Plutus Scripts Evaluation

Tools used to:

  1. Accumulate Plutus script evaluation events by replaying blockchain folding over the Ledger state and extracting PlutusScriptEvaluationEvents.
  2. Record accumulated events:
    1. On the file system as "dump" files.
    2. In the PostgreSQL database.

How to use

  1. Initialise the PostgreSQL database and connection using files in the database folder:
    • There is a pgModeler (Open-source tool) project for it,
    • As well as the DDL statements.
  2. Create .envrc.local with the following content (adjust the paths as needed): 
     export CARDANO_NODE_SOCKET_PATH="/home/projects/cardano/node/node-state/mainnet/node.sock"
 export CARDANO_NODE_CONFIG_PATH="/home/projects/cardano/playground/docs/environments/mainnet/config.json"
 export DB_CONN_STRING="dbname=mainnet_plutus_events"
  3. Enter the nix shell using either nix develop command or direnv hooked to your shell.
  4. See available commands by entering info in the shell.
  5. Run the script dump job using the dump command or script upload job with the load command.
