This is my public key:
`4104678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef38c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5f`
It demonstrates the principle of transparency and trust in Bitcoin. From this public key, one can derive the Bitcoin address as follows, ensuring anyone may verify its ownership and history.
Derivation Steps:
1. Compress the Public Key:
Since this is an uncompressed public key (hex starts with `04`), we compress it by taking the x-coordinate:
`04678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61`
Determine the prefix (`02` if the last byte of the y-coordinate is even, `03` if odd). Here, it's `03` because the y-coordinate is odd.
Compressed public key: `034678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61`
2. SHA-256 Hash of the Compressed Key:
`SHA256(034678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61)`
3. RIPEMD-160 Hash of the SHA-256 Hash:
Result: `00` (prefix for mainnet Bitcoin address) + RIPEMD-160 output.
4. Base58Check Encoding:
Apply Base58Check encoding to the result to produce the wallet address.
Using this derivation method, the Bitcoin wallet address generated from the public key is:
`1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa`
This address, derived from my public key, is the genesis address of Bitcoin—a symbol of the trustless and decentralized system we have built together.
