Blockchain Revolution Meaning And Facts

What Is Blockchain And Distributed Ledger Technology?

Distributed Ledger Technology (DLT) allows data to be recorded on multiple computers called “nodes.” Each user of the blockchain can be a node, but operation requires a lot of computer power. Nodes review, approve, and store data within the ledger. This differs from traditional record-keeping methods, where data is stored in a central location, such as a computer server. A blockchain organizes information added to the ledger into blocks or groups of data. Each block can only hold a certain amount of information, so new blocks are constantly being added to the ledger, forming a chain. Each block has its own unique identifier, a cryptographic “hash.”

The hash not only protects the information within the block from anyone who does not have the required code, but also protects the block’s place in the chain by identifying the block that came before it. The cryptographic hash is “a series of numbers and letters that can be up to 64 digits long,” says Vikas Agarwal, a partner in PwC’s Financial Services Advisory practice. “Once information is added to the blockchain and encrypted with a hash, it is permanent and immutable. Each node has its own record of the entire timeline of data along the blockchain, going back to its beginning.

If someone hacks into a computer and manipulates the data for their own benefit, the information stored by other nodes will not be altered. The way the system works, it’s almost impossible for someone to replicate the computing power that’s going on in the background and somehow figure out what all those hashes are

How it works. Here’s an example of how blockchain is used to verify and record bitcoin transactions. A consumer buys bitcoin. The transaction data is sent across the decentralized network of bitcoin nodes. The nodes validate the transaction. The completed block is encrypted and the transaction record is permanent; it cannot be removed or modified from the blockchain.

Bitcoin’s blockchain is public, meaning that anyone who owns Bitcoin can view the transaction record. Although it can be difficult to trace the identity of an account, the record shows which accounts are transacting on the blockchain. Public blockchains also allow any user with the necessary computing power to participate as a node in approving and recording transactions on the blockchain.

But not all blockchains are public. Blockchains can be designed as private ledgers, allowing an owner to restrict who can make changes or additions to the blockchain. With a private blockchain, the pool of participants is smaller, but still decentralized among participants. The idea of a secure, decentralized, and permanent record of information has attracted interest from numerous industries and potentially offers solutions to many security concerns, record-keeping processes, and data ownership issues we face today.

A blockchain-based future. Blockchain gives us the technology to move information securely and to recognize the authenticity of any information you want to protect with near absolute certainty. Consider, for example, the stories that have circulated in recent weeks about memes and celebrities who have monetized digital property by selling NFTs (non-fungible tokens). Because the underlying blockchain record is immutable, sellers can use NFTs to verify the authenticity of a digital asset. When you buy an NFT, that transaction is added to the blockchain ledger and becomes a verifiable proof of ownership. For those who want to verify the authenticity of a digital work, the blockchain helps value digital art and collectibles similarly to their physical counterparts. In theory, this results in creators receiving value for their works by receiving royalties for copies of digital art.
