Bắt đầu với một câu hỏi cụ thể để hiểu về tài sản số, cơ chế giao dịch và kiến thức cơ bản về bảo mật.
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 …
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 …
