Are they truly 100% random (generated by hardware) or is it pseudo-random (generated by software)? Pedantic answer: No, they're not random, because the first twenty digits or so will always be zero. Serious answer: The Bitcoin client does not use any
When two unequal objects have the same hash value, this causes a collision in the hash table, because both objects want to be in the same slot (sometimes called a bucket). The hash algorithm must resolve such collisions. Reaching back into fading mem
The password must be totally random (see later sections on generation). Hardware wallets have additional protections, and it's OK that they often allow only a short PIN. This corresponds to the following password/passphrase lengths: Digits only: 20-2
In a work, there are only two elements in the block header change between hash attempts. That is, NTime and Nonce. The miner starts the nonce search to get a valid share, and there are several possibilities: 1) In a single nonce range (0~2^32-1), the
I don't fully understand your question, first a reaction on your assumption. It is indeed so that your wallet does not hold actual coins. However, consider the distinction between the terms wallet and client
Bitcoin uses both SHA-256 and RIPEMD-160 hashes. Most often a double-round SHA-256 is used, but for address generating, RIPEMD-160 is used because it generates a shorter hash value. RIPEMD-160 has a 160-bit or 20-byte hash value while SHA-256 has a 2
I posted this answer on BitcoinTalk but will copy it here for those who don't want to chase links. The following is a direct paste from that link: If you can, installing sage and using that rather than Python will make your life much easier. There is
Every so often Apple will release a list of Macs that are now considered “vintage” or “obsolete”. You’ll probably find yourself wondering what exactly Apple means by “vintage” and “obsolete”. Here is how Apple defines the terms: Vintage: Products tha
During the course of working with your git repository, you may end up backing out of operations, and making other moves that cause intermediary blobs, and even some things that git does for you to help avoid loss of information. Eventually (condition
