$ARK
ARK is the token of the ARK Public Network, a blockchain platform (launched 2017) that lets developers create and deploy their own custom blockchains, with a delegated proof-of-stake consensus. It's a legacy, mid-small-cap project — far off its all-time highs from the 2018 bull run. Not to be confused with Cathie Wood's ARK Invest, which isn't a crypto token itself.
