The developers of Solana **created** Quantum-resistant Winternitz Vault to protect users from the threat of quantum computing – it uses hash signatures, generating new keys in each transaction, making it difficult to attack quantum computers.
When translating, Winternitz Vault first creates a pair of Winternitz keys and calculates the Merkle tree root (Keccak256) for the public key.
The repository is divided into two accounts: on the first, a signature is generated and the amount for transfer is fixed, and unspent funds are returned to the second account.
Each operation is accompanied by the creation of a new storage facility, and the old one is closed. This allows you to keep the keys of the main account with user funds safe.
