0203 - Protocol cutover away from ECDSA using private-key reveal to move assets
Summary: A network-wide transition mechanism that deprecates ECDSA signatures after a specified block height. Assets tied to ECDSA-derived addresses can be moved by committing using a one-way function applied to the ECDSA private key and then revealing the private key to validate the commit. Validators confirm the private key derives the original address before applying the transfer to the new quantum-resistant address form.
