@metamitya I would like to learn (technically) how this up valuing and locking is done in code.
Is locking (just) as simple as a transaction with nLocktime engaged and after x blocks returns the sats back to the wallet they came from?
Is up valuing (just) a transaction of x sats from ones wallet to the post owner's wallet?
