||
| ## Description | ||
|
|
||
| Rsk blockchain explorer | ||
|
|
||
| ## Components | ||
|
|
||
| ### API server | ||
|
|
||
| HTTP/WS server, see the documentation [here](doc/api.md). | ||
|
|
||
| ### Blocks services | ||
|
|
||
| Imports blockchain data from rsk node to DB. | ||
|
|
||
| - **blocksRouter:** routes messages between services *REQUIRED* | ||
| - **blocksListener:** listens to new blocks from node and announces them as service event. | ||
| - **blocksRequester:** requests blocks from node. | ||
| - **blocksChecker:** checks database for missing blocks and reorgs, emits missing/bad blocks. | ||
| - **txPool:** listens to node transactions pool and stores changes in the DB. | ||
| - **blocksBalances:** gets historical addresses balances and stores in the DB. | ||
| - **blocksStatus:** checks DB and node status and stores changes in the DB. | ||
| - **blocksStats:** gets BC stats and stores in the DB. | ||
|
|
||
| ### API user events service | ||
|
|
||
| Allows to update fields on the fly and send async response to clients. | ||
| Required by the contract verification module. | ||
|
|
||
| ## Requisites | ||
|
|
||
| - mongodb > 4 | ||
| - node >= 12.18.2 | ||
| - access to JSON/RPC interface of a rskj node >= 2.0.1 | ||
| with this modules enabled: eth, net, web3, txpool, debug and trace. | ||
|
|
||
| ## Install | ||
|
|
||
| - Install dependencies | ||
|
|
||
| ``` shell | ||
| npm install | ||
| ``` | ||
|
|
||
| ## Create log dir | ||
|
|
||
| ```shell | ||
| sudo mkdir /var/log/rsk-explorer | ||
| sudo chown $USER /var/log/rsk-explorer/ | ||
| chmod 755 /var/log/rsk-explorer | ||
| ``` | ||
|
|
||
| Note: You can change the log folder in config.json | ||
|
|
||
| ## Configuration file | ||
|
|
||
| (optional) | ||
|
|
||
| ``` shell | ||
| cp config-example.json config.json | ||
| ``` | ||
|
|
||
| see [configuration](#configuration) | ||
|
|
||
| ## Start | ||
|
|
||
| ### Services | ||
|
|
||
| Services can be started manually one by one, but we recommend to use [PM2](https://github.com/Unitech/pm2). | ||
| This repo includes a pm2 ecosystem file that starts all services automatically. | ||
|
|
||
| #### Install PM2 | ||
|
|
||
| ``` shell | ||
| npm install -g pm2 | ||
| ``` | ||
|
|
||
| To enable pm2 log rotation | ||
|
|
||
| ``` shell | ||
| pm2 install pm2-logrotate | ||
| ``` | ||
|
|
||
| see [pm2-logrotate](https://pm2.keymetrics.io/docs/usage/log-management/#pm2-logrotate-module) | ||
| see [pm2-logrotate configuration](https://github.com/keymetrics/pm2-logrotate#configure) to set the rotation options | ||
|
|
||
| e.g: | ||
|
|
||
| ```shell | ||
|
|
||
| pm2 set pm2-logrotate:compress true | ||
|
|
||
| ``` | ||
|
|
||
| #### Start services | ||
|
|
||
| ```shell | ||
| pm2 start dist/services/blocks.config.js | ||
| ``` | ||
|
|
||
| ### API | ||
|
|
||
| ``` shell | ||
| pm2 start dist/api/api.config.js | ||
| ``` | ||
|
|
||
| ## Show PM2 logs in pretty format | ||
|
|
||
| All tasks | ||
|
|
||
| ```shell | ||
|
|
||
| :~/rsk-explorer-api$ pm2 log --raw | npx bunyan | ||
|
|
||
| ``` | ||
|
|
||
| One task | ||
|
|
||
| ```shell | ||
|
|
||
| :~/rsk-explorer-api$ pm2 log blocksListener --raw | npx bunyan | ||
|
|
||
| ``` | ||
|
|
||

|
||
| ## Configuration | ||
|
|
||
| **config.json** | ||
| See defaults on: **lib/defaultConfig** | ||
| *(config.json overrides this values)* | ||
|
|
||
| Use: | ||
|
|
||
| ```shell | ||
| node dist/tools/showConfig.js | ||
| ``` | ||
|
|
||
| to check current configuration | ||
|
|
||
| **Configuration Example:** | ||
|
|
||
| ``` javascript | ||
| "source": { | ||
| "node": "localhost", | ||
| "port": 4444 | ||
| ```javascript | ||
| { | ||
| source: { | ||
| protocol: 'http', | ||
| node: 'localhost', | ||
| port: 4444, | ||
| url: null | ||
| }, | ||
| sourceRoutes: { // Nod3Router routes, used as default when source is an array of sources | ||
| subscribe: 0, // delegates subscriptions to the first node | ||
| rsk: 0, // delegates rsk module to the node that handle subscriptions | ||
| trace: 1 // delegates trace_ module to the second node | ||
| }, | ||
| "api": { | ||
| "address": "localhost", | ||
| "port": 3003 | ||
| db: { | ||
| protocol: 'postgres://', | ||
| databaseName: 'explorer_db', | ||
| host: 'localhost', | ||
| port: 5432, | ||
| user: 'postgres', | ||
| password: 12345678 | ||
| }, | ||
| "db": { | ||
| "server": "localhost", | ||
| "port": 27017, | ||
