On New Quantum-resilient Alternatives

Last updated 2 years ago

A notable effort to build an entirely new quantum resilient blockchain is Quantum Resistant Ledger (), which uses signatures. An affiliated project, , is a wallet implemented as an Ethereum smart contract that uses a secondary signature (XMSS), resilient to quantum attacks; the scheme relies on a Merkle tree of cryptographic hashes. The idea is to transfer your tokens into this quantum resilient vault as a means to mitigate future unexpected events, (i.e., a successful quantum attack). While this mechanism is useful to protect individual EOA, it does not deal with the resulting fallout of such an attack: a loss of confidence in a system rooted in cryptographic trust. Any further transaction signed with an ECDSA key would be suspect. Business as usual on a network in this state would cease. In case of such an event, there is a need for a mechanism that can securely move assets that belong to their rightful owner (rather than the attacker) to a quantum resilient network.
