Future Research Directions

Digital ledgers called “blockchains” are stored on a decentralized network. The decentralized ledger system known as blockchain records all transactions without exception and is most often used in Bitcoin financial transactions. Public, consortium, or private solutions may be provided by blockchain technology, which is immutable, transparent, trustworthy, decentralized, and autonomous. People have begun to use blockchain technology in several other areas as a result of Bitcoin’s success, including the financial market, supply chain, voting, healthcare, and IoT security. Since it was first developed for Bitcoin, blockchain technology has expanded to include a wide variety of uses outside of cryptocurrency.
