Solana Develops Quantum-Resistant Vault to Protect Users
Date: 2025-01-06 Author: Gabriel Deangelo Categories: BUSINESS
The developed blockchain-based vault uses a unique hash signature system, which allows it to effectively counter quantum attacks.
The solution, called Solana Winternitz Vault, relies on complex algorithms to generate new keys for each transaction. This approach makes attacks using quantum computers significantly more difficult by making it difficult to extract information about any public keys that are made available during the signing of transactions.
Winternitz Vault, currently only available as an option for users, does not cover the entire blockchain. When a transfer is made, the system generates a new key pair using the Winternitz algorithm and calculates the Merkle root using Keccak256 for the public key. Two accounts are then created, one of which is used to sign the transfer amount. After the transaction is completed, the remaining funds are returned to the second account.
Each time a transaction occurs, the Vault creates a new vault and closes the old one. Thus, the main keys of the account where the funds are stored remain hidden. This solution is designed to significantly improve security and protect users from the threat of quantum attacks.
Recall that in March 2024, Vitalik Buterin proposed his version of protection for Ethereum from such risks. However, in October of the same year, experts claimed that the danger of quantum attacks on cryptocurrencies was greatly exaggerated.
