Open Grant Proposal: Lighthouse FVM Tooling

Project Name: Lighthouse

Project Summary

This project aims to make tools for developers to use FVM easily and build on Filecoin with the best developer experience. Many developers are already building on FVM, and many more are interested in building new dapps leveraging the power of programmable storage that FVM has to offer.

This proposal consists of new developments made by the Lighthouse team that provide the ability to verify storage via PoDSI (proof of data segment inclusion), implement the RaaS full interface, and the upload interface with interaction via contracts deployed on Filecoin Virtual Machine. This proposal takes into consideration the feedback from the FVM community in past events and makes sure that developers in upcoming events can leverage the full power of verifiable and programmable storage ability provided by FVM.

Impact

1. Solves pain points of developers building on FVM and prepares the right developer experience for upcoming events like Open Data Hack
2. It benefits the whole Filecoin economy by providing the best set of tools and interfaces to build on FVM (Filecoin Virtual Machine).

Outcomes

1. PoDSI (Proof of Data Segment Inclusion) endpoint for Open data hack event as documented here. Proof of data segment inclusion is used to prove that your file is in the deal created by the aggregator node. The aggregator provides aggregated files, piece CID, inclusion proof, and proof of sub-tree
2. Integrate the RaaS interface as defined by the FVM Team specs

• Make formatting edits to align with the aggregator interface defined here

• Test deal replication and add documentation for Open data hack

3. The upload interface will be added according to the below spec

• data_url: an https or ipfs link to fetch a copy of the data if the data is not provided as a binary in the API call
• (optional) miner: id address of the miner that the user prefers to use (optional in upload) num_copies: the number of copies that the user wants to replicate (default: 3)
• (optional in upload) repair_threshold: the number of epochs that the sector has to be in “inactive” status before the worker repairs the deal
• (optional in upload) renew_threshold: the number of epochs that the deal is about to expire

4. Provide clear documentation for developers to interact with the FVM for PoDSI and RaaS interface

Adoption, Reach, and Growth Strategies
