The Future is Block: A Comprehensive Guide to the Technology

This book could provide a comprehensive definition of blockchain technology how it works and the foundational concepts behind it. Blockchain should be considered a special type of database. You may have heard the term distributed ledger along with Blockchain in the specialized review of cryptocurrencies such as Bitcoin. Both refer to the same concept. Blockchain has unique characteristics and there are specific rules on how data can be added. One of the points that make this technology a great platform for the development of cryptocurrencies is the impossibility of manipulating or changing the data after it is stored. Data is added over time in a framework of blocks. Each block builds on the last one and contains information to link to the previous block. By viewing the newest and most up-to-date block we can check that it was created after the last option. By going through the blockchain and following the blocks from the end to the beginning we will reach the first item called Genesis Block.
