Quantum threat? Bitcoin is safe!

Conclusion first: Bitcoin and private keys are safe, and quantum computers can hardly shake their foundation.

The currency circle is hotly discussing "quantum breaking bits", but it is actually worrying. Bitcoin is based on the secp256k1 algorithm and relies on elliptic curve cryptography to build a security line. The public key is like a lock, which is widely publicized; the private key is like a key, which is kept secret.

Although quantum computing is powerful, the Shor algorithm is required to break elliptic curve encryption, and the conditions are harsh: 2339 quantum bits + 126 billion Tofletemen, 317 million quantum bits are required to break 256-bit encryption per day. Compared with IBM's most advanced 127 quantum bit machine, it takes millions of times to try.

Even if quantum technology doubles every year (extremely unrealistic), it will only show a tiny light in 20 years. By then, encryption technology will not stand still. Post-quantum cryptography is ready to go, and super-singular elliptic curves may become a new shield.

Therefore, there is no need to worry about the safety of Bitcoin, but rather whether or not you hold the currency. One Bitcoin may be enough for future family wealth. #小非农增幅创3年多新低 #非农就业数据即将公布 #BTC走势分析 #美联储何时降息？ #Telegram创始人获保释
