Bacalhau Blog: CoD Summit² Day 2 - Data and Usage
All the highlights from the day 2 "Data and Usage" track of the Compute-over-Data (CoD) Summit, held at the Hyatt Regency in Lisbon, 3rd November 2022
Various project teams shared their innovations in the decentralized compute over data space on the second day of this fall's COD Summit². We had speakers covering a wide range of topics, including security, reputation, building highly scaled systems, and an example of user demand for compute over data (via the DeSci community).
Compute Over Encrypted Data
Parth Shukla from 180 Protocol took us through multiple designs for running decentralized compute over encrypted data in IPFS and Filecoin. This led to multiple discussions regarding encryption over data via Estuary, replication to Filecoin, and future tooling for Service Providers. Parth explained there are performance implications to encrypted compute, but based on their recent research with the Filecoin Foundation, benchmarking results show a relatively small performance penalty.
Decentralized Compute at the Edge with Blocz
Lee Norvall’s talk on Decentralized Compute at the Edge covered their ongoing work to help the health and safety of the City of Las Vegas. We learned how significant the cost savings can be for state and local governments when they generate petabytes of data at the edge.
What happens when you drive a truck into an edge compute location? Decentralization! Having multiple regional backups ensures the customer is not dependent on the availability of a single centralized location.
Aleph.IM and Using IPFS to Decentralize Backends
Hugo and Olivier took us through their designs to offer long-term guarantees for backend applications, similar to the durability of smart contracts.
The initial design is to support Lambda functions and micro-VMs invoked on demand. Their architecture had a dual network design: one for publishing messages and the other for compute execution.
For privacy concerns, there were discussions around when to trust the node operator vs when to trust the VM secret store for server-side VM secure computation (e.g. AMD Trusted Execution Environments).
SaaS Service Models via Smart Contracts on FVM
Taosheng from Ken Labs discussed how SaaS-style services can be built with Smart Contracts on FVM. Many projects are thinking through how they can find the right economic incentives for their communities.
