Upon discovering Bitcoin’s blockchain, we now know that it stores information about monetary transactions. Blockchains are now used by more than 10,000 other cryptocurrency systems. However, blockchains work well for not only Bitcoin transactions, but also for storing data about other types of transactions.
Blockchain is already being used by companies such as Pfizer, AIG, Siemens, Unilever, and Walmart. For instance,To track products’ journey from their origin to their destination, IBM created its Food Trust blockchain.
What is the purpose of this? Using blockchain technology, brands can track food products from their origin to each stop along their journey, and finally to their final destination. In the event that contaminated food is found, its origin can be tracked back through each stop. Furthermore, since these companies now see everything else they have come into contact with, identifying the problem much faster and potentially saving lives is possible. A blockchain implementation such as this is just one example of many possible implementations apart from being used in cryptocurrency.
The Blockchain Platform
An existing blockchain infrastructure can be used in new ways by developers and users. Ether (ETH), for instance, is an Ethereum-based cryptocurrency. Ethereum supports smart contracts as well as non-fungible tokens (NFTs) that are used in initial coin offerings (ICOs). Ethereum provides an infrastructure that all of them rely on, and they are all secured by Ethereum nodes.
What Is the Current Number of Blockchains?
Every day, there are more and more live blockchains. The number of cryptocurrencies based on blockchain is expected to reach 10,000 by the end of 2022, with several hundred additional non-cryptocurrency blockchains.
Which Blockchain Is Public and Which One Is Private?
Often called a permissionless or open blockchain, a public blockchain allows anyone to join and become a node on the network. The open nature of these blockchains makes them dependent upon cryptography-based security systems and consensus mechanisms, such as proof of work (PoW).
On the other hand, in a private or permissioned blockchain, nodes must be approved before they can join. Since nodes are regarded as trusted, security layers do not need to be as extensive.
The Blockchain Invention?
Stuart Haber and W. Scott Stornetta, were the two mathematicians who wanted to use blockchain technology to prevent the interception of document timestamps, outlined blockchain technology for the first time in 1991. A cryptopunk named Nick Szabo once proposed using blockchain technology for securing a digital payments system, known as bit gold (although it was never implemented).
Where does blockchain go from here?
In part because of Bitcoin Wallet transactions and other cryptocurrencies, blockchain is finally making a name for itself by being applied to many practical applications. It’s no secret that blockchain stands to improve business and government operations by making them less costly, more efficient, and more secure.
As blockchain enters its third decade, the question is now not whether legacy companies will catch on to it, but when. NFTs and tokenization of assets are on the increase today. Blockchain is set to grow rapidly in the coming decades.
