Highlighting Our Successful Chainlink HackerNode Event at Web3 Summit

As part of the Web3 Summit in Berlin, Chainlink hosted its own series of events focused around the ongoing development of the Chainlink ecosystem. The event featured nineteen speeches, three panel discussions, a developer workshop and multiple featured demos.

While there was a plethora of information shared, some of the key takeaways include:

  • There is an increasing amount of different datasets regarding on-chain metrics from various blockchains, especially Ethereum, available for smart contract consumption.
  • The Chainlink ecosystem is rapidly onboarding new data providers, platforms, and developer tools from around the world with different focuses.
  • The DLT ecosystem is priming for the next leap forward into new use cases, particularly enterprises, and obtaining off-chain data is a prime catalyst to enable that evolution.
  • DeFi projects are one of the fastest-growing use cases in the space, but the decentralization of price feeds via oracles is crucial to realizing its potential.

Please Note: We do apologize in advance as a few videos are a little hard to hear due to the background events (headphones will help in such instances) and the presentations of Nexus MutualCertus.one, and Ampleforth were not recorded due to technical difficulties.

Panel Discussions

Being a Chainlink Node Operator

Four current Chainlink node providers — Jonny Huxtable (LinkPool), Cristian Lucera (Bitfish), Hendrik Hofstadt (Certus.one), and Peter Eulberg (Eth.events), give their thoughts on a variety of topics such as node competition, exciting use cases, upcoming developer tools, potential roadblocks, trusted execution environments and more.

Providing Real-World Data to Blockchain

Another four independent node providers — Henri Pihkala (Streamr), Trevor Clarke (AmberData), Robert Edström (Kaiko), and Andrew Thurman (CLC Group), discuss the complexities of providing real-world data to the blockchains, particularly regulatory hurdles, pricing models, network statistics, catering to non-blockchain developers, and other audience questions.

Getting More Developers to Build on Blockchain

Four different platforms using Chainlink to obtain off-chain data — Cooper Kunz (Hedera), Oliver Birch (Wanchain), Qi Zhou (Quarkchain), and Jim Zhang (Kaleido), open up about how to attract more blockchain developers to their platforms, the introduction of the WASM programming language, Libra’s impact on blockchain adoption, how oracles impact development, and what use cases might be around the corner.


LinkPool Staking & Market

Jonny Huxtable – Co-founder & Technical Lead at LinkPool, talks in-depth about the many features being offered by LinkPool: Node-as-a-Service, Third-party staking, the Chainlink Marketplace, Consulted/Managed Nodes, and their future roadmap. He finished off by announcing that they are hiring, so please reach out to them if interested!

Synthetic Assets

Kain Warwick – Founder of Synthetix, discusses how the Synthetix platform allows users to take collateralized debt positions on a multitude of assets in diverse markets. Synthetix is part of the growing DeFi movement and has already announced its usage of Chainlink oracles for decentralized price feeds of its synthetic assets.

Create and Deploy a Token Price Oracle in 15 Minutes

Robert Edström – Head of Tech & Innovation at Kaiko, runs a demo showcasing how to quickly create a token price oracle using Chainlink, as well as digging deeper into what actually goes into constructing prices and how it affects DeFi applications.

Interplay Between Smart & Ricardian Contracts

Aaron Wright – CEO of OpenLaw, introduces the tools available by OpenLaw that transform smart contracts into Ricardian Contracts – agreements that are both legally binding and compatible with natural legal language. Ricardian Contracts are important for enabling smart contracts that operate legally in the real-world and require Chainlink oracles to connect with external resources.

The Ethereum of Tomorrow, Today.

Dennison Bertram – Developer Advocate from OpenZeppelin, outlines the developer tools available today through OpenZeppelin that make creating smart contracts substantially easier. He also reviews some of the technical code that facilitates simpler development.

Building Ethereum Workflows with Streamr

Martin Moravek – Solutions Architect and Jonathan Wolff – Software Engineer at Streamr, examines the coming IoT revolution and demos how real-time streams of data can be monetized and sold to smart contracts via the Streamr marketplace.

