Use Cases Of Blockchain Technology And Smart Contracts

ALTHOUGH the roots of blockchain technology goes back to the 1990's, the first widely  used example of it, the Bitcoin blockchain,  sparked the popularity of blockchains in  2009. In short, blockchains are decentralized digital ledgers consisting of "blocks" of  information attached to each other by way  of cryptographic hashing and are extremely difficult to tamper with. Each "block"  contains a hash value itself, as well as the  hash value of the previous "block." As the  slightest alteration in a block changes the  entire hash code of that block and, thus, the  subsequent blocks as well, miners can easily  detect an anomaly in the blockchain and  dispose of false information or transactions.
