Bitcoin key. I know that Bitcoin keys are important for cryptocurrency transactions, but I am specifically curious about the length or size of a public Bitcoin key.

Compressed public keys are more compact, measuring exactly 33 bytes in length.

These keys feature a specific prefix, which can be either 0x02 or 0x03, depending on certain cryptographic conditions.

Following the prefix, a 256-bit integer known as 'x' is included, forming the remainder of the compressed key.
