BTCD is no more

[Azeh]

Hi All,

Started up my qt wallet and just as the "Verifying database integrity" process ended got the following message

Runaway exception

A fatal error occurred.

EXCEPTION: st13runtime_error
init blockindex (): error opening database environment Corruption: bad record length
C:|Users...bitcoindark-qt.exe

Tried several times- same result.

OS is windows 7 64 bit

Presumably, same as for sync problems I'll need to download a new wallet but the link on the op https://mega.nz/#!ooZAmBwL!ghTTgRvGoa7zhoCMjxs-aJD56CGXSY17YI9cjcZ83Sw is for  an auto-conf.rar file


On the website http://bitcoindark.com the wallet link reads "Download Soon"

where can I download the QT wallet?

Thanks.

No, that is the correct wallet download. The .rar contains the QT and already which also includes the config.

Also, anyone having sync issues, download and replace your peers.dat.  Can be found on the OP in the wallet section.

Thanks Azeh for your fast reply  

Given the error I got,

Runaway exception

A fatal error occurred.

EXCEPTION: st13runtime_error
init blockindex (): error opening database environment Corruption: bad record length
C:|Users...bitcoindark-qt.exe

which of the existing files should I remove from the roaming folder before I start resyncing?


I assume I'll need at least to remove the existing wallet.dat file and replace it with an earlier back up - the wallet is backed up each day after staking. Should I choose the most recent back-up to use or would that have been affected by the runtime error?

The reason I ask is because when I last staked the wallet - on Friday - the last 3 mining rewards were all rejected. Could this somehow be related to the runtime error?

Also, given that the error wasn't a syncing error do I still need (as per step 5 on the OP) to replace the existing peers.dat with the peers.dat from here: https://yadi.sk/d/kN7-KnNsewy45


Many thanks for your help :-)

Amazing ... is that a tweet from Gavin Andreson praising Iguana, or a private chat log?

looks like a slack chat log

Congrats jl777! Some well deserved recognition from one of the bitcoin elders

[clovis A.]

I'm gonna have to go ahead and echo all of the positive sentiment regarding Gavin's comments on Iguana.

Nicely done James....great to see all of your 12-16 hour days aren't going unnoticed!  Not only is all of your hard work and long hours being recognized, your work is raising the eyebrows of some of the top Bitcoin developers on the planet. Not too shabby


peace,
clovis

works just as in plain vanilla bitcoin:

go to <debug window>
open <console> tab
enter:
walletunlock <yourpassphrase> 777
dumpprivkey <address_you_want_key_of>

privkey is printed in console

That was it!
Thank you. It worked like a charm.

Later on if I want to put the coins back to a QT wallet I do importprivkey (private key) and the paper wallet address is added to the QT wallet.
If the coins do not appear I do a wallet -rescan from the wallet's shortcut and they appear within some minutes.

d/loaded the new wallet, replaced the peers.dat file and started the new wallet but got same error message as before; I then deleted the txleveldb folder and this time no error message and the wallet started syncing from the beginning - currently approx 950K blocks still remaining.

Unless I'm getting my cryptos mixed up (as it were) I seem to remember some months ago there was a bootstrap file that could be copied into the roaming folder to speed the process up - anyone know if that's still available?

Seems as if it has some effect on Polo, not on Bittrex so far. In best case we just see a turning point for BTCD.

A few days ago they mentioned http://cryptochainer.com/dir/
It has bootstraps for many coins
You can find a btcd bootstrap up to 22 of January 2016. It's 3rd column 8th row

What is project iguana. I can't keep track of all 777's projects. Is there an elevator pitch description somewhere?

What is project iguana. I can't keep track of all 777's projects. Is there an elevator pitch description somewhere?

Iguana serves as a unified codebase for all of SuperNET's myriad services. In the foreseeable future, the Iguana platform's services will run in a Chrome app or natively via Linux, Windows (both 32-bit and 64-bit), OSX, Android and iOS. As envisioned by SuperNET lead developer JL777, Iguana will become "a one-click chrome app. It talks direct to the coin networks as a full peer. It is a polyglot client. Same code for BTC and all compatibles. Using native ramchains. This will allow direct integration of Pangea, Instantdex, Peggy, etc., without any reliance on public nodes for anything.”

I am not sure if it's going to run natively in windows as Microsoft expressed interest in Ethereum lately.

Thanks bitkokos2 - missed that

How is iguana connected to BTCD? Is this coin just an addition to SuperNET project (s)?

How is iguana connected to BTCD? Is this coin just an addition to SuperNET project (s)?

Iguana is the platform that will put Btc, Btcd and all supernet features together. Iguana will gradually become a full Btcd client with all its features enabled: staking, teleport, pax, etc... at the same time it will also be a full Bitcoin client, or rather the best full Bitcoin client available with the best performance optimizations by far. Iguana will also include the many supernet features that will use either Btc or Btcd blockchain. So it's entirely possible that Iguana will become the most popular full Bitcoin client, figure what that will do for Btcd!

jl777: BTCD will be used when 1 minute tx time is making sense, which is a lot of time. Iguana will eventually be a full BTCD node, but that is not the first version so we will have a phase where iguana is working with the normal BTCD nodes, then when iguana is able to stake, it can coexist as full nodes alongside the normal BTCD nodes but at some point iguana will get some hardfork that wont make sense to put into the existing BTCD codebase. So we will have a three step process. Hope that makes sense

[barbierir]

Great article about SuperNet:

The role BTCD and BTC will play in Iguana:
"I think the BTC chain can be relied upon to be the most secure for the forseeable future, so think in terms of hierarchy. Things like ownership amounts we want as secure as possible. But it is slow, so we use BTC for longer term changes and a faster chain like BTCD for shorter term changes and offchain for realtime things like poker.

Week 41: 18 BTCD have been paid to 608 unique BitcoinDark addresses for successfully staking blocks 985310-995718

Thanks for staking and supporting the BitcoinDark network. Good payout considering the nice rise in the BTCD price.  I'm glad that some heavy hitters are starting to notice Iguana and James's work.  Good things ahead for BTCD!