| "database": "blockDB" | ||
| } | ||
| api: { | ||
| address: 'localhost', | ||
| port: 3003, | ||
| lastBlocks: 30, | ||
| MIN_LIMIT: 10, | ||
| LIMIT: 50, | ||
| MAX_LIMIT: 500, | ||
| MAX_PAGES: 10, | ||
| allowUserEvents: false, | ||
| exposeDoc: false, | ||
| // All modules are enabled as default | ||
| modules: setAllModules(true), | ||
| delayedFields, | ||
| allowCountQueries: false | ||
| }, | ||
| blocks: { | ||
| blocksQueueSize: 10, | ||
| bcTipSize: 120, | ||
| batchRequestSize: 20, | ||
| debug: false, | ||
| ports: [3010], // list of services ports, if the list runs out, the services will try to take the next ports starting from the last | ||
| address: '127.0.0.1', | ||
| services | ||
| }, | ||
| forceSaveBcStats: true, | ||
| enableTxPoolFromApi: true | ||
| } | ||
| ``` | ||
|
|
||
| ``` | ||
| ### api | ||
| - **address** [string] api server bind address | ||
| - **port** [number] api server port | ||
| - **exposeDoc** [boolean]: serve rsk-openapi-ui on /doc to render swagger.json | ||
| - **allowUserEvents** [boolean]: allow contractVerifier | ||
|
|
||
| ### To enable contract verifier module: | ||
|
|
||
| The contractVerifier module requires a connection to a [rsk-contract-verifier](https://github.com/rsksmart/rsk-contract-verifier) | ||
| instance. The url must be provided on api section: | ||
|
|
||
| - set api.allowUserEvents to true | ||
| - add the contract verifier url inside api: | ||
| ```javascript | ||
| "api":{ | ||
| "contractVerifier": { | ||
| "url": "ws://localhost:3008" | ||
| } | ||
| api:{ | ||
| //... other configs, | ||
| contractVerifier: { | ||
| url: 'ws://localhost:3008' | ||
| }, | ||
| //... other configs | ||
| } | ||
|
|
||
| ``` | ||
|
|
||
| ### Source | ||
|
|
||
| Address of rskj node or array of addresses of rskj nodes | ||
| ## Section 3: Build process | ||
| Run commands: | ||
| - npm install | ||
| - npm run build | ||
| - npx prisma generate | ||
|
|
||
| e.g.: | ||
|
|
||
| ```json | ||
| { | ||
| "url":"http://localhost:4444" | ||
| } | ||
| ## Start | ||
| - Start block service: npm run start-blocks | ||
| - Start api: npm run start-api | ||
|
|
||
| ``` | ||
| Note: an rsk node must be running in port or url specified in defaultConfig.js. Otherwise, blocks service will crash. | ||
|
|
||
| e.g: | ||
| ## Section 4: Logs | ||
| To see block service logs: | ||
| - npm run blocks-logs-raw (production) | ||
| - npm run blocks-logs-pretty (development) | ||
|
|
||
| ```json | ||
| [ | ||
| { "url":"http://localhost:4444" }, | ||
| { "url":"http://othernode:4444" } | ||
| ] | ||
| To see api logs: | ||
| - npm run api-logs-raw (production) | ||
| - npm run api-logs-pretty (development) | ||
|
|
||
| ``` | ||
| ## Section 5: Tools | ||
|
|
||
| ### db | ||
| Get a block: | ||
| - node dist/tools/getBlock.js 4000 (print in console) | ||
| - node dist/tools/getBlock.js 4000 --save (print in console and also store in database) | ||
|
|
||
| - **server**": "localhost" | ||
| - **port**": 27017 | ||
| - **database**: "explorerDB" | ||
| Get missing segments in database: | ||
| - node dist/tools/missingSegments.js | ||
|
|
||
| **Optionals:** | ||
| ## Components | ||
|
|
||
| - **user**: < user > | ||
| - **password**: < password > | ||
| The logic in charge of indexing the blockchain in the database and maintaining data integrity consists of 4 services: | ||
| - [blocks-checker-service]: ensures integrity of the most recent 120 blocks in database at the moment of running the service | ||
| - [savetip-service]: requests blocks inside the tip size threshold (the top 120 newest, starting from latest block) | ||
| - [live-syncer-service]: requests new blocks to the RSK node, starting from latest block | ||
| - [static-syncer-service]: Stores immutable blocks (starting from latest - 120). To do so, it checks database gaps between already indexed blocks, and requests the missing ones by iterating the gaps | ||
|
|
||
| ### blocks | ||
|
|
||
| - **validateCollections** :[Boolean] Validate collections at blocks service start, default false | ||
| - **blocksQueueSize**:[Number] blocksRequester queue size | ||
| - **bcTipSize**:[Number] Number of confirmations required to check blocks | ||
| - **debug**:[Boolean] Enable logging of nod3 requests, default false | ||
| - **services**:[Object] {ServiceName:[Boolean]}. All services are enabled as default, to disable a service use: **serviceName:false** | ||
