Smart Contracts

Now that we have the power to use technology for trust, instead of third parties — we can see when transactions were made, by a trusted source and integrate this information. Smart contracts take this one step further by automating transactions, because now we don’t need banks and other third-parties to approve things, we have secure, trustless technology to do that.

Testnets

The 2 types of testnet nodes

There are 2 types of ethereum test nodes:

  1. Heavyweight Ethereum nodes: used to connect to large-scale publicly networked testnets, like Ropsten.

You need a place to test your smart contract before it goes live / you spend actual currency

You can even play around with “fake” cryptocurrency on these platforms but there are a few steps you have to take to ensure that you don’t spend your real ether when building them. There are ways to run your contracts on the Ethereum test network with only the minute cost of gas — you can view the Ropestan chart prices here. If you’re a developer just getting into smart contracts, we’ll do a post on this for you soon. But, entrepreneurs only need to know that there are steps your developer can take to ensure that they don’t accidentally interact with the main net, when they think you’re interacting with a testnet.

In short

  • Smart contracts automate actions and run on the blockchain.
  • Developers use testnets to test and preview smart contracts before they are launched.
  • Developers can use test crypto to play around with on a testnet but need to make 100% sure that they’re using a test network and not connected to the main networks, so that they don’t accidentally spend real currency.
