Blockchain Development
How does it work
You couldn’t fail to have noticed how blockchain has integrated itself into our lives over the past decade. Since the arrival of Bitcoin, blockchain technology and development have been adopted across many industries. Financial experts believe blockchain will likely grow to become a fundamental technology behind most central bank digital currencies (CBDCs). But there are still many people left baffled about blockchain, how it works, and why its popularity is growing fast.To put it simply in a way that people can understand, blockchain is a type of database. A database is a set of information organised into a logical order. Each time you go online to access your social media, connect to your online bank account, or look something up on Google, you link up to a database.Databases make it easier for us to access, update and manage sets of digital information.What makes blockchain secure?
Each added data block in the chain is individually encrypted using the hashing method. Hashing converts one value into a string of characters of fixed length. Hashing is a valuable way to validate data, but it also stores it in a way that never reveals the original data.The structured way in which these data blocks are created is the critical property that keeps the data in the blockchain protected against outside manipulation.For example, take a Google Doc user with shared access to a file. They could easily manipulate the data sets, which would be updated to all shared users, presenting the new false data as valid.
Blockchain deals with this issue in a revolutionary way. Each data block in the chain comprises three elements: the transaction data, a randomly generated 32-bit nonce number created when the block is made, and the hash. Because each block is time-stamped and nonce-stamped with hash and linking to the previous block in the chain, it cannot be overwritten.
How does blockchain work?
Blockchain is a distributed database. You have a line of computers in a network (nodes) that run identical data copies. Should one copy on a node become compromised, the blockchain network’s redundancy will ensure that it won’t crash and continue to run. The nodes sync together to update the database, so that data will be ignored if any nodes pass on flawed data that doesn’t match up with the rest of the nodes. Blockchain technology builds the database in chronological order, with each data block getting a time-stamp, which forms the chain. If any single data block in the chain were tampered with, a new chain would branch out and form, creating a false database that the network would dismiss.
Ethereum (ETH) smart contracts and Apps
Following bitcoin’s success, Ethereum has risen to become the world’s second most important blockchain platform. Masterminded by Vitalik Buterin, a Russian-born developer who was once a member of the bitcoin community, he proposed to use the network to generate and manage various collaborative and decentralised applications (dApps). However, his requests were rejected. Buterin then developed and launched his own projects in 2015 that resulted in the formation of Ethereum.
This is a digital platform of blockchain technology and its own cryptocurrency known as Ether.The team launched a new function called Smart Contracts. These collaborative solutions allow you to create a traditional contract, such as a sales contract, but it needs no third party to validate and execute it. Smart Contracts are programmed in computer language between the parties involved and then automatically executed. Traditional contracts need validation from a third party before they can be acted upon. Ethereum has become a very promising blockchain platform for businesses because of its ability to deliver great value and security. It is especially appealing for business transactions because of its transparency, efficiency and low cost.
