Questions on: hash - страница 6

While it is now considered too late for hobbyists without expensive ASIC processors to start mining bitcoins, many of the alternative digital currencies are still well suited for mining on your home PC. In this guide, we’ll take you through all you n
A common question in the field is about upgrading a certification authority running on Windows Server 2003 to use Crypto Next Generation (CNG) to support SHA256. CNG was introduced in Windows Server 2008 and higher operating systems, as a result,an u
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
This question already has an answer here: I recently heard of a new cryptocurrency (or maybe it's not new and I'm just out of the loop) called Gridcoin which uses your GPU/CPU/ASIC to do research calculations rather than "meaningless" calculations. I
The tree is both a K/V lookup tree and a Merkle tree in one, more or less. The tree is defined by looking at a 160 bit sha1 hash. The 160 bits gives 20 bytes
One compute-intensive part of the server work is creating new merkle roots. As mckoss mentions this becomes a lot faster if you only recalculate the merkle branch that is changed by the new generation transaction instead of recalculating the entire m
The proof-of-work difficulty is adjusted to keep the average time between proof-of-work blocks between 10 and 120 minutes, and within those constraints to keep the average time between all blocks (proof-of-work AND proof-of-stake together) at approxi
Just a non detailed suggestion to modify the standard bitcoin client to support multiple hash mechanisms and multiple block headers. At some point in the future (yeah I'm suggesting planning ahead again .
- snip -Danny, thank you, you've been more than helpful with my questions over the past few weeks. I've been trying to get a more in-depth understanding of how everything is working under the hood of this beast. May I ask who you are quoting "encumbe
RIPEMD-160 was used because it produces a shorter hash output. This permits bitcoin addresses to be as short as possible without compromising security. The exact reason why SHA-256 was used in combination with RIPEMD-160 isn't known
