Request for information about disputes #GDR-10

The arbitrators are contacting indexer address 0x4437e367cc68d87675148a9e4a1f052f0359c880 (mind-heart-soul) about disputes filed in the protocol.

To make the investigation as brief as possible, please provide the following information and any other relevant records about the open disputes:

  • Version of graph-node used.
  • Graph-node configuration in full.
  • Type and version of Ethereum node.
  • Table of PoIs generated by the affected subgraphs.
  • A dump of the call cache data from the database for the affected subgraphs.
  • Entity values as of the divergent block once identified.

This is not an all-inclusive list. Request for additional information may be made if considered necessary.

How to Get Relevant Data

You can use the following queries to extract information from the indexer software to be used in the evaluation.

# Get subgraphs schema
SELECT name FROM public.deployment_schemas where subgraph = 'QmdoTSPsdt491REYXDheBJwLvNXUvKsNGkiHJZMYNSca22';

# Move to the subgraphs schema

# Dump PoI TABLE - (from outside of psql console but on server)
pg_dump --dbname="<YOUR_DB_NAME" --host=<DB_HOST> --port=5432 --username=<USERNAME>  --table='<SUBGRAPH_SCHEMA>."poi2$"' --file='<FILE_TO_SAVE_TO>'

# Dump call cache (on some setups this table may be in a different schema, check it with `select * from public.chains`)
pg_dump --dbname="<YOUR_DB_NAME" --host=<DB_HOST> --port=5432 --username=<USERNAME>  --table='public.eth_call_cache"' --file='<FILE_TO_SAVE_TO>'

Once a divergent block is identified:

# loop through all entity tables and get changes for that block
# for each entity table in subgraph deployment schema:
select * from <entity_table> where lower(<DIVERGENT_BLOCK>);

Purpose of the Requirement

This requirement is related to the following disputes:

About the Procedure

The Arbitration Charter regulates the arbitration process. You can find it in Radicle project ID rad:git:hnrkrhnth6afcc6mnmtokbp4h9575fgrhzbay

For communications, please use this forum. Additionally, please monitor Graph Protocol’s Discord #arbitration ( ) for any arbitrator reaching out for more information.

Note: I had already previously worked with @Koen obtaining the necessary information needed to address this dispute back in April and May, but an official forum post was never made.

Indexer’s POI: 0x960dbfcc56fc6644f889d815f497deef9f30136d2339daefaa4a788f566f868a

POI match found. This subgraph error can be “bounced” past the failure block, but the subgraph will continue to fail with the same error at a later block. Because of this, there’s a chance the Fisherman wound up on a later epoch reference block than the Indexer, prompting a POI mismatch between the two when calculating the POI.

If Fisherman 0x93372d846b2f73cc34a03f44e0a9b09a037daa77 would like to provide additional info, please try to do so in short order so the Arbitration Council can address these in a timely manner.


I opened this case because I noticed that 0x4437e367cc68d87675148a9e4a1f052f0359c880 closed 6 allocations (163 epochs duration) on subgraph QmdoTSPsdt491REYXDheBJwLvNXUvKsNGkiHJZMYNSca22 with the same POI. It is indeed known that this subgraph crashes during epoch 91. Yet the indexer continued to open and close allocations, and therefore collect rewards, while there is no proof that any indexing was done/attempted during that timespan. I would expect that like most indexers, this indexer would notice the subgraph failure, and stop allocating to it within a reasonable amount of time.

Note that after those 6 allocations, 3 more were made over a timespan of 103 epochs, with 2 different POIs, then finally the same POI as the first 6 allocations. These 2 new POI values were probably due to Errored subgraphs sometimes resume correctly after restart · Issue #3236 · graphprotocol/graph-node · GitHub.
