Repository checked out correctly, you can build the generator with: You have a valid Go development environment set up and the go-ethereum That can convert Ethereum ABI definitions into easy to use, type-safe Go packages. To avoid all this mess, the go-ethereum implementation introduces a source code generator RPC calls and back is extremely time consuming and also extremely brittle: implementationīugs can only be detected during runtime and it’s almost impossible to evolve a contractĪs even a tiny change in Solidity can be painful to port over to Go. However, writing the boilerplate code that translates decent Go language constructs into Interacting with a contract on the Ethereum blockchain from Go (or any other language forĪ matter of fact) is already possible via the RPC interfaces exposed by Ethereum clients. Go stale if the linked website changes, the Solidity source code of the Token contract isĪlso available at token.sol. In short the contract implementsĪ custom token that can be deployed on top of Ethereum. Probably be enough, the details aren’t relevant for now. If you’re unfamiliar with the contract, skimming the linked page should Official Token contract as the base for introducing the Go To avoid falling into the fallacy of useless academic examples, we’re going to take the Is familiar with Ethereum in general, has a fair understanding of Solidity and can code Gradually as a developer would need/encounter them. People to start out with writing Go native Dapps. This page is written in a more beginner friendly tutorial style to make it easier for This page introduces the concept of server side native Dapps: Go language bindings to anyĮthereum contract that is compile time type safe, highly performant and best of all, canīe generated fully automatically from a contract ABI and optionally the EVM bytecode. Usually not the language of choice given its dynamic nature.
It eludes the server side (backend, fully automated, devops) use cases where JavaScript is The direction of the Mist browser, through which users can interact with the blockchain.Īlthough this was a solid plan for mainstream adoption and does cover quite a lot of useĬases that people come up with (mostly where people manually interact with the blockchain), Would provide an RPC interface for JavaScript DApps to communicate with, pushing towards Performing client implementation of the consensus protocol in various languages, which The original roadmap and/or dream of the Ethereum platform was to provide a solid, high Looking for more resources?
