🔍 Lost Bitcoin: How Private Key Errors Destroy Your Funds
💥 Practical case: Analysis of the loss of 0.06605635 BTC due to generating an invalid private key. Step-by-step breakdown of fund recovery and critical vulnerabilities in the is_private_key_valid function.

📌From the theory of vulnerability it is known that attackers can use incorrect generation of private keys in blockchain systems with the determining order of the group of points of the elliptic curve secp256k1. Let’s move on to the practical part of the article and consider an example using a Bitcoin wallet: 1vdbVPC6Ts9d5WhRDriPdndvvCwmCbKCj

🔑 The main issue: Errors in calculating the order of the secp256k1 group lead to private keys being created outside the valid range [1, N). This causes:

Generation of 50% invalid keys in Bitcoin wallets

Irrecoverable loss of funds (keys fail ECDSA validation)

Risk of compromising HD wallets and smart contracts
