A token, in the Australian crypto context, refers to a digital asset built on an existing blockchain, much like an app runs on an operating system. Unlike cryptocurrencies with their own independent blockchains (like Bitcoin or Ethereum), tokens leverage the security and infrastructure of their host chain. This makes them versatile for a wide range of applications, from representing real-world assets to enabling decentralised finance (DeFi) protocols.
How it works
Most commonly, tokens are created on the Ethereum blockchain following the ERC-20 standard, although other blockchains like Binance Smart Chain (BEP-20) or Solana also host numerous tokens. The ERC-20 standard provides a common set of rules and functions that all tokens built on Ethereum must adhere to. These rules dictate how tokens can be transferred, how their supply is managed, and how they interact with smart contracts. Developers can create new tokens with specific functionalities by coding smart contracts on the host blockchain, defining the token's properties and behaviour. When you transact with a token, you are essentially interacting with these underlying smart contracts.
Because tokens share the underlying blockchain's security and network, they benefit from its decentralisation and immutability. Each transaction involving a token is recorded on the host blockchain's ledger. The process of creating and distributing tokens is often much simpler and less resource-intensive than launching an entirely new blockchain, making them a popular choice for new projects and decentralised applications (dApps).
Why it matters for Australian investors
For Australian investors, understanding tokens is crucial as they represent a significant portion of the digital asset market and offer diverse investment opportunities beyond just traditional cryptocurrencies. Many innovative projects and new technologies within the crypto space are launched as tokens. The flexibility of tokens allows for various use cases, such as utility tokens providing access to services, security tokens representing ownership in real-world assets, and governance tokens granting voting rights in decentralised autonomous organisations (DAOs). Being familiar with different token standards and their underlying blockchains enables investors to better assess the potential and risks associated with these assets. It's also important to remember that the Australian Tax Office (ATO) treats tokens, like other cryptocurrencies, as capital gains tax (CGT) events when you dispose of them, so accurate record-keeping is essential.
Common questions
Q: What's the difference between a coin and a token?
A: A "coin" (like Bitcoin or Ethereum) has its own independent blockchain and functions as the native currency of that network. A "token", conversely, is built on top of an existing blockchain and relies on that infrastructure, often serving a specific purpose within an application or ecosystem.
Q: Can tokens be bought and sold on Australian exchanges?
A: Yes, many popular tokens are listed and can be bought and sold on various Australian cryptocurrency exchanges. However, the availability of specific tokens can vary between platforms, so it's always best to check the exchange's listings.
Q: What are some common examples of tokens?
A: Popular examples include Tether (USDT) and USD Coin (USDC), which are stablecoins pegged to the US dollar, and Chainlink (LINK), which provides real-world data to smart contracts. There are also numerous tokens associated with decentralised finance (DeFi) protocols, gaming, and metaverse projects.
