Blockchain Development System

What is Blockchain?

The blockchain is a distributed database of records of all transactions or digital events that have been executed and shared among participating parties. Each transaction is verified by the majority of participants of the system.

It contains every single record of each transaction. Bitcoin is the most popular cryptocurrency, an example of the blockchain. Blockchain Technology first came to light when a person or group of individuals named ‘Satoshi Nakamoto’ published a white paper on “BitCoin: A peer-to-peer electronic cash system” in 2008.

Blockchain Technology Records Transaction in Digital Ledger which is distributed over the Network thus making it incorruptible. Anything of value like Land Assets, Cars, etc. can be recorded on Blockchain as a Transaction.

How does Blockchain Technology Work??

One of the famous uses of Blockchain is Bitcoin. Bitcoin is a cryptocurrency and is used to exchange digital assets online. Bitcoin uses cryptographic proof instead of third-party trust for two parties to execute transactions over the Internet. Each transaction is protected through a digital signature.?

Blockchain Decentralization

There is no Central Server or System which keeps the data of the Blockchain. The data is distributed over Millions of Computers around the world which are connected to the Blockchain. This system allows the Notarization of Data as it is present on every Node and is publicly verifiable.

Blockchain nodes

A node is a computer connected to the Blockchain Network. Node gets connected with Blockchain using the client. The client helps in validating and propagating transactions onto the Blockchain. When a computer connects to the Blockchain, a copy of the Blockchain data gets downloaded into the system and the node comes in sync with the latest block of data on Blockchain. The Node connected to the Blockchain which helps in the execution of a Transaction in return for an incentive is called Miners.

Is Blockchain Secure?

Nowadays, as the blockchain industry is increasing day by day, a question arises is Blockchain safe? or how safe is blockchain? As we know after a block has been added to the end of the blockchain, previous blocks cannot be changed. If a change in data is tried to be made then it keeps on changing the Hash blocks, but with this change, there will be a rejection as there are no similarities with the previous block.

Just imagine there is a hacker who runs a node on a blockchain network, he wants to alter a blockchain and steal cryptocurrency from everyone else. With a change in the copy, they would have to convince the other nodes that their copy was valid.

They would need to control a majority of the network to do this and insert it at just the right moment. This is known as a 51% attack because you need to control more than 50% of the network to attempt it.

Timing would be everything in this type of attack—by the time the hacker takes any action, the network is likely to have moved past the blocks they were trying to alter.

Blockchain project ideas

Here are a few project ideas for beginners looking to learn more about blockchain technology:

1. Cryptocurrency Wallet: Create a simple cryptocurrency wallet application that allows users to send and receive digital assets.
2. Blockchain Explorer: Develop a web-based application that allows users to view and search the transactions on a specific blockchain.
3. Smart Contract: Implement a simple smart contract on the Ethereum blockchain that can be used to manage a digital token or asset.
4. Voting System: Create a blockchain-based voting system that allows for secure and transparent voting while maintaining voter anonymity.
5. Supply Chain Management: Develop a blockchain-based system for tracking the movement of goods and services through a supply chain, providing greater transparency and traceability.
6. Decentralized marketplace: Create a decentralized marketplace using blockchain technology where the goods and services can be directly bought by the customers without any intermediary.
7. Identity Management: Create a decentralized digital identity management system that allows users to control their personal information and share it securely with others.

Peer to Peer Network – You must be aware of Bit Torrent and Tor. Both of these are built on peer to peer network design. A peer to peer network is a distributed application architecture that consists of computing devices connected to each other, without a central server.?

In centralized networks, the security is dependent on a single entity. If that central server is attacked, the security of the overall network is compromised. But a peer to peer network is more secure as there is no single point of failure.?

Distributed Ledger – A ledger is a system containing all the records of an input and output of a process. A distributed ledger is a data structure which is spread across different computing devices. DLT (Distributed Ledger Technology) is the technology that distributes records across all the users. DLT consists of 3 components – Data Model (current state of ledger), Language of transactions (which changes ledger state) and Protocol (used to build consensus). Blockchain is a type of DLT. This way the data is shared among all its users increasing transparency and avoiding corruption.?

