GGP 0022: Update Feature Support Matrix to support Celo, Arbitrum, Avalanche + File Data Sources (IPFS)
Summary
This is an update to the previously ratified Feature Support Matrix included in GGP 0018.
This proposal updates the subgraph API Feature Support Matrix to include new Data Sources, Data Source Features, and the minimum required Graph Node version (v0.30.0).
New Data Sources
The following chains are supported by ratified EBOs living on Ethereum mainnet and Arbitrum One.
eip155:42161(arbitrum-one)eip155:42220(celo)eip155:43114(avalanche)
Note: Due to timing constraints imposed by the MIPs program, support for these chains has been added on February 24th, following an offline vote from Council members and the signing of the corresponding Defender transaction. Moving forward, official technical support for new chains will only be added after an officially approved GGP.
New Data Features
File Data Sources: IPFs
Core developers who worked on this new feature are proposing support for Indexing Rewards. indexing will still support arbitration and slashing (same as Full-text Search). Quoting Zac, from Edge & Node:
Subgraphs with File Data Sources (FDS) may have both on-chain and off-chain logic. The way that (FDS) works is that the off-chain data is “isolated” from the off-chain logic.
So, all of the off-chain logic is deterministic.
We decided to enable rewards for the deterministic off-chain portion by, for now, only rolling the on-chain data into the PoI. So, an Indexer can submit a PoI for the off-chain portion and collect rewards.
Graph Node v0.30.0
Support for File Data Sources: IPFS is introduced with Graph Node v0.30.0, released Feb 17th. Release notes here.
Graph Node v0.30.0 is now the recommended version for mainnet (PR here). Starting February 22, 2023, this version is being tested by E&N Backstop Indexers on Goerli. This PR also points to the updated Feature Support Matrix (full copy below), which will remain open until ratified by the Council.
Feature Support Matrix
The Feature Support Matrix can be found below and has already been merged in this PR, which can be reverted. This makes it the latest canonical Feature Support Matrix. Moving forward, PRs and required software changes will happen only once a Matrix is officially ratified by the Council by means of a GGP similar to this one.

No new Defender transaction will need to be signed except if there’s a need to revert the proposed (already in effect) Feature Support Matrix.
