Tokens can be classified from different perspectives.
Thus, from a technical point of view we have:
Native token of a blockchain. A token implemented in and part of the network
protocol it is issued in (eg BTC).
Non-native token. A cryptocurrency created by a project only for use within its
borders, issued on a network after the fact for a variety of purposes, like wrapped
tokens, application utility tokens, governance tokens, or stablecoins.
Application token: tokens that are native to decentralized applications and have a
cryptographic asset associated with their use or monetization, without locking value in
its parent protocol (eg SAFEcoin).
Depending on its purpose:
Cryptocurrencies, created with that specific utility to serve as crypto-currency (eg
Zcash)
Network tokens: initially intended to use within a specific system (eg GNO from the
gnosis olimpya network).
Investment tokens. A token that is primarily intended as a way to passively invest in
the issuing entity or the underlying asset (eg Digix Gold).
Based on the underlying value behind the token:
Asset-backed tokens. A representation of ownership of a physical asset. Derives its
value based on the underlying asset (eg USDT).
Tokens that give value to a network. Linked to the value and development of the
network (eg ETH).
Tokens assimilated to stock. (ex. DigixDao's DGD).
In any case, we will wait to have the final text and we will continue reporting.
If we classify them by their usefulness:
Usage tokens: that give access to a digital service, guaranteeing its holder exclusive
access to the functionality of the service (eg STX).
Work token: they give the right to contribute to a system in exchange for rewards or
utilities within a decentralized organization (eg Maker DAO).
Hybrid tokens: with working and usage token traits (eg Eth or Dash).
And according to their legal status:
Utility token: it offers its owner a clearly defined utility within a network or
application. It can function as an internal payment currency of a network or an app (eg
BAT from Brave).
Security token: token that behaves as a value. A hybrid between shares of a company
and cryptocurrency. Its owner is considered the owner, granting rights and obligations
(eg Bitwala).
Cryptocurrencies: it is the crypto-currency in the strict sense. It acts as a reserve of
value and a medium of exchange, not being issued by a central authority. Today it does
not have the consideration or functionality of a legal tender currency, so it is not
regulated under the laws that govern money (eg Btc).
