Al su se svi nakacili na FTC 8G mreza
 
A kako ja da podesim reaper da kopa feathercoin to nije mi jasno
 
Jeste jasno mi je to za litecoin radi kao sat ali probao sam feathercoin da kopam preko njega nece da startuje nikako izgleda treba da se pravi CONF fajl za njega
svaki savet primam samo vi recite ako znate
 
Poslednja izmena:
E pa ako ti je jasno za LTC i ako si tako radio onda lepo ne diras tu nista u reaperu vec samo u guimineru napravis novi proxy sa adresom i portom tog pool-a. Jednostavnije ne moze ;)
 
mislim da je cointron bagovit i da zeza sa stratumom, citao sam po forumu da se developeri zale na taj pool u globalu
 
Sto da zeza kad radi? Reaper ne moze da radi na pool-ovima sa stratumom i to je to. Kad dignes stratum na guimineru resio si problem i sljaka kao sat.
I za FTC vazi sve kao i za LTC. Covek je pokusao da podesava reaper i nije hteo da radi jer je preskocio stratum. U principu nije trebao da dira u reaperu nista vec samo da promeni port na proxy-ju na 3335 i to je to ;)
 
Ma zeza zale se oni koji koriste cpuminer, coinotron koristi neka leva podesavanja u stratum protokolu
 
To je vec neka druga prica i drugi problem, nema veze s ovim.
Ali, zar iko kopa scrypt cpu-om?
 
@[SAJ]ber Kurajber hvala ti puno dobro si rekao ja sam zaboravio da pokrenem stratum proxy sad radi bez nikakav problem

Znam ali cemu kad potrosi struje vise nego sto zaradi?

Znao sam odmah sta je problem, zato sam te pitao za proxy. Nema na cemu ;)
 
evo nekih vesti



Feathercoin 0.6.4.3 released with Advanced Checkpointing
ACP Press Release

Today we are proud to announce the release of Feathercoin with Advanced Checkpointing (ACP). Currently the checkpointing is set to be 5000 blocks behind the current block so it is effectively turned off. Checkpointing will be set to automatically checkpoint the latest block on September 2nd at 09:00UTC. This gives people a chance to update to the latest version before ACP is fully enabled.

Please download the latest client from the link below.

[size=12pt]Advanced Checkpointing FAQ[/size]

What is checkpointing?
Checkpointing was originally built in to Bitcoin in order to prevent dishonest people reversing transactions and taking back the money they had sent. Imagine someone sends you money and you dispatch goods only to find that they have taken the money back out of your account.

The basic checkpointing feature in Bitcoin makes sure that the software only connects to the blockchain defined by the developers. This is a safety feature to stop malicious users from trying to force clients on to a different blockchain. The blockchain has all the Bitcoin transactions of Bitcoin written into it. Every block in the blockchain has a unique string of characters called a hash. In the client the checkpoints are defined by providing the block number and its hash, this is then compiled and distributed. Clients will only accept the blockchain that has the corresponding block number and hash defined in the code. Checkpointing offers some protection against attackers but only up to the last checkpoint. So malicious users could try to orphan blocks after the last checkpoint and reverse transactions with 51% attacks.

What is a 51% attack?
As the network is decentralised the blocks that make it into the blockchain need to be agreed upon by the majority of the miners. So if someone has 51% of the network mining power they are able to dictate which blocks get accepted. Typically a 51% attack is used to force the network to accept alternative blocks to ones that have already made it into the chain. The result of this is to make the transactions in the original blockchain disappear. Typical clients will broadcast the transaction again but the attacker will make sure that their transaction disappears. The aim of this sort of attack is typically to reverse transactions. As these attacks orphan the original blocks, pools and miners also find that the coins they mined disappear. The victims of these attacks are the recipient of the attacker's transaction and the miners whose mined coins from the original blocks will disappear.

What is Advanced Checkpointing?
Advanced Checkpointing allows us to send out checkpoints without having to redistribute the Feathercoin software. This works by having a 'master node' which checkpoints each block it sees on the network protecting it from the attacker. This checkpoint is then picked up by all the other clients on the network which will then ignore any blocks generated by a 51% attack. This protects merchants from transaction reversal and miners from losing their newly minted coins. With Advanced Checkpointing, Feathercoin becomes the most secure of all the Scrypt cryptographic currencies.

