Bias via Abort

In the commit-then-reveal protocol each user chooses a secret and shares their commitment to the secret with other users. Later, users reveal their secrets and a random value is calculated by combining the secrets. This approach is susceptible to attacks where a user can choose not to reveal their secret to bias the randomness generation to their advantage "bias-via-abort"
