Before we begin, if you haven’t already done so, you may wish to check that you have all the Pré-requisitos installed on the platform(s) on which you’ll be developing blockchain applications and/or operating Hyperledger Fabric.
Once you have the prerequisites installed, you are ready to download and install HyperLedger Fabric. While we work on developing real installers for the Fabric binaries, we provide a script that will Instale exemplos, executáveis e imagens Docker to your system. The script also will download the Docker images to your local registry.
After you have downloaded the Fabric Samples and Docker images to your local machine, you can get started working with Fabric with the Using the Fabric test network tutorial.
Hyperledger Fabric smart contract (chaincode) APIs¶
Hyperledger Fabric offers a number of APIs to support developing smart contracts (chaincode) in various programming languages. Smart contract APIs are available for Go, Node.js, and Java:
Hyperledger Fabric application SDKs¶
Hyperledger Fabric offers a number of SDKs to support developing applications in various programming languages. SDKs are available for Node.js and Java:
In addition, there are two more application SDKs that have not yet been officially released (for Python and Go), but they are still available for downloading and testing:
Currently, Node.js and Java support the new application programming model delivered in Hyperledger Fabric v1.4. Support for Go is planned to be delivered in a later release.
Hyperledger Fabric CA¶
Hyperledger Fabric provides an optional certificate authority service that you may choose to use to generate the certificates and key material to configure and manage identity in your blockchain network. However, any CA that can generate ECDSA certificates may be used.
