Neo

Neo is an open-source blockchain that has two native tokens: NEO and GAS. NEO is an investment and governance token, allowing tokenholders to vote on improvements to the blockchain. The GAS token is used to pay fees for transactions on the blockchain. One of the Neo co-founders authored its unique consensus algorithm, Delegated Byzantine Fault Tolerance, which deters untrustworthy users from participating in the blockchain’s operation.
