Solana has launched Winternitz Vault, a quantum-resistant security solution that uses a hash-based signature system to protect user funds.

Solana Winternitz Vault is currently an optional feature. According to
Decrypt, #Solana developers have implemented Solana Winternitz Vault to protect user funds from quantum computing attacks.
Solana Winternitz Vault provides additional protection against more advanced computational attacks by utilizing a hash-based signature scheme and creating a new key for each transaction.
Quantum Computers pose a significant risk to #blockchain technology, especially in terms of breaking the cryptographic algorithms that protect digital wallets. In conventional blockchain systems, public keys are revealed during transactions, which could theoretically be used by quantum computers to reverse engineer private keys. Solana's
solution solves this problem with a system that creates 32 private key scalars, each hashed 256 times to create a secure #public key. Instead of storing the full public key, only the hash is stored for verification. After each transaction, the vault automatically creates a new key, further reducing risk.
The Solana Winternitz Vault is currently optional and is not included in some network-wide security updates. In order for users to take advantage of quantum-resistant security, they must choose to store their funds in the Winternitz Vault instead of the standard Solana Wallet. As this feature remains a freely available solution, there is no indication that a network fork will occur as a result of this development.
Quantum-resistant cryptography is nothing new: back in 2019, renowned cryptographer David Chaum launched the Praxxis project. He launched a blockchain project called Praxxis that aims to combat quantum threats, but focuses on scalability, privacy, and security.

Permanent link to this post: El Salvador is buying bitcoin in store, adding up to 6,093.18 BTC to the country's Strategic Bitcoin Reserve (SBR).

El Salvador added 12 #BTC worth more than $1 million to the country's SBR in the last seven days and 44 BTC worth more than $3.7 million in the last 30 days.
#Bitcoin Country students are practicing private and #public key generation, studying bitcoin transaction data and using the ColdCard simulator.
El Salvador has bought bitcoin again, boosting its strategic bitcoin reserve to 6,093.18 BTC, equivalent to more than $523 million. The country has added 12 BTC worth more than $1 million in the past seven days, and 44 BTC worth more than $3.75 million in the past 30 days.
El Salvador's National Bitcoin Office, the country's official bitcoin tracker, is working with the country to continue accumulating BTC The purchase of 1 BTC on March 1 brought the 7-day accumulation of BTC to 12 BTC, and the 30-day accumulation to 44 BTC, for a total of 6093.18 BTC, now worth $523 million. That's more than
El Salvador recently changed its bitcoin acceptance policy to allow more flexibility, as companies are no longer required to accept crypto assets. In late January, the country's parliament passed changes to the bitcoin law by a 55-to-2 vote, removing the word "currency" from the law but keeping it as legal tender. The changes will take effect on May 1, 90 days after the law is published in the Official Gazette, and users
can accept or not accept bitcoin, but can no longer use BTC to pay taxes or government bills. In addition, Bitcoin Nation students are now practicing private and public key generation, studying Bitcoin transaction data, and learning how to use the ColdCard simulator.
Always replenished, even on weekends!
El El Salvador has replenished its strategic bitcoin reserve.

World's First Strategic Bitcoin Coin Reserves Continue to Grow and El Salvador Continues to Win,
