Bạn có thể có một chuỗi dài hơn 25 giao dịch chưa được xác nhận trong mempool, nhưng ví vẫn áp đặt giới hạn chuỗi 25 giao dịch. Khi chạy bitcoind -help-debug: ... -limitdescendantcount= Cài đặt khôn...
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 public keys),...
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 using the sam...
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 and defunc...
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 using the most...
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 single-thr...
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 for the sa...
