🚧 Deprecation Notice

dfuse services will be discontinued on September 25, 2024, as Pinax transitions to more advanced and efficient solutions for Antelope blockchain data sourcing. We encourage all users to migrate to Pinax's new services, including Substreams, Firehose, and comprehensive blockchain data services supporting dozens of chains like EOS, WAX, and Telos. Dfuse users can start building with a FREE Pinax Pro Plan.

EOSIO on StreamingFast

All dfuse.io services for EOSIO, running from your laptop or from a container, released as a single statically linked binary: dfuseeos.

See the general dfuse repository for other blockchain protocols implementations.

Getting started

If it's the first time you boot a nodeos node, please review https://developers.eos.io/welcome/latest/tutorials/bios-boot-sequence and make sure you get a grasp of what this blockchain node is capable.

The default settings of dfuseeos allow you to quickly bootstrap a working development chain by also managing the block producing node for you.

Requirements

Operating System

• Linux or macOS (no Windows support for now, should work through WSL2 (untested))

dfuse Instrumented nodeos (deep-mind)

• See DEPENDENCIES.md for instructions on how to get an instrumented nodeos binary.

Installing

From a pre-built release

• Download a tarball from the GitHub Releases Tab.
• Put the binary dfuseeos in your PATH.

From source

Build requirements:

• Git
• Go 1.14 or higher (installation)
• yarn 1.15 or higher (installation)

./scripts/build.sh

This will install the binary in your $GOPATH/bin folder (normally $HOME/go/bin). Make sure this folder is in your PATH env variable. If it's missing, take a look at TROUBLESHOOTING.md.

Note -- If you're getting yarn dependency warnings while running the yarn install && yarn build commands above, you can normally safely ignore those and move forward with the installation. If you're getting an error while installing and/or compiling, see TROUBLESHOOTING.md.

Creating a new local chain with dfuseeos

1. Initialize

Initialize a few configuration files in your working directory (dfuse.yaml, mindreader/config.ini, ...)

dfuseeos init

Answer y (yes) when being prompted for Do you want dfuse for EOSIO to run a producing node for you?. If you intend is to sync an existing chain, follow Syncing an existing chain with dfuseeos instead.

2. Boot

Optionally, you can also copy over a boot sequence to have dfuse bootstraps your chain with accounts + system contracts to have a chain ready for development in a matter of seconds:

wget -O bootseq.yaml https://raw.githubusercontent.com/dfuse-io/dfuse-eosio/develop/devel/standard/bootseq.yaml

When you're ready, boot your instance with:

dfuseeos start

A successful start will list the launching applications as well as the graphical interfaces with their relevant links:

Dashboard:        http://localhost:8081

Explorer & APIs:  http://localhost:8080
GraphiQL:         http://localhost:8080/graphiql

In this mode, two nodeos instances will now be running on your machine, a block producer node and a mindreader node, and the dfuse services should be ready in a couple seconds.

Syncing an existing chain with dfuseeos

If you chose to sync to an existing chain, only the mindreader node will launch. It may take a while for the initial sync depending on the size of the chain and the services may generate various error logs until it catches up (more options for quickly syncing with an existing chain will be proposed in upcoming releases).

• See the following issue about the complexity of syncing a large chain
