RFP: New RFP Ideas for Wave 3

Name of Project: Simple Storage webapps

RFP Category: app-dev

Proposer: [@DecentralTech]

Project Description

Single page apps that demonstrate using Filecoin to store and retrieve files. Example workflow: drag + drop a file, pay to store it, retrieve it. Show miner info, CIDs. One version could eli5 (explain-it-like-I'm-5) to new users as a tutorial or tour. Your proposal should provide examples of applications and interfaces your team has built and links to their code repos. Also see Filecoin community resources for an initial list of Filecoin developer tools.

Outcome

• File network disk, refer to the IPFS WebUI demo, without registering the login system, allowing users to upload files, view uploaded files, and obtain files
• The function relies on the filecoin chain to interact with the chain instantly

Name of Project: Filecoin Chain State Explorer

RFP Category: app-dev

Project Description

An interactive visual tool to dive into the Filecoin state trie would help protocol developers and researchers do in-depth analysis. The 1st level could be an interpretation of the actual tree and include key Actors, a map of the HAMT data structure, etc. Currently a latest trie snapshot is ~10GB. Also see the RFP for Diagram the Filecoin blockchain

Existing tools:

• The lotus node implementation of Filecoin has a Postgres database tool called chainwatch on top of which a visual chain explorer has been built.
• Several block explorers for Filecoin (filscan.io, filscout.io, filplorer.com) have been developed
• Filecoin’s state trie is unique but this Ethereum state trie diagram provides an example of what may be involved Preferred applicants should be able to work independently and learn how the Filecoin state trie is structured using the Filecoin Specification and the various Filecoin node implementations.

Outcome

• Interactive and high performance chain data tree explorer
• Along with updated filplorer.com

Team

(Filplorer.com was built by our team previously, chain state explorer is planned to updated upon filplorer.com)

Name of Project: Diagram the Filecoin Blockchain

RFP Category: app-dev

Project Description

Diagrams of the Filecoin blockchain at the level of detail and visual quality of Lee Thomas’ diagram of the Ethereum Yellow paper and state trie [ Source ]. Preferred applicants should be able to work independently and learn how the Filecoin blockchain is structured using the Filecoin Specification and the various Filecoin node implementations.

Outcome

• Very clear diagram explanation of Filecoin blockchain
• Maintenance of long-term update of technical specifications

Name of Project: Web archiving browser extension or Twitter bot

Project Description

A browser extension that allows users to archive websites to IPFS and backup to Filecoin. This extension could also provide a Filecoin wallet so that users can pay for archival and as a way to keep track of what they have saved. In the future this could be expanded to ways to collaborate on and share archived bookmarks in online communities or as bookmarking services (e.g. Pinboard , Pinterest, etc.) A Twitter bot such as the former Link Archiver could automatically archive websites from tweeted links. This project would need to explore the required infrastructure for these services.

Outcome

• Current page content generate html files and save it on IPFS. Filecoin Deals was optional for users
• .No Filecoin Wallet included but wallet API set aside, because found some other team have proposed Filecoin Wallet
• Chrome and Firefox extension
