+# `@hyperledger/cactus-plugin-bungee-hermes`
+
+The package provides `Hyperledger Cacti` a way to create blockchain snapshots and views for different distributed ledgers currently supported by Cacti. The implementation follows the paper [BUNGEE](https://dl.acm.org/doi/pdf/10.1145/3643689) (Blockchain UNifier view GEnErator).
+
+The plugin will allow, as suggested in the paper, "new applications built on top
+of dependable blockchain interoperability, such as stakeholder-centric snapshots for audits, cross-chain analysis, blockchain
+migration, and combined on-chain-off-chain analytics".

+
+
+## Getting Started
+
+Clone the git repository on your local machine. Follow these instructions that will get you a copy of the project up and running on
+your local machine for development and testing purposes.
+
+### Prerequisites
+
+In the root of the project to install the dependencies execute the command:
+```sh
+npm run configure
+```
+
+Know how to use the following plugins of the project:
+
+  - [cactus-plugin-ledger-connector-fabric](https://github.com/hyperledger/cactus/tree/main/packages/cactus-plugin-ledger-connector-fabric)
+  - [cactus-plugin-ledger-connector-besu](https://github.com/hyperledger/cactus/tree/main/packages/cactus-plugin-ledger-connector-besu)
+
+
+## Architecture
+
+The plugin interacts with a cactus ledger connector, using strategies with custom logic for each different network.
+
+Note that, so far, only strategies for Fabric and Besu networks were implemented. Smart-contracts in Fabric and Besu must implement the interface provided in the files ITraceableContract.ts and ITraceableContract.sol, in the test directory 
+
+The plugin stands _behind_ a cacti-ledger-connector, which is used to fetch information from the ledger to create the snapshot.
+```typescript
+.......................................
+.            Cacti Node               .
+.                                     .
+.                                     .
+. ..........            ............. .          .........
+. .        .            .   Cacti   . .          .       .
+. . BUNGEE . ---------- . Connector . -----------. _DLT  . 
+. .        .            ............. .          .       .
+. ..........                          .          .........  
+.                                     .
+.                                     .
+.                                     .
+.......................................
+```
+The plugin can then serve multiple purposes, and thus serve also other plugins or apps in more complex deployment architectures (where we link bungee to other components).
+
+### BUNGEE - Hermes API
+
+This plugin uses OpenAPI to generate the API paths.
+Endpoints exposed:
+
+  - CreateViewV1
+  - GetPublicKey
+  - GetAvailableStrategies
+
+
+## Running the tests
+  - **besu-test-basic.test.ts**: A test using strategy-besu and a besu connector, testing creating views for different timeframes and states.
+  - **fabric-test-basic.test.ts**: A test using strategy-fabric and a fabric connector, testing creating views for different timeframes and states.
+  - **besu-test-pruning.test.ts**: A test using strategy-besu and a besu connector, testing creating views for specific timeframes.
+  - **fabric-test-pruning.test.ts**: A test using strategy-fabric and a fabric connector, testing creating views for specific timeframes.
+  - **bungee-api-test.test.ts**: A more complex test, using both besu and fabric strategies, fabric and besu connectors, and calls to bungee-hermes API. Tests bungee's API and functionality with multiple strategies. 
+
+Tests developed using JEST testing framework.
+
+## Usage
+Lets imagine we want bungee-hermes to create views for a besu ledger.
+Let us consider a besu ledger connector, exposing its API on URL: http://localhost:4000
+
+
+Then we instantiate the plugin as follows:
+```typescript
+const pluginBungeeHermesOptions = {
+    keyPair: Secp256k1Keys.generateKeyPairsBuffer(),
+    instanceId: uuidv4(),
+    logLevel,
+};
+const bungee = new PluginBungeeHermes(pluginBungeeHermesOptions);
+```
+
+We add the desired strategies:
+
+```typescript
+bungee.addStrategy('BESU_STRATEGY', new StrategyBesu("INFO"));
+```
+
+Save network details for our target ledger:
+
+```typescript
+const besuNetworkDetails: BesuNetworkDetails = {
+    signingCredential: besuSigningCredential,
+    contractName: besuContractName,
+    connectorApiPath: 'http://localhost:4000',
+    keychainId: besuKeychainPlugin.getKeychainId(),
+    contractAddress: besuContractAddress,
+    participant: accountAddress,
+  };
+```
+
+And we can request views, after exposing the api:
+```typescript
+const expressApp = express();
+  expressApp.use(bodyParser.json({ limit: "250mb" }));
+  bungeeServer = http.createServer(expressApp);
+  const listenOptions: IListenOptions = {
+    hostname: "127.0.0.1",
+    port: 3000,
+    server: bungeeServer,
+  };
+const addressInfo = (await Servers.listen(listenOptions)) as AddressInfo;
+const { address, port } = addressInfo;
+
+await bungee.getOrCreateWebServices();
+await bungee.registerWebServices(expressApp);
+const bungeePath = `http://${address}:${port}`;
+
+const config = new Configuration({ basePath: bungeePath });
+const bungeeApi = new BungeeApi(config);
+
+const viewBesu = await bungeeApi.createViewV1({
+    strategyId: 'BESU_STRATEGY',
+    networkDetails: besuNetworkDetails,
+    tI: undefined,          //default to 0 (UNIX timestamp seconds)
+    tF: undefined,          //default to Number.MAX_SAFE_INTEGER.toString() (UNIX timestamp seconds)
+    stateIds: undefined,    //default to capture all assets
+    viewID: undefined,      //plugin generates the id, if not given
+  } as CreateViewRequest);
+```
+
+Note that each strategy can be used to query different ledgers (ledgers of the same type, but on different locations), and BUNGEE also supports adding multiple strategies to each bungee-hermes-plugin instance.
+Each strategy implements the logic to query information from each different ledger (i.e. capture set of asset states), while bungee-hermes plugin handles the snapshot and view creation.
