How did this transaction burn BTC?
OP_RETURN outputs
OP_RETURN is a provably unspendable method that allows embedding of arbitrary data into the blockchain1.
OP_RETURN outputs are used to embed data such as messages, commitments from systems like Stacks2, or even files - there are no constraints on the nature of the data, only on the size per OP_RETURN output.
As they are provably unspendable, OP_RETURN outputs are pruned from the UTXO set automatically and do not contribute to the UTXO set size.
Although OP_RETURN outputs are exempted from the Dust Limit and can be 0-value, some users choose to transfer BTC to the output. This BTC is permanently and irreversibly lost, and reduces the circulating supply of Bitocin.
Burn Address
Bitcoin addresses are generated by base58 or bech32 encoding the hash of a public key or script, along with a version and checksum.
As the encoding is directly performed on this hash value, it is possible to generate a valid address for which the pre-image public key or script is unknown. This is known as a burn address.
This is commonly done to create a visually distinct address, and to demonstrate some level of “nothing up my sleeve” transparency. The hash values are picked to be values that are improbably to have been generated by chance (due to the immense computational power required to find a pre-image that hashes to a specific value).
While some burn addresses were used in Proof-of-Burn schemes, the majority of burn addresses are simply vanity addresses used to simply burn coins or encode a message into the blockchain.
