📌 What is a low-entropy private key?




In cryptography, 'entropy' represents randomness.


A truly secure private key should be a 256-bit random number, with entropy close to 256 bits.


However, many early wallets or manually generated private keys are not; rather, they use easily memorable, highly repetitive simple numbers or phrases as input.



For example:




  • 0x0000000000000000000000000000000000000000000000000000000000000001


  • 0x1111111111111111111111111111111111111111111111111111111111111111


  • Or private keys generated from seeds like bitcoin, 123456, letmein.




The search space for this type of private key is extremely small, equivalent to 'having a target', making it the easiest target to collide.






💥 Case Analysis: Wallets that have been cracked




Let's look at a few real cases:




  • Private Key: 0x1

    Address: 1BgGZ9tcN4rm9KBzDn7KprQz87SZ26SAMH

    Has been tested and withdrawn multiple times, confirming loss of control


  • Private Key: 0deadbeef... (a test value favored by programmers)

    Also previously scanned in bulk for balance


  • Private keys generated from birthdays or simple passwords, e.g., password123, 19900101, etc.

    Many old brain wallets used this method, and have been recorded and marked as 'high risk' in multiple databases.







🚀 How does GoldenKey optimize collision efficiency?




GoldenKey's private key collider focuses on strategic collisions, not blind scanning:




  2. Built-in low-entropy dictionary library

    Includes thousands of common 'weak private key' templates, cracking phrases, brain wallet derivation patterns, etc.


  4. Analysis of known wallet libraries

    Integrates community publicly leaked data, historical collisions, transaction activity, etc., to prioritize high-probability addresses accurately.


  6. Dynamic entropy value judgment + weight scoring

    Real-time judgment of the 'security' and 'historical hotspots' of private key candidates to accelerate collision hit rates.


  8. Multithreading + multi-chain parallel scanning

    Supports running multiple chains like Bitcoin, Ethereum, Tron simultaneously, improving efficiency by dozens of times compared to traditional colliders.







🔐 In summary:




Not all private keys are equally secure!


Low-entropy private keys are the favorite targets of hackers; GoldenKey precisely utilizes this information for targeted attacks and quick hits.
