Experts recognized Solana Sui and Near as resistant to quantum attacks

Modern blockchains Solana, Sui and Near turned out to be more resistant to potential attacks of quantum computers than bitcoin and Ethereum. Mysten Labs analysts came to this conclusion, emphasizing that the use of the EdDSA algorithm makes these networks less vulnerable to hacking.

Bitcoin and Ethereum are based on the ECDSA algorithm, which is vulnerable to quantum attacks. It can be used to recover private keys from public data, especially when there is insufficient randomness in signature generation. Solana, Sui and Near, on the other hand, use EdDSA, which is based on Edwards curves. It does not require random numbers and is better suited to adapt to post-quantum cryptography.

According to Mysten Labs co-founder Kostas Halkias, the threat from quantum computers could call into question the security of all modern cryptography. He noted that governments and large corporations building cryptocurrency reserves are already thinking about protecting investments. Many agencies around the world have issued regulations requiring the abandonment of ECDSA and RSA by 2030-2035.

Ahmed Banafa, a professor at San Jose State University, said that modern quantum computers are not yet capable of hacking into bitcoin or Ethereum networks. However, according to him, it is necessary to start preparations now. The transition to new algorithms will require a hardfork with address changes and migration of funds, which may cause serious disputes in the community.

The expert recalled that such disagreements have already led to a split – as it happened in 2015 with the separation of Ethereum and Ethereum Classic. In his opinion, a similar scenario is possible for bitcoin if some users refuse to accept the changes.

Another obstacle is the huge number of wallets created in the bitcoin and Ethereum networks. If their owners do not update their accounts, it could jeopardize the security of the entire system. In the event of losses, users will tend to blame the blockchain itself, according to Banafa.

Recall that in July, a group of developers presented a solution to protect bitcoin from potential attacks by quantum computers, emphasizing the need for early response to threats.