Decentralized Exchanges, the new Financial Market Utilities

Matthew Finestone – Head of Business Development at Loopring, analyzes the similarities between current financial market utilities and emerging decentralized protocols aiming to uproot them. He then expands on the progression of decentralized exchanges and how Loopring is solving that problem through a high output order book-based DEX.

Develop Blockchain Solutions Faster and Smarter

Jim Zhang – Head of Protocol at Kaleido, articulates his knowledge concerning enterprise implementations of smart contracts and how Kaledio accelerates adoption through a full-stack marketplace of protocols and tools for full-scale development. Chainlink is already offered on the Kaleido marketplace.

Hedera & Chainlink: The PB&J of Smart Contracts

Cooper Kunz – Software Developer at Hedera Hashgraph, gives an overview of the unique features of Hedera Hasgraph such as fast consensus, regulatory compliance, flexibility features like admin settings, and their consensus as a service model.

“To be concise about why I think Hedera Hashgraph and Chainlink are the PB&J of smart contracts, it’s a friendly, standardized, cheap, easy-to-use solution for any type of enterprise smart contracts or oracles you’re trying to use. There’s a rich ecosystem with Chainlink and Hedera provides a lot of the administrative flexibility for the enterprise side.”

Boson Consensus: Scaling EVM via Sharding

Qi Zhou – Founder & CEO of Quarkchain, demonstrates in great detail the powerful sharding technology of Quarkchain and how it may scale Ethereum without sacrificing the key value of decentralized security. Quarkchain already announced it will use Chainlink oracles for off-chain data.

Putting it All Together: Understanding the DeFi Landscape

Kyle J Kistner – Co-founder of bZx, gives an all-encompassing overview of the DeFi landscape based on the amount of decentralization present in each protocol when it comes to custody, initiating margin calls, margin call liquidity, price feeds, interest rates, and development. A must watch for understanding DeFi and why decentralizing price feeds via Chainlink oracles is vital for it to thrive.

SkillZ: the Decentralized BaaS Platform

Laszlo Szabo – CEO of SkillZ, expresses its vision as a decentralized BaaS Platform and how Chainlink connects SkillZ BaaS layer 1 infrastructure with to SkillZ Dapps so they can quickly and securely transport data between each other.

Get historical Blockchain & Market Data within Ethereum

Trevor Clarke – VP of Product at Amberdata, gives a quick introduction of Amberdata and the various datasets they provide: market data from several exchanges, token transfers, contract events, token prices, and snapshots of order books, as well as various ways of accessing it.

eth.events for Oracles, Dashboards, and Alerting

Peter Eulberg – Co-founder & CEO of eth.events, outlines numerous Ethereum datasets they provide, while also introducing a number of use cases from monitoring smart contracts, cross-chain bridges, and Chainlink nodes to creating dashboards that track DAOs.

Build and Operate Layer-2 dApps on Celer Network

Qingkai Liang – Co-founder & VP of Product at Celer, presents the advantages of off-chain scaling through layer two solutions like Celer. He also showcases how on-chain oracles via Chainlink can be used to direct conditional off-chain payments on Celer. In fact, there are currently two Dapps on Celer already leveraging this combination: Air prediction – a prediction market, and Micro-subscription – SLA contracts for cloud services.

Sergey’s Presentation on the Web3 Mainstage: Securely Connecting Smart Contracts to Off-chain Data and Events

Our CEO Sergey Nazarov gave a widely anticipated talk on the Mainstage about the evolution of smart contracts, the importance of trusted oracles, and the unique features that Chainlink provides to ensure that obtaining off-chain resources is just as reliable and secure as the underlying blockchains.

A big thank you to everyone that participated in the event! We are thrilled and humbled to have a rapidly expanding community of enthusiastic supporters building around Chainlink. We know through your help that it’s only a matter of time before connected smart contracts become part of the backend infrastructure powering major industries around the world.
