How Does a Failure to Reveal a Transaction Affect the Overall Network’s Security?

A failure to reveal a committed transaction does not typically affect the network's overall cryptographic security or consensus mechanism. However, if non-reveals become widespread due to a design flaw that allows profitable 'griefing' (aborting unfavorable trades), it can negatively impact the network's economic security and efficiency.

It wastes block space, increases transaction fees for others, and undermines the reliability of the protocol for honest traders.
