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.
