[PASC] PascalCoin: Induplicatable NFT

[adaseb]

2.3G = 5GPU, not 50

With varience and difficulty still going up, you might mine for 24 hours with 5 GPUs and not find a single block.

[moooonu]

The first Alt-coin designed to work without a historical operations requirement, yet is still able to control double spending or check balance. Through an ingenious take on Blockchain technology, PascalCoin is the first coin to be independent of historical operations while solving the problem of Double Spend Technically, Pascal Coin uses a SafeBox hash, modified each time a new block is generated in the blockchain. When this happens, SafeBox is updated with block operations, and then generates a new "SafeBox hash". After this, the entire blockchain could be deleted without losing double spending efficiency, because the balance of each account is included in the SafeBox hash. SafeBox size is growing, but only 5 new accounts are created per block to control the size. No ICO, No premine, 100% fair distribution Pascal Coin is cryptocurrency for humans, not only for geeks Pascal Coin is an "easy to understand" and "easy to work with" Crypto, because it is very similar to a bank. Using "easy to remember" accounts instead of cryptographic address's, and everybody will need have a personal account to receive/send coins: Example of address in Bitcoin: 1LpwTz4WWT35q1jr47rU5XhkuCvBrd561k Example of account in PascalCoin:  12345-54 <-- Easy to remember! Please read the Pascal Coin concept at White Paper: https://github.com/PascalCoin/PascalCoin/blob/master/PascalCoin%20White%20Paper%20-%20EN.pdf It's name is "Pascal Coin" due it's written from the scratch in Pascal language.

I think an Android App will be cool to support coin and people to keep their coins in hand

Just an advice. your coin your wish your dev.

How can I know real network hashrate? Block explorer shows 266 Gh. If RX480 gets about 550Mh, then we have about 500 cards (266000/550) mining for the whole network. That is NOT true, real number must be much, much higher. So, where can we get it?

Current target is 000000000004..... or so

So 211106232532992 hashes to find a block or so.

However next few hours this figure will probably keep going up.

With ~2.3 Gh/s or so you will find a block within 24 hours.


So don't mine unless you got 50 GPUs or so.

I have 100+ gpus, about 40Gh total hashrate, mining with v0.2 and not seeing any blocks for hours. That's why I asked. And questions remains:
1. Where do you get current target?
2. How do you get those 2111.... hashes from 0000... target?
3. How to calc average blocktime for a given hashrate? Divide those 2111... hashes by my hashrate and that will be "time to find a block in seconds"?

That's exactly why I ask. And again, you haven't answered my questions. All three of them. Can you help, please?..

Someone needs to make a video of how to use the new miner. I tried it, but never found any nonces. It's very confusing.

Yeaaaaahhh, i found my first block, just after few minutes

I am struggling to find blocks with it too... have found one hours ago, and that's it... node running, miners connected and hashing. May be really bad luck. Or may be there's a problem with the miner, I don't really know.

Is it possible the trading activity has had an affect on finding blocks?

Maybe we are already too small miners for this coin?

[Aetsen]

Over 335,000 MHs now so it will be very hard to find blocks unless you have a lot of GPUs. I have 3740 Pascal Coin accounts to sell. If anyone wants to buy them message me with an offer. Thanks.

OpenCL miner is here!

https://github.com/Vorksholk/PascalCoin-OpenCL/releases/download/v1.00/PascalCoin_OpenCL_ProxyMiner_v1.zip

Getting about 550 MH/s on an RX 480 with stock clocks.

For anyone thinking about CPU mining, an i7-5820k overclocked used to get about 8 MH/s.

Instructions very similar to PascalCoin CUDA Proxy miner. Here they are:

Code:

To use this miner:

1. You must already have PascalCoin installed. If you don't have it, download it from sourceforge here: https://sourceforge.net/projects/pascalcoin/. Once it is installed, run the PascalCoinWallet.exe provided in the download.

2. You must be using a 256-bit secp256k1 key. This is the default behavior of the PascalCoin wallet.

3. Your miner name must be exactly 8 characters long. The miner expects that the input is exactly 176 total bytes (which is achieved by using a secp256k1 key and a 10-character name)  NOTE: NOT 10 like before! 8 characters, because the last two will be used to identify each GPU!

4. You must have RPC enabled in your client (any port of your choosing, default is 4009)

5. You must run the proxy miner (PascalProxyv2.jar) in the same directory as the PascalCoinCUDA_ProxyMiner_smXX.exe file you run (everything is where it needs to be if you just extract the provided zip). For most people, the host should be 127.0.0.1, and the port should be 4009. Enter the same 8-character miner name you put in your PascalCoin wallet.

6. Open one or more (one for each GPU) copy of PascalCoinOpenCL_ProxyMiner.exe by cd-ing to this directory in a command prompt, and running PascalCoinOpenCL_ProxyMiner.exe. 
The miner takes four arguments: device (d), platform (p), intensity (i), and cyclesize (c). 

For example: PascalCoinOpenCL_ProxyMiner.exe d0 p0 i23 c50
would run the miner on platform 0, device 0, with an intensity of 23 and a cyclesize of 50. 

Higher intensities are more demanding on the GPU. Additionally, too high of an intensity can cause the miner to actually decrease in effective hashrate. 

The cyclesize has a minimal affect on hashrate generally. 

Unless you have a special setup (like NVidia and AMD cards in the same system), your platform is probably 0. You can determine which platform and device to use from the output at the original miner's start.

You can also run the benchmark miner (in the Benchmark folder) to try out different devices and intensity/cyclesize arguments. If you are compiling from source and want to make the benchmark version instead of the normal mining version, comment out the lines responsible for writing to the datainXX.txt file, (optionally) change the header file you read from to a single name regardless of device name, change the line

printf("Found nonce: %08x    T: %08x    Hashrate: %.3f MH/s   Total: %d\n", nonce, timestamp, (((((double)totalNonces) * 4 * 16 * 16 * 16 * 16) / (4)) / (((double)getTimeMillis() - start) / 1000)), totalNonces);

to

printf("Found nonce: %08x    T: %08x    Hashrate: %.3f MH/s   Total: %d\n", nonce, timestamp, (((((double)totalNonces) * 4 * 16 * 8) / (4)) / (((double)getTimeMillis() - start) / 1000)), totalNonces);
			
			
 and modify the .cl code by changing the lines:

		uint targetX = h0 & 0xFFFFFFFF;
		uint targetY = h1 & 0xF0000000;
to
		uint targetX = h0 & 0xFFFFFF70;
		uint targetY = h1 & 0x00000000; 

This essentially lets the code find nonces 512 times faster, and accounts for the 512-times-faster-sharerate by reducing how many hashes it expects each nonce solve to take by a factor of 512, while removing the overhead of writing files (since writing a few files a second may cause it to be slower).

If you notice your miner finding several of the same nonce, try lowering the intensity and/or cyclesize (because you're sending so much work to the GPU that it can't get a timestamp often enough, so it exhausts the 4-ish billion possible nonces (~4 GH), and starte repeating work).
