Contract as a Deal Client for Archiving Filecoin Blockchain Message Data

Motivation

1. Use web3 infrastructure to solve the filecoin message archive problem currently solved with web2 clouds
2. Provide an EVM contract template for contract as a client data storage on the filecoin network
3. Identify sticking points in the current model of data preparation, data transfer and deal negotiation for contract as a client storage deals. For example learn how the ask protocol should change to support this model.
4. Demonstrate a new model for FIL+ auditing with significantly better fraud resilience properties

The core idea is that as system and protocol developers we will benefit from building a small application to understand how to adapt the network to similar applications. The nice thing is that fil infrastructure has a concrete application today which serves PLs broader goal of using our own tech.

Run a lotus node and sync the filecoin blockchain up to the height you want to validate

One way to see how far you've synced is to inspect the output of ./lotus sync wait

Get the inspection-cid

"inspection-cid" is the cid of the block header at inspection-epoch, the epoch whose parent state you want to validate.

By Using the lotus daemon

1. ./lotus chain head to get your node's current head if inspection-epoch is head height. A list of cids is output, copy one of them.
2. ./lotus chain list --height=<inspection-epoch> --count=1 if head is above inspection epoch. A list of cid to miner mappings is output, copy one of them.

By Using filfox

Navigate to https://filfox.info/en/tipset/<inspection-height>
