BlockForm - Ethereum Blockchain As A Service

BlockForm helps you deploy Ethereum nodes to the cloud and manage them. It takes care of creating a virtual machine in one of the supported cloud providers (currently Azure, AWS, GCP and DigitalOcean) and will install geth in the best possible way.

Blockform is a free software. It is tailored for teams or individuals whose work depends on a fleet of Ethereum nodes. You have to install your own instance. So the installation process has been made as simple as possible.

Features

• Support public networks: Mainnet, Rinkeby, Ropsten
• Allows you to create your own private ethereum network with Proof of Authority
• Support multiple cloud providers: AWS, GCP and DigitalOcean
• Support multiple synchronization modes: Full, Fast and Light
• Setup a firewall for you
• SSL certificates through certbot
• HTTP and WebSocket RPC endpoints protected by an API key
• Basic faucet web service for your private network
• Node data is saved to an SSD for faster sync
• Basic heathchecks and logs display
• Basic authentication for the UI
• Tiny chain explorer to browse your blocks, transactions and accounts
• Compatible with MetaMask, geth attach, and web3.js
• Easy deployments on Heroku
• Optional Slack integration for alerts

Note: Azure is broken and removed after the update to go 1.17 commit - this also help resolve the security issue with azure's dep github.com/dgrijalva/jwt-go

Usage

For Azure, generate a service principal:

az login
az ad sp create-for-rbac --sdk-auth

For AWS, go to IAM Management console, and generate an Access Key for your user in the Security Cretendials tab.

For DigitalOcean, go to API and generate a Personal access token.

For Google Cloud Platform:

• Create a project, for example my-blockform. If the name is not long enough, google will append some random string that you will need to export in the next steps.
• In API and Services, enable the Compute Engine API for this project.
• In API and Services, go to the Credentials tab and generate an Account Service Key as a JSON file for the Compute Engine default service account.

Set environment variables in .env:
