ECDA Signature that proves that I don't know the private key ;-)
Raw
ECDSA-sig-proof-no-key.md

A small ECDSA riddle.. ;-)

Message:

**********************************************************************

With this signed message, I, johnzweng, prove that I am NOT in possession of the private key of the signing address.

Not only do I claim this, no, this signed message proves this fact cryptographically beyond doubt. I have created this signature without outside help, yet I cannot know the private key of the signing address mentioned below.

The content of the above statement is true, yet this signature is valid. You are welcome to check this yourself, in the Blue Wallet or Electrum or online, e.g. here: https://tools.qz.sg/

**********************************************************************

And here are a few digits for your entertainment: ;-)
