Towards Stronger Blockchains: Security Against Front-Running Attacks. (arXiv:2311.10253v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
Blockchains add transactions to a distributed shared ledger by arriving at
consensus on sets of transactions contained in blocks. This provides a total
ordering on a set of global transactions. However, total ordering is not enough
to satisfy application semantics under the Byzantine fault model. This is due
to the fact that malicious miners and clients can collaborate to add their own
transactions ahead of correct clients' transactions in order to gain
application level and financial advantages. These attacks fall …
