#59

Speaker: Washington Sanchez @OpenBazaar & OB1

Topic: Integrating Ethereum into OpenBazaar

Brief: OpenBazaar is a p2p decentralised marketplace for goods and services that supports multiple cryptocurrencies for escrow-protected payment. In this presentation, we describe: 1) the integration of Ethereum and ERC-20 tokens as a new payment option, and 2) the development of an escrow smart contract that is compatible with the dispute resolution framework of OpenBazaar. The ability to pay for real-world goods and services with Ethereum and ERC-20 tokens, especially stablecoin tokens (e.g. DAI), on a global decentralised marketplace, radically extends their economic utility while providing consumers with a secure and price-stable payment solution.

Special thanks to Roberto Saltini in PegaSys for delivering such a good topic about IBFT 2.0 in the coming EDCON 2019.

1. What is IBFT?

Many of us may not be strangers to BFT algorithms, especially for SBFT of Hyperledger Fabric or Tendermint. Actually, most BFT-style consensus algorithms are all inspired by the PBFT published by Miguel Castro and Barbara Liskov (and of course, Leslie Lamport for Byzantine General Problem and his Paxos-like consensus algorithms) in 1999.

IBFT (Istanbul Byzantine-fault-Tolerance) is no exception , which is a consensus protocol developed by AMIS Technologies in 2017. It is created to provide a standard Ethereum blockchain with BFT proof-of-authority (POA) with immediate finality, especially for either private or consortium blockchains.

2. How does IBFT work?

IBFT inherits from the original PBFT by using 3-phase consensus, PRE-PREPARE, PREPARE, and COMMIT ( if you are not familiar with PBFT, review the Castro-Liskov paper through ). For simplicity, the significant comparison between PBFT and IBFT is given blow:

Before each round, a proposer will be picked out of the validator pool (say, in a round robin fashion). Then the proposer will propose a new block proposal and broadcast it along with a PRE-PREPARE message. Upon receiving the PRE-PREPARE message from the proposer, validators enter the state of PRE-PREPARED and then broadcast PREPARE message. This step is to make sure that all validators are working on the same sequence and the same round. After that, the validator who has received 2F + 1 of PREPARE messages enters the state of PREPARED and then broadcasts COMMIT message. This step is to inform its peers that it accepts the proposed block and is going to insert the block to the chain. Lastly, validators wait for 2F + 1 of COMMIT messages to enter COMMITTED state and then insert the block to the chain. The whole process looks like:

3. What is IBFT's feature?

Blocks generated in IBFT protocol are final, which means that there are no forks and any valid block must be somewhere in the main chain. To prevent a faulty node from generating a totally different chain from the main chain, each validator appends 2F + 1 received COMMIT signatures to extraData field in the header before inserting it into the chain. Thus blocks are self-verifiable and light client can be supported as well.

4. Where can I find more details?

If you want to find more details about how it works or its implementations, just visit their github by:

Also, there is an analysis paper on IBFT by Robert Saltini:

There are still many improvements for IBFT needed to be done. All of those features will be seen in IBFT 2.0. So, don't miss EDCON 2019.

What attending events in the crypto space means to most of us is that, it is a perfect chance to get the most up-to-date info. about leading and emerging projects, be it their technology progress or their business and community development roadmaps.

#39

Speaker: Lisa Chu @HTC Exodus

Topic: Rebuilding Trust and Security with Zion

Brief: EXODUS 1 is the first native web 3.0 blockchain phone with Zion Vault protecting your keys. Join us to find out how you can rebuild trust and security with us!

#40

Speaker: Roberto Saltini @PegaSys

Topic: IBFT 2.0: a robust PoA BFT consensus protocol for Ethereum

Brief: In this session Roberto will present IBFT 2.0 which is a Proof-of-Authority Byzantine-fault-tolerant consensus protocol for Ethereum that ensures immediate finality, is robust in an eventually synchronous network model and features a dynamic validator set.

He will discuss the journey and motivations behind IBFT 2.0 together with its properties, use cases and a couple of very interesting performance improvements that we are planning to implement in a future version of the protocol.

#41

Speaker: Gregory Markou @ChainSafe Systems

Topic: How Open Source Collaboration is Building ETH2.0

Brief: The importance of collaboration and communication amongst different projects in Ethereum, and other networks, while building ETH2.0

#42

Speaker: James Waugh @Axia Labs

Topic: Token Restructuring - Liquid Token Design, Governance & Incentives vs Trade-offs

Brief: Token design has shifted vastly since the first tokens launched on top of Etheruem (Maker, Augur, Digix) into fluffy payment tokens that provide very little true utility - Looking into the future a number of these projects are deploying different methods to change, remove and rebuild these tokens into new and more equitable models.

#43

Speaker: Shashank Tiwari @Cryptin & Gluon-Plasma

Topic: Scalable Account Based Systems on Ethereum

Brief: Plasma is soon becoming the most viable way to scale decentralized applications on the Ethereum network. Gluon-plasma () is an open protocol that builds on the fundamentals of Plasma and extends it to provide additional capabilities for scalable and elastic systems. Provably secure and non-custodial in nature, it aims to realize the dream of a high speed decentralized future.

#44

Speaker: Tomasz Kolinko @Eveem.org

Topic: All the things we can do with decompiled smart contracts

Brief: A well decompiled contract can be as readable, if not more, as the original source code. Not just for humans, but for machines as well. This in turn allows for all kinds of interesting tools to be built on top of it. The talk will be a brief overview of these possible use cases, and of some things that we learned already by analysing smart contracts at scale.

#45

Speaker: Liam Horne @L4

Topic: Counterfactual: State Channels Made Simple

Brief: Building state channel applications has historically been complicated. Counterfactual has taken the best research and translated it into an easy-to-use developer framework to help developers make decentralized applications that benefit from zero-fees and instant response times easy. Liam will explain how state channels work briefly and then show the framework.

#46

Speaker: Kain Warwick @Synthetix

Topic: Rethinking Finance for a Decentralized World

Brief: The first wave of decentralised platforms built on Ethereum usually tried to replicate the functionality of centralised systems directly often with poor trade-offs. We are now seeing solutions that take advantage of decentralisation. Just as we had to evolve solutions to legacy problems for the web and for mobile, we need to rethink how to solve legacy finance problems that leverage the unique properties of decentralisation. Looking at solutions like Uniswap vs Order book based DEX's may provide a path forward.

#47

Speaker: Zak Cole @Whiteblock

Topic: ETH2.0 networking

Brief: Zak will be running a demo of the Lodestar and Artemis ETH2.0 clients communicating within a functional network using the Hobbits wire protocol that we developed for 2.0 testing purposes. He will also present the Bacon Vision beacon chain visualizer. These projects were developed in collaboration with the Artemis team (ConsenSys), Lodestar team (ChainSafe) and yeeth team (Dean Eigenmann).

#48

Speaker: Matthew Slipper@Kyokan

Topic: Building Production L2 Systems

Brief: There are lots of L2 protocols, but fewer production L2 systems. Through our work with SpankChain and our grant-funded Plasma MVP implementation, Kyokan has launched L2 systems on mainnet that transfer real value. This talk focuses on what we’ve learned along the way, and presents a set of best practices and patterns to make building production L2 systems safer and easier.
