Decentralized IPFS Pinning Service AVS
To build an AVS in the open, via community, that enables crypto incentivized IPFS Pinning as an AVS on EigenLayer. Background here.
Story 0) Operator Registration
- Operator registers their IPFS address and IPFS peerID to their Operator Address in EigenLayer registry contracts.
Story 1) Data Submission:
- User submits an IPFS hash (CID) to an AVS contract along with a payment.
- Payment amount dictates the duration of data storage and delivery.
- All AVS nodes are expected host the IPFS Content within a specified amount of time and then deliver the content to any request in the IPFS network.
Story 2) Daily Proving of Data:
- (Note: there are many, many, many potential solutions to this problem. For now, we're starting with an example high level, simplest route to achieving these goals)
- At a regular interval (eg daily) a randomized group of nodes are chosen to be act as a "retrievability" proving committee. The committee will choose a subset of CIDs to confirm retrievablity.
- The committee will attempt to connect to each IPFS server, downloaded the file, and verify it matches the CID.
- Eg ipfs swarm connect
ipfs swarm connect /ip4/<server_ip_address>/tcp/4001/ipfs/<peer_id>,ipfs get <ipfs_file_hash>
- Committee updates the AVS contracts with the peerID, CID and success or failure of the download operation.
Story 3) Payments and Slashing conditions:
- Payments: each time interval - payments are sent to the IPFS servers listed as hosting a given CID
- Slashing: any IPFS server whom the committee records 66% failure for a given CID gets [some very small penalty, tbd, potentially slashed a small amount of their stake].
Ideas:
- Build the backend AVS code in Javascript in order to appeal to the largest audience possible.
- Reuse existing IPFS bits where possible (example).
- Build a draft AVS offline service in Javascript that listens for an event (NewDataSubmission) and pins the associated CID
- Test: setup a local Foundry Anvil test script that emits the event to trigger the CID download.
- Build EigenLayer AVS contracts to register Operators, register the AVS and custom AVS contracts to manage the state of pinned CIDs & their Operators.
- Test: modify test scripts to automate registration and and validate new contracts.
