Seems that in the last 24 hours, almost 10% of the shares (an estimated 1.2TH/s) went to this IP address. The holder is unknown - blockchain.info at least associates it with no public pool.

Anyone know what's up here?

If there is something that will make Bitcoin succeed, it is growth of utility - greater quantity and variety of goods and services offered for BTC. If there is something that will make Bitcoin fail, it is the culture of naive fools and conmen, the former convinced that BTC is a magic box that will turn them into millionaires, and the latter arriving by the busload to devour them.

Deepbit, Slush, Eligius, Guild, Eclipse, Oz... all of them are still on the pie.
Certainly nobody able to throw around over 1TH/s has dropped off the map.

4th most shares over the last 4 days as well.

Deepbit - 213
BTC Guild - 72
Slush - 68
95.120.241.167 - 41

What does the "relayed by" mean anyway?
Isn't it just the node in the bitcoin p2p network who was the first who told blockchain about the new block when discovered?

I went through the last 5 blocks found by that ip and they all mined to a different address:

1NLq5b9FLEakfoSpRmKuUvZWBQVyHE84Wt
1B247aMR78kXn69oDEnk6VzkFadeZ67The
1QB2bGirZjGWBBcA1fTmBu2oRdhkhgikqU
1LwQKfAJhES6hqddDYimdr8sZcnKw8r442
12kWc9juGyiUaCEnVPXyRzMRX4A1BzvH2g

Not that this means anything, but if all mined to the same ip it would very strongly imply it is the same miner. Now it proves nothing (the miner could still be generating a fresh address for each block).

This is ASIC from Hell.
Its operator is known as Beelzebub.
He is testing new toy. Grin

Small calculation,
4 days * 24 hours/day * 6 blocks/hour = 576 blocks per 4 days.
41/576 blocks = 7.12% of total hashing power of the network.
Impressive :-)

They have been around for a while. Probably a semi-private pool for some big producers. It's a sticky dynamic IP from Telefónica de España, which is the largest fixed phone and ADSL operator in Spain", they have a /16 of IPs for subscribers.

Bonus points if you can find their Bitcoin port or a web interface; they haven't found a block for a while and aren't connected to blockchain.info right now.

Here's the address where most of the generates were being sent through...http://blockexplorer.com/address/1P9zu23E131FR9eTubaSt6WExmcs5zAGSx, now scattered to dozens of addresses..

Which raises an interesting point ... mining is a highly non-linear activity (i.e. revenue
garnered through mining can immediately be re-invested to grow capacity further).

Given enough time, and unless they're somehow regulated, or unless some deep innovative
disruption occurs, economic processes with this attribute have a very strong tendency to produce
monopolies or near-monopolies: one or two entities win the race, the rest of the ecosystem dies off
because they can't take the heat.

So ... in practice, what happens when someones (not necessarily a pool, btw, it could) overtakes
everybody else at the mining game ? Ding ... we're back  to a paypal/paxum/dwolla type system,
where the very large mining operation replaces the central exchange Sad

One more thing I suspect bitcoin will have to somehow overcome.


Eventually there won't be enough profit in it and mining will be done by those who have high transaction volume.

Eventually there won't be enough profit in it and mining will be done by those who have high transaction volume.
Bitcoin mining will evolve to a market where it's not just about transaction volume. Some miners will ask for a higher fee and some for a lower one. The ones who ask for lower fees get higher volumes but have a smaller profit margin and vice versa.

My point is that some miners will survive even without high transaction volume if there are enough users who want to pay a higher fee to make sure their transactions will be included in the next block.

To znort987 and others:

Personally I don't believe Bitcoin mining will ever become excessively centralized, for many reasons. One of the reasons is that some of us have fixed electricity costs, it's almost impossible for any large scale operation to make mining with fixed electricity cost non-competitive. It is not realistic for a large mining operation to be able to mine that cheaply even if they manage to somehow acquire the hardware itself for cheaper than the regular joe.

In Finland there is often a fixed electricity cost (included in rent) for student apartments, but those are usable for small mining operations only. You have to also take into account that many small time miners do not have any extra costs for the space, cooling systems etc. For a large mining operation that is a totally different story.

Then there is the fact that some people actually heat their cabins or houses with Bitcoin mining hardware these days. The added benefit of the heat makes it very difficult for the mining to become overall non-profitable. I believe a large percentage of our current mining power is people who just have their desktop PC's video card mining bitcoins or something like that. Then another large percentage of small to medium size mining operations. Large operations are a small minority of the total hashing power.

This will change in the future though, large operations will have a bigger share and the "single miners" a smaller share but I find it difficult to believe that small and medium sized mining operations can be ever driven away entirely, especially if they have the edge of fixed electricity cost or no extra cost for space and cooling, or if they are using the heat for something useful. I'm currently mining with fixed electricity cost and I have no additional costs. Mining profitability would basically have to be bad enough that it doesn't beat my hardware's rate of decline in resell value or the risk of hardware failures, for me to stop.

Going FPGA and then ASIC doesn't change anything either, I'm already considering investing in FPGA's. They are actually much more convenient in many ways compared to a traditional rig. Bottom line is that Bitcoin mining is not that different from any other modern business. Large operations will have a bigger role in the future but small and medium sized operations won't go away either.

I also wouldn't make large scale mining the devil. It's important to understand that running an operation like that involves much bigger risks as well. They have the biggest incentive of all to keep it running smoothly and profitably. That is why I'm not really worried if the Bitcoin mining network becomes a bit more centralized than it is now. If it does turn out to be a problem, I bet there will be solutions as well.

A bigger problem for Bitcoin, by a magnitude of 100, is the centralization of mining pools. That is in my opinion way more significant than worrying about the centralization of mining itself. I have seen tremendous development in this area though, Deepbit is much smaller now than it used to be and we have innovative new pools such as p2pool which has been very successful.

I'd say the future is looking bright.
