Most everyone knows about or at least has heard of bitcoin. However, not everyone understands the technology of bitcoin, which extends well beyond Internet-based currency. For the rock people, bitcoin is an Internet-based currency that allows for transparency with respect to each transfer of the currency. Each transaction is locked in a block, and blocks are connected to form a "blockchain." Blockchain is an open source technology that facilitates creating each block, locking each block, and connecting the resulting string of blocks.
