Cakeshop

An integrated development environment and SDK for Ethereum-like ledgers

What is it?

Cakeshop is a set of tools and APIs for working with Ethereum-like ledgers, packaged as a Java web application archive (WAR) that gets you up and running in under 60 seconds.

Included in the package is the geth, quorum, and constellation Ethereum servers, a Solidity compiler and all dependencies.

It provides tools for managing a local blockchain node, setting up clusters, exploring the state of the chain, and working with contracts.

Download

Binary packages are available for macOS, Windows, and Linux platforms on the releases page.

Quickstart

Requirements

  • Java 7+
  • Java app server (Tomcat, Jetty, etc) [Optional]

Running via Spring Boot

Note: when running in Windows, -Dgeth.node=geth must be specified as Quorum is not yet available on Windows OS

Running via App Server

  • Download WAR file
  • Put in /webapps folder of your app server
  • Add Java system property -Dspring.profiles.active=local to startup script (setenv.sh for tomcat)
  • Start app server
  • Navigate to http://localhost:8080/cakeshop/ (default port is usually 8080)

Note: when running in Windows, -Dgeth.node=geth must be specified as Quorum is not yet available on Windows OS

Running via Docker -- NEEDS UPDATE

Run via docker and access UI on http://localhost:8080/cakeshop/

docker run -p 8080:8080 jpmc/cakeshop

You'll probably want to mount a data volume:

mkdir data
docker run -p 8080:8080 -v "$PWD/data":/opt/cakeshop/data jpmc/cakeshop

Running under a specific environment

docker run -p 8080:8080 -v "$PWD/data":/opt/cakeshop/data \
    -e JAVA_OPTS="-Dspring.profiles.active=local" \
    jpmc/cakeshop

Note that DAG generation will take time and Cakeshop will not be available until it's complete. If you already have a DAG for epoch 0 in your $HOME/.ethash folder, then you can expose that to your container (or just cache it for later):

docker run -p 8080:8080 -v "$PWD/data":/opt/cakeshop/data \
    -v $HOME/.ethash:/opt/cakeshop/.ethash \
    jpmc/cakeshop

Further Reading

Further documentation can be found on the wiki and in the docs folder.
