Oasis Labs
Abstract:
Oasis Labs is building privacy first blockchain and application stack. After raising ~$45m, this is one of their first public talks detailing the latest technical roadmap.
Commentary:
Very impressive talk. Dawn proactively addresses some of the questions around relying on secured execution environment by going open sourced. Oasis has designed a very holistic vision for privacy first blockchain, on both the chain layer and application layer.
Notes:
Dawn Song
Privacy first cloud computing platform on Blockchain
Data is the new oil
Largest scale data breaches
Most data is siloed
Users are losing control of their data
Internet bill of rights
Oasis, security and privacy, high performance, machine learning
Smart contract for fraud detection
Privacy Preserving smart contract
Application layer and platform layer for oasis
Platform confidentiality preserving smart contract execution
Trusted hardware
Secure multi party computation
Zero knowledge proof
Fully homomorphic encryption
Scalable smart contract execution
Application layer,
Secure hardware
Trusted execution environment
Ekiden, Secure Enclave as a cornerstone security primitive
Open source design
Keystone, open source Secure Enclave
Risc V architecture
Privacy preserving machine learning
Can attackers extract secrets in training data
Preventing memorization
Outcome is the same with or without joes data
No previous real world deployment
Need better usability, broad support, easy integration
Scalable smart contract execution
Scalability is more than just high tps for payment transactions
Consensus is a slow operation
Sharding, coordination is expensive
Separate consensus from execution
Verifiable computing
