Statistics Transaction Fees

Goals

The goal of this service is to calculate fees from account_transactions for each day.

Data used

We use all transactions from the transactions collection and the aggregate information on blocks from the block_per_day collection.

Calculations

The following pipeline is executed on the transactions collection. Note that it only looks for account_transactions, as update and account_creation do not generate fees.

            pipeline = [
                {"$match": {"account_transaction": {"$exists": True}}},
                {
                    "$match": {
                        "block_info.height": {
                            "$gte": height_for_first_block,
                            "$lte": height_for_last_block,
                        }
                    }
                },
                {
                    "$group": {
                        "_id": None,
                        "fee_for_day": {"$sum": "$account_transaction.cost"},
                    }
                },
            ]
