIONS AND REAL-WORLD USES.pdfYunusAdam1
Blockchain applications now go well beyond money and bitcoin. Technology is having an impact across a wide spectrum of organizations, from contract enforcement to government efficiency, due to its ability to promote openness and justice while also saving corporations time and money. This approach offers a much broader variety of applications.
Many people focus on cryptocurrencies, their speculative value, and how they may be utilized to make – or lose – a lot of money quickly when it comes to blockchain. This, however, does not do justice to the blockchain's incredible technology. Current and future breakthroughs have the potential to alter many industries.
One of the most hyped IT buzzwords to have emerged in the last couple of years. Blockchain has found its way into major media headlines on a near-daily basis, but a year and a half ago, it was a word used by a relatively small number of people to describe the peer-to-peer distributed ledger technology.

Concept of Blockchain Technology - How Does It Work (1).pdfcoingabbar
There are lots of adverse effects of the Covad-19 Pandemic but the pandemic also spurred positive transformations in life sciences: the digitization of everything. This also exacerbated-existing concerns about how to handle data and track providence between partners in the value chain.
Additionally, social distancing and virtualization of work created new challenges in collecting, managing, and sharing data. Blockchain appears to be one of many solutions experts are keeping eye on. Blockchain seems to be the most prominent solution as it can play a significant role in supporting digitization.
Blockchain is a technology and not cryptocurrency that’s why even banks are ready to adopt it in their system but before going through all the adoption processes we all need to understand the concept of Blockchain technology.
What is a Blockchain?
A blockchain is referred to as a dispensed database that is shared among the nodes of a computer network. Being stored in the database, a blockchain keeps the information electronically in digital format. Basically, Blockchains are best known for their important role in cryptocurrency systems, like bitcoin, for balancing secure and decentralized record transactions. However, the variation under a blockchain is that it assures the fidelity and security of a record of data and executes trust without the requirement for a trusted third party.
Usually, a database structures its data into tables, whereas a blockchain, such as its name suggests, structures its data into chunks (blocks) that are powerful together. This data structure naturally makes an immutable timeline of data when performed in a decentralized behavior. Once a block is filled, it is set in stone and becomes a part of this timeline. So, each block in the chain is given a correct timestamp when it is added to the chain.
How does a Blockchain Work?
The aim of blockchain is to enable digital information to be stored and distributed, however, not edited. This is how a blockchain is a foundation for continualledgers or records of transactions that cannot be modified, deleted, or damaged. This is the reason blockchains are also known as distributed ledger technology (DLT).
The very was first proposed as a research project in 1991, where the blockchain concept predated its first widespread application in use: Bitcoin, in 2009. From the past years, the use of blockchains has exploded through the creation of several cryptocurrencies, decentralized finance (Defi) applications, non -fungible tokens (NFTs), and smart contacts.
Blockchain Decentralization
Blockchain gives access to the data held in the database to be laid out among several network nodes at multiple places. It not only builds monotony, however, also maintains the dedication of the data stored therein - In case someone tries to fix a record on an occasion of the database, whereas the other nodes would not be adjusted and this is how it prevents a bad actor from doing so.
Blockchain can be used across the whole manufacturing industry to address all different types of projects and stakeholders. Its value to the manufacturing vertical is promising as Industry 4.0 continues to grow.
The blockchain is the technology the underpins digital currency (Bitcoin, Litecoin, Ethereum, and the like). The tech allows digital information to be distributed, but not copied. ... You may hear it described as a “digital ledger” stored in a distributed network.

3. ABSTRACT
Blockchain Technology is a remarkably, decetralised transparent way of recording
lists of transactions. Their best-known use is for digital currencies such as Bitcoin.
Blockchains shift some control over daily interactions with technology away from
central elites, redistributing it among users. In doing so, they make systems more
transparent and, perhaps, more democratic. That said, this will not probably not result
in a revolution. Indeed, the governments and industry giants investing heavily in
blockchain research and development are not trying to make themselves obsolete, but
to enhance their services. There are also some wider issues to consider. For example,
blockchain's transparency is fine for matters of public record such as land registries,
but what about bank balances and other sensitive data? It is possible, to identify the
individuals associated with transactions. This could compromise their privacy and
anonymity. While some blockchains do offer full anonymity, some sensitive
information simply should not be distributed in this way. Nevertheless, although
blockchains are not the solution for every problem and even if they will not
revolutionise every aspect of our lives, they could have a substantial impact in many
areas and it is necessary to be prepared for the challenges and opportunities they
present
4. Problem Statement : To know about what is
latest blockchain technology, how its beneficial
and useful than current technology.
