Join us at the Chainlink and Celer #BUIDL Denver meet-up to discuss the powerful combination of real-world information with layer-2 scalability. Each team will present their project and how it tackles blockchain security, scalability, and the use of external data to execute on-chain events.

Presentations

Chainlink

Smart contracts are tracking to be the leading form of digital agreements for key global industries. The vast majority of useful smart contracts extend beyond the blockchain to connect with external sources, including data feeds, web APIs, and traditional bank payments. These connected smart contracts access information feeds, such as stock prices for financial trades, weather data for insurance contracts, server uptimes for SLAs, and much more.

However, to maintain a connected smart contract’s overall reliability, the inputs and outputs to the contract also need to be secure. In this talk, we’ll examine what makes a secure oracle mechanism reliable enough for external data delivery, web API access, and off-chain payments.

We’ll explore how decentralization can make oracle mechanisms more secure and also present in-depth approaches that apply additional layers of security through the use of Trusted Execution Environments and cutting-edge approaches like TownCrier.

Despite its potential, off-chain scaling is still in its infancy with many challenges that remain 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 easily build and operate scalable off-chain dApps? How to guarantee that off-chain states are always available for possible disputes?

In this meetup, we 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. We provide our vision for Celer Network 2.0, a grand unification of all off-chain scaling technologies into a single solution.

At ETHSF Hackathon last fall, several winning teams built their projects with Chainlink and Celer Network, including AirPrediction and Micro-Subscription. We look forward to seeing more projects building jointly at ETHDenver.

Agenda

• 7:00 to 7:30pm - Wrap up

Speakers

Dan Kochis, Global Head of Business Development for Chainlink

Dan has a long history of closing deals that help companies reach their next stage of growth globally. He was integral to Alibaba's first US acquisition, various worldwide strategic partnerships worth over $120MM in annual revenue, and corporate exits totaling over $4bn.

Mo Dong, Co-Founder of Celer Network

Graduating with the Ph.D. from UIUC, Dr. Dong has been applying his research and engineer experience on networking protocol design, distributed systems, formal verification and Game Theory to the scalability challenges of blockchain systems. Dr. Dong led a project revolutionizing Internet TCP and improved cross-continental data transfer speed by 10X to 100X with non-regret learning algorithms. His work on this project was published in top conferences, won the Internet2 Innovative Application Award and is being adopted by major Internet content and service providers.

About Chainlink

Chainlink is a decentralized oracle network that enables smart contracts to securely access off-chain data feeds, web APIs, and traditional bank payments. Chainlink is consistently selected as one of the top blockchain technologies by leading independent research firms such as Gartner. It is well known for providing highly secure and reliable oracles to both large enterprises (SWIFT) and leading smart contract development teams.

About Celer Network

Founded by four PhDs from MIT, Princeton, UC Berkeley and UIUC, Celer Network is a leading layer 2 scaling platform that enables fast, easy and secure off-chain transactions for not only payment transactions, but also generalized off-chain smart contract. It enables everyone to quickly build, operate, and use highly scalable decentralized applications through innovations in off-chain scaling techniques and incentive-aligned cryptoeconomics. Celer Network is on a mission to fully unleash the power of blockchain and revolutionize how decentralized applications are built and used.
