Artem Chystiakov(@Arvolear):Damn vulnerable Simplicity covenants #4. Timelocks are ambiguous. Nodes interpret them differently depending on the tx value passed. If v < 500_000_000, it's a block height; otherwise, it's a timestamp. Be careful designing locking covenants. Unexpected unlocks may occur.
