Ethereum Beacon Chain Explorer

The explorer provides a comprehensive and easy to use interface for the upcoming Ethereum beacon chain. It makes it easy to view proposed blocks, follow attestations and monitor your staking activity.

About

The explorer is built using golang and utilizes a PostgreSQL database for storing and indexing data. In order to avoid the situation we currently have with the Ethereum chain where closed source block explorers dominate the market we decided to make our explorer open source and available for everybody.

Sepolia
Holesky

Warning: The explorer is still under heavy active development. More or less everything might change without prior notice and we cannot guarantee any backwards compatibility for now. Once the Ethereum ecosystem matures we will be able to provide stronger guarantees about the updatability of the explorer.

Features

ToDo

  • Add chain statistic charts
  • Improve design, move away from stock bootstrap 4
  • Use a proper open source charting library
  • Come up with a smarter exporter logic (the current logic is stupid as it simply dumps the contents of the RPC calls into the database without doing any pre-aggregation or cleanups)

Getting started

We currently do not provide any pre-built binaries of the explorer. Docker images are available at https://hub.docker.com/repository/docker/gobitfly/eth2-beaconchain-explorer.

  • Download the latest version of the Prysm beacon chain client and start it with the --archive flag set
  • Wait till the client finishes the initial sync
  • Setup a PostgreSQL DB and import the tables.sql file from the root of this repository
  • Install go version 1.13 or higher
  • Clone the repository and run make all to build the indexer and front-end binaries
  • Copy the config-example.yml file and adapt it to your environment
  • Start the explorer binary and pass the path to the config file as argument
  • To build bootstrap run npm run --prefix ./bootstrap dist-css in project folder.

Developing locally with docker

  • Clone the repository

  • Run docker-compose up to start instances of the following containers eth1, prysm, postgres and golang.

  • Open a new terminal in project directory and run docker run -it --rm --net=host -v $(pwd):/src postgres psql -f /src/tables.sql -d db -h 0.0.0.0 -U postgres to create new tables in the database

  • Wait for the client to finish initial sync, you can check this by looking at logs of prysm instance.

  • Copy the config-example.yml file and adapt it to your environment.
    In your .yml file specify eth1Endpoint as './private/eth1_node/.ethereum/goerli/geth.ipc'. For database information check postgres section in docker-compose.yml file.

  • Connect to golang instance by running docker exec -ti golang bash and run make all

  • Start the explorer binary and pass the path to the config file as argument

    ./bin/explorer --config your_config.yml

Development

Install golint. (see https://github.com/golang/lint)

Commercial usage

The explorer uses Highsoft charts which are not free for commercial and governmental use. If you plan to use the explorer for commercial purposes you currently need to purchase an appropriate HighSoft license. We are planning to switch out the Highsoft chart library with a less restrictive charting library (suggestions are welcome).
