$GO is the cryptographic token that powers the GoChain network. If your unfamiliar with what a token is, then we suggest you read our Get Started article ‘What is a Token’ before continuing. What is $GO used for? Why does GoChain need a token? How do I purchase GO? Purchase $GO What is $GO used for? $GO powers GoChain’s third generation public blockchain.Users, businesses, and developers use $GO to pay for network services, such as running a smart contract, storing a file, or transferring tokens. For each transaction submitted to the network, $GO are used to compensate network nodes for bandwidth, compute, and storage.$GO is identical in its use to Ethereum’s token, $ETH, which is often called the “gas” of the Ethereum blockchain. Similar to how a person must utilize gasoline or petrol to operate a vehicle, the GoChain network requires $GO tokens to operate. Why does GoChain need a token? Simply put, tokens protect networks for abuse and DDoS attacks.Blockchains, and networks in general, are scalable to a certain capacity. While GoChain has a significantly higher capacity (100x) than its peer network, Ethereum, there is always the possibility a malicious actor could potentially run a script using multiple computers to bog the network down by making 1,300 transactions of worthless information every second and deny service to everyone else.This kind of thing does happen often with traditional networks. We see it most often in the form of DDoS (distributed denial of service) attacks against websites. So how do you stop it?As we mentioned, executing transactions on the GoChain network requires the user to spend $GO tokens. So long as tokens are not free to acquire, the bad actor conducting the attack would have to invest a significant amount of capital in attacking the network to deny service to others. For every minute of they attack, this would cost nearly 100,000 $GO tokens. How do I purchase GO? $GO tokens can be purchased on a variety of exchanges and currency exchange systems. GoChain does not endorse or recommend one exchange over another. To view a list of exchanges or services navigate to our Purchasing $Go page.
