Bitcoin address derivative decryption
Hi colleagues Bitcoiners.
While studying at Bitcoin, I encountered the problem I wanted to ask: How can I determine which derivative road was created by a specific 1xxxxxxxxx Bitcoin address? In this article, I will provide insights on how to determine the derivative of the address specified.
Bitcoin address format understanding
Before immersing the output path, let’s quickly review how the Bitcoin addresses are structured. The Bitcoin address consists of eight hexagon symbols divided into three parts:
- Version : The first four characters mark the version of the Bitcoin protocol.
2.
- Arrow : The last four characters mark the Blockchain arrow.
Power Roads
Bitcoin uses cryptographic technique called Elliptical curve Diffie-Hellman (ECDH) to get private keys from public keys. The output road is based on the following rules:
- We need two shares for each phase of the outlet:
+
Public Key : x"
+
General Secret :y”
Set the Pass Road from address
Now, let’s apply these rules to establish a derivative of the address specified.
- Check that the first four characters are version number (0x …). If not, the address is unlikely to be valid.
- Pull the control amount (the last two characters) and check its integrity using tools such as the Gethash team in the terminal or by checking with a local Bitcoin client.
If both checks pass, we can pass the arrow from the other four characters:
- Take the last four characters (
xxxxxxxxxxx) as an input to our ECDH withdrawal.
- Calculate the appropriate general secret "Y" using a key such as the SECP256K1-GEN.
Once you have received the Y, you can outdo your public key "X" by making a modular exhibition with P-1 (where "P" is the maximum network unit). This will give another random number.
Example Walkthrough
Suppose we have a valid address 1234567890abcdef where:
- The first four characters are not version number.
- The control amount is correct.
- We get an arrow from XXXXXXXXXX.
Here's how we can calculate the overall secret and public key using the Python code:
Python
Import Hashlib
Define ECDH parameters
P = 1_000_000_007
Maximum network unit weight (256 bits)
Q = p * p
n = q – 1
E = 65537
d = e ** (-1)
Out of the overall secret y using the BLS signature scheme
y = hashlib.blake2b ((P, n) + ((Hashlib.sha256 (b ”) + bytes ([x])). Digest ())). Digest () [: 32]
Calculate the public key x modular display with P-1
Public_key_x = POW (Y, D, P – 1)
Derived private key y is our input for further output
`
Conclusion
In conclusion, to decipher the Bitcoin address withdrawing path, you need to be aware of the ECDH algorithm and tools such as Gethash to check the control amount. By performing these steps, you can set the output path from the specified address, which can be useful in various programs such as cash checking or private key management.
Note, however, that this is just an example and may not remove all possible scenarios or sides. When talking to cryptographic systems, always consult with experts or use reliable sources.
