@whitequark@jm there are better solutions to the double spending problem then a lottery for completing a proof-of-work function first -
@bascule@whitequark Yeah the more I’ve learned about the algorithm behind btc, it seems a little suboptimal. :) -
@jm@whitequark one alternative is to leak a user's private key if they double spend -
-
@whitequark@jm make double spending nonce reuse with any *DSA, which Bitcoin already uses. It's catastrophic (see e.g. PS3 master key) -
-
@whitequark@jm i.e. if double spending is detected, identify the culprit in the DAG and blacklist his whole spending history - 7 more replies
