Questions on: proof-of-work

The hashing function used in Bitcoin is deterministic, that is hashing the same input, i. e. , block header, will always result in the same output
When creating a new crypto-currency, a compromise must be made regarding the proof-of-work algorithm. Should the algorithm selected be CPU-only, or the opposite? Both options have their pro's and con's. Should the creators use an algorithm that's eas
I am having trouble finding litecoin mining specifications. I would first of all require something like this: https://en. bitcoin
The general problems you are describing are inherent flaws in PoS, but you've caught onto some of the basic principles that are going to impact the security and integrity of the cryptosystem. Anyway, even if we can't roll back in time, could we edit
A proof-of-work (POW) system (or protocol, or function) is an economic measure to deter denial of service attacks and other service abuses such as spam on a network by requiring some work from the service requester, usually meaning processing time by
What is Heat?Scientists are known to have worked for a long time to find an answer to this question. They decided at last that the manifestation of heat was caused by a weightless substance or fluid called "caloric” which flowed from a hot body to a
I think a mining process that made use of stochastic sampling of a large data set would meet the requirements you have laid out. The blockchain even provides a great data set for this. For example, let's say each nonce requires you to randomly sample
PoW needs to be hard to do but easy to verify (by a computer). There is very little left that humans are better at than computers (OCR, face and image recognition, IBM Watson [1] etc. )
It is not stored as part of the block data itself. Other clients reply with their list of hashes ahead of yours when you broadcast getblocks. From that list, each block header is downloaded and kept in the local block chain leveldb with the hash as a
