Slimcoin | First Proof of Burn currency | Decentralized Web

[gavrilo77]

Hi guys, I have been playing some time trying to compile Slimcoin daemon on Raspberry Pi (slimcoind on Raspbian headless server), and that´s my results:

v0.4.0 Compile and run smoothly but it has a warning ( "WARNING: Blockchain re-download required approaching or past V0.4 upgrade deadline") that make it run on safe mode and I can´t do almost any thing on command line console, I allways get that warning; still it updates well the blocks and stay online.

The sync allways stop on block 350. To work around that, I copied blockchain files from my Windows wallet.

v0.5.0 Compilation was allrigth, but it crashes all the time (every 3 o 5 mins). Can´t sync. Always stop on block 500. I get connecction refused, socket closed mensajes on debug.log. Need to add USE_OLDC=1 to get compiled, otherwise it is hung in the file bitcoinrpc.cpp.

That´s the step I have done (I'm not Linux expert so if you can help me I'll be very greatful):

Code:

sudo apt-get update

sudo apt-get upgrade

sudo apt-get install build-essential libssl-dev libboost-all-dev libminiupnpc-dev

mkdir Slimcoin && cd Slimcoin

wget https://github.com/slimcoin-project/Slimcoin/archive/SLMv0.5.0.tar.gz && tar xvfz SLMv0.5.0.tar.gz

wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz && tar xvfz db-4.8.30.NC.tar.gz

cd db-4.8.30.NC/build_unix

../dist/configure --enable-cxx --disable-shared --with-pic CPPFLAGS="-I/usr/local/BerkeleyDB.4.8/include -O2" LDFLAGS="-L/usr/local/BerkeleyDB.4.8/lib"
make && sudo make install

cd /home/pi/Slimcoin/Slimcoin-SLMv0.5.0/src

make -f makefile.unix USE_OLDC=1 BDB_INCLUDE_PATH='/usr/local/BerkeleyDB.4.8/include' BDB_LIB_PATH='/usr/local/BerkeleyDB.4.8/lib'

sudo ln -s /usr/local/BerkeleyDB.4.8/lib/libdb_cxx-4.8.so /usr/lib/libdb_cxx-4.8.so


Just run daemon:

./slimcoind


(Get warning mensaje about slimcoin.conf and closed but it has created wallet files) 


Now I will change the wallet files from sd to external hard drive.



mv /home/pi/.slimcoin /home/pi/hdd1

mkdir /home/pi/.slimcoin && cd /home/pi/.slimcoin

sudo nano slimcoin.conf

Create slimcoin.conf in .slimcoin folder on sd.

Good to know because ...



Hmm.

  Now my Pi is a farming Storj node and SLM burning machine 

[gavrilo77]

I dont understand something:

Explorers on slimcoin.info and Bchain.info showing different things for the same blocks?

[gavrilo77]

I have contacted B-ter to reconsider again SLM. They answered like "Thanks for the information"

Hi, today I have been done more intensive testing of Raspi Slimcoin daemon and it crash every time it try to do PoB, I think. My wallet it's encrypted, I have burnt some coins on windows client before copy Blockchain and wallet files to Raspberry. Trying to mint by burn with Pi, I unlock wallet with "./slimcoind walletpassphrase pass 100000 true" and immediately it crash.... there's last lines of debug.log:

Code:

I think all it´s correct... explorer on Slimcoin.club sometime not showing you the block you select... example: you select 1076472 and it show you "height": 1076476". Make sure it´s showing the block you desire.

Anybody are suffering the same symptoms?

If you have problem with 0.5 try 0.4 wallet, it was working very well as well

[gjhiggins]

Anybody are suffering the same symptoms?

Yes. eliteyo is.

I wonder if it's possibly due to platform+OS differences in C++ implementation:

https://github.com/slimcoin-project/Slimcoin/commit/8e9fe2c832e62ba60dc57aacef52918ba2d115fb#diff-7ec3c68a81efff79b6ca22ac1f1eabbaL5306

I doubt I can replicate on a VM. If anyone's experiencing that problem and is compiling natively for Windows, does reverting that line to the C99 macro fix it?

The Slimcoin version 0.5.0 is not working properly on any of my ARM boards (Raspberry Pi & Odroid XU4) even if I manage to compile it properly. It crashes randomly and my debugging skills got me as far as dumping a core and investigating the stack frames, but no useful thing came out of this.

My hunch is that it may have something to do with the boost libraries. But I may be wrong.

Run it through strace and gdb.

I'm looking over the block creation code (https://github.com/slimcoin/slimcoin/blob/afd8ef7e18e17f876f0bc7b44e79ee867f0b3ac1/src/main.cpp#L4931) and I'm wondering:

What is stopping miners from changing the block decay to a constant? What is stopping them from replacing that whole statement with something that makes nEffectiveBurnCoins an absurdly high number?

Someone can burn coins have them never decay D:

How often do you get PoS rewards? I staked last week and got some coins on the first day (like 47 coins with a stake of 19600) but haven't got anything in a week. Does the amount sound right as well?

You get to receive 10% of your stake yearly which is 1960 coins. It's 5.36 coins a day.

Funny thing happened. I have a dedicated Slim Burn wallet on a computer I use only for this wallet (i.e. my staking Slim wallet does not reside on this computer).  Anyway, regular and healthy sized payouts of coins had been coming in thanks to burning.

After a couple weeks the staking started up (I suppose because my wallet was unlocked).  Staking rewards suddenly started appearing.

Exactly coinciding with the onset of staking rewards, 1) my computer slowed way down and 2) the burn payouts reduced to a trickle and became smaller in size. Though I was now getting small stake returns, this didn't compensate for the huge reduction in burn payouts.  

I'm assuming I shouldn't have left the wallet unlocked on my dedicated "burning wallet/computer" because staking takes too much processor power, even for small amounts.

What I learned is not to mix burning and staking, and therefore, to always burn with the wallet locked.  

The thing I can't explain is why the onset of staking rewards would reduce burn rewards.  Although the computer was slow, it was working enough to support several other non-Slimcoin wallets that continued to get staking rewards, and I understand burning isn't processor intensive.  So I'm a bit perplexed why my burn rewards got reduced by 90%.

In have just found this doc on github about compiling bitcoin for differents platforms.


https://github.com/bitcoin/bitcoin/blob/master/doc/build-unix.md

Take a look at the section "ARM Cross-compilation".

Could anybody try it? Maybe I could try this weekend.

[psycodad]

Just wanted to report that I finally upgraded my node (daemon-only) to the latest github master branch on Debian7-amd64 without any problems.
Its running now for two days and does well so far. However, no chance of staking even with only 500 coins (brings the machine to the speed of a pocket calculator). Slimcoin is in my experience the most demanding wallet (the PoS part) compared to any other I have ran and still run.

[muf18]

Staking make is quite CPU hungry that's true, but on my PC it's like 10-15% max.
I wonder when will beta-ACME ressurect ? It has been down for days now.
