डिजिटल मालमत्ता, ट्रेडिंग यंत्रणा आणि सुरक्षा मूलतत्त्वे समजून घेण्यासाठी विशिष्ट प्रश्नाने सुरुवात करा.
तुमच्याकडे mempool मध्ये 25 पेक्षा जास्त unconfirmed transactions ची chain असू शकते, पण wallet तरीही 25 transaction chain limit लागू करते. bitcoind -help-debug चालवल्यावर: ... -limitdescenda…
What does it mean that the security of 256-bit ECDSA, and therefore Bitcoin keys, is 128 bits? I mean, if I have approximately 2^256 possible points on the elliptic curve (thus possible publ…
For a blog that only receives occasional small amounts you probably shouldn't worry too much about it. However, if you plan to scale up, here are some things to consider: One issue with usin…
Information on current (ie, not past/public/resolved) security issues should be sent to the private [email protected] mailing list. The SourceForge list is now obsolete …
Regardless of whether you have a passphrase or not 12 words is just as secure as 24 words because the resulting public key will still require 2^128 iterations to compute its private key usin…
Grover's is related and some considerations were discussed here on Stackexchange, too. We could design a black box function to break both P2PKH and P2SH (and P2WSH, etc.) addresses in 2^80 s…
ECDSA signatures are pairs (r,s) where r=(k*G).x mod n, and s = (m + r*x)/k mod n, where x is the secret key, k is the random nonce, and m is the message. If you have two s values s1 and s2 …
