What we're about

The Hyperledger Foundation is an open source collaborative effort hosted by the Linux Foundation and created to advance cross-industry blockchain technologies. Participation is open to all.

Hyperledger Meetup groups have an informal relationship with Hyperledger, and make up a key part of the Hyperledger ecosystem. Participation in a Hyperledger Meetup group is open to anyone--employees of a Hyperledger member company, Hyperledger contributors and developers, and people just passionate about blockchain technology.

Link visible for attendees

Antoine Toulme, Senior Engineering Manager at Splunk and a Hyperledger Besu maintainer, leads this technical workshop about how to operate and extend the Hyperledger Besu Ethereum client.

Spaces are limited so we ask that you register in advance to make sure you have a spot in the workshop.

This workshop will contain two separate sessions -- one for operators and one for developers. You are welcome to stay for the whole event or just dial-in and stay for the content you're interested in.

Operation session (8AM to 10AM Pacific)

  • 30 minutes intro to Besu - what it does, how it works
  • 30 minutes on Besu configuration - environment variables, toml file, cli flags, hidden flags. Docker vs binary installation.
  • 60 minutes on running a Besu network
  • 15 minutes on Besu in dev mode, curl, easy first steps.
  • 15 minutes on Genesis block generation
  • 30 minutes on consortium creation, with monitoring and health report, with a Docker compose.

Developer session (10AM to Noon Pacific)

  • 20 minutes on Besu and Github - source (3 repos), issues, PRs, code checkout, CI.
  • 20 minutes on setting up with an IDE. Run and compile with Gradle. Checks and validations in place with spotless and errorprone.
  • 20 minutes on the main repository content, describing types of tests in place, showing the tree of dependencies between Gradle modules.
  • 30 minutes on adding an opcode to the EVM: show how to add a new opcode, add to the next hard fork revision, how to test it.
  • 30 minutes on how to add a new JSON-RPC method, add tests and docs.

A conceptual introduction to Decentralized Finance

Network event

Link visible for attendees

Decentralized finance is getting to be a hot topic not only with public crypto fans but it is gaining interest in classical banking and finance industry as well.

During this presentation we are trying to give a conceptual overview of DEFI (Decentralized Finance), focusing rather on DEFI concepts and algorithms instead of exact products or market mechanism.

Among the others the following topics will be discussed:
- The DEFI stack (settlement, asset, protocol, presentation, aggregation)
- Tokenization
- Exchanges, Decentralized exchanges
- Stable cryptocurrencies
- ...
