Data Model

• transaction data (irrespective of block inclusion):
  • transaction_slot: (banking stage only!), transaction from banking stage plugin; reflecting errors trying to include transaction in block (block is designated by slot)
  • accounts_map_transaction: mapping of accounts to transactions irrespective of block inclusion
• related to a produced block (happens after transaction data):
  • transaction_infos: transaction in blocks
  • accounts_map_blocks: accounts mentioned in block
