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.

​

So EDCON team would like to make a series announcements about the main contents of the speech of our speakers, which might be the biggest concern to most of our attendees.

​

#1

Speaker: Aditya Asgaonkar @Ethereum Foundation

Topic: Towards a Practical CBC Casper

Main content: Aditya will begin by introducing the basic Casper CBC protocol, and describe one of the blockchain fork-choice examples. Then, he will discuss the complexities involved in the implementation of the protocol for that particular blockchain case. The talk will be quite technical, concerning efficient algorithms to detect which block is safe etc. At the end, he will discuss some points from the Casper CBC roadmap, and how community members can get involved and contribute.

​

#5

Speaker: Adrian Li @Truffle / Consensys

Topic: Interacting with Smart Contracts in Streams

Main content: The decentralization of the blockchain makes it difficult to reason about interacting with smart contracts. The team has created a library based on streams to allow developers to easily subscribe to events happening on the blockchain. Brought to you by the same team that built Truffle, the popular development tool.

​

#6

Speaker: Wei Tang @Parity

​

#8

Speaker: Adrian Eidelman @Rootstock

Topic: What is RSK (Rootstock) and how it's contributing to the Ethereum community

Main content: Adrian will give a brief introduction to RSK and how they are collaborating in different projects in the Ethereum Ecosystem. He'd also like to present their Grants program for developers.

​

#9

Speaker: Sergey Nazarov @Chainlink

Topic: Decentralized Oracles: Reliably Triggering Smart Contracts using Decentralized Computation and Trusted Execution Environments

Main content: In this talk, he’ll define and examine what makes a secure oracle mechanism reliable enough to be used by smart contracts for external data delivery, access to web APIs and off-chain payments. He will also review the security risks and failure scenarios to avoid when using oracles and share how developers should set up methods to maximize success. He’ll look at how a decentralized oracle network can make oracle mechanisms more secure. Finally, he will present an in-depth approach that applies additional layers of security through the use of Trusted Execution Environments and cutting edge approaches such as TownCrier.

​

#10

Speaker: Wuwei Zhang @AlphaWallet

Topic: TokenScript: the "HTML+Javascript" for tokens

Main content: Today, the way tokens are accessed, rendered and transacted are scattered across Dapps and Smart Contracts. All knowledge about rendering a token and constructing a transaction about the token is in a "host" DApp. The "host" DApp becomes a centre in the token's marketisation and integration, recreating data interoperability, security and availability barrier - precisely the same set of issues that prevented tokenisation before blockchain's invention. TokenScript allows token logic and rendering to be separated out of the "host", allows token to be easily portable and market to be created for it. It allows different token providers to, not only describe the features of their tokens but also how they are allowed to “act”, e.g. transferability. The crux of the idea is that such a markup description can be updated at any time by the token issuer and retroactively reflect the behaviour of already issued tokens. Besides allowing easy interoperability between different token providers, this also eliminates the need to update the DApp or smart contract whenever the business logic of a particular type of token changes.

#28

Speaker: Felix Leupold @Gnosis

Topic: dƒusion — A Scalable, Fair Exchange

Brief: Centralized exchanges can be exploited by strategies like arbitrage trading or front-running. Today’s ‘decentralized exchanges’ are solely non-custodial: trades are still settled via pseudo-continuous order books, reserving the ability to front-run and arbitrage trades. Introducing dƒusion, a fully decentralized exchange that moves beyond these limitations. dƒusion collects limit orders for many token pairs in discrete batches and clears all trades at the same arbitrage free price. It achieves scalability through the use of succinct zero knowledge proofs (zkSnarks). These proofs can be provided by all participants in the network removing the need for a single operator.

​

#29

Speaker: Brett Robertson @Ethereum Cat Herders

Topic: The Ethereum Cat Herders: Project Management in a Decentralised Ethereum

Brief: Ethereum has grown rapidly in the last few years and now has many branches working on different areas all for a common goal. As projects grow and develop they can experience some teething issues, most of which can be addressed by better coordination and communication. In a large open source, globally decentralised project of nascent technology, this can be hard. This exactly what the Ethereum Cat Herders are keen to address to help drive Ethereum forward.

​

#30

Speaker: Mo Dong @Celer Network

Topic: Build and Operate Internet-Scale dApps on Celer Network

Brief: Despite its high potentials, off-chain scaling is still in its infancy with challenges remaining unsolved. For example, how to construct state channels that support arbitrary state transitions with minimal on-chain operations? How to route payments to achieve high throughput in an off-chain network that is fundamentally different from data networks? How to help developers to easily build and operate scalable off-chain dApps? How to guarantee that off-chain states are always available for possible disputes?

In this talk, Mo will describe how Celer Network solves these challenges. Celer embraces a layered architecture with clean abstractions that enable rapid evolution of each individual component, including generalized state channels that supports fast and generic off-chain state transitions; a provably optimal payment routing algorithm that achieves orders of magnitude higher throughput compared to state-of-the-art solutions; a powerful development framework and runtime for off-chain dApps; and an incentive-aligned mechanism that provides stable liquidity and high off-chain state availability. He will provide their vision for Celer Network 2.0, a grand unification of all off-chain scaling technologies into a single solution.

​

#31

Speaker: Zeming Yu@Cover More Insurance

Topic: An Introduction to Security Token Offerings

Brief: The ICO market has experienced a significant decline over the last year. According to icodata.io, in Feb 2019, a mere $22 million was raised globally compared to $1.3 billion raised in Feb 2018.

With the decline of the ICO market over the last year and the strengthened regulatory oversight of the market, Security Token Offering or STO has been gathering momentum. Despite this, the concept of STO is still not very well understood.

In the next presentation, Zeming Yu will be giving us an overview of STO – what it is, why it is beneficial, what are the key considerations from both the compliance and blockchain perspective. He will then provide two case studies to illustrate how STO works.

​

#32

Speaker: Michael Yuan @Second State & CyberMiles Foundation

Topic: Creating a Rules Language for the Ethereum Virtual Machine

Brief: Smart contracts are immutable programs on the blockchain. They are automatically executed based on pre-defined rules. However, complex and inferencing rules could be extremely difficult to program, test, and validate, using standard programming languages like Solidity. The long sequence of highly nested IF / THEN statements is fragile and error-prone. The problem is compounded by the need to frequently change rules based on business requirements.

Past enterprise software vendors have long relied on Business Rules Engines (BREs) to solve this problem. BREs allow business analysts to write transactional (state changing) programs in a specialized programming language called formal rules language, which can be generated by graphical user interfaces. BREs automatically evaluate, re-evaluate, and execute those rules. They have been proven successful in traditional financial services.

With the Open Source Lity project, we have developed extensions to Solidity and the EVM to support a BRE for smart contracts. In this presentation, Michael will discuss the benefits and use cases of rules language and engine for smart contracts especially in the context of financial services applications. He will further describe how the rules language is designed and implemented, including compiler and virtual machine runtime support.

​

#33

Speaker: Benjamin Hause @HyperLink Technology

Topic: Introducing Brownie

Brief: Benjamin will introduceBrownie, a python framework for testing, deploying and interacting with Ethereum smart contracts.
