Did you miss the latest monthly core devs meeting?

Developer updates, discussion on the Solana integration & the role of The Graph in EIP-4444 were covered. Watch the full meeting here:

Read on for the highlights!🧵

@edgeandnode

Indexers should update to the latest versions of indexer-service & graph-node!

GIP-0020 has been implemented, allowing indexers to quit executing a query without risk of slashing.

Planning is in progress for graph-node to support multiple file data sources.

@Figment_io

Figment is working to integrate Tendermint within graph-cli. Tendermint packages networking & consensus layers of a blockchain into a generic engine. It’s a first step towards Cosmos ecosystem integration.

Cue a two-week multi-node test 🙏

@streamingfastio

Indexers should implement the Firehose, if they are able to!

The Firehose is in development for BSC & the team is currently ensuring the Firehose works with Ethereum call handlers. The team is working on solutions for Solana too.

@TheGuildDev

The Guild, a member of the GraphQL Foundation, is composed of developers that build open-source GraphQL tools.

As a recent grantee, The Guild built a Schema Prototyper for The Graph. The team is now focused on shifting towards API versioning & subgraph composition.

@semioticai

Semiotic, another recently announced grantee, shared an update on their work as well. The AI & cryptography team is focusing on verifiable queries with optimized zkSNARKs libraries & decentralizing query cost prediction with neural networks.

@LimeChainHQ

LimeChain, the developers behind Matchstick, developed a subgraph debug tool that saves subgraph developers precious time!

It runs the failed block locally so developers can receive feedback on fixes fast. The tool has been finalized & is part of graph-node.

As for Ethereum — EIP-4444 is a compelling opportunity for The Graph. As part of the push for Ethereum 2.0, EIP-4444 introduces historical data pruning in Ethereum clients. This will benefit validators, add capacity for rollups, increase throughput, & reduce transaction costs.

EIP-4444 will also support greater decentralization, ensuring consumer grade hardware can be used to validate the chain. The proposal leaves a gap—surrounding historical data—that The Graph can fill.

Because historical data will no longer be available, some functionality for Ethereum clients would be removed. The Graph can address this by indexing historical data from genesis & serving queries for that data.

An Ethereum Network Subgraph will need to be built that will index all the relevant data & thereby be able to mimic the JSON RPC API with more advanced filtering, sorting & pagination.

Second, The Graph needs to support higher levels of verifiable indexing & verifiable queries. Everything that would be utilized by the Ethereum Network Subgraph would need to have a 1 of N trust model. This level of verifiability is already being worked on.

On to the Solana Integration.

Solana is a fast chain. It produces gigabytes of data per day, sometimes more! This produces a challenge for Indexers who can't sync data from genesis & will need access to that data.
