["research"] timestamp dependence / transaction-ordering dependence

[quinn-dougherty]

Description

Can dishonest miners game the order in which transactions are processed?

Deliverable

• yes/no
• if yes we may want to have an audit section detailing what this attack would look like on Danaswap.

Notes

See book by Ma-Gorzny-Zulkoski-Bak-Mack for information on timestamp dependence attacks

The Cardano mempool is designed to be "fair". Transactions are processed in a FIFO order regardless or how much in fees they pay (the ledger spec does support a fee market, but cardano-node doesn't take this into account)

This is currently listed in I.3. Insufficient literature because cardano-node commenter SebastienGllmt is the only source I've found, and subsequent commenters on that thread called into question some of their assumptions.
