[ANN] Datacoin - Censorship-Free Data Storage

[Chicago]

If no one wants to close the pools and help lower the diff, perhaps the only other option is to hardfork....have to say that most coins i see hardfork, usually die quite soon afterwards thou, so thats not an option i would vote for....

The development agenda does include activating protocol which was never enabled for us during the upgrade from 0.8 to 0.16.

I've spoken briefly about it in the past.


We can simply build clients with updated chain parameters (in source) and require miners to eventually create blocks in the new format (the regular upgrade process we skipped which uses IsSuperMajority and BIP 9 deployment).

This is at a standstill right now and has been for me ever since the 0.16 code failed to run and mine for the testnet.

Does anybody know why the 0.16 testnet failed to mine?

Can't help you, i can#t even get in to compile.

For Ubuntu 18/Mint 19, if you're working from a clone of https://github.com/datacoinproject/datacoin.git, you'll need:

Code:

pushd ./src/madpool
protoc --cpp_out=. protocol.proto
mv ./protocol.pb.cc ./protocol.pb.cpp
popd

I guess I could update the repos if we can assume that everyone's compiling with modern Linux distros.

Where can I get the windows compiled version of the Datacoin Core 0.16.3 wallet? I am happy to compile on Ubuntu and help with testing, if required

is using wallet v0.8.6.0 still ok?

Hi Mafia!


Have you been helped?

The most recent builds I personally run are the following:

Source code DTC 0.15.99-08: https://yadi.sk/d/nA7f5cWr3VSYDf
Windows binaries 0.15.99-08: https://yadi.sk/d/eu7rJ9EN3VSYBF

The main sight has this:
https://github.com/datacoinproject/datacoin/releases/tag/v0.16.3

Does anyone else have anything more recent or better?


Many thanks all!

Hi,

Guys, are you able to compile with Ubuntu 18?

I needed to upgrade pool machine from 16 -> 18 and with new openssl there are serious problems with compile:

Good Morning,

Have anyone compiled Datacoin v0.16.3 on Ubuntu 20.04 successfully?

It seems like I have all the dependencies installed to compile the four executable files for Datacoin v0.16.3. I received no warnings or errors after make and is now waiting for make clean to complete before I will be able to test.

Will let you know if all went well later today.

Tnx,

H

Hi,

Compiled Datacoin v0.16.3 on Ubuntu 20.04 successfully and will now attempt a cross compilation for windows.

Notes;

Berkeley DB4 will produce an error.
Compile with --with-incompatible-bdb to make use of Berkeley 5.3.28 (September 9, 2013).
Madpool fix still required for compiling.
Instal QT5 to produce a GUI.
Tnx to gjhiggins for removing the warning notification when accessing the in wallet Blockchain.

Will keep you posted on the progress.

Thx,

Hi,

  Datacoin 16.3 wallet receive transferred funds from any other client tried.

  Datacoin 16.3 wallet sending funds does not work.

  Any one running Datacoin 16.3 and have a balance available - please send some DTC to dEnvzaRgyPtR2mZLPwTwN7LgpasN9rJ42H and post the amount and address here for a refund. Add your Datacoin 16.3 ip here to see if these clients want to speak to each other.

  Windows Binaries put on ice until sending can be sorted out.

Tnx,

H

Hi,

Successfully Cross Compiled Datacoin v0.16.3.0-74075b1f3-dirty Windows Binaries on Ubuntu 18.04

Notes;

Patch file for czmq and mingw32 required to cross compile.
Compile with --with-incompatible-bdb and --with-gui=yes

Running -reindex now and then tests will begin between wallets and previous wallets - let me know if you want to be part of this.

Will keep you posted on the progress.

Just trying it too.
Ryzen 1800x, Crucial ssd, 16GB, says at least 12 hours to resync.....WTF !
Will see how it goes.

Update, nearly 2 hours gone by and now says 3 days time to complete.....i think THE biggest upgade anyone can make to this wallet is the syncing, it IS, and always has been crap !!!
Seriously, i can download a new Litecoin wallet, and the whole blockchain)or do i full resync) in less than 7 hours, and thats with  hdd, not an ssd...poor form

Hi Team!

I spun up a VM to help test Datacoin v0.16.3.0-74075b1f3-dirty Windows -- it's currently syncing.
Not enough information yet from it to comment on anything -- will run some tests when it syncs.

In regards to speed, were the improvements from 0.15.99-08 incorporated?
The speed of that build was incredible and was under 12 hours to sync or rebuild -- I use that build on my production computers.

I'm here to help as best I can!

Hi Team!

The first test of Datacoin v0.16.3.0-74075b1f3-dirty Windows is complete.

The sync took 9 hours from beginning to end on a duocore Intell XeonR CPU E5-2673 v4 @ 2.3GHz with 4 GB RAM.

That's inline with 15.9, and perhaps even a bit better

The start was shaky, header sync stalled 4 times and I had to restart the instance.


Log below:

6:40 found 2 nodes within a minute in all cases

6:45 syncing headers to 22.6% quickly, stopped (no spike in cpu or ram, connections were there)
 
7:04 restarted dc and it went to 22.9 but immediately stopped syncing headers

7:10 restarted, went to 23.1 and stopped syncing headers

7:14 restarted
went solid to 87% header sync then cpu spiked and it powered through to 100 sync all headers at 7:48

7:48 all headers synced -- block now syncing with network, wallet estimates 15 hrs.
still synced to 2 peers.

8/9/20
12:19am
now has 4 peers

2:48
90% progress
 
3:45 fully synced at 1.8 gig ram.
shut down wallet and restarted (per best practice after a full sync).
ram now at 1.2 ram


IP of the test wallet is 40.87.106.229

Tests will continue!

Great work Hamburger -- let me know how I can be of continued help
