You will need about 30GB of storage space to sync a testnet. We will only need to sync the mainnet when we are ready to deploy. When you’re developing a smart contract, you should sync the testnet first. The Ether’s value is tied to real fiat currency via cryptocurrency exchanges.Īs developers, we do not want to run application tests with real money. The mainnet is used to transact real Ether. In Ethereum, there are two main networks: the mainnet and the testnet. Mist is basically a browser that renders decentralized applications (dApps) and websites.įor the development of a smart contract, we will only need the Ethereum Wallet. It has a user-friendly interface, and I’m also a bit biased because it is developed by Ethereum itself. You can find many different wallets for Ethereum with a quick Google search (such as Parity, Jaxx, and MyEtherWallet). We call the GUI that interacts with the network the “wallet”. Refer to Geth’s instructions for more details.Ĭheck that Geth is installed properly by typing geth version in the terminal (MacOS) or PowerShell (Windows). You can do so with the following commands: brew tap ethereum/ethereumbrew install ethereum Then click on the “Geth for Windows” button.įor MacOS users, I recommend that you download using homebrew. To download Geth, go here for Windows users. Ethereum Wallet - User interface for an Ethereum node.To sync an Ethereum node, we will need the following software: Although you can deploy them manually without syncing to an Ethereum node, in the long run it’s more convenient for the development process to sync (especially when we want to use development frameworks like Truffle). In Ethereum, developers create pieces of an application that run on the network.

Hopefully, you won’t have such a nasty early experience as I did. Not knowing the terminology only made it harder.Īnd so, in this article, I want to consolidate all the common errors you might face and explain the reasons behind each step when syncing a node. It was such a headache that I almost gave up. With no one to hold my hand and nowhere to consolidate all the common errors I encountered, I wasted weeks just syncing a node. When I first started developing on the Ethereum platform, syncing a node was one of the first few things I did.
