Sergey Nazarov, CEO of Chainlink: Smart Contracts 101Sergey Nazarov is the CEO of Chainlink, one of the most interesting companies in the smart contract space. He's been building blockchain smart contracts since 2011, and this is definitely the most in-depth we've gone on the topic. Sergey is a firm believer that crypto has the ability to change the way societies distribute wealth, enforce contracts, and share critical information.

The future of smart contracts with Chainlink - Gossip About Gossip80% of smart contracts need external data, but without an oracle, the data is stuck in silos. Johann Eid from Chainlink shares more about the future of smart contracts as the primary method for establishing digital agreements and explains why Chainlink is integrating with technology like Hedera Hashgraph.
In May 2019 Hedera Hashgraph and Chainlink announced they will integrate Chainlink’s decentralized oracle network with Hedera’s enterprise-grade distributed public ledger.

Chainlink for Ethereum Mainnet Announcement at Consensus 2019Sergey Nazarov announces at Consensus 2019 that Chainlink for Ethereum Mainnet is launching May 30th. He also shares vision for Chainlink's goals beyond going live on Ethereum:
1) create marketplace for all smart contract inputs and outputs
2) support all smart contract networks that hold value and need oracles
3) provide the most secure blockchain middleware using decentralization, TEEs, and multiple other approaches
Chainlink is a decentralized oracle network that enables smart contracts to securely access off-chain data feeds, web APIs, and traditional bank payments.

From Bad Word to Buzzword: How we went from No-chain to BlockchainA talk by John Wolpert at Tulip Conference 2019 in San Francisco.
John Wolpert is the Product Executive and Seeker of Awesomeness at ConsenSys Web3Studio. He is helping to start the next wave of companies on Ethereum and the emerging decentralized Web.
In this talk, learn how blockchain is about to go from a “bad word” to essential ingredient in every integration.
Ari Juels: Using Hardware Enclaves to Provide Trusted Data to Smart Contracts (Episode 164)Support the show, consider donating: 14PRgGymfhzY19Jw7x3T9DrXD5Jjxo76JV (http://bit.ly/2hgRr1l)
One of the shortcomings of decentralized smart contracts is their inability to retrieve information from the outside world. The deterministic nature of Etehreum-style blockchains makes it impossible for them to incorporate functions allowing them to do things such as make API calls to websites and data feeds. Though oracles are often cited as the solution to this problem, they require users to place a high level of trust in their operators, a model which would undermine the very nature of a decentralized smart contract.
Ari Juels, a Professor at Cornell Tech (Jacobs Institute) and former Chief Scientist of RSA, joins us to discuss his work on Authenticated Data Feeds for Smart Contracts. These 'Town Crier' feeds would act as bridges between smart contracts and websites, srapping data over TLS and feeding to to a smart contract. Relying on sophisticated hardware enclave technology (Intel SGX), one who uses a Town Crier feed would not need to trust its operator as code execution would be guaranteed signed by the hardware.
Topics discussed in this episode:
- Ari's background in cryptography and cryptocurrencies
- The pain points with oracles as we describe them today
- The idea behind Authenticated Data Feeds
- The hardware and software architecture of the Authenticated Data Feed model and how hardware isolation works
- How Authenticated Data Feeds could be used to create criminal smart contracts
- The differents ways in which criminals could use Authenticated Data Feeds to release bounties for crimes such as private key theft or even murder
- Countermeasures which may prove effective in fighting criminal smart contracts
- The Initiative For Cryptocurrencies & Contracts (IC3) and its raison d'être