Consensus – Consensus is a process of ensuring that all the different users in a blockchain come to an agreement regarding the current state of blockchain. There are several consensus mechanisms that are used by different blockchains to achieve consensus. For example, Bitcoin uses Proof-of-Work while Ethereum is moving from Proof-of-Work to Proof-of-Stake algorithm.?

Smart Contracts – Forget smart contracts and blockchain for a moment. Think about contracts in general. These contain some conditions which need to be fulfilled in order for some transaction (eg; money exchange) to occur. For example, if you are selling me a laptop, a contract will contain that I will be responsible to pay you only if the laptop works properly. Similarly, smart contracts are prerequisite conditions which need to be fulfilled for transactions to happen in a blockchain.

What is inside a blockchain?

A blockchain is a chain of blocks connected to each other. A block consists of four parts:

• Previous Hash, The timestamp, Nonce and Merkle tree root

Each block contains a cryptographic hash of the data of the previous block. The nonce is calculated by the miners by solving cryptographic puzzle to propose the next block in the chain. It is known as proof of work. The blockchain is said to be immutable because of its cryptographic properties. But this does not mean that changing the data is impossible. It means that it is extremely hard to change the data and any change can be easily detected. A Merkle tree is a binary tree with hash pointers. A Merkle tree is a structure that allows for efficient and secure verification of content in a large body of data. The advantage of using Merkle trees is that proving membership requires O(logn) steps. Also, in a sorted Merkle tree, non-membership can also be proved in O(logn) steps. The first block is known as the genesis block.?

Types of Blockchain There are different types of blockchains possible in the ecosystem.

1. Public – A public blockchain is also known as permission-less blockchain. Here, everyone can be a part of this blockchain and can participate by running as a node, by mining a block or by making transactions in the blockchain. Bitcoin and Lite coin are examples of public blockchains.
2. Private – A private blockchain is also known as permissioned blockchain. Here, there are restrictions on the participation as only selected individuals or member of an organization can be a part of the blockchain. Multichain and Hype ledger projects (Fabric, Sawtooth) are examples of private blockchain.
3. Consortium – A consortium blockchain are said to be partially-decentralized or semi-decentralized. It is controlled by a group of organizations unlike one organization as in private blockchain. The member organizations has the authority to participate by running as a full node, by mining etc. R3 and EWF (Energy Web Foundation) are examples of consortium blockchain.??

Case studies for Blockchain Technology?

1. Smart cards are used by Decentralized Autonomous Organizations (DAO) – There is no central management, but the smart contracts contain rules that describe how the company should operate. The organization’s management must be decentralized, resulting in a requirement for permission less blockchains.?
2. E-Voting-Privacy is one of the most essential public demands for E-Voting, as votes must be anonymous in order to avoid intimidation. However, in order to maintain the integrity of the votes, public verifiability is required. Because there are so many parties engaged in voting and they don’t trust each other, using blockchain technology is one of the more reasonable answers.?

Future Scope of Blockchain Technology

Finance, supply chain management, and the Internet of Things are just a few of the sectors that blockchain technology has the power to upend (IoT). The following are some potential uses for blockchain in the future:

• Digital Identity: Blockchain-based digital IDs might be used to store personal data safely and securely as well as offer a means of establishing identity without the need for a central authority.
• Smart Contracts: A variety of legal and financial transactions could be automated using smart contracts, self-executing contracts with the terms of the agreement put straight into lines of code.
• Decentralized Finance (DeFi): Using blockchain technology, decentralized financial systems might be built that support peer-to-peer transactions and do away with conventional intermediaries like banks.
• Supply Chain Management: Blockchain technology can be applied to a permanent record of how goods and services have been moved, enabling improved openness and traceability across the whole supply chain.
• Internet of Things (IoT): Blockchain technology may be used to build decentralized, secure networks for IoT devices, enabling them to exchange data and communicate with one another in an anonymous, safe manner. In general, blockchain technology is still in its early stages and has a wide range of potential applications.

Advantages of Blockchain Technology:

1. Decentralization: The decentralized nature of blockchain technology eliminates the need for intermediaries, reducing costs and increasing transparency.
2. Security: Transactions on a blockchain are secured through cryptography, making them virtually immune to hacking and fraud.
3. Transparency: Blockchain technology allows all parties in a transaction to have access to the same information, increasing transparency and reducing the potential for disputes.
