Questions on: mining-pools - страница 3

Pool-hopping is the practice of mining in a pool only during the good times, and leaving during the bad times; by so doing, a pool-hopper can get more out of the pool than the value he contributes to it, increasing his rewards at the expense of other
Indeed, you can consider transactions to be 'patches' against the set of unspent outputs (the UTXO set): they consume some outputs, and they create some new outputs. Blocks are aggregated patches. And indeed, to be able to undo the effects of a block
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
Summary Transactions with too low a nonce get immediately rejected. Transactions with too high a nonce get placed in the transaction pool queue. If transactions with nonces that fill the gap between the last valid nonce and the too high nonce are sen
Those shares did not solve the block, but they were a proof that a miner was trying to solve a block. The more shares, the more work needed to be put. Without shares, everyone would be essentially solo mining - there would be no way to prove that one
Ripple solves the double spend problem by consensus. Everyone who wants to run a server on the Ripple network picks a set of validators and tries to reach a consensus with them on which transactions are valid. The Ripple equivalent of Bitcoin's 51% a
You should count each share as valuable as the difficulty of the pre-determined target for that miner. If you count the actual value of the hash it found itself, either the math won't work, or you'll introduce massive variance instead of reducing it
Here is my run command: cgminer -o stratum+tcp://coinotron. com:3334 -u user -p pass --scrypt the only output in my terminal I get is (and only this): [2013-11-30 11:34:02] Started cgminer 3. 7
Does one have to manually confirm a transaction? Or do you preset it somehow to confirm only x transactions with y fees, etc? No, it's not manual. To be confirmed, the transaction must be included with the signed block when it's broadcast to the netw
Anyone holding a large amount of computing power can be seen as a potential threat to the Bitcoin Network. However, those pools have been around for a long while and their owners have earned their reputation in the Bitcoin community, so they can be m
