  • Go Ethereum (1.8+)
  • Parity 1.8.11+

Installation

go get github.com/vulcanize/vulcanizedb

Setting up the Database

1. Install Postgres

2. Create a superuser for yourself and make sure psql --list works without prompting for a password.

3. createdb vulcanize_public

4. cd $GOPATH/src/github.com/vulcanize/vulcanizedb

5. Run the migrations: make migrate HOST_NAME=localhost NAME=vulcanize_public PORT=5432

   • See below for configuring additional environments

Configuration

• To use a local Ethereum node, copy environments/public.toml.example to environments/public.toml and update the ipcPath to the local node's IPC filepath:

  • when using geth:

    • The IPC file is called geth.ipc.
    • The geth IPC file path is printed to the console when you start geth.
    • The default location is:
      • Mac: $HOME/Library/Ethereum
      • Linux: $HOME/.ethereum

  • when using parity:

    • The IPC file is called jsonrpc.ipc.
    • The default location is:
      • Mac: $HOME/Library/Application\ Support/io.parity.ethereum/
      • Linux: $HOME/.local/share/io.parity.ethereum/

• See environments/infura.toml to configure commands to run against infura, if a local node is unavailable

Start syncing with postgres

Syncs VulcanizeDB with the configured Ethereum node.

1. Start node (if fast syncing wait for initial sync to finish)
2. In a separate terminal start vulcanize_db
   • vulcanizedb sync --config <config.toml> --starting-block-number <block-number>
