Court lambda functions

Kleros Court Functions

put-justification

• Checks the justification signature for validity and adds the justification to the database
  • Address recovered from signature must be valid and the corresponding votes must not have been casted.
• If it receives derivedSignature it adds it to the derived account database

get-justification

• Returns justifications for corresponding dispute round

get-dispute-metaevidence

• Fetches metaevidence uri from subgraph or database
• Often the metaevidence uri is emitted before any interaction with KlerosLiquid. Thus the subgraph will not be able to index it
  • When this is the case, metaevidence uri from database is fetched. This is because getLogs calls take long (too long for a simple serverless function to handle) and are not very reliable so we cache the uris on Supabase.
  • When a new uri is fetched but not found in the database (because it has not been yet introduced), we call the notice-metaevidence-background bg function

notice-metaevidence-background

• fetches the metaevidence uri via getLogs and introduces it into the database
  • uses multiple batches for faster concurrent fetching
