💙FilFil: PeSto and Filecoin Archive
🧠Overview
2.5 years after Filecoin genesis, the Filecoin full chain state has grown to ~25TiB. It is almost impossible to sync the chain from genesis block, which means it is getting harder for one to access Filecoin historical chain state. More importantly, the network’s is at risk of losing full historical chain state, given less and less people maintain a full archival node!
As Filecoin developers, we believe its important to save the historical data. In this project, we will develop a Filecoin chain archive service via two main tracks:
- PeSto: Perpetual Storage on Filecoin using FVM compatible smart contracts
- FilFil: Filecoin Archive Application
🚀Goal
FilFil aims to deliver a Filecoin chain archive service that archives Filecoin chain state on Filecoin’s perpetual storage (PeSto) network.
With Filecoin Archives, one can view, query and validate Filecoin chain history from genesis for the humanity lifetime.
📡Objectives
- Deliver a set of generic FVM compatible smart contracts that support data use cases on Filecoin’s storage. Data use cases include but not limited to:
- Perpetual Storage
- Storage Automation (renew and repair)
- DataDaos
- Define protocol gaps and develop protocol refinements to enable data use cases on Filecoin storage.
- Deliver a tooling in lotus-miner that allows storage providers claim FilFil data bounties and provide storage service for Filecoin Archives.
- Develop 5 tutorials/demo/Youtube workshop that walk through how to develope and deploy FVM compatible smart contracts that works Filecoin’s storage.
- Deliver a Filecoin archive service that archives Filecoin messages on Filecoin, since genesis and onwards. The service needs:
- FilFil Contract: a FVM compatible perpetual storage smart contract.
- FilFil CID Generator: a tooling packs the Filecoin messages from a lotus chain store into .car, and generate the CID.
- FilFil CID Uploader: a tooling that uploads the CID above to the FilFil contract.
