How did this transaction burn BTC?

The Empty String Public Key

The address 1HT7xU2Ngenf7D4yocz2SAcnNLW7rK8d4E is a Bitcoin address derived from an empty "" string as its public key. Wallets with bugs, including Bitcoin Core¹, have at times attempted to derive an address using ripemd160(sha256("")), which producees 1HT7xU2Ngenf7D4yocz2SAcnNLW7rK8d4E.

As it is impossible for any private key to result in an empty public key, this address is provably unspendable.

ECDSA Incompatibility

The Bitcoin Protocol relies on the secp256k1 elliptic curve for its cryptographic operations. This curve belongs to the larger family of elliptic curves.

Bitcoin also employs a number of hashing operations such as SHA-256 and RIPEMD-160. These operations are used in various places across the protocol, including in the creation of addresses and their corresponding Bitcoin Scripts.

In some cases, it is possible to select values that are invalid for the secp256k1 curve as inputs to the hashing operations. This can lead to unexpected results, such as the creation of addresses that can be used to receive BTC, but are never able to spend it.
