Question: Nevacoin is scheduled to stop accepting PoW blocks in approx 14 years. What do you think about the idea that Nevacoin remains PoW minable FOREVER?
I love it! - 74 (43.3%)
I hate it! - 44 (25.7%)
I don't know what PoW is... - 8 (4.7%)
I don't care... - 45 (26.3%)

Hi this is a party of any PoS cryptocurrency. Someone was just a slighty faster on informing the network of the new blocks discovery. Cant really avoid having conflicted blocks.

So any news on further development?

Read my comment please 2 posts above yours. @krile is studying for his final law exam due mid may so lets support him and give him some "school" time.

Tnx.

A late birthday present for Neva Smiley




The first decentralized cryptocurrency ever to be created as a gift for someone's birthday. At 1457344680 unix time is my girlfriend's 25th birthday (her name is Neva if that isn't obvious) and since she is abroad at the moment I figured this is the best gift I can give her remotely. Who wouldn't want a global decentralized peer to peer network cryptocurrency platform named after them as a birthday gift, right? Don't worry, I will also give her a less geeky gift when she comes back Smiley

Genesis block:

Code:
const char* pszTimestamp = "Happy 25th birthday Neva!!!";

        genesis.nTime    = 1457344680;
      




The coin was successfully launched on March 7th, 9:58AM (GMT) and is available for mining (for the next 14years) and staking since day one.

Name meaning:

Gender: F  Meaning of Neva: "white snow" Origin of Neva: Spanish





What is the purpose of this coin?

- 0% PoS, fixed block rewards ensure predictable supply increase.

- Unlike most of PoW/PoS Hybrids, this one will have a very long PoW phase. The network will stop accepting PoW blocks in approximately 14 years. The goal is to gain a mining chance, even to people that stumble upon it years later in the future.

- Gain some interest from the female half of the population (starting with Neva). Lets be honest the cryptocurrency community is still a sausage fest Smiley

- Blake2s mining algorithm.

- Blake2s PoS block hashing - friendly to low end hardware. Raspberry-Pi nodes...etc.

- Slow emmision. The PoW and PoS reward is 5 NEVAs. The reward will halve for both at block height 2628000. That is approximately 7 years until the first halving. After the second halving at block height 5256000 the PoW phase will be over, continued only by PoS with 1.25 NEVA reward, which will halve again in 2628000 blocks...etc.

- The low reward and long PoW phase is meant to avoid the insta-mine by handful of people.




Coin specifications:

Ticker:                       NEVA
Type:                         PoW/Pos2.0 hybrid
PoW algorithm:           Blake2s  (read more)
Difficulty retarget:       Every block
Block target:               91 seconds
Block reward:              5 NEVA  (both PoW and PoS have static rewards)
Max block size:            4MB
Coinbase maturity:      25 blocks
Block reward halving:   every 2628000 blocks (approx 7 years, probably less)
Last PoW block:           5256000 (in approx 14 years)
PoS start:                    from the first block
Minimum PoS age:        4 hours
Maximum PoS age:       no max (PoS 2.0)
Max coins:                   26 280 000 NEVAs (this amount will be reached at block 131400000, or in roughly 350 years)

Sum of the mining/staking schedule:

-Integrated block explorer
-Two themes, default light theme and an optional funky dark theme

Daemon features:
-coockie authentication
   - You do not need the rpcuser/password parameters in the nevacoin.conf to run the daemon. You can still use them if you want, but if they are not provided an authentication cookie file will be generated in the .nevacoin directory and also deleted on shutdown. So one less thing you have to do if you want to run a headles node for staking.

Basic setup for daemon in nevacoin.conf file is:
Code:

Hi everyone! I'm starting new tests for my Raspberry PI node... I'm using a very precise signal generator to run my RPI replacing the generic Crystal Oscillator with this good one, my tests show good results for overclock too. But i need some ways to tests this experiment, if all runs with success i will try to keep this node running for a long time (it was in a electronics research lab what i work), this signal generator have an rubidium oscillator internally, what makes the generated signal very precise, please someone knows some way to test if the node is really good (i already have done some stress tests with success). The setup is:

-Raspberry Pi model B;
-SMB 100A Rohde & Schwarz Signal / Microwave generator;
-Raspbian Jessie with 4.9.24+ RT kernel;
-BNC cable to transport the signal to RPI board;
-100MB Bandwidth connection but the RPI 1 limits to 10MB/s the BW;
-700MHz to 1033MHz overclocked BCM2835 CPU.

-> In the future I will start to play with RPI 3 Model B+, but for now RPI 1 sounds ok.
-> The node IP is 143.107.228.226 - Running client v1.4.0 and staking ok.

And, some pics for you:

Beautiful Cheesy

For a start I would check how the CPU handles new blocks, use a CPU usage logger or just htop and monitor what happens when a new block flies in. In this setup that is the only bottleneck I could see.

Also limit the number of connections to keep the ram usage down (maybe around 20). Once the pi starts swapping to the sd card its performance drops considerably...

@staysecure, thanks! @krile, thanks too! Sure the swap can affect negatively in the wallet processing? I'm using an class10 sdcard and now i've been incrased the cpu clock to 1,1GHz all seems very stable, the room temperature is controlled to stay at 22ºC. I'm using another setup as you can see:

Clock generator:
https://s24.postimg.org/4fvoy2lo5/raspiclock.jpg

Primary frequency standard (for all system clock reference, works with cesium beam):
https://s17.postimg.org/5cjgx3a7x/primary_frequency_standard.jpg

System setup (counters, syntethyzer, GPS, NTP server):
https://s8.postimg.org/ndno6hp45/setup.jpg

The Pi:

Clock for my BR NTP server:
https://s13.postimg.org/piefa2r5j/beagleclock.jpg

Raspberry time synchronization:
https://s17.postimg.org/pb4ph4yml/Captura_de_tela_de_2017-05-06_09-07-43.png

Raspberry CPU Clock:
https://s16.postimg.org/yie3p73mt/Captura_de_tela_de_2017-05-06_09-08-01.png

This cesium frequency standard feeds a NTP server, Raspberry with NEVA wallet, a GPS for research with time and a counter for contabilize the time difference between the GPS clock and the generated clock by cesium beam clock. All the system is locked with the cesium beam frequency standard.

I think high cpu usage will be the problem too, but for now i only have this pi  Embarrassed Cry when the univesity buy more new raspies i will pick one for this xD

Just a off topic question: someone experiencing problems to compile ccminer blake2s on new OS updates (like debian ones?), because here i'm getting an error at ssl library init... Like:

"checking for SSL_library_init in -lssl... no
configure: error: OpenSSL library required"

I already checked if libssl or openssl is already installed, i'm will put another pc with an nvidia quadro to give extra mining but this machine contains Kali linux (based in debian) with a lot of libs installed for dailly use too...
