Blockchain Technology Overview Seminar Abstract and Report

Introduction to Blockchain Technology

Blockchain is a distributed database that provides a secure and transparent way to keep records of transactions. It was invented as a solution to the problem of reconciling bitcoin payments. The blockchain is a shared ledger that can be used for anything from recording land titles to tracking inventory in supply chains.

Blockchain definition

Blockchain is a shared, immutable ledger that facilitates the process of recording transactions and tracking assets in a business network.

Here are some ideas on the practical use of blockchain technology

  • Creating a decentralized voting system using blockchain technology
  • Developing a blockchain-based supply chain management system
  • Implementing smart contracts for real estate transactions
  • Building a blockchain-based identity verification system
  • Creating a secure and transparent platform for charity donations using blockchain
  • Developing a blockchain-based system for secure and fast cross-border payments
  • Implementing blockchain technology in healthcare for secure and transparent medical data management
  • Building a blockchain-based system for secure and transparent online voting
  • Developing a blockchain-based system for secure and private messaging
  • Creating a blockchain-based platform for secure and decentralized file storage

What is distributed database?

A distributed database does not have a central authority. Instead, each node has its copy of the database and can be connected to other nodes through the network. Every participant in a distributed system has access to all data. In addition, because everyone can see what everyone else is doing within their copy of the ledger (i.e., they don’t need an audit trail), there are no privacy concerns with a distributed system like blockchain technology; however, there can be scalability issues if not enough users sign up for your service or product offering before launch time so you’ll want to keep this point in mind when planning out how many people will use your platform early on after launch date so that you don’t end up having too much demand on your servers during peak hours due t

Importance of public ledger

The blockchain is a public ledger of all the transactions that have ever occurred on it. Information is stored in blocks, which are linked to the previous block by cryptographic hashes. These blocks can only be added to by miners, who compete against each other to validate new data blocks and earn cryptocurrency as a reward. This process ensures that no one person or organization can alter information on the blockchain without detection; if they try, they will be punished by reducing their coin value.

The decentralized nature of blockchain makes it difficult for any one entity—such as an authority such as Facebook or Google—to control what information gets published online; instead, individual users decide what content should be shared publicly using their personal computers or phones connected directly into networks via Wi-Fi hotspots where no central server exists anywhere near them at all!

This transparency also means there’s no need for trust between parties when trading goods online; anyone can see exactly how many bitcoins someone has because every transaction appears publicly listed on this ledger entry which provides proof both parties agree upon its authenticity before exchanging goods/services among themselves via digital wallets (which act like accounts).

Blocks in Blockchain

Blocks are a collection of transactions added to the blockchain in a linear, chronological order. Each block contains information about the time and data contained within it. The process by which blocks are created and added is called mining or hashing (the latter term refers to using computer power to find solutions).

The first two steps of this process require miners—a group of users who provide their computing power for solving complex mathematical problems that verify transactions on the network—to solve these problems with their computers so that they can ascertain new transactions as well as add new ones into an existing block’s chain.

transaction history and ownership record

Blockchain technology, which uses a distributed ledger to track transactions and create permanent records, is a growing area of interest for many companies. The technology offers several benefits for businesses—from enhanced security and transparency to reduced costs associated with processing sensitive data.

Transactions on the blockchain are immutable: once they’re added to the chain, they cannot be removed or altered later on. This means that if someone tries to change their transaction history after it has been recorded in the chain (for example, by hacking into an electronic device used by one party), they will be unable to do so because all copies have already been made public on thousands upon thousands of computers around the world simultaneously acting as nodes in what’s called “the network.” This makes it very difficult for anyone who doesn’t control those nodes (or even know where they are) to access private information quickly without first learning how exactly how things work behind the scenes when using this type of technology.”

Blockchain technology can be used to reduce the cost of services.

Blockchain technology has the potential to reduce costs in several ways. For example, it can automate payments and transactions between different parties without relying on a central authority or middleman.

Blockchain technology is a distributed database that records all transactions using its currency (called ether). The ledger is public, meaning anyone can see what information has been entered into it; however, this does not mean that all users must agree on how things should be done. Instead of having one central authority controlling everything from beginning to end—which would require trust between parties—blockchain allows everyone involved in an exchange process directly connect via peer-to-peer connections across multiple computers located around the world at any given time


The future of blockchain technology is bright, and its applications are expanding. The benefits of this technology are many, and it will continue to grow in popularity because it has the potential to change everything from how we handle money to how businesses operate. All companies must understand how they can use blockchain technologies before they become outdated.
