FLO (Florincoin), launched in 2013, is a mineable coin using the Scrypt algorithm with the unique feature of allowing metadata to be directly attached to the blockchain through the floData feature. This opens up many applications for decentralized data storage such as timestamping text, storing content, or identifying numbers and sharing research data. FLO has no pre-mining or ICO, is completely open source and community-operated, and has been applied in projects like Open Index Protocol, tZERO, and Caltech University.
Currently, FLO is trading around $0.07, with a market capitalization of about $600–700K, and the circulating supply ranges from approximately 9 to 152 million depending on the source. However, WikiBit has raised some warning signs about the risk of the model potentially operating like a pyramid scheme.
