[ANN][BURST] Burst | Efficient HDD Mining | New 1.2.3 Fork block 92000

[l3mmy]

ok running this on two seperate drives so generating plots on each drive...For the miner, I guess will have to run multiple instances of it in the same folder as the others...

The passworded client was supposed to be released by now...where is it?

Right here.

Sorry, I got a bit distracted there

And of course now the rate control isn't letting me post this, so it'll be yet another couple minutes.

Proof of HDD?

What an interesting concept.  What will they think of next?

www.storj.io is doing something along these lines however its getting paid for use of storage to build a decentralized cloud

Burst
Mining speed based on HDD capacity

[No logo since I can't draw]
Website: [not yet constructed]
Twitter: https://twitter.com/Burstcoin

Specs:
NXT based
POS removed
No IPO
No Premine
4 minute block time
2,158,812,800 coins total
Block reward starts at 10,000/block, then decreases 5% each month (similar to halving every 14 months, but much smoother)
Uses pocminer made for this coin

Proof of capacity(POC) mining:
Burst uses a new algorithm for proof of hdd capacity (POC) mining. Miners pre-generate chunks of data known as 'plots' which are then saved to disk. The number of plots you store is effectively your mining speed. Every block the miner will skim through the saved plots, and come up with an amount of time until it is able to mine a block if another block hasn't yet been found. After reading through the plots is complete, your hardware can idle until the block. The miner will be released a few hours before launch to give miners time to start generating plots.

How it works:
Miners generate and cache chunks of data known as 'plots', which are divided into 4096 portions known as 'scoops'.
Plots are generated by taking a public address and a nonce, then hashing it, pre-appending the resulting hash, repeating the hash-pre-append cycle many times, and then hashing the whole thing and xor'ing the last hash with the whole thing.
Plots are staggered together so chunks of the same scoop number are together, then written to disk.
Each block has a generation signature which is derived only from the previous block's generation signature and miner, so it is difficult to manipulate.
When mining, the scoop number to be used for a block is derived from the generation signature and the block height, so the miner reads all relevant scoops(each plot will have 1 relevant scoop, and staggering allows for larger sequential read with less seeking) Only 0.024% of the stored data will need to be read each block.
The generation signature is hashed with each scoop. 8 bytes are taken from the hash, then divided by a scaling factor(inverse difficulty)
The resulting number is a number of seconds. If that many seconds passes since the last block without a new one, the address/nonce combination used to generate that plot/scoop is eligable to announce a new block.
The miner's hardware can just sit idle until either that time or a new block.
The address/nonce is included in the block as proof of eligability, and the block is signed by that address.

Technically, this mining process can be mined POW-style, however mining it as intended will yield thousands of times the hashrate, and your hardware will sit idle most of the time. Continuously hashing until a block is found is unnecessary, as waiting long enough will cause any nonce to eventually become valid.

Shoddily made flow chart of the general process. Does not include caching plot to disk and retrieving them:


Release schedule:
I still have a few fixes and some testing to do, but I plan on trying to release tomorrow.
Some time before the next entry: Miner binary + source will be posted in passworded rar archive https://bitcointalk.org/index.php?topic=731923.msg8286075#msg8286075
GMT 2014 August 10 11:00 PM : Miner password will be posted, so you can start generating plots. Passworded rar of client binary + source will be posted. plain zip of miner: https://mega.co.nz/#!b0pzHajA!ERk068l5NS6kR7zdLdTgltqyPw3Z60lwAWvgXtNQNTk Passworded client: https://bitcointalk.org/index.php?topic=731923.msg8287478#msg8287478

How do you set this up exactly? A tutorial would be nice.

Why decompile when full source is included? You can easily build it yourself.

Yes, you're right, but to compile - you protect yourself, to decompile - others.
And for 100% reliability still need check the hash sum of all libraries. But it's lazy.

Can someone throw the source code on Github?

Most people seem to be doing best with something along the lines of:
java -Xmx1000m -cp pocminer.jar;lib/*;lib/akka/*;lib/jetty/* pocminer.POCMiner generate youraddressgoeshere 1 800000 500 4

Proof of HDD?

www.storj.io is doing something along these lines however its getting paid for use of storage to build a decentralized cloud

storj is a Proof of Stake coin that has a storage service attached to it. This uses hdd's for running the blockchain, so very different concept.

well Proof of Stake I do not believe is the correct definition...I would say Proof of Storage...Where as burst is Proof of Capacity.  As you do not get more SJCX by having SJCX.  you get paid for the amount of data you are storing for the network and the amount of bandwidth you are providing.  The storage service is the means of earning SJCX.  I could have 250,000,000 of the 500,000,000 SJCX coins and it would make absolutely no difference in earning more if i wasn't providing unused HDD space


So in that sense...I can fill up my HDD with your plots.  And just delete the highest number plot as I need to offer more space onto the Storj network as it gets filled.  Because I do not anticipate immediate full utilization of storj on my HDD I can use the extra un filled space for Burst leaving an amount that can be used as a buffer between the two.

This is incorrect. We don't use proof of stake.
Brustcoin is certainly very interesting though. Will have to take a look through the code.

OK, I've got mine working. For the rest of you who haven't gotten it to work yet, after generating your address, create a text file named makeplots.bat and put the following in the file:

Code:

java -cp pocminer.jar;lib/*;lib/akka/*;lib/jetty/* pocminer.POCMiner generate YOURADDRESSGOESHERE 0 800000 500 7

Then you start making plots by launching makeplots.bat.

This creates your plots which can eventually be farmed, once you have a Burst wallet address (which is like the key to the tractor).

[Oldriga]

java -cp pocminer.jar;lib/*;lib/akka/*;lib/jetty/* pocminer.POCMiner generate adress 1 800000 500 2

Work with this options
I need correct numbers for 600Gb (plots)

[Hix]

What need to do if i have 3 disk?
I need to do all of this 3 times? on each disk?

[drumingspz]

yep.  you can run all 3 instances concurrently.

or consider creating one virtual drive for mining (from free space on different drives) ... works fine for me

As I understand 800000 is 200GB (800k x 256kB).

What need to do if i have 3 disk?

You should generate different plots for each disk.
For example (~2 GB), arguments:
1) address 1 8000 500 2
2) address 8001 16000 500 2
3) address 16001 24000 500 2

[C2]

does SSD has any advantage against with regular HDD for this mining method?


Never mind. found your answer.

thats to create plots... then do you run 3 miners too?
