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

7:00pm to 7:30pm - Wrap up
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 define and examine what makes a secure oracle mechanism reliable enough for external data delivery, access to web APIs 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 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 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 with Chainlink and Celer Network, including AirPrediction and Micro-Subscription. We look forward to seeing more projects building jointly at ETHDenver.
