Blockchain 101 & How to Build Your Own Cryptocurrency!

Blockchain101, the backbone of Bitcoin and cryptocurrency, enables digital information distribution across multiple nodes in networks, finding applications beyond crypto and now in other infrastructure.

What is Blockchain?

A blockchain is a decentralized, distributed, and incorruptible digital ledger used to record transactions across multiple computers. It is a network of nodes with a chain of blocks, each containing a ledger with a list of transactions, each cryptographically secure and linked to previous transactions for the resource it represents.

Blockchain is divided into two parts: blocks and chains. Blocks are transactions on the network, while chains link blocks with hashes. Changes in the previous block can break the chain, making it difficult to tamper with data.

Functionality of a Blockchain Protocol:

Blockchain is a chain of blocks with cryptographic hashes, timestamps, and transaction data, used as an open distributed ledger for secure and efficient transactions. Managed by a peer-to-peer network, it solves complex mathematical problems to validate new blocks. The data in a block cannot be updated retroactively without confirming the majority in the network, making blockchain technology highly secure and resistant to hacking.

101 Blockchain Prerequisites:

Let’s talk about some of the key blockchain prerequisites that will you help you understand this concept:

Public-key cryptography is used to verify user authenticity using a pair of public and private keys.

The user creates a signature with their private key, and the network uses their public key to validate the content.

Digital signatures use asymmetric key cryptography and provide authentication, non-repudiation, and integrity.

They ensure the message was not altered during the transfer, making them essential for secure communication.

Cryptographic hash functions are mathematical functions that transform input into output, ensuring no message can be recovered from the hash value. They also prevent collisions between accounts by ensuring no two or more messages can have the same hash, regardless of the data size.

Applications of Blockchain:

Blockchain technology offers numerous applications beyond smart contracts, including finance, contracts, identity, data storage, record keeping, medical, and more. It is an innovative alternative to traditional currency and centralized banking, making transactions almost impossible to hack.

Blockchain's main applications include cryptocurrencies, smart contracts, identity records, cloud storage, electronic voting, employee payroll, medical record keeping, and supply chain communication. Its distributed ledger makes it almost impossible to hack, transforming the way we handle financial transactions and the world.

Distributed consensus systems can quickly solve problem statements like trust issues in auctions. Blockchain applications can handle these issues by deducting token amounts from accounts and storing them in smart contracts on Ethereum. Bid transactions use a private key to sign, ensuring transactions cannot be reverted if the winner doesn't respond during payment. This makes it easier to handle events like unresponsive payments and trust issues in online auctions.

Ethereum can be used to develop online games like tic-tac-toe, where players deposit an X amount in a smart contract. Each move is recorded on the blockchain, and smart contract logic verifies each move. The smart contract decides the winner, ensuring no one controls the game, cheats, or commits fraud.

Bitcoin is the largest implementation of blockchain technology, with a wide range of applications based on distributed consensus systems. Ethereum smart contracts, written as transactions on the block, are the base for all other cryptocurrencies.

How to Create Your Own Cryptocurrency By Using Blockchain 101?

Cryptocurrencies can be created as coins or tokens, with coins having their own blockchain and tokens built on pre-existing networks. Coins require a team of developers, while tokens can be created quickly using other blockchains like Ethereum, BNB Smart Chain, Solana, and Polygon.

The choice depends on desired customization and utility, with costs varying based on work required, external developers, and time.

Ethereum and BNB Smart Chain are popular blockchains for creating digital currencies. Users can create tokens using established code or pay for coin creation services. Sidechains offer customization. Before creating a cryptocurrency, consider its utility, tokenomics, and legal status.

Choose the right blockchain, consensus mechanism, and architecture for development. Consider audits and final legal checks. Developing a solid cryptocurrency requires serious work and dedication.

What Is New In Blockchain Technology In 2024?

Blockchain is a crucial technological advancement, with applications in healthcare, publishing, and insurance. Its future trends include green initiatives, NFT platform development, and the metaverse. Innovative tools like digital assets, enterprise blockchains, and quantum computing are expected to transform the tech world.

Summary:

Blockchain 101, the backbone of Bitcoin and cryptocurrency, is a decentralized, distributed, and incorruptible digital ledger used to record transactions across multiple computers. It is highly secure and resistant to hacking due to its open distributed ledger and peer-to-peer network management.

Blockchain technology offers numerous applications beyond smart contracts, including finance, contracts, identity, data storage, record keeping, and medical. Distributed consensus systems can solve trust issues in auctions by deducting token amounts from accounts and storing them in smart contracts on Ethereum.
