Which of the following is an application area for smart contracts? Explanation: A blockchain, originally block chain, is a growing list of records, called blocks, that are linked using cryptography. Blockchain technology is most simply defined as a decentralized, distributed ledger that records the provenance of a digital asset. A blockchain system is a transaction processing system. There are several different efforts to offer domain name services via the blockchain. [15], The words block and chain were used separately in Satoshi Nakamoto's original paper, but were eventually popularized as a single word, blockchain, by 2016.[16]. Like TCP/IP (on which the internet was built), blockchain is a foundational technology that will require broad coordination. Blockchain could slash the cost of transactions and eliminate intermediaries like lawyers and bankers, and that could transform the economy. Bitcoin is the first application of blockchain technology. A. A private key is like a password that gives its owner access to their digital assets or the means to otherwise interact with the various capabilities that blockchains now support. [133], Oracle introduced a blockchain table feature in its Oracle 21c database. [1][2][3][4] Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree, where data nodes are represented by leaves). This quiz asks broad questions about what blockchain is and what it can do. "[10] Further work on a cryptographically secured chain of blocks was described in 1991 by Stuart Haber and W. Scott Stornetta. D. Dave Bayer. Valve's prior history with gambling, specifically skin gambling, was speculated to be a factor in the decision to ban blockchain games. Given - Blockchain.
