control?]({{bse}}89508) Andrew Chow explains that since a hardware wallet is
not a full node, it needs to get its transaction amount information elsewhere.
In the case of non-segwit inputs, often the amount is provided to the hardware
signing device by the host computer or wallet including the previous
signing device via the host computer or other wallet by sending the previous
transaction to the device. In the case of segwit inputs, the amount for the
input being signed is actually part of the data that is being signed.
input being signed must always be provided because it is a required part of
the data that is signed and verified.

- [How does one prove that they sent bitcoins to an unspendable
wallet?]({{bse}}89554) JBaczuk explains three ways to prove coins are
unspendable. These include: sending the coins to an OP_RETURN output, sending
coins to a script which returns false, or sending coins to an address derived
from a contrived, non-random script hash.

unspendable by sending the coins to an OP_RETURN output
or another script that always returns false, or by sending coins to an

- [Why is proof-of-work required in Bitcoin?]({{bse}}89972) Pieter Wuille
explains that PoW does not create trust, but instead creates incentive for
miners to cooperate with other miners by building on their blocks. PoW is also
used to regulate block times (and thus protect against denial of service)
since the difficulty adjustment makes it expensive to reliably produce blocks
more often than, on average, every 10 minutes.