Why doesn't Bitcoin or Litecoin have this protection?
51% attacks have generally been theoretical and in the past they have only happened a handful of times to newly born coins. However it appears that the cryptocoin landscape is becoming increasingly hostile as people invest in larger and more expensive mining farms and have access to large mining pools. The attacks that were theoretical are now becoming commonplace to coins which do not have a large amount of hash power.

Bitcoin and Litecoin have never been subjected to successful 51% attacks as their hashpower has so far been too great for the attackers to target. It would seem that as they have not suffered from these attacks then it is not a problem for them but we believe this complacency is the biggest threat. It may be true that Bitcoin is safe for now but all crypto currencies should have some concern for this issue as hash power should never be taken for granted. Litecoin could well find itself subject to such attacks especially as Scrypt hash power is becoming increasingly mobile with the advent of multipools which switch their miner's hashpower to the most profitable coins at the time.

Feathercoin in the past has been subjected to 51% attacks and even though we have enough hash power at the moment to thwart these attacks, that does not mean that the attackers will not have the resources to attack us again in the future. In fact it could be seen as irresponsible if Feathercoin did not come up with some kind of protection against these attacks as our hash power may drop or the attackers may get greater resources.

Is this a centralised solution?
ACP is a form of centralisation that we have put in place because we believe security comes first. Attacks on this new breed of crypto currencies are on the rise with the attackers becoming more and more resourceful. We are the first Scrypt based coin to respond to this threat by recruiting the best minds in this domain to ensure everyone is protected even those who engage in speculative mining and to whom we owe a debt of gratitude for their patience and understanding.

How will Feathercoin continue to innovate to ensure security and decentralisation?
This is the hard work that needs to be done and we will continue to listen to our community and innovate on the design and implementation of the ACP. We believe that Feathercoin should be powered by the community.

This is a form of centralisation as the checkpoint master node is deployed and maintained by the lead developer Peter Bushnell. Currently no other person has access to this system but it is planned to make the checkpointing system distributed over time. Distributing this system would allow several stakeholders like mining pools to have a vote on which block gets checkpointed. The controls in the system are very limited and only allow the developer to change the depth at which the blocks are checkpointed. This is an automated process and there is no facility to pick and choose which blocks get checkpointed.
 
Za 15-ak sati, cisto da imate info :) Gre'ota je da se ne uleti!

Svasta... Ovaj link koji sam napisao je do sada bio tacan... nista, videcemo sutra u podne.
 
Voleo bih da si u pravu :smash:
 
Pricaj mi o tome, isplativost u odnosu na BTC sa 2.42 bi skocila na 10! :D
 
Pazite se orpah-ta u narednom periodu, sto LTC ima veci diff multipool i ostali ce napadati shit coin-e kad im opadne diff, jednostavno coin sa brzim blokom i malim diff kad ga napadne 10x jaca mreza proizvodi tonu orphant-a i nebude profitabilan...

koliko ovo vazi za FTC videt cemo, ali shit coin-i sa brzim blokovima koje napdaju na niskom diff ce biti orphant gang bang

u prevodu ako je block prebrz nemozes ti natarat mrezu da da 5-15x vise, mozes do 2-3x sve u zavisnosti od brzine predvidjenog bloka

inace middle pool se povecao na preko 1200Mh, za multi pool neznam, ali znam da vise uopste nisu profitablniji od LTC-a jer su shit coini postali cisto groblje
 
Poslednja izmena:
cista sreca, cenu regulise par njih (fontas, itd) nema sanse da previdis sta su zamislili, navuku te par puta da zaradis 10-15% i onda te unazade 150% :)

cak je i fontas izjavio da se rado igra sa FTC-em ali da ne ocekuje ama bas nista od njega na duzem periodu, a po buy/sell orderu jasno se vidi da su samo kapitalne grupe u igri
 
Poslednja izmena:
Sta se desava sa FTC diff-om...juce je bio 206, pa je pao na 201 za 4 sata, pa je pao na 194 za 4 sata, pa ce sada opet pasti na 186 za 4 sata...

Cudne su brze promene...da nije nekakav napad?
 
ma ok ali kada pada diff onda je potrebno vise vremena da se blokovi rese...tako da pad sa 206 na 196 bi trajao bar 12 sati, kada ide sa 196 na 206 onda nekih 8 sati (proporcionalno gledano).
 
Tu negde je +- 2 sata ali su u svakom slucaju prebrze promene diffa zadnjih 24 sata
