Assumptions and Goals

• The quantum inflection point (quantum attack breakthrough) may occur when the large majority of Web3 assets and transactions are done on blockchains reliant on ECDSA.

• Web3 tokens (ERC20, ERC721, etc.) are only allowed to be bridged (e.g., via LayerZero) to a quantum resilient network, if and only if these assets have not been hijacked via ECDSA compromise. That is, this transfer must be based on a cryptographic scheme that remains secure even after the above quantum inflection point occurs.

• While users could reduce their own exposure to the attack by not reusing the same address across transactions, it is not a prerequisite for using qMig. qMig should prevent movement of stolen funds, while supporting EOAs with prior transaction history.
