DigiByte (DGB) is an open-source cryptocurrency running on the DigiByte Blockchain, a decentralised international blockchain created in 2013. The DigiByte coin was developed in 2013 and released in January 2014. Although based on Bitcoin, adjustments in the code allow for improved functionality, including 15-second block time and improved security. As of December 2017 DigiByte has a total market cap of over US $135 million. It is the longest public blockchain in existence.
DigiByte was created by programmer and entrepreneur Jared Tate with the goal of creating a fast and secure cryptocurrency that could reach a wider and more decentralised community than Bitcoin. The first Digibyte block was mined on January 10, 2014, and included the headline from USA Today: “Target: Data stolen from up to 110M customers," hashed into the Genesis block to mark the importance of security in digital transactions. Also included was a premine to pay developers and early adopters. DigiByte pioneered asymmetrical difficulty adjustment mining with DigiShield, which is a widely used technology and the basis of many other blockchains. It is also the first to blockchain to fork from a single proof-of-work algorithm to multi-algorithm mining, however not the first cryptocurrency to use multi-algorithm (Huntercoin).
Digibyte faucets are a reward system, in the form of a website or app, that dispenses free digibyte in the form of a satoshi, which is a hundredth of a millionth DGB, for visitors to claim in exchange for completing a captcha or task as described by the website. There are also faucets that dispense alternative cryptocurrencies. Rewards are dispensed at various predetermined intervals of time. Digibyte faucets usually give fractions of a digibyte, but the amount will typically fluctuate according to the value of digibyte.
Free digibyte faucet is a great way to help introduce new people to digibyte, or to your favourite altcoin. Many faucets provide information to newbies as well as offering them some free coins so that they can try before they buy, experimenting with a test transaction or two before putting real money on the line. Since this whole area is so new and a bit scary to some people, who perhaps don't quite trust it with their hard earned cash yet, this is a great way to promote digital currency and bring in new users.
