Blockchain technology is a structure that stores transactional records, also known as the block, of the public in several databases, known as the “chain,” in a network connected through peer-to-peer nodes. Typically, this storage is referred to as a 'digital ledger.

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.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

2. What is Blockchain?
Blockchain is a distributed database but its stored devices are not connected to a shared server.
In blockchain list of records is stored as blocks and they are linked by using cryptography.
Hence we can say that blockchain is a digital record and is used for recording transactions made with
cryptocurrencies such as bitcoins.
If we add a new block it can be linked with the previous block with the help of a cryptographic block
generated from the previous block. By doing so the block is permanently recorded and it is not
broken.
In blockchain previous transactions alteration is very difficult because all subsequent blocks also
need to be altered. We can say that blockchain is the purest peer-to-peer database that is immutable.

3. Definition of Blockchain
It is an open distributed ledger that
record transactions between two persons
efficiently and in a verifiable and
permanent way.
Each transaction is secured with a digital
signature that proves its authenticity.
Every block contains a cryptographic hash
of the previous block, a time stamp and
transaction information.

4. Origin of Blockchain Technology
The blockchain was created by a person (or group of people) using the name (or
pseudonym) Santoshi Nakamoto in 2008 to serve as the public distributed ledger for bitcoin
cryptocurrency transactions, based on previous work by Stuart Harbor, W. Scott Storentta,
and Dave Bayer. The identity of Satoshi Nakamoto remains unknown to date.
The implementation of the blockchain within bitcoin made it the first digital currency to solve
the double-spending problem without the need of a trusted authority or central server. The
bitcoin design has inspired other applications and blockchains that are readable by the public
and are widely used by Cryptocurrency. The blockchain may be considered a type
of payment rail.
Private blockchains have been proposed for business use. Computerworld called the
marketing of such privatized blockchains without a proper security model “Snake
Oil"; however, others have argued that permitted blockchains, if carefully designed, may be
more decentralized and therefore more secure in practice than permissionless ones

6. Purpose of Blockchain
Blockchain uses an online ledger which is very secure.
There is no third-party interference.
It used distributed ledger which is very transparent.
It is a digital world offering many new tools and there are many centralized administrators.
Since there is no third-party guarantee cost is very low.

7. Blockchain in Cryptocurrency
The term blockchain is often used to refer to
cryptocurrency. Cryptocurrency is a medium of exchange
such as US dollars.
It is just an application in the form of e-currency using
blockchain.
It is not governed by any financial institution.
The main difference between blockchain and
cryptocurrency is that cryptocurrency is created and held
electronically in forms such as a virtual wallet.
It is decentralized and it is not governed by anyone
whereas blockchain is an advanced record and it has all
information related to cryptocurrency exchanges over a
shared system.

8. Blockchain Examples
Bitcoins and Cryptocurrency are the widely used blockchain technology.
Based on blockchain cross gaming video games are developed for example B2Expand.
Social Engagements such as match pool use this technique.
Retail products can be purchased and if there is any malfunction blockchain helps to access information
regarding the product.
Blockpoint simplifies the payment system and allows Mobile wallets, gift card, and another point of scale
functionality.
Food industry Network from farmers to groceries is very complex and blockchain makes it easier by
tracking down foodborne illness challenging.
Real estate also uses blockchain technology by allowing anyone anywhere in the country to invest in real
estate.
