- 1. iExec V3: A Decentralized Approach to Dataset Monetization Eth. Dev. Conf. Seoul, Korea, 28 Mai, 2019 Gilles Fedak, Eric Rodriguez, Victor Bonhomme gf@iex.ec
- 2. Agenda Why data monetization matters. Blockchain-based decentralized marketplace iExec architecture Use-cases Conclusion
- 3. Data is the new Gold !
- 5. Preserving Data Ownership and Sovereignty ● Data privacy, ownership, sovereignty is becoming a main concern ● Web3.0 gives more control over user data. ● Today we talk about Data Renting https://101blockchains.com/web-3-0-examples
- 6. iExec - Timeline ICO - 04/17 Off-chain computing SDK, Dapp Store, Dapp Challenge 87M RLC issued 10k BTC raised V1 - 11/17Background 15 years in cloud computing & HPC V2 - 05/18 V5V3- 05/19 Data Store Data Renting - Lightweight workers - Mainnet Marketplace fog/edge computing for IoT GPU Bags of Task Side chain V4 -end 19
- 8. Blockchain-based Decentralized Cloud Computing ● Decentralized marketplace for computing resources (servers, applications, datasets) ● Use Ethereum to advertise/provision computing resources ● Providers can interact in a P2P way, without central authority DATA PROVIDERS SERVER PROVIDERS APPLICATION PROVIDERS Why Does it Matter ? ● Decentralized applications need an infrastructure ● Cheaper, greener, more efficient than traditional centralized Cloud
- 9. The iExec Token: RLC Token usage ● The RLC Token is the only way to access the iExec decentralized cloud ● Providers are paid with RLC ● Allows to build incentives in the network. ● Issued on main net on April 2017
- 10. Trust Trust level parameter Decentralized by design Proof Of Contribution https://medium.com/iex-ec/poco-series Providers
- 11. Proof-of-Contribution staking + reputation + result certification: • A confidence threshold is associated with each requested execution • Workers have a reputation • Before executing a task, workers commit a security deposit (stake) • The execution confidence threshold is computed by comparing results and computing a function of the credibility and stake • Task is duplicated as long as the confidence threshold is not met • Workers who computed an erroneous results loose their stake • Workers who correctly compute gains the payments + the losers’ stake • Reputation is adjusted
- 12. iExec End-to-End Trusted Execution with Intel SGX Enclaves: Confines execution and data within a encrypted environment: no one can access/tamper the execution ● SDK that provides full end-to-end privacy preserving computation ○ for application/input/results ○ guarantee execution integrity ○ provide on-chain enclave execution attestation
- 13. Ensuring Data Privacy Trusted Execution Environment 1. Encrypted INPUT 2. Encrypted processing 3. Encrypted OUTPUT
- 15. Use Case 1 E2E Data Privacy for Healthcare Application
- 16. Nilearn: a framework from Neuro imaging Demo RSAConference 2019: brain scans with diagnostics. Privacy preservation for data and requester.
- 17. Use Case 2 Monetize IA trained model in computer vision
- 18. The data renting concept INPUT OUTPUTPROCESSING Data ● trained model ● pretrained model? ● dataset Application ● ML framework ● load model ● call prediction function Value +++ Value +
- 19. Monetize AI model in computer vision a generic framework? in a web application https://nsfw.app.iex.ec make a prediction run an application trained model = dataset get the result ● classification ● score ● object detection ... Input data
- 20. Use Case 3 Decentralized Oracle: monetize Web2.0 information on the blockchain
- 21. Doracle ● Allows to fetch off-chain information. ● Bridge Web2.0 and Web3.0 ● Decentralized: censorship resistant Build your own Doracle !
- 23. Conclusion
- 24. Share your computing resources: dApps or datasets Easy build... for awesome features AUTOMATIC PAYMENTS PRIVATE RUN SERVERLESS ACCESS CONTROL FINE TUNE PRICING / PAY PER TASK Few line of codes Blockchain complexity is hidden
- 25. IEXEC DOCUMENTATION https://docs.iex.ec/ TUTORIALS https://github.com/iExecBlockchainComputing/apps ANY QUESTION? https://iex.ec/
Editor's Notes
- Thank you very much fo the introduction and the invitation. It’s a great honour to be here. in this talk, I will introduce our new vesion 3, with a focus on decenetralized marrketplace for datasets
- The amount of data generated by the humnkind is gowong exponentially. That was the web, information published on-line, then social interaction. In the future, we will see more and more devices connected to the Internet that will generate huge amount of data. So need for decentralization, we cannot store and process everything in the centralized Cloud
- Today main problem issue is that our data are handled by centralized authoities: eitheir Cloud poviders, or application: Facebook, Google etc. And what we want today is to get control over our data again. This is the promise of web3.0. We want decentralized processing for data. This as business impact. Today, I want to introduce you a new concept: data renting. You keep ownership of your data and you monetize the usage of your data. This is possible thanks to decentralization, because you control your data, and not someone else.
- To introduce iExec. I Was researcher with 15 years background in Clould and HPC. Did our ICO. 25 people. 2 weeks ago we released V3. Mainnet
