I'm willing to bet 100 BTC that ASICs will be the first mining hardware to be rendered useless by Bitcoin developers.

This is specualtive, but... Couldn't you say BIP16 killed mystery miner's botnet ring? Botnets are software, but directly use hardware. You can't have one without the other. PS: Address in sig if you're feeling like tossing 100BTC around.

I look forward to finding out about this. I think Glasswalker has one in his hands and seems to have have an idea on what he is doing. I'd like to see him test it out.

TheSeven: You will probably have to agree to make a closed source MPBM build which includes support for this firmware...

I think the idea of the commission is great, but I really wonder how many people it will turn off, because of the need for tweaked software.

I disagree. There's nothing secret about how the miner software would function. Everything is controlled by the signcryption done by the signcryption servers. The miner software would just have to first send the work to the signcryption servers to have it signed before passing it to the miners running the TML bitstream. And when a nonce is found, it would have to send it to the signcryption server to have it decrypted before it can be sent off to the pool. The signcryption server just controls that for every X nonces it decrypts, you need to send it a commission nonce.

First, my congratulations to EldenTyrell! Good luck to his project!

Another thing is what if bitfury gets the same idea and they release their 300 mh/s bitstream with 5% comission. No point in using a slower bitstream. Or even an improved open source bitstream that goes faster than 260 mh/s.

I will not do that as mine bitstream would not work with any board around there... not enough power for it and future version... So for existing spartan board I am not competitor to his bitstream niche.

But that nice is not too big, I expect that there's about 1000 more spartan chips in circulations... totaling about 1655 with our 655 thing. our question is more like - how to deploy 10'000 more spartans, not how to compete for 1000 spartans lying around.

Love the effort from the guy but I think we all know that it is going to get leaked without the commission at some point.

Same with digital copy of magazine ...

Piracy in inevitable. I think he should have sold it off initially rather than take a constant 5% cut but that is just me.

He states in his FAQ that it is possible to reverse-engineer the bitstream from the device, but that the effort to do so would require as much or more knowledge of how it worked as it took to create it in the first place, and therefore the effort would be best directed at just creating it again from scratch.

And assuming he is using robust proxies like he states he is (google and amazon), that makes the DDoS a bit less feasible. Finally, if he is using proper open encryption techniques that have been proven, and not falling into the trap of "roll-your-own" failure, it has a very likely chance of success.

By the way, I don't believe that EldenTyrell modifies the INPUT of the double-SHA.
Changing even one input bit will change all output bits in a non-trivial, seemingly stochastic, way.
After all, this is the very idea of SHA-256.

What I, however, do believe, is: Once a "golden nonce" has been found, he encrypts it. Probably quite trivially,
as his professional pride would not permit him to add extra encryption stages and thus slow the miner down. Extra stages would also impact space and power consumption.

It may be some kind of fixed XOR mask, but that would be too trivial. Maybe an XOR mask that is based on the
32-bit counter or something. Maybe an adder plus an XOR mask. Something like that.

Probably a key with the incoming job that is tested and then convoluted to produce the outgoing transform?

It makes me sad thinking of all the time he spent on this code, and the time he will spend keeping the server up that could have been spent on a better bitstream. There needs to be an open mechanism to compensate bitstream work and encourage collaborative improvements.

From what I read on his web site it seems like the jobs are what's getting signcrypted, not the golden nonces.

ET,

~~Can you clarify what approxiamately 5% means? Imprecise language regarding money makes me nervous.~~

Also, how will you harvest this 5%? If this becomes common practice how would I know some future bad actor doesn't take 5% and all valid blocks? ~~Similarly how could you be sure a user doesn't proxy your hashes back to himself? Or send them to dev/null?~~. You signature server is going to be a huge denial of service target. Will you compensate miners for downtime?

It is a fascinating idea. Do you follow behavioral economics?

Strike through on items in the FAQ.

Nice work

When will i be able to use that on my Ztex Cluster ?

I downloaded the file but i actually have no clue how to use that Sad

Enterpoint is still working on getting a basic bitstream working first. Only a few developers have boards at the moment. This will come later

This miner is available now and will do over 1g/hash with this new TLM bitstream

50 boards went out to those who asked for dev status. The question still stands. ;p

Yes and just to get back on topic here I think tricone-mining is brilliant and what E.T. did here is amazing

This brings new life to FPGA miners. Our ModMiner Quad will now do over 1g/hash per unit and thats after the TLM commission.

Well done.
