TIL in 2011 a user running a modified mining client intentionally underpaid himself 1 satoshi, which is the only time bitcoin have ever truly been destroyed.

In block 124724 you'll find txid 5d80a29b which has a payout of 49.99999999 BTC at a time when the block reward was 50 BTC. A transaction fee of 0.01 BTC was also forfeited. This bitcoin no longer exists anywhere in the network, as opposed to "burned" coins which technically still exist in a wallet which no one can ever access (ex: 1BitcoinEaterAddressDontSendf59kuE).

On bitcointalk user midnightmagic explains a deeper meaning behind this:

I did it as a tribute to our missing Satoshi: we are missing Satoshi, and now the blockchain is missing 1 Satoshi too, for all time.

Bitcoin – The Currency of the Internet

When comparing the Lightning Network to the legacy payment systems, all detractors either miss or intentionally leave out the most important distinction that gives LN its major advantage —> **Zero counterparty risk**

Unlike the bank (or anything we’ve previously known), with the Lightning Network the other party can’t decide not to give you the money they owe you. A blockchain confirmation will always set the record straight. Unlike the bank, the Lightning Network involves zero trust in the other party to give you your funds.
