This invention at the heart of bitcoin has ushered a wave of innovation in currencies, financial services, economics, distributed systems, voting systems, corporate governance, and contracts. In this chapter we'll examine the many offshoots of the bitcoin and blockchain inventions: the alternative chains, currencies, and applications built since the introduction of this technology in 2009. Mostly, we will look at _alt-coins_, which are digital currencies implemented using the same design pattern as bitcoin, but with a completely separate blockchain and network.