Reason: To remove the intermediates, third
party role their interaction, their processing
charges, to maintain confidentiality of
transaction.
Purpose of the System:
Blockchain has the potential to truly disrupt
multiple industries and make processes more
democratic, secure, transparent, and efficient.
What….? , Why….? , How….?
5. INTRODUCTION
Blockchain :
“The blockchain is an incorruptible digital ledger of economic
transactions that can be programmed to record not just financial
transactions but virtually everything of value.”
1st
Generation of digital revolution brought us the IoT.
And 2nd
is Blockchain tech – is bringing us the internet of Value.
It is essentially a way of keeping records. Any kind of records:
Records of financial transactions in case of bitcoin, or records of legal
contracts, sensitive patient information in the medical field and so on.
“Blockchain is basically good for protecting any kind of asset and
transaction that needs to be tamper-resistant.
This includes transportation, voting, medical records, reputation,
identity, IoT. In fact the entire Internet Archive could be kept on a blockchain
6. LITERATURE SURVEY
Blockchain dose not have specific history as its new technology, but
according to use we can point out the draw back of existing
system,
E.g. Bank Transaction,
- You need valid account with all KYC verified.
- Need beneficiary details like , name, IFSC code, acc no,
- Transaction should be proceed under bank,
- Required few day, Service charges.
- We can not send money to strangers.
This all kind of drawbacks are overcome by the blockchain
technology. Also because of cryptography , Hashing and
Decentralization thousands of companies using technology in
their sectors.
7. What kind of Block
………
Each Block Contains :
A Hash or unique ID, which consists of a random set of unique numbers.
A hash number from the previous block, which assigns the chronological order
for the ledger.
All the transactions included in the block. That could be just one or one thousand
of transactions.
A public key for the sender and the receiver to identify a certain transaction.
A Block contains Digital signature – using transaction details, private key,
timestamp, or any other relevant information
Block 1 Block nBlock 2
8. HOW IT WORKS
Hashing (SHA-256 o/p- 256 bit or 64 bit char
long)
Public /Private Cryptography
Decentralization through P2P network.
Blockchain Data Structure.
9. CONT…
Hashing : In simple terms, hashing means taking an input string
of any length and giving out an output of a fixed length. In the
context of crypto currencies like Bitcoin, the transactions are
taken as an input and run through a hashing algorithm (Bitcoin
uses SHA-256) which gives an output of a fixed length.
Let’s see how the hashing process works. We are going put in
certain inputs. For this exercise, we are going to use the SHA-256
(Secure Hashing Algorithm 256).
10. Distributed : Blockchain is essentialy database of all
transaction happning in the nw the data bases are public and not
own by any party and its distributed that is its not own bye any
one instead its stored on many computers across world.
Synchronization : data base countinuosly sync to mak eit upto
date
After a transaction the recored is added in pblock and added in
public ledger which any one can see.
The technology can work for almost every type of transaction
involving value, including money, goods and property.
Companies racing to adapt blockchain include UBS, Microsoft,
IBM and PwC. The Bank of Canada is also experimenting with
the technology.
13. EXAMPLE : BLOCKCHAIN AND
BITCOIN
If Internet change the way we transfer information then
Blockchain changing a way we transfer value.
BlockChain can be applied to many business process.
Buyer and seller can interact and transfer value direct to each
other over the internet without any third party inter
mediatory .
Blockchain not underlying any private or government body.
14. The first application of blockchain is Bitcoin ,
Its P2P decentralized system you don’t need to register to
any particular company or to hand over your details.
Once you have wallet, you can generate unique address,
Parties in network verify a transaction , using this we can
not use same bitcoin twice, Bitcoin and theire bae units
must be unique to be owned and have value , to achive this
nodes in N/w create and maintain a history of transaction
for each bitcoin by using Proof-of_work mathematical
problem.
Distributed Ledger :
26. CONCLUSION
Blockchain, mostly known as the backbone technology behind Bitcoin, is one
of the hottest and most intriguing technologies currently in the market. Since 2013
Google searches for “blockchain” have risen 1900%. Similar to the rising of the
internet, blockchain has the potential to truly disrupt multiple industries and make
processes more democratic, secure, transparent, and efficient. Entrepreneurs,
startup companies, investors, global organizations and governments have all
identified blockchain as a revolutionary technology. As its a decentralized and the
cryptographic technology no one can hack it, hence their are lots of areas Private,
governments peer to peer sector the blockchain is useful. As example of bitcoin it
removed role of Bank that is middleware between two parties, this is more secure
trustable technology and because of many benefits it will take place in different
areas, to make their operation transparent, secure, efficient.
