To use the Fabric samples, you need to download the Fabric Docker images and the Fabric CLI tools. First, make sure that you have installed all of the Fabric prerequisites. You can then follow the instructions to Install the Fabric Samples, Binaries, and Docker Images in the Fabric documentation. In addition to downloading the Fabric images and tool binaries, the Fabric samples will also be cloned to your local machine.
The Fabric test network in the samples repository provides a Docker Compose based test network with two Organization peers and an ordering service node. You can use it on your local machine to run the samples listed below. You can also use it to deploy and test your own Fabric chaincodes and applications. To get started, see the test network tutorial.
The Kubernetes Test Network sample builds upon the Compose network, constructing a Fabric network with peer, orderer, and CA infrastructure nodes running on Kubernetes. In addition to providing a sample Kubernetes guide, the Kube test network can be used as a platform to author and debug cloud ready Fabric Client applications on a development or CI workstation.
You can sell and buy all the products and items from our blockchain.
| Smart Contract | Description | Tutorial | Smart contract languages | Application languages |
|---|---|---|---|---|
| Basic | The Basic sample smart contract that allows you to create and transfer an asset by putting data on the ledger and retrieving it. This sample is recommended for new Fabric users. | Writing your first application | Go, JavaScript, TypeScript, Java | Go, JavaScript, TypeScript, Java |
| Ledger queries | The ledger queries sample demonstrates range queries and transaction updates using range queries (applicable for both LevelDB and CouchDB state databases), and how to deploy an index with your chaincode to support JSON queries (applicable for CouchDB state database only). | Using CouchDB | Go, JavaScript | Java, JavaScript |
| Private data | This sample demonstrates the use of private data collections, how to manage private data collections with the chaincode lifecycle, and how the private data hash can be used to verify private data on the ledger. It also demonstrates how to control asset updates and transfers using client-based ownership and access control. | Using Private Data | Go, Java | JavaScript |
| State-Based Endorsement | This sample demonstrates how to override the chaincode-level endorsement policy to set endorsement policies at the key-level (data/asset level). | Using State-based endorsement | Java, TypeScript | JavaScript |
| Secured agreement | Smart contract that uses implicit private data collections, state-based endorsement, and organization-based ownership and access control to keep data private and securely transfer an asset with the consent of both the current owner and buyer. | Secured asset transfer | Go | JavaScript |
| Events | The events sample demonstrates how smart contracts can emit events that are read by the applications interacting with the network. | README | JavaScript, Java | JavaScript |
| Attribute-based access control | Demonstrates the use of attribute and identity based access control using a simple asset transfer scenario | README | Go | None |
Additional samples demonstrate various Fabric use cases and application patterns.
| Sample | Description | Documentation |
|---|---|---|
| Commercial paper | Explore a use case and detailed application development tutorial in which two organizations use a blockchain network to trade commercial paper. | Commercial paper tutorial |
| Off chain data | Learn how to use the Peer channel-based event services to build an off-chain database for reporting and analytics. | Peer channel-based event services |
| Token ERC-20 | Smart contract demonstrating how to create and transfer fungible tokens using an account-based model. | README |
| Token UTXO | Smart contract demonstrating how to create and transfer fungible tokens using a UTXO (unspent transaction output) model. | README |
| High throughput | Learn how you can design your smart contract to avoid transaction collisions in high volume environments. | README |
| Simple Auction | Run an auction where bids are kept private until the auction is closed, after which users can reveal their bid. | README |
| Dutch Auction | Run an auction in which multiple items of the same type can be sold to more than one buyer. This example also includes the ability to add an auditor organization. | README |
| Chaincode | A set of other sample smart contracts, many of which were used in tutorials prior to the asset transfer sample series. | |
| Interest rate swaps | Deprecated in favor of state based endorsement asset transfer sample | |
| Fabcar | Deprecated in favor of basic asset transfer sample |
