Polkadot (DOT): the network behind 2.1 billion tokens and its parachains

Polkadot is a network that brings many independent blockchains together under a shared security umbrella. Polkadot is therefore neither an application platform like Ethereum nor a payment network like bitcoin, but an infrastructure layer that provides other blockchains with computing time and security. The network's token is called DOT. For you as an investor, three things matter most: what the token is actually used for, how many DOT can ultimately exist and what you get if you lock them up in the network. This profile answers these questions one by one and gives the source for every figure.
